\H{cl-2.xx} NASM 2 Series
|
|
|
|
The NASM 2 series supports x86-64, and is the production version of NASM
|
|
since 2007.
|
|
|
|
\S{cl-2.14} Version 2.14
|
|
|
|
\b Fixed buffer underflow in float parsing.
|
|
|
|
\b Added \c{SGX} (Intel Software Guard Extensions) instructions.
|
|
|
|
\b Added \c{+n} syntax for multiple contiguous registers.
|
|
|
|
\b Fixed \c{subsections_via_symbols} for \c{macho} object format.
|
|
|
|
\b Added the \c{--gprefix}, \c{--gpostfix}, \c{--lprefix}, and
|
|
\c{--lpostfix} command line options, to allow command line base symbol
|
|
renaming. See \k{opt-pfix}.
|
|
|
|
\b Allow label renaming to be specified by \c{%pragma} in addition to
|
|
from the command line. See \k{mangling}.
|
|
|
|
\b Supported generic \c{%pragma} namespaces, \c{output} and \c{debug}. See
|
|
\k{gen-namespace}.
|
|
|
|
\b Added the \c{--pragma} command line option to inject a \c{%pragma}
|
|
directive. See \k{opt-pragma}.
|
|
|
|
\b Added the \c{--before} command line option to accept preprocess
|
|
statement before input. See \k{opt-before}.
|
|
|
|
\b Added \c{AVX512} \c{VBMI2} (Additional Bit Manipulation), \c{VNNI} (Vector
|
|
Neural Network), \c{BITALG} (Bit Algorithm), and \c{GFNI} (Galois Field New
|
|
Instruction) instructions.
|
|
|
|
\b Added the \c{STATIC} directive for local symbols that should be
|
|
renamed using global-symbol rules. See \k{static}.
|
|
|
|
\b Allow a symbol to be defined as \c{EXTERN} and then later
|
|
overridden as \c{GLOBAL} or \c{COMMON}. Furthermore, a symbol declared
|
|
\c{EXTERN} and then defined will be treated as \c{GLOBAL}. See \k{extern}.
|
|
|
|
\b The \c{GLOBAL} directive no longer is required to precede the
|
|
definition of the symbol.
|
|
|
|
\b Support \c{private_extern} as \c{macho} specific extension to the
|
|
\c{GLOBAL} directive. See \k{macho-pext}.
|
|
|
|
\b Updated \c{UD0} encoding to match with the specification
|
|
|
|
\b Added the \c{--limit-X} command line option to set execution
|
|
limits. See \k{opt-limit}.
|
|
|
|
\b Updated the \c{Codeview} version number to be aligned with \c{MASM}.
|
|
|
|
\b Added the \c{--keep-all} command line option to preserve output
|
|
files. See \k{opt-keep-all}.
|
|
|
|
\b Added the \c{--include} command line option, an alias to \c{-P} (\k{opt-p}).
|
|
|
|
\b Added the \c{--help} command line option as an alias to \c{-h} (\k{syntax}).
|
|
|
|
\b Added \c{-W}, \c{-D}, and \c{-Q} suffix aliases for \c{RET}
|
|
instructions so the operand sizes of these instructions can be
|
|
encoded without using \c{o16}, \c{o32} or \c{o64}.
|
|
|
|
\S{cl-2.13.03} Version 2.13.03
|
|
|
|
\b Added AVX and AVX512 \c{VAES*} and \c{VPCLMULQDQ} instructions.
|
|
|
|
\b Fixed missing dwarf record in x32 ELF output format.
|
|
|
|
\S{cl-2.13.02} Version 2.13.02
|
|
|
|
\b Fix false positive in testing of numeric overflows.
|
|
|
|
\b Fix generation of \c{PEXTRW} instruction.
|
|
|
|
\b Fix \c{smartalign} package which could trigger an error during
|
|
optimization if the alignment code expanded too much due to
|
|
optimization of the previous code.
|
|
|
|
\b Fix a case where negative value in \c{TIMES} directive causes
|
|
panic instead of an error.
|
|
|
|
\b Always finalize \c{.debug_abbrev} section with a null in
|
|
\c{dwarf} output format.
|
|
|
|
\b Support \c{debug} flag in section attributes for \c{macho}
|
|
output format. See \k{machosect}.
|
|
|
|
\b Support up to 16 characters in section names for \c{macho}
|
|
output format.
|
|
|
|
\b Fix missing update of global \c{BITS} setting if \c{SECTION}
|
|
directive specified a bit size using output format-specific
|
|
extensions (e.g. \c{USE32} for the \c{obj} output format.)
|
|
|
|
\b Fix the incorrect generation of VEX-encoded instruction when static
|
|
mode decorators are specified on scalar instructions, losing the
|
|
decorators as they require EVEX encoding.
|
|
|
|
\b Option \c{-MW} to quote dependency outputs according to Watcom
|
|
Make conventions instead of POSIX Make conventions. See \k{opt-MW}.
|
|
|
|
\b The \c{obj} output format now contains embedded dependency file
|
|
information, unless disabled with \c{%pragma obj nodepend}. See
|
|
\k{objdepend}.
|
|
|
|
\b Fix generation of dependency lists.
|
|
|
|
\b Fix a number of null pointer reference and memory allocation errors.
|
|
|
|
\b Always generate symbol-relative relocations for the \c{macho64}
|
|
output format; at least some versions of the XCode/LLVM linker fails
|
|
for section-relative relocations.
|
|
|
|
\S{cl-2.13.01} Version 2.13.01
|
|
|
|
\b Fix incorrect output for some types of \c{FAR} or \c{SEG}
|
|
references in the \c{obj} output format, and possibly other 16-bit
|
|
output formats.
|
|
|
|
\b Fix the address in the list file for an instruction containing a
|
|
\c{TIMES} directive.
|
|
|
|
\b Fix error with \c{TIMES} used together with an instruction which
|
|
can vary in size, e.g. \c{JMP}.
|
|
|
|
\b Fix breakage on some uses of the \c{DZ} pseudo-op.
|
|
|
|
\S{cl-2.13} Version 2.13
|
|
|
|
\b Support the official forms of the \c{UD0} and \c{UD1} instructions.
|
|
|
|
\b Allow self-segment-relative expressions in immediates and
|
|
displacements, even when combined with an external or otherwise
|
|
out-of-segment special symbol, e.g.:
|
|
|
|
\c extern foo
|
|
\c mov eax,[foo - $ + ebx] ; Now legal
|
|
|
|
\b Handle a 64-bit origin in NDISASM.
|
|
|
|
\b NASM can now generate sparse output files for relevant output
|
|
formats, if the underlying operating system supports them.
|
|
|
|
\b The \c{macho} object format now supports the \c{subsections_via_symbols}
|
|
and \c{no_dead_strip} directives, see \k{macho-ssvs}.
|
|
|
|
\b The \c{macho} object format now supports the \c{no_dead_strip},
|
|
\c{live_support} and \c{strip_static_syms} section flags, see
|
|
\k{machosect}.
|
|
|
|
\b The \c{macho} object format now supports the \c{dwarf} debugging
|
|
format, as required by newer toolchains.
|
|
|
|
\b All warnings can now be suppressed if desired; warnings not
|
|
otherwise part of any warning class are now considered its own
|
|
warning class called \c{other} (e.g. \c{-w-other}). Furthermore,
|
|
warning-as-error can now be controlled on a per warning class
|
|
basis, using the syntax \c{-w+error=}\e{warning-class} and its
|
|
equivalent for all other warning control options. See \k{opt-w}
|
|
for the command-line options and warning classes and
|
|
\k{asmdir-warning} for the \c{[WARNING]} directive.
|
|
|
|
\b Fix a number of bugs related to AVX-512 decorators.
|
|
|
|
\b Significant improvements to building NASM with Microsoft Visual
|
|
Studio via \c{Mkfiles/msvc.mak}. It is now possible to build the
|
|
full Windows installer binary as long as the necessary
|
|
prerequisites are installed; see \c{Mkfiles/README}
|
|
|
|
\b To build NASM with custom modifications (table changes) or from the
|
|
git tree now requires Perl 5.8 at the very minimum, quite possibly
|
|
a higher version (Perl 5.24.1 tested.) There is no requirement to
|
|
have Perl on your system at all if all you want to do is build
|
|
unmodified NASM from source archives.
|
|
|
|
\b Fix the \c{\{z\}} decorator on AVX-512 \c{VMOVDQ*} instructions.
|
|
|
|
\b Add new warnings for certain dangerous constructs which never ought
|
|
to have been allowed. In particular, the \c{RESB} family of
|
|
instructions should have been taking a critical expression all
|
|
along.
|
|
|
|
\b Fix the EVEX (AVX-512) versions of the \c{VPBROADCAST}, \c{VPEXTR},
|
|
and \c{VPINSR} instructions.
|
|
|
|
\b Support contracted forms of additional instructions. As a general
|
|
rule, if an instruction has a non-destructive source immediately
|
|
after a destination register that isn't used as an input, NASM
|
|
supports omitting that source register, using the destination
|
|
register as that value. This among other things makes it easier to
|
|
convert SSE code to the equivalent AVX code:
|
|
|
|
\c addps xmm1,xmm0 ; SSE instruction
|
|
\c vaddps ymm1,ymm1,ymm0 ; AVX official long form
|
|
\c vaddps ymm1,ymm0 ; AVX contracted form
|
|
|
|
\b Fix Codeview malformed compiler version record.
|
|
|
|
\b Add the \c{CLWB} and \c{PCOMMIT} instructions. Note that the
|
|
\c{PCOMMIT} instruction has been deprecated and will never be
|
|
included in a shipping product; it is included for completeness
|
|
only.
|
|
|
|
\b Add the \c{%pragma} preprocessor directive for soft-error directives.
|
|
|
|
\b Add the \c{RDPID} instruction.
|
|
|
|
\S{cl-2.12.02} Version 2.12.02
|
|
|
|
\b Fix preprocessor errors, especially \c{%error} and \c{%warning},
|
|
inside \c{%if} statements.
|
|
|
|
\b Fix relative relocations in 32-bit Mach-O.
|
|
|
|
\b More Codeview debug format fixes.
|
|
|
|
\b If the MASM \c{PTR} keyword is encountered, issue a warning. This is
|
|
much more likely to indicate a MASM-ism encountered in NASM than it
|
|
is a valid label. This warning can be suppressed with \c{-w-ptr},
|
|
the \c{[warning]} directive (see \k{opt-w}) or by the macro
|
|
definition \c{%idefine ptr $%?} (see \k{selfref%?}).
|
|
|
|
\b When an error or a warning comes from the expansion of a multi-line
|
|
macro, display the file and line numbers for the expanded macros.
|
|
Macros defined with \c{.nolist} do not get displayed.
|
|
|
|
\b Add macros \c{ilog2fw()} and \c{ilog2cw()} to the \c{ifunc} macro
|
|
package. See \k{ilog2}.
|
|
|
|
|
|
\S{cl-2.12.01} Version 2.12.01
|
|
|
|
\b Portability fixes for some platforms.
|
|
|
|
\b Fix error when not specifying a list file.
|
|
|
|
\b Correct the handling of macro-local labels in the Codeview
|
|
debugging format.
|
|
|
|
\b Add \c{CLZERO}, \c{MONITORX} and \c{MWAITX} instructions.
|
|
|
|
|
|
\S{cl-2.12} Version 2.12
|
|
|
|
\b Major fixes to the \c{macho} backend (\k{machofmt}); earlier versions
|
|
would produce invalid symbols and relocations on a regular basis.
|
|
|
|
\b Support for thread-local storage in Mach-O.
|
|
|
|
\b Support for arbitrary sections in Mach-O.
|
|
|
|
\b Fix wrong negative size treated as a big positive value passed into
|
|
backend causing NASM to crash.
|
|
|
|
\b Fix handling of zero-extending unsigned relocations, we have been printing
|
|
wrong message and forgot to assign segment with predefined value before
|
|
passing it into output format.
|
|
|
|
\b Fix potential write of oversized (with size greater than allowed in
|
|
output format) relative relocations.
|
|
|
|
\b Portability fixes for building NASM with the LLVM compiler.
|
|
|
|
\b Add support of Codeview version 8 (\c{cv8}) debug format for
|
|
\c{win32} and \c{win64} formats in the \c{COFF} backend,
|
|
see \k{codeview}.
|
|
|
|
\b Allow 64-bit outputs in 16/32-bit only backends. Unsigned 64-bit
|
|
relocations are zero-extended from 32-bits with a warning
|
|
(suppressible via \c{-w-zext-reloc}); signed 64-bit relocations are
|
|
an error.
|
|
|
|
\b Line numbers in list files now correspond to the lines in the source
|
|
files, instead of simply being sequential.
|
|
|
|
\b There is now an official 64-bit (x64 a.k.a. x86-64) build for Windows.
|
|
|
|
|
|
\S{cl-2.11.09} Version 2.11.09
|
|
|
|
\b Fix potential stack overwrite in \c{macho32} backend.
|
|
|
|
\b Fix relocation records in \c{macho64} backend.
|
|
|
|
\b Fix symbol lookup computation in \c{macho64} backend.
|
|
|
|
\b Adjust \c{.symtab} and \c{.rela.text} sections alignments to 8 bytes
|
|
in \c{elf64} backed.
|
|
|
|
\b Fix section length computation in \c{bin} backend which leaded in incorrect
|
|
relocation records.
|
|
|
|
\S{cl-2.11.08} Version 2.11.08
|
|
|
|
\b Fix section length computation in \c{bin} backend which leaded in incorrect
|
|
relocation records.
|
|
|
|
\b Add a warning for numeric preprocessor definitions passed via command
|
|
line which might have unexpected results otherwise.
|
|
|
|
\b Add ability to specify a module name record in \c{rdoff} linker with
|
|
\c{-mn} option.
|
|
|
|
\b Increase label length capacity up to 256 bytes in \c{rdoff} backend for
|
|
FreePascal sake, which tends to generate very long labels for procedures.
|
|
|
|
\b Fix segmentation failure when rip addressing is used in \c{macho64} backend.
|
|
|
|
\b Fix access on out of memory when handling strings with a single
|
|
grave. We have sixed similar problem in previous release but not
|
|
all cases were covered.
|
|
|
|
\b Fix NULL dereference in disassembled on \c{BND} instruction.
|
|
|
|
\S{cl-2.11.07} Version 2.11.07
|
|
|
|
\b Fix 256 bit \c{VMOVNTPS} instruction.
|
|
|
|
\b Fix \c{-MD} option handling, which was rather broken in previous
|
|
release changing command line api.
|
|
|
|
\b Fix access to unitialized space when handling strings with
|
|
a single grave.
|
|
|
|
\b Fix nil dereference in handling memory reference parsing.
|
|
|
|
\S{cl-2.11.06} Version 2.11.06
|
|
|
|
\b Update AVX512 instructions based on the Extension Reference (319433-021 Sept
|
|
2014).
|
|
|
|
\b Fix the behavior of \c{-MF} and \c{-MD} options (Bugzilla 3392280)
|
|
|
|
\b Updated Win32 Makefile to fix issue with build
|
|
|
|
\S{cl-2.11.05} Version 2.11.05
|
|
|
|
\b Add \c{--v} as an alias for \c{-v} (see \k{opt-v}), for
|
|
command-line compatibility with Yasm.
|
|
|
|
\b Fix a bug introduced in 2.11.03 whereby certain instructions would
|
|
contain multiple REX prefixes, and thus be corrupt.
|
|
|
|
\S{cl-2.11.04} Version 2.11.04
|
|
|
|
\b Removed an invalid error checking code. Sometimes a memref only with
|
|
a displacement can also set an evex flag. For example:
|
|
|
|
\c vmovdqu32 [0xabcd]{k1}, zmm0
|
|
|
|
\b Fixed a bug in disassembler that EVEX.L'L vector length was not matched
|
|
when EVEX.b was set because it was simply considered as EVEC.RC.
|
|
Separated EVEX.L'L case from EVEX.RC which is ignored in matching.
|
|
|
|
\S{cl-2.11.03} Version 2.11.03
|
|
|
|
\b Fix a bug there REX prefixes were missing on instructions inside a
|
|
\c{TIMES} statement.
|
|
|
|
\S{cl-2.11.02} Version 2.11.02
|
|
|
|
\b Add the \c{XSAVEC}, \c{XSAVES} and \c{XRSTORS} family instructions.
|
|
|
|
\b Add the \c{CLFLUSHOPT} instruction.
|
|
|
|
\S{cl-2.11.01} Version 2.11.01
|
|
|
|
\b Allow instructions which implicitly uses \c{XMM0} (\c{VBLENDVPD},
|
|
\c{VBLENDVPS}, \c{PBLENDVB} and \c{SHA256RNDS2}) to be specified
|
|
without an explicit \c{xmm0} on the assembly line. In other words,
|
|
the following two lines produce the same output:
|
|
|
|
\c vblendvpd xmm2,xmm1,xmm0 ; Last operand is fixed xmm0
|
|
\c vblendvpd xmm2,xmm1 ; Implicit xmm0 omitted
|
|
|
|
\b In the ELF backends, don't crash the assembler if \c{section align}
|
|
is specified without a value.
|
|
|
|
\S{cl-2.11} Version 2.11
|
|
|
|
\b Add support for the Intel AVX-512 instruction set:
|
|
|
|
\b 16 new, 512-bit SIMD registers. Total 32 \c{(ZMM0 ~ ZMM31)}
|
|
|
|
\b 8 new opmask registers \c{(K0 ~ K7)}. One of 7 registers \c{(K1 ~ K7)} can
|
|
be used as an opmask for conditional execution.
|
|
|
|
\b A new EVEX encoding prefix. EVEX is based on VEX and provides more
|
|
capabilities: opmasks, broadcasting, embedded rounding and compressed
|
|
displacements.
|
|
|
|
\c - opmask
|
|
\c VDIVPD zmm0{k1}{z}, zmm1, zmm3 ; conditional vector operation
|
|
\c ; using opmask k1.
|
|
\c ; {z} is for zero-masking
|
|
\c - broadcasting
|
|
\c VDIVPS zmm4, zmm5, [rbx]{1to16} ; load single-precision float and
|
|
\c ; replicate it 16 times. 32 * 16 = 512
|
|
\c - embedded rounding
|
|
\c VCVTSI2SD xmm6, xmm7, {rz-sae}, rax ; round toward zero. note that it
|
|
\c ; is used as if a separate operand.
|
|
\c ; it comes after the last SIMD operand
|
|
|
|
\b Add support for \c{ZWORD} (512 bits), \c{DZ} and \c{RESZ}.
|
|
|
|
\b Add support for the MPX and SHA instruction sets.
|
|
|
|
\b Better handling of section redefinition.
|
|
|
|
\b Generate manpages when running \c{'make dist'}.
|
|
|
|
\b Handle all token chains in mmacro params range.
|
|
|
|
\b Support split [base,index] effective address:
|
|
|
|
\c mov eax,[eax+8,ecx*4] ; eax=base, ecx=index, 4=scale, 8=disp
|
|
|
|
This is expected to be most useful for the MPX instructions.
|
|
|
|
\b Support \c{BND} prefix for branch instructions (for MPX).
|
|
|
|
\b The \c{DEFAULT} directive can now take \c{BND} and \c{NOBND}
|
|
options to indicate whether all relevant branches should be getting
|
|
\c{BND} prefixes. This is expected to be the normal for use in MPX
|
|
code.
|
|
|
|
\b Add \c{{evex}}, \c{{vex3}} and \c{{vex2}} instruction prefixes to
|
|
have NASM encode the corresponding instruction, if possible, with an EVEX,
|
|
3-byte VEX, or 2-byte VEX prefix, respectively.
|
|
|
|
\b Support for section names longer than 8 bytes in Win32/Win64 COFF.
|
|
|
|
\b The \c{NOSPLIT} directive by itself no longer forces a single
|
|
register to become an index register, unless it has an explicit
|
|
multiplier.
|
|
|
|
\c mov eax,[nosplit eax] ; eax as base register
|
|
\c mov eax,[nosplit eax*1] ; eax as index register
|
|
|
|
\S{cl-2.10.09} Version 2.10.09
|
|
|
|
\b Pregenerate man pages.
|
|
|
|
\S{cl-2.10.08} Version 2.10.08
|
|
|
|
\b Fix \c{VMOVNTDQA}, \c{MOVNTDQA} and \c{MOVLPD} instructions.
|
|
|
|
\b Fix collision for \c{VGATHERQPS}, \c{VPGATHERQD} instructions.
|
|
|
|
\b Fix \c{VPMOVSXBQ}, \c{VGATHERQPD}, \c{VSPLLW} instructions.
|
|
|
|
\b Add a bunch of AMD TBM instructions.
|
|
|
|
\b Fix potential stack overwrite in numbers conversion.
|
|
|
|
\b Allow byte size in \c{PREFETCHTx} instructions.
|
|
|
|
\b Make manual pages up to date.
|
|
|
|
\b Make \c{F3} and \c{F2} SSE prefixes to override \c{66}.
|

|
|
must be set to \c{elf}, if \c{-f elf32} is used \c{__OUTPUT_FORMAT__}
|
|

\S{cl-0.98.09b with John Coffman patches released 28-Oct-2001} Version 0.98.09b with John Coffman patches released 28-Oct-2001
|
|
|
|
Changes from 0.98.07 release to 98.09b as of 28-Oct-2001
|
|
|
|
\b More closely compatible with 0.98 when -O0 is implied
|
|
or specified. Not strictly identical, since backward
|
|
branches in range of short offsets are recognized, and signed
|
|
byte values with no explicit size specification will be
|
|
assembled as a single byte.
|
|
|
|
\b More forgiving with the PUSH instruction. 0.98 requires
|
|
a size to be specified always. 0.98.09b will imply the size
|
|
from the current BITS setting (16 or 32).
|
|
|
|
\b Changed definition of the optimization flag:
|
|
|
|
\c -O0 strict two-pass assembly, JMP and Jcc are
|
|
\c handled more like 0.98, except that back-
|
|
\c ward JMPs are short, if possible.
|
|
\c
|
|
\c -O1 strict two-pass assembly, but forward
|
|
\c branches are assembled with code guaranteed
|
|
\c to reach; may produce larger code than
|
|
\c -O0, but will produce successful assembly
|
|
\c more often if branch offset sizes are not
|
|
\c specified.
|
|
\c
|
|
\c -O2 multi-pass optimization, minimize branch
|
|
\c offsets; also will minimize signed immed-
|
|
\c iate bytes, overriding size specification.
|
|
\c
|
|
\c -O3 like -O2, but more passes taken, if needed
|
|
|

\b Removed the "outforms.h" file - it appears to be
|
|
someone's old backup of "outform.h". version "0.98.06e"
|
|
|
|
\b fbk - finally added the fix for the "multiple %includes bug",
|
|
known since 7/27/99 - reported originally (?) and sent to
|
|
us by Austin Lunnen - he reports that John Fine had a fix
|
|
within the day. Here it is...
|
|
|
|
\b Nelson Rush resigns from the group. Big thanks to Nelson for
|
|
his leadership and enthusiasm in getting these changes
|
|
incorporated into Nasm!
|
|
|
|
\b fbk - [list +], [list -] directives - ineptly implemented, should
|
|
be re-written or removed, perhaps.
|
|
|
|
\b Brian Raiter / fbk - "elfso bug" fix - applied to aoutb format
|
|
as well - testing might be desirable...
|
|
|
|
\b James Seter - -postfix, -prefix command line switches.
|
|
|
|
\b Yuri Zaporozhets - rdoff utility changes.

\S{cl-0.98.03 with John Coffman's changes released 27-Jul-2000} Version 0.98.03 with John Coffman's changes released 27-Jul-2000
|
|
|
|
\b Added signed byte optimizations for the 0x81/0x83 class
|
|
of instructions: ADC, ADD, AND, CMP, OR, SBB, SUB, XOR:
|
|
when used as 'ADD reg16,imm' or 'ADD reg32,imm.' Also
|
|
optimization of signed byte form of 'PUSH imm' and 'IMUL
|
|
reg,imm'/'IMUL reg,reg,imm.' No size specification is needed.
|
|
|
|
\b Added multi-pass JMP and Jcc offset optimization. Offsets
|
|
on forward references will preferentially use the short form,
|
|
without the need to code a specific size (short or near) for
|
|
the branch. Added instructions for 'Jcc label' to use the
|
|
form 'Jnotcc $+3/JMP label', in cases where a short offset
|
|
is out of bounds. If compiling for a 386 or higher CPU, then
|
|
the 386 form of Jcc will be used instead.
|
|
|
|
\> This feature is controlled by a new command-line switch: "O",
|
|
(upper case letter O). "-O0" reverts the assembler to no
|
|
extra optimization passes, "-O1" allows up to 5 extra passes,
|
|
and "-O2"(default), allows up to 10 extra optimization passes.
|
|
|
|
\b Added a new directive: 'cpu XXX', where XXX is any of:
|
|
8086, 186, 286, 386, 486, 586, pentium, 686, PPro, P2, P3 or
|
|
Katmai. All are case insensitive. All instructions will
|
|
be selected only if they apply to the selected cpu or lower.
|
|
Corrected a couple of bugs in cpu-dependence in 'insns.dat'.
|
|
|
|
\b Added to 'standard.mac', the "use16" and "use32" forms of
|
|
the "bits 16/32" directive. This is nothing new, just conforms
|
|
to a lot of other assemblers. (minor)
|
|
|
|
\b Changed label allocation from 320/32 (10000 labels @ 200K+)
|
|
to 32/37 (1000 labels); makes running under DOS much easier.
|
|
Since additional label space is allocated dynamically, this
|
|
should have no effect on large programs with lots of labels.
|
|
The 37 is a prime, believed to be better for hashing. (minor)
|
|

\S{cl-0.98.03} Version 0.98.03
|
|
|
|
"Integrated patchfile 0.98-0.98.01. I call this version 0.98.03 for
|
|
historical reasons: 0.98.02 was trashed." --John Coffman
|
|
<johninsd@san.rr.com>, 27-Jul-2000
|
|
|
|
\b Kendall Bennett's SciTech MGL changes
|
|
|
|
\b Note that you must define "TASM_COMPAT" at compile-time
|
|
to get the Tasm Ideal Mode compatibility.
|
|
|
|
\b All changes can be compiled in and out using the TASM_COMPAT macros,
|
|
and when compiled without TASM_COMPAT defined we get the exact same
|
|
binary as the unmodified 0.98 sources.
|
|
|
|
\b standard.mac, macros.c: Added macros to ignore TASM directives before
|
|
first include
|
|
|
|
\b nasm.h: Added extern declaration for tasm_compatible_mode
|
|
|
|
\b nasm.c: Added global variable tasm_compatible_mode
|
|
|
|
\b Added command line switch for TASM compatible mode (-t)
|
|
|
|
\b Changed version command line to reflect when compiled with TASM additions
|
|
|
|
\b Added response file processing to allow all arguments on a single
|
|
line (response file is @resp rather than -@resp for NASM format).
|
|
|
|
\b labels.c: Changes islocal() macro to support TASM style @@local labels.
|
|
|
|
\b Added islocalchar() macro to support TASM style @@local labels.
|
|
|
|
\b parser.c: Added support for TASM style memory references (ie: mov
|
|
[DWORD eax],10 rather than the NASM style mov DWORD [eax],10).
|
|
|
|
\b preproc.c: Added new directives, \c{%arg}, \c{%local}, \c{%stacksize} to directives
|
|
table
|
|
|
|
\b Added support for TASM style directives without a leading % symbol.
|
|
|
|
\b Integrated a block of changes from Andrew Zabolotny <bit@eltech.ru>:
|
|
|
|
\b A new keyword \c{%xdefine} and its case-insensitive counterpart \c{%ixdefine}.
|
|
They work almost the same way as \c{%define} and \c{%idefine} but expand
|
|
the definition immediately, not on the invocation. Something like a cross
|
|
between \c{%define} and \c{%assign}. The "x" suffix stands for "eXpand", so
|
|
"xdefine" can be deciphered as "expand-and-define". Thus you can do
|
|
things like this:
|
|
|
|
\c %assign ofs 0
|
|
\c
|
|
\c %macro arg 1
|
|
\c %xdefine %1 dword [esp+ofs]
|
|
\c %assign ofs ofs+4
|
|
\c %endmacro
|
|
|
|
\b Changed the place where the expansion of %$name macros are expanded.
|
|
Now they are converted into ..@ctxnum.name form when detokenizing, so
|
|
there are no quirks as before when using %$name arguments to macros,
|
|
in macros etc. For example:
|
|
|
|
\c %macro abc 1
|
|
\c %define %1 hello
|
|
\c %endm
|
|
\c
|
|
\c abc %$here
|
|
\c %$here
|
|
|
|
\> Now last line will be expanded into "hello" as expected. This also allows
|
|
for lots of goodies, a good example are extended "proc" macros included
|
|
in this archive.
|
|
|
|
\b Added a check for "cstk" in smacro_defined() before calling get_ctx() -
|
|
this allows for things like:
|
|
|
|
\c %ifdef %$abc
|
|
\c %endif
|
|
|
|
\> to work without warnings even in no context.
|
|
|
|
\b Added a check for "cstk" in %if*ctx and %elif*ctx directives -
|
|
this allows to use \c{%ifctx} without excessive warnings. If there is
|
|
no active context, \c{%ifctx} goes through "false" branch.
|
|
|
|
\b Removed "user error: " prefix with \c{%error} directive: it just clobbers the
|
|
output and has absolutely no functionality. Besides, this allows to write
|
|
macros that does not differ from built-in functions in any way.
|
|
|
|
\b Added expansion of string that is output by \c{%error} directive. Now you
|
|
can do things like:
|
|
|
|
\c %define hello(x) Hello, x!
|
|
\c
|
|
\c %define %$name andy
|
|
\c %error "hello(%$name)"
|
|
|
|
\> Same happened with \c{%include} directive.
|
|
|
|
\b Now all directives that expect an identifier will try to expand and
|
|
concatenate everything without whitespaces in between before usage.
|
|
For example, with "unfixed" nasm the commands
|
|
|
|
\c %define %$abc hello
|
|
\c %define __%$abc goodbye
|
|
\c __%$abc
|
|
|
|
\> would produce "incorrect" output: last line will expand to
|
|
|
|
\c hello goodbyehello
|
|
|
|
\> Not quite what you expected, eh? :-) The answer is that preprocessor
|
|
treats the \c{%define} construct as if it would be
|
|
|
|
\c %define __ %$abc goodbye
|
|
|
|
\> (note the white space between __ and %$abc). After my "fix" it
|
|
will "correctly" expand into
|
|
|
|
\c goodbye
|
|
|
|
\> as expected. Note that I use quotes around words "correct", "incorrect"
|
|
etc because this is rather a feature not a bug; however current behaviour
|
|
is more logical (and allows more advanced macro usage :-).
|
|
|
|
Same change was applied to:
|
|
\c{%push},\c{%macro},\c{%imacro},\c{%define},\c{%idefine},\c{%xdefine},\c{%ixdefine},
|
|
\c{%assign},\c{%iassign},\c{%undef}
|
|
|
|
\b A new directive [WARNING {+|-}warning-id] have been added. It works only
|
|
if the assembly phase is enabled (i.e. it doesn't work with nasm -e).
|
|
|
|
\b A new warning type: macro-selfref. By default this warning is disabled;
|
|
when enabled NASM warns when a macro self-references itself; for example
|
|
the following source:
|
|
|
|
\c [WARNING macro-selfref]
|
|
\c
|
|
\c %macro push 1-*
|
|
\c %rep %0
|
|
\c push %1
|
|
\c %rotate 1
|
|
\c %endrep
|
|
\c %endmacro
|
|
\c
|
|
\c push eax,ebx,ecx
|
|
|
|
\> will produce a warning, but if we remove the first line we won't see it
|
|
anymore (which is The Right Thing To Do {tm} IMHO since C preprocessor
|
|
eats such constructs without warnings at all).
|
|
|
|
\b Added a "error" routine to preprocessor which always will set ERR_PASS1
|
|
bit in severity_code. This removes annoying repeated errors on first
|
|
and second passes from preprocessor.
|
|
|
|
\b Added the %+ operator in single-line macros for concatenating two
|
|
identifiers. Usage example:
|
|
|
|
\c %define _myfunc _otherfunc
|
|
\c %define cextern(x) _ %+ x
|
|
\c cextern (myfunc)
|
|
|
|
\> After first expansion, third line will become "_myfunc". After this
|
|
expansion is performed again so it becomes "_otherunc".
|
|
|
|
\b Now if preprocessor is in a non-emitting state, no warning or error
|
|
will be emitted. Example:
|
|
|
|
\c %if 1
|
|
\c mov eax,ebx
|
|
\c %else
|
|
\c put anything you want between these two brackets,
|
|
\c even macro-parameter references %1 or local
|
|
\c labels %$zz or macro-local labels %%zz - no
|
|
\c warning will be emitted.
|
|
\c %endif
|
|
|
|
\b Context-local variables on expansion as a last resort are looked up
|
|
in outer contexts. For example, the following piece:
|
|
|
|
\c %push outer
|
|
\c %define %$a [esp]
|
|
\c
|
|
\c %push inner
|
|
\c %$a
|
|
\c %pop
|
|
\c %pop
|
|
|
|
\> will expand correctly the fourth line to [esp]; if we'll define another
|
|
%$a inside the "inner" context, it will take precedence over outer
|
|
definition. However, this modification has been applied only to
|
|
expand_smacro and not to smacro_define: as a consequence expansion
|
|
looks in outer contexts, but \c{%ifdef} won't look in outer contexts.
|
|
|
|
\> This behaviour is needed because we don't want nested contexts to
|
|
act on already defined local macros. Example:
|
|
|
|
\c %define %$arg1 [esp+4]
|
|
\c test eax,eax
|
|
\c if nz
|
|
\c mov eax,%$arg1
|
|
\c endif
|
|
|
|
\> In this example the "if" mmacro enters into the "if" context, so %$arg1
|
|
is not valid anymore inside "if". Of course it could be worked around
|
|
by using explicitely %$$arg1 but this is ugly IMHO.
|
|
|
|
\b Fixed memory leak in \c{%undef}. The origline wasn't freed before
|
|
exiting on success.
|
|
|
|
\b Fixed trap in preprocessor when line expanded to empty set of tokens.
|
|
This happens, for example, in the following case:
|
|
|
|
\c #define SOMETHING
|
|
\c SOMETHING
|
|
|

\S{cl-0.98} Version 0.98
|
|
|
|
All changes since NASM 0.98p3 have been produced by H. Peter Anvin <hpa@zytor.com>.
|
|
|
|
\b The documentation comment delimiter is \# not #.
|
|
|
|
\b Allow EQU definitions to refer to external labels; reported by
|
|
Pedro Gimeno.
|
|
|
|
\b Re-enable support for RDOFF v1; reported by Pedro Gimeno.
|
|
|
|
\b Updated License file per OK from Simon and Julian.
|
|
|
|
|
|
\S{cl-0.98p9} Version 0.98p9
|
|
|
|
\b Update documentation (although the instruction set reference will
|
|
have to wait; I don't want to hold up the 0.98 release for it.)
|
|
|
|
\b Verified that the NASM implementation of the PEXTRW and PMOVMSKB
|
|
instructions is correct. The encoding differs from what the Intel
|
|
manuals document, but the Pentium III behaviour matches NASM, not
|
|
the Intel manuals.
|
|
|
|
\b Fix handling of implicit sizes in PSHUFW and PINSRW, reported by
|
|
Stefan Hoffmeister.
|
|
|
|
\b Resurrect the -s option, which was removed when changing the
|
|
diagnostic output to stdout.
|
|
|
|
|
|
\S{cl-0.98p8} Version 0.98p8
|
|
|
|
\b Fix for "DB" when NASM is running on a bigendian machine.
|
|
|
|
\b Invoke insns.pl once for each output script, making Makefile.in
|
|
legal for "make -j".
|
|
|
|
\b Improve the Unix configure-based makefiles to make package
|
|
creation easier.
|
|
|
|
\b Included an RPM .spec file for building RPM (RedHat Package Manager)
|
|
packages on Linux or Unix systems.
|
|
|
|
\b Fix Makefile dependency problems.
|
|
|
|
\b Change src/rdsrc.pl to include sectioning information in info
|
|
output; required for install-info to work.
|
|
|
|
\b Updated the RDOFF distribution to version 2 from Jules; minor
|
|
massaging to make it compile in my environment.
|
|
|
|
\b Split doc files that can be built by anyone with a Perl interpreter off
|
|
into a separate archive.
|
|
|
|
\b "Dress rehearsal" release!
|
|
|
|
|
|
\S{cl-0.98p7} Version 0.98p7
|
|
|
|
\b Fixed opcodes with a third byte-sized immediate argument to not
|
|
complain if given "byte" on the immediate.
|
|
|
|
\b Allow \c{%undef} to remove single-line macros with arguments. This
|
|
matches the behaviour of #undef in the C preprocessor.
|
|
|
|
\b Allow -d, -u, -i and -p to be specified as -D, -U, -I and -P for
|
|
compatibility with most C compilers and preprocessors. This allows
|
|
Makefile options to be shared between cc and nasm, for example.
|
|
|
|
\b Minor cleanups.
|
|
|
|
\b Went through the list of Katmai instructions and hopefully fixed the
|
|
(rather few) mistakes in it.
|
|
|
|
\b (Hopefully) fixed a number of disassembler bugs related to ambiguous
|
|
instructions (disambiguated by -p) and SSE instructions with REP.
|
|
|
|
\b Fix for bug reported by Mark Junger: "call dword 0x12345678" should
|
|
work and may add an OSP (affected CALL, JMP, Jcc).
|
|
|
|
\b Fix for environments when "stderr" isn't a compile-time constant.
|
|
|
|
|
|
\S{cl-0.98p6} Version 0.98p6
|
|
|
|
|
|
\b Took officially over coordination of the 0.98 release; so drop
|
|
the p3.x notation. Skipped p4 and p5 to avoid confusion with John
|
|
Fine's J4 and J5 releases.
|
|
|
|
\b Update the documentation; however, it still doesn't include
|
|
documentation for the various new instructions. I somehow wonder if
|
|
it makes sense to have an instruction set reference in the assembler
|
|
manual when Intel et al have PDF versions of their manuals online.
|
|
|
|
\b Recognize "idt" or "centaur" for the -p option to ndisasm.
|
|
|
|
\b Changed error messages back to stderr where they belong, but add an
|
|
-E option to redirect them elsewhere (the DOS shell cannot redirect
|
|
stderr.)
|
|
|
|
\b -M option to generate Makefile dependencies (based on code from Alex
|
|
Verstak.)
|
|
|
|
\b \c{%undef} preprocessor directive, and -u option, that undefines a
|
|
single-line macro.
|
|
|
|
\b OS/2 Makefile (Mkfiles/Makefile.os2) for Borland under OS/2; from
|
|
Chuck Crayne.
|
|
|
|
\b Various minor bugfixes (reported by):
|
|
- Dangling \c{%s} in preproc.c (Martin Junker)
|
|
|
|
\b THERE ARE KNOWN BUGS IN SSE AND THE OTHER KATMAI INSTRUCTIONS. I am
|
|
on a trip and didn't bring the Katmai instruction reference, so I
|
|
can't work on them right now.
|
|
|
|
\b Updated the License file per agreement with Simon and Jules to
|
|
include a GPL distribution clause.
|
|
|
|
|
|
\S{cl-0.98p3.7} Version 0.98p3.7
|
|
|
|
\b (Hopefully) fixed the canned Makefiles to include the outrdf2 and
|
|
zoutieee modules.
|
|
|
|
\b Renamed changes.asm to changed.asm.
|
|
|
|
|
|
\S{cl-0.98p3.6} Version 0.98p3.6
|
|
|
|
\b Fixed a bunch of instructions that were added in 0.98p3.5 which had
|
|
memory operands, and the address-size prefix was missing from the
|
|
instruction pattern.
|
|
|
|
|
|
\S{cl-0.98p3.5} Version 0.98p3.5
|
|
|
|
\b Merged in changes from John S. Fine's 0.98-J5 release. John's based
|
|
0.98-J5 on my 0.98p3.3 release; this merges the changes.
|
|
|
|
\b Expanded the instructions flag field to a long so we can fit more
|
|
flags; mark SSE (KNI) and AMD or Katmai-specific instructions as
|
|
such.
|
|
|
|
\b Fix the "PRIV" flag on a bunch of instructions, and create new
|
|
"PROT" flag for protected-mode-only instructions (orthogonal to if
|
|
the instruction is privileged!) and new "SMM" flag for SMM-only
|
|
instructions.
|
|
|
|
\b Added AMD-only SYSCALL and SYSRET instructions.
|
|
|
|
\b Make SSE actually work, and add new Katmai MMX instructions.
|
|
|
|
\b Added a -p (preferred vendor) option to ndisasm so that it can
|
|
distinguish e.g. Cyrix opcodes also used in SSE. For example:
|
|
|
|
\c ndisasm -p cyrix aliased.bin
|
|
\c 00000000 670F514310 paddsiw mm0,[ebx+0x10]
|
|
\c 00000005 670F514320 paddsiw mm0,[ebx+0x20]
|
|
\c ndisasm -p intel aliased.bin
|
|
\c 00000000 670F514310 sqrtps xmm0,[ebx+0x10]
|
|
\c 00000005 670F514320 sqrtps xmm0,[ebx+0x20]
|
|
|
|
\b Added a bunch of Cyrix-specific instructions.
|
|
|
|
|
|
\S{cl-0.98p3.4} Version 0.98p3.4
|
|
|
|
\b Made at least an attempt to modify all the additional Makefiles (in
|
|
the Mkfiles directory). I can't test it, but this was the best I
|
|
could do.
|
|
|
|
\b DOS DJGPP+"Opus Make" Makefile from John S. Fine.
|
|
|
|
\b changes.asm changes from John S. Fine.
|
|
|
|
|
|
\S{cl-0.98p3.3} Version 0.98p3.3
|
|
|
|
\b Patch from Conan Brink to allow nesting of \c{%rep} directives.
|
|
|
|
\b If we're going to allow INT01 as an alias for INT1/ICEBP (one of
|
|
Jules 0.98p3 changes), then we should allow INT03 as an alias for INT3
|
|
as well.
|
|
|
|
\b Updated changes.asm to include the latest changes.
|
|
|
|
\b Tried to clean up the <CR>s that had snuck in from a DOS/Windows
|
|
environment into my Unix environment, and try to make sure than
|
|
DOS/Windows users get them back.
|
|
|
|
\b We would silently generate broken tools if insns.dat wasn't sorted
|
|
properly. Change insns.pl so that the order doesn't matter.
|
|
|
|
\b Fix bug in insns.pl (introduced by me) which would cause conditional

instructions to have an extra "cc" in disassembly, e.g. "jnz"

disassembled as "jccnz".

\S{cl-0.98p3.2} Version 0.98p3.2
|
|
|
|
\b Merged in John S. Fine's changes from his 0.98-J4 prerelease; see
|
|
http://www.csoft.net/cz/johnfine/
|
|
|
|
\b Changed previous "spotless" Makefile target (appropriate for distribution)
|
|
to "distclean", and added "cleaner" target which is same as "clean"
|
|
except deletes files generated by Perl scripts; "spotless" is union.
|
|
|
|
\b Removed BASIC programs from distribution. Get a Perl interpreter
|
|
instead (see below.)
|
|
|
|
\b Calling this "pre-release 3.2" rather than "p3-hpa2" because of
|
|
John's contributions.
|
|
|
|
\b Actually link in the IEEE output format (zoutieee.c); fix a bunch of
|
|
compiler warnings in that file. Note I don't know what IEEE output
|
|
is supposed to look like, so these changes were made "blind".
|
|
|
|
|
|
\S{cl-0.98p3-hpa} Version 0.98p3-hpa
|
|
|
|
\b Merged nasm098p3.zip with nasm-0.97.tar.gz to create a fully
|
|
buildable version for Unix systems (Makefile.in updates, etc.)
|
|
|
|
\b Changed insns.pl to create the instruction tables in nasm.h and
|
|
names.c, so that a new instruction can be added by adding it *only*
|
|
to insns.dat.
|
|
|
|
\b Added the following new instructions: SYSENTER, SYSEXIT, FXSAVE,
|
|
FXRSTOR, UD1, UD2 (the latter two are two opcodes that Intel
|
|
guarantee will never be used; one of them is documented as UD2 in
|
|
Intel documentation, the other one just as "Undefined Opcode" --
|
|
calling it UD1 seemed to make sense.)
|
|
|
|
\b MAX_SYMBOL was defined to be 9, but LOADALL286 and LOADALL386 are 10
|
|
characters long. Now MAX_SYMBOL is derived from insns.dat.
|
|
|
|
\b A note on the BASIC programs included: forget them. insns.bas is
|
|
already out of date. Get yourself a Perl interpreter for your
|
|
platform of choice at
|
|
\W{http://www.cpan.org/ports/index.html}{http://www.cpan.org/ports/index.html}.
|
|
|
|
|
|
\S{cl-0.98p3} Version 0.98 pre-release 3
|
|
|
|
\b added response file support, improved command line handling, new layout
|
|
help screen
|
|
|
|
\b fixed limit checking bug, 'OUT byte nn, reg' bug, and a couple of rdoff
|
|
related bugs, updated Wishlist; 0.98 Prerelease 3.
|
|
|
|
|
|
\S{cl-0.98p2} Version 0.98 pre-release 2
|
|
|
|
\b fixed bug in outcoff.c to do with truncating section names longer
|
|
than 8 characters, referencing beyond end of string; 0.98 pre-release 2
|
|
|
|
|
|
\S{cl-0.98p1} Version 0.98 pre-release 1
|
|
|
|
\b Fixed a bug whereby STRUC didn't work at all in RDF.
|
|
|
|
\b Fixed a problem with group specification in PUBDEFs in OBJ.
|
|
|
|
\b Improved ease of adding new output formats. Contribution due to
|
|
Fox Cutter.
|
|
|
|
\b Fixed a bug in relocations in the `bin' format: was showing up when
|
|
a relocatable reference crossed an 8192-byte boundary in any output
|
|
section.
|
|
|
|
\b Fixed a bug in local labels: local-label lookups were inconsistent
|
|
between passes one and two if an EQU occurred between the definition
|
|
of a global label and the subsequent use of a local label local to
|
|
that global.
|
|
|
|
\b Fixed a seg-fault in the preprocessor (again) which happened when
|
|
you use a blank line as the first line of a multi-line macro
|
|
definition and then defined a label on the same line as a call to
|
|
that macro.
|
|
|
|
\b Fixed a stale-pointer bug in the handling of the NASM environment
|
|
variable. Thanks to Thomas McWilliams.
|
|
|
|
\b ELF had a hard limit on the number of sections which caused
|
|
segfaults when transgressed. Fixed.
|
|
|
|
\b Added ability for ndisasm to read from stdin by using `-' as the
|
|
filename.
|
|
|
|
\b ndisasm wasn't outputting the TO keyword. Fixed.
|
|
|
|
\b Fixed error cascade on bogus expression in \c{%if} - an error in
|
|
evaluation was causing the entire \c{%if} to be discarded, thus creating
|
|
trouble later when the \c{%else} or \c{%endif} was encountered.
|
|
|
|
\b Forward reference tracking was instruction-granular not operand-
|
|
granular, which was causing 286-specific code to be generated
|
|
needlessly on code of the form `shr word [forwardref],1'. Thanks to
|
|
Jim Hague for sending a patch.
|
|
|
|
\b All messages now appear on stdout, as sending them to stderr serves
|
|
no useful purpose other than to make redirection difficult.
|
|
|
|
\b Fixed the problem with EQUs pointing to an external symbol - this
|
|
now generates an error message.
|
|
|
|
\b Allowed multiple size prefixes to an operand, of which only the first
|
|
is taken into account.
|
|
|
|
\b Incorporated John Fine's changes, including fixes of a large number
|
|
of preprocessor bugs, some small problems in OBJ, and a reworking of
|
|
label handling to define labels before their line is assembled, rather
|
|
than after.
|
|
|
|
\b Reformatted a lot of the source code to be more readable. Included
|
|
'coding.txt' as a guideline for how to format code for contributors.
|
|
|
|
\b Stopped nested \c{%reps} causing a panic - they now cause a slightly more
|
|
friendly error message instead.
|
|
|
|
\b Fixed floating point constant problems (patch by Pedro Gimeno)
|
|
|
|
\b Fixed the return value of insn_size() not being checked for -1, indicating
|
|
an error.
|
|
|
|
\b Incorporated 3Dnow! instructions.
|
|
|
|
\b Fixed the 'mov eax, eax + ebx' bug.
|
|
|
|
\b Fixed the GLOBAL EQU bug in ELF. Released developers release 3.
|
|
|
|
\b Incorporated John Fine's command line parsing changes
|
|
|
|
\b Incorporated David Lindauer's OMF debug support
|
|
|
|
\b Made changes for LCC 4.0 support (\c{__NASM_CDecl__}, removed register size
|
|
specification warning when sizes agree).

\H{cl-0.9x} NASM 0.9 Series
|
|
|
|
Revisions before 0.98.
|
|
|
|
|
|
\S{cl-0.97} Version 0.97 released December 1997
|
|
|
|
\b This was entirely a bug-fix release to 0.96, which seems to have got
|
|
cursed. Silly me.
|
|
|
|
\b Fixed stupid mistake in OBJ which caused `MOV EAX,<constant>' to
|
|
fail. Caused by an error in the `MOV EAX,<segment>' support.
|
|
|
|
\b ndisasm hung at EOF when compiled with lcc on Linux because lcc on
|
|
Linux somehow breaks feof(). ndisasm now does not rely on feof().
|
|
|
|
\b A heading in the documentation was missing due to a markup error in
|
|
the indexing. Fixed.
|
|
|
|
\b Fixed failure to update all pointers on realloc() within extended-
|
|
operand code in parser.c. Was causing wrong behaviour and seg faults
|
|
on lines such as `dd 0.0,0.0,0.0,0.0,...'
|
|
|
|
\b Fixed a subtle preprocessor bug whereby invoking one multi-line
|
|
macro on the first line of the expansion of another, when the second
|
|
had been invoked with a label defined before it, didn't expand the
|
|
inner macro.
|
|
|
|
\b Added internal.doc back in to the distribution archives - it was
|
|
missing in 0.96 *blush*
|
|
|
|
\b Fixed bug causing 0.96 to be unable to assemble its own test files,
|
|
specifically objtest.asm. *blush again*
|
|
|
|
\b Fixed seg-faults and bogus error messages caused by mismatching
|
|
\c{%rep} and \c{%endrep} within multi-line macro definitions.
|
|
|
|
\b Fixed a problem with buffer overrun in OBJ, which was causing
|
|
corruption at ends of long PUBDEF records.
|
|
|
|
\b Separated DOS archives into main-program and documentation to reduce
|
|
download size.
|
|
|
|
|
|
\S{cl-0.96} Version 0.96 released November 1997
|
|
|
|
\b Fixed a bug whereby, if `nasm sourcefile' would cause a filename
|
|
collision warning and put output into `nasm.out', then `nasm
|
|
sourcefile -o outputfile' still gave the warning even though the
|
|
`-o' was honoured.
|
|
Fixed name pollution under Digital UNIX: one of its header files
|
|
defined R_SP, which broke the enum in nasm.h.
|
|
|
|
\b Fixed minor instruction table problems: FUCOM and FUCOMP didn't have
|
|
two-operand forms; NDISASM didn't recognise the longer register
|
|
forms of PUSH and POP (eg FF F3 for PUSH BX); TEST mem,imm32 was
|
|
flagged as undocumented; the 32-bit forms of CMOV had 16-bit operand
|
|
size prefixes; `AAD imm' and `AAM imm' are no longer flagged as
|
|
undocumented because the Intel Architecture reference documents
|
|
them.
|
|
|
|
\b Fixed a problem with the local-label mechanism, whereby strange
|
|
types of symbol (EQUs, auto-defined OBJ segment base symbols)
|
|
interfered with the `previous global label' value and screwed up
|
|
local labels.
|
|
|
|
\b Fixed a bug whereby the stub preprocessor didn't communicate with
|
|
the listing file generator, so that the -a and -l options in
|
|
conjunction would produce a useless listing file.
|
|
|
|
\b Merged `os2' object file format back into `obj', after discovering
|
|
that `obj' _also_ shouldn't have a link pass separator in a module
|
|
containing a non-trivial MODEND. Flat segments are now declared
|
|
using the FLAT attribute. `os2' is no longer a valid object format
|
|
name: use `obj'.
|
|
|
|
\b Removed the fixed-size temporary storage in the evaluator. Very very
|
|
long expressions (like `mov ax,1+1+1+1+...' for two hundred 1s or
|
|
so) should now no longer crash NASM.
|
|
|
|
\b Fixed a bug involving segfaults on disassembly of MMX instructions,
|
|
by changing the meaning of one of the operand-type flags in nasm.h.
|
|
This may cause other apparently unrelated MMX problems; it needs to
|
|
be tested thoroughly.
|
|
|
|
\b Fixed some buffer overrun problems with large OBJ output files.
|
|
Thanks to DJ Delorie for the bug report and fix.
|
|
|
|
\b Made preprocess-only mode actually listen to the \c{%line} markers as it
|
|
prints them, so that it can report errors more sanely.
|
|
|
|
\b Re-designed the evaluator to keep more sensible track of expressions
|
|
involving forward references: can now cope with previously-nightmare
|
|
situations such as:
|
|
|
|
\c mov ax,foo | bar
|
|
\c foo equ 1
|
|
\c bar equ 2
|
|
|
|
\b Added the ALIGN and ALIGNB standard macros.
|
|
|
|
\b Added PIC support in ELF: use of WRT to obtain the four extra
|
|
relocation types needed.
|
|
|
|
\b Added the ability for output file formats to define their own
|
|
extensions to the GLOBAL, COMMON and EXTERN directives.
|
|
|
|
\b Implemented common-variable alignment, and global-symbol type and
|
|
size declarations, in ELF.
|
|
|
|
\b Implemented NEAR and FAR keywords for common variables, plus
|
|
far-common element size specification, in OBJ.
|
|
|
|
\b Added a feature whereby EXTERNs and COMMONs in OBJ can be given a
|
|
default WRT specification (either a segment or a group).
|
|
|
|
\b Transformed the Unix NASM archive into an auto-configuring package.
|
|
|
|
\b Added a sanity-check for people applying SEG to things which are
|
|
already segment bases: this previously went unnoticed by the SEG
|
|
processing and caused OBJ-driver panics later.
|
|
|
|
\b Added the ability, in OBJ format, to deal with `MOV EAX,<segment>'
|
|
type references: OBJ doesn't directly support dword-size segment
|
|
base fixups, but as long as the low two bytes of the constant term
|
|
are zero, a word-size fixup can be generated instead and it will
|
|
work.
|
|
|
|
\b Added the ability to specify sections' alignment requirements in
|
|
Win32 object files and pure binary files.
|
|
|
|
\b Added preprocess-time expression evaluation: the \c{%assign} (and
|
|
\c{%iassign}) directive and the bare \c{%if} (and \c{%elif}) conditional. Added
|
|
relational operators to the evaluator, for use only in \c{%if}
|
|
constructs: the standard relationals = < > <= >= <> (and C-like
|
|
synonyms == and !=) plus low-precedence logical operators &&, ^^ and
|
|
||.
|
|
|
|
\b Added a preprocessor repeat construct: \c{%rep} / \c{%exitrep} / \c{%endrep}.
|
|
|
|
\b Added the __FILE__ and __LINE__ standard macros.
|
|
|
|
\b Added a sanity check for number constants being greater than
|
|
0xFFFFFFFF. The warning can be disabled.
|
|
|
|
\b Added the %0 token whereby a variadic multi-line macro can tell how
|
|
many parameters it's been given in a specific invocation.
|
|
|
|
\b Added \c{%rotate}, allowing multi-line macro parameters to be cycled.
|
|
|
|
\b Added the `*' option for the maximum parameter count on multi-line
|
|
macros, allowing them to take arbitrarily many parameters.
|
|
|
|
\b Added the ability for the user-level forms of EXTERN, GLOBAL and
|
|
COMMON to take more than one argument.
|
|
|
|
\b Added the IMPORT and EXPORT directives in OBJ format, to deal with
|
|
Windows DLLs.
|
|
|
|
\b Added some more preprocessor \c{%if} constructs: \c{%ifidn} / \c{%ifidni} (exact
|
|
textual identity), and \c{%ifid} / \c{%ifnum} / \c{%ifstr} (token type testing).
|
|
|
|
\b Added the ability to distinguish SHL AX,1 (the 8086 version) from
|
|
SHL AX,BYTE 1 (the 286-and-upwards version whose constant happens to
|
|
be 1).
|
|
|
|
\b Added NetBSD/FreeBSD/OpenBSD's variant of a.out format, complete
|
|
with PIC shared library features.
|
|
|
|
\b Changed NASM's idiosyncratic handling of FCLEX, FDISI, FENI, FINIT,
|
|
FSAVE, FSTCW, FSTENV, and FSTSW to bring it into line with the
|
|
otherwise accepted standard. The previous behaviour, though it was a
|
|
deliberate feature, was a deliberate feature based on a
|
|
misunderstanding. Apologies for the inconvenience.
|
|
|
|
\b Improved the flexibility of ABSOLUTE: you can now give it an
|
|
expression rather than being restricted to a constant, and it can
|
|
take relocatable arguments as well.
|
|
|
|
\b Added the ability for a variable to be declared as EXTERN multiple
|
|
times, and the subsequent definitions are just ignored.
|
|
|
|
\b We now allow instruction prefixes (CS, DS, LOCK, REPZ etc) to be
|
|
alone on a line (without a following instruction).
|
|
|
|
\b Improved sanity checks on whether the arguments to EXTERN, GLOBAL
|
|
and COMMON are valid identifiers.
|
|
|
|
\b Added misc/exebin.mac to allow direct generation of .EXE files by
|
|
hacking up an EXE header using DB and DW; also added test/binexe.asm
|
|
to demonstrate the use of this. Thanks to Yann Guidon for
|
|
contributing the EXE header code.
|
|
|
|
\b ndisasm forgot to check whether the input file had been successfully
|
|
opened. Now it does. Doh!
|
|
|
|
\b Added the Cyrix extensions to the MMX instruction set.
|
|
|
|
\b Added a hinting mechanism to allow [EAX+EBX] and [EBX+EAX] to be
|
|
assembled differently. This is important since [ESI+EBP] and
|
|
[EBP+ESI] have different default base segment registers.
|
|
|
|
\b Added support for the PharLap OMF extension for 4096-byte segment
|
|
alignment.
|
|
|
|
|
|
\S{cl-0.95 released July 1997} Version 0.95 released July 1997
|
|
|
|
\b Fixed yet another ELF bug. This one manifested if the user relied on
|
|
the default segment, and attempted to define global symbols without
|
|
first explicitly declaring the target segment.
|
|
|
|
\b Added makefiles (for NASM and the RDF tools) to build Win32 console
|
|
apps under Symantec C++. Donated by Mark Junker.
|
|
|
|
\b Added `macros.bas' and `insns.bas', QBasic versions of the Perl
|
|
scripts that convert `standard.mac' to `macros.c' and convert
|
|
`insns.dat' to `insnsa.c' and `insnsd.c'. Also thanks to Mark
|
|
Junker.
|
|
|
|
\b Changed the diassembled forms of the conditional instructions so
|
|
that JB is now emitted as JC, and other similar changes. Suggested
|
|
list by Ulrich Doewich.
|
|
|
|
\b Added `@' to the list of valid characters to begin an identifier
|
|
with.
|
|
|
|
\b Documentary changes, notably the addition of the `Common Problems'
|
|
section in nasm.doc.
|
|
|
|
\b Fixed a bug relating to 32-bit PC-relative fixups in OBJ.
|
|
|
|
\b Fixed a bug in perm_copy() in labels.c which was causing exceptions
|
|
in cleanup_labels() on some systems.
|
|
|
|
\b Positivity sanity check in TIMES argument changed from a warning to
|
|
an error following a further complaint.
|
|
|
|
\b Changed the acceptable limits on byte and word operands to allow
|
|
things like `~10111001b' to work.
|
|
|
|
\b Fixed a major problem in the preprocessor which caused seg-faults if
|
|
macro definitions contained blank lines or comment-only lines.
|
|
|
|
\b Fixed inadequate error checking on the commas separating the
|
|
arguments to `db', `dw' etc.
|
|
|
|
\b Fixed a crippling bug in the handling of macros with operand counts
|
|
defined with a `+' modifier.
|
|
|
|
\b Fixed a bug whereby object file formats which stored the input file
|
|
name in the output file (such as OBJ and COFF) weren't doing so
|
|
correctly when the output file name was specified on the command
|
|
line.
|
|
|
|
\b Removed [INC] and [INCLUDE] support for good, since they were
|
|
obsolete anyway.
|
|
|
|
\b Fixed a bug in OBJ which caused all fixups to be output in 16-bit
|
|
(old-format) FIXUPP records, rather than putting the 32-bit ones in
|
|
FIXUPP32 (new-format) records.
|
|
|
|
\b Added, tentatively, OS/2 object file support (as a minor variant on
|
|
OBJ).
|
|
|
|
\b Updates to Fox Cutter's Borland C makefile, Makefile.bc2.
|
|
|
|
\b Removed a spurious second fclose() on the output file.
|
|
|
|
\b Added the `-s' command line option to redirect all messages which
|
|
would go to stderr (errors, help text) to stdout instead.
|
|
|
|
\b Added the `-w' command line option to selectively suppress some
|
|
classes of assembly warning messages.
|
|
|
|
\b Added the `-p' pre-include and `-d' pre-define command-line options.
|
|
|
|
\b Added an include file search path: the `-i' command line option.
|
|
|
|
\b Fixed a silly little preprocessor bug whereby starting a line with a
|
|
`%!' environment-variable reference caused an `unknown directive'
|
|
error.
|
|
|
|
\b Added the long-awaited listing file support: the `-l' command line
|
|
option.
|
|
|
|
\b Fixed a problem with OBJ format whereby, in the absence of any
|
|
explicit segment definition, non-global symbols declared in the
|
|
implicit default segment generated spurious EXTDEF records in the
|
|
output.
|
|
|
|
\b Added the NASM environment variable.
|
|
|
|
\b From this version forward, Win32 console-mode binaries will be
|
|
included in the DOS distribution in addition to the 16-bit binaries.
|
|
Added Makefile.vc for this purpose.
|
|
|
|
\b Added `return 0;' to test/objlink.c to prevent compiler warnings.
|
|
|
|
\b Added the __NASM_MAJOR__ and __NASM_MINOR__ standard defines.
|
|
|
|
\b Added an alternative memory-reference syntax in which prefixing an
|
|
operand with `&' is equivalent to enclosing it in square brackets,
|
|
at the request of Fox Cutter.
|
|
|
|
\b Errors in pass two now cause the program to return a non-zero error
|
|
code, which they didn't before.
|
|
|
|
\b Fixed the single-line macro cycle detection, which didn't work at
|
|
all on macros with no parameters (caused an infinite loop). Also
|
|
changed the behaviour of single-line macro cycle detection to work
|
|
like cpp, so that macros like `extrn' as given in the documentation
|
|
can be implemented.
|
|
|
|
\b Fixed the implementation of WRT, which was too restrictive in that
|
|
you couldn't do `mov ax,[di+abc wrt dgroup]' because (di+abc) wasn't
|
|
a relocatable reference.
|
|
|
|
|
|
\S{cl-0.94 released April 1997} Version 0.94 released April 1997
|
|
|
|
|
|
\b Major item: added the macro processor.
|
|
|
|
\b Added undocumented instructions SMI, IBTS, XBTS and LOADALL286. Also
|
|
reorganised CMPXCHG instruction into early-486 and Pentium forms.
|
|
Thanks to Thobias Jones for the information.
|
|
|
|
\b Fixed two more stupid bugs in ELF, which were causing `ld' to
|
|
continue to seg-fault in a lot of non-trivial cases.
|
|
|
|
\b Fixed a seg-fault in the label manager.
|
|
|
|
\b Stopped FBLD and FBSTP from _requiring_ the TWORD keyword, which is
|
|
the only option for BCD loads/stores in any case.
|
|
|
|
\b Ensured FLDCW, FSTCW and FSTSW can cope with the WORD keyword, if
|
|
anyone bothers to provide it. Previously they complained unless no
|
|
keyword at all was present.
|
|
|
|
\b Some forms of FDIV/FDIVR and FSUB/FSUBR were still inverted: a
|
|
vestige of a bug that I thought had been fixed in 0.92. This was
|
|
fixed, hopefully for good this time...
|
|
|
|
\b Another minor phase error (insofar as a phase error can _ever_ be
|
|
minor) fixed, this one occurring in code of the form
|
|
|
|
\c rol ax,forward_reference
|
|
\c forward_reference equ 1
|
|
|
|
\b The number supplied to TIMES is now sanity-checked for positivity,
|
|
and also may be greater than 64K (which previously didn't work on
|
|
16-bit systems).
|
|
|
|
\b Added Watcom C makefiles, and misc/pmw.bat, donated by Dominik Behr.
|
|
|
|
\b Added the INCBIN pseudo-opcode.
|
|
|
|
\b Due to the advent of the preprocessor, the [INCLUDE] and [INC]
|
|
directives have become obsolete. They are still supported in this
|
|
version, with a warning, but won't be in the next.
|
|
|
|
\b Fixed a bug in OBJ format, which caused incorrect object records to
|
|
be output when absolute labels were made global.
|
|
|
|
\b Updates to RDOFF subdirectory, and changes to outrdf.c.
|

\S{cl-0.93 released January 1997} Version 0.93 released January 1997
|
|
|
|
This release went out in a great hurry after semi-crippling bugs
|
|
were found in 0.92.
|
|
|
|
\b Really \e{did} fix the stack overflows this time. *blush*
|
|
|
|
\b Had problems with EA instruction sizes changing between passes, when
|
|
an offset contained a forward reference and so 4 bytes were
|
|
allocated for the offset in pass one; by pass two the symbol had
|
|
been defined and happened to be a small absolute value, so only 1
|
|
byte got allocated, causing instruction size mismatch between passes
|
|
and hence incorrect address calculations. Fixed.
|
|
|
|
\b Stupid bug in the revised ELF section generation fixed (associated
|
|
string-table section for .symtab was hard-coded as 7, even when this
|
|
didn't fit with the real section table). Was causing `ld' to
|
|
seg-fault under Linux.
|
|
|
|
\b Included a new Borland C makefile, Makefile.bc2, donated by Fox
|
|
Cutter <lmb@comtch.iea.com>.
|
|
|
|
|
|
\S{cl-0.92 released January 1997} Version 0.92 released January 1997
|
|
|
|
\b The FDIVP/FDIVRP and FSUBP/FSUBRP pairs had been inverted: this was
|
|
fixed. This also affected the LCC driver.
|
|
|
|
\b Fixed a bug regarding 32-bit effective addresses of the form
|
|
\c{[other_register+ESP]}.
|
|
|
|
\b Documentary changes, notably documentation of the fact that Borland
|
|
Win32 compilers use `obj' rather than `win32' object format.
|
|
|
|
\b Fixed the COMENT record in OBJ files, which was formatted
|
|
incorrectly.
|
|
|
|
\b Fixed a bug causing segfaults in large RDF files.
|
|
|
|
\b OBJ format now strips initial periods from segment and group
|
|
definitions, in order to avoid complications with the local label
|
|
syntax.
|
|
|
|
\b Fixed a bug in disassembling far calls and jumps in NDISASM.
|
|
|
|
\b Added support for user-defined sections in COFF and ELF files.
|
|
|
|
\b Compiled the DOS binaries with a sensible amount of stack, to
|
|
prevent stack overflows on any arithmetic expression containing
|
|
parentheses.
|
|
|
|
\b Fixed a bug in handling of files that do not terminate in a newline.
|
|
|
|
|
|
