Add support for the C_SKY series of processors.
This patch series is a new binutils port for C-SKY processors, including support for both the V1 and V2 processor variants. V1 is derived from the MCore architecture while V2 is substantially different, with mixed 16- and 32-bit instructions, a larger register set, a different (but overlapping) ABI, etc. There is support for bare-metal ELF targets and Linux with both glibc and uClibc.
This code is being contributed jointly by C-SKY Microsystems and Mentor Graphics. C-SKY is responsible for the technical content and has proposed Lifang Xia and Yunhai Shang as port maintainers. (Note that C-SKY does have a corporate copyright assignment on file with the FSF.) Mentor Graphics' role has been cleaning up the code, adding documentation and additional test cases, etc, to address issues we anticipated reviewers would complain about.

x86: Add -O[2|s] assembler command-line options
On x86, some instructions have alternate shorter encodings:
1. When the upper 32 bits of destination registers of
andq $imm31, %r64
testq $imm31, %r64
xorq %r64, %r64
subq %r64, %r64
known to be zero, we can encode them without the REX_W bit:
andl $imm31, %r32
testl $imm31, %r32
xorl %r32, %r32
subl %r32, %r32
This optimization is enabled with -O, -O2 and -Os.
2. Since 0xb0 mov with 32-bit destination registers zero-extends 32-bit
immediate to 64-bit destination register, we can use it to encode 64-bit
mov with 32-bit immediates. This optimization is enabled with -O, -O2
and -Os.
3. Since the upper bits of destination registers of VEX128 and EVEX128
instructions are extended to zero, if all bits of destination registers
of AVX256 or AVX512 instructions are zero, we can use VEX128 or EVEX128
encoding to encode AVX256 or AVX512 instructions. When 2 source
registers are identical, AVX256 and AVX512 andn and xor instructions:
VOP %reg, %reg, %dest_reg
can be encoded with
VOP128 %reg, %reg, %dest_reg
This optimization is enabled with -O2 and -Os.
4. 16-bit, 32-bit and 64-bit register tests with immediate may be
encoded as 8-bit register test with immediate. This optimization is
enabled with -Os.
This patch does:
1. Add {nooptimize} pseudo prefix to disable instruction size
optimization.
2. Add optimize to i386_opcode_modifier to tell assembler that encoding
of an instruction may be optimized.

Add .nop assembler directive
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits
SIZE bytes filled with no-op instructions. SIZE is absolute expression.
The optional CONTROL byte controls how no-op instructions should be
generated. If the comma and @var{control} are omitted, CONTROL is
assumed to be zero.
For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size
limit of a single no-op instruction. The valid values of CONTROL byte
are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode,
between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit
is set to the maximum supported size.
2 new relax states, rs_space_nop and rs_fill_nop, are added to enum
_relax_state, which are similar to rs_space and rs_fill, respectively,
but they fill with no-op instructions, instead of a single byte. A
target backend must override the default md_generate_nops to generate
proper no-op instructions. Otherwise, an error of unimplemented .nop
directive will be issued whenever .nop directive is used.

Support ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX
Mark an ALLOC section, which should be placed in special memory area,
with SHF_GNU_MBIND. Its sh_info field indicates the special memory
type. GNU_MBIND section names start with ".mbind" so that they are
placed as orphan sections by linker. All input GNU_MBIND sections
with the same sh_type, sh_flags and sh_info are placed in one output
GNU_MBIND section. In executable and shared object, create a
GNU_MBIND segment for each GNU_MBIND section and its segment type is
PT_GNU_MBIND_LO plus the sh_info value. Each GNU_MBIND segment is
aligned at page boundary.
The assembler syntax:
.section .mbind.foo,"adx",%progbits
^ 0: Special memory type.
|
'd' for SHF_GNU_MBIND.
.section .mbind.foo,"adx",%progbits,0x1

Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

* New command-line option --elf-stt-common= for ELF targets to control
|
Properly implement STT_COMMON
The BFD configure option, --enable-elf-stt-common, can't be to used to
verify STT_COMMON implementation with the normal binutils build. Instead,
this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF
assembler/objcopy and adds -z common/-z nocommon to ld.
A configure option, --enable-elf-stt-common, is added to gas to specify
whether ELF assembler should generate common symbols with the STT_COMMON
type by default.
Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF
common symbols.

Add --enable-compressed-debug-sections={all,gas,gold,ld}
This patch removes the gas configure option:
--enable-compressed-debug-sections
and adds a toplevel configure option:
--enable-compressed-debug-sections={all,gas,gold,ld}
to enable compressed debug sections for gas, gold or ld by default. At
the moment, this configure option is ignored by gold and ld. For x86
Linux targets, default to compressing debug sections in gas.

|
* The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
|
|
|
|
|
|
indicate that if the symbol is the target of a relocation, its value should
|
|
|
|
|
|
not be use. Instead the function should be invoked and its result used as
|
|
|
|
|
|
the value.

2005-10-26 01:42:02 +08:00
|
|
|
|
* Support for the Z80 processor family has been added.
|
|
|
|
|
|
|
2005-10-13 08:57:43 +08:00
|
|
|
|
* Add support for the "@<file>" syntax to the command line, so that extra
|
|
|
|
|
|
switches can be read from <file>.
|
|
|
|
|
|
|
2018-07-02 18:18:24 +08:00
|
|
|
|
* The SH target supports a new command-line switch --enable-reg-prefix which,
|
2005-10-06 19:44:07 +08:00
|
|
|
|
if enabled, will allow register names to be optionally prefixed with a $
|
|
|
|
|
|
character. This allows register names to be distinguished from label names.

|
|
|
|
|
2005-05-06 14:50:31 +08:00
|
|
|
|
* Macros with a variable number of arguments are now supported. See the
|
|
|
|
|
|
documentation for how this works.
|
|
|
|
|
|
|
2005-04-12 16:42:41 +08:00
|
|
|
|
* Added --reduce-memory-overheads switch to reduce the size of the hash
|
|
|
|
|
|
tables used, at the expense of longer assembly times, and
|
|
|
|
|
|
--hash-size=<NUMBER> to set the size of the hash tables used by gas.
|
|
|
|
|
|
|
2005-04-11 20:46:38 +08:00
|
|
|
|
* Macro names and macro parameter names can now be any identifier that would
|
|
|
|
|
|
also be legal as a symbol elsewhere. For macro parameter names, this is
|
|
|
|
|
|
known to cause problems in certain sources when the respective target uses
|
|
|
|
|
|
characters inconsistently, and thus macro parameter references may no longer
|
|
|
|
|
|
be recognized as such (see the documentation for details).

|
|
|
|
|
|
for the VAX target in order to be more compatible with the VAX MACRO
|
|
|
|
|
|
assembler.
|
|
|
|
|
|
|
2018-07-02 18:18:24 +08:00
|
|

|
|
|
|
|
|
2004-11-08 21:17:43 +08:00

2004-05-07 22:44:56 +08:00
|
|
|
|
* Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
|
|
|
|
|
|
on pe[i]-i386; required for this target's DWARF 2 support.
|

Changes in 2.15:
|
|
|
|
|
|
|
2004-04-21 08:44:36 +08:00
|
|
|
|
* The MIPS -membedded-pic option (Embedded-PIC code generation) is
|
|
|
|

|
|
specification has been added to the arm assembler.
|
2003-11-14 16:21:02 +08:00
|
|
|
|
|
* config/tc-arm.texi (struct reg_entry): Add new field 'builtin'.
(rn_table, iwmmxt_table, cp_table, cn_table, fn_table, sn_table,
dn_table, mav_mvf_table, mac_mvd_table, mav_mvfx_table,

2003-11-06 23:30:05 +08:00
|
|
|
|

|
|
|
|
|
|

|
|
|
|
|
|
|
2003-10-21 21:28:59 +08:00

|
|
|
|
|
|
|
2003-06-10 14:46:34 +08:00
|
|
|
|
* Added -n switch for x86 assembler. By default, x86 GAS replaces
|
|
|
|
|
|
multiple nop instructions used for alignment within code sections
|
|
|
|
|
|
with multi-byte nop instructions such as leal 0(%esi,1),%esi. This
|
|
|
|
|
|
switch disables the optimization.
|
|
|
|
|
|
|
2004-01-09 10:34:04 +08:00
|
|
|
|
* Removed -n option from MIPS assembler. It was not useful, and confused the
|
|
|
|
|
|
existing -non_shared option.

|
|
|
|
|
|
uses it (gas/testsuite/gas/all/test-gen.c and test-exmaple.c).

|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* GASP has now been deprecated and will be removed in a future release. Use
|
|
|
|
|
|
the macro facilities in GAS instead.
|
2002-02-22 00:51:00 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* GASP now correctly parses floating point numbers. Unless the base is
|
|
|
|
|
|
explicitly specified, they are interpreted as decimal numbers regardless of
|
|
|
|
|
|
the currently specified base.

2012-03-14 00:59:57 +08:00
|
|
|
|
* The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for
|
|
|
|
|
|
specifying the target instruction set. The old method of specifying the
|
2002-07-19 15:52:40 +08:00
|
|
|
|
target processor has been deprecated, but is still accepted for
|
|
|
|
|
|
compatibility.
|

|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
|
|
|
|
|
|
but still works for compatability.
|
2001-06-30 05:27:43 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|

|
* The MIPS assembler no longer issues a warning by default when it
|
2018-07-02 18:18:24 +08:00
|
|
|
|
generates a nop instruction from a macro. The new command-line option
|
2002-07-19 15:52:40 +08:00

|
|
|
|
* A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
|
2002-07-19 15:52:40 +08:00

|
|
|
2012-03-14 00:59:57 +08:00
|
|
|

* Greatly improved instruction operand checking for i386. This change will
|
2002-07-19 15:52:40 +08:00
|
|
|
|
produce errors or warnings on incorrect assembly code that previous versions
|
|
|
|
|
|
of gas accepted. If you get unexpected messages from code that worked with
|
|
|
|
|
|
older versions of gas, please double check the code before reporting a bug.

2012-03-14 00:59:57 +08:00
|
|
|
|
* The assembler now optimizes the exception frame information generated by egcs
|
2002-07-19 15:52:40 +08:00

|
2002-07-19 15:52:40 +08:00
|
|
|
|
listing.
|
1999-05-03 15:29:11 +08:00

|
|
|
|
* m68k options --base-size-default-16, --base-size-default-32,
|
|
|
|
|
|
--disp-size-default-16, and --disp-size-default-32 added.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* The alignment directives now take an optional third argument, which is the
|
|
|
|
|
|
maximum number of bytes to skip. If doing the alignment would require
|
|
|
|
|
|
skipping more than the given number of bytes, the alignment is not done at
|
|
|
|
|
|
all.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|

|
|
|
|
|
|
conditionals in listings.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
|
|
|
|
|
|
the symbol is already defined.
|
1999-05-03 15:29:11 +08:00

|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* The PowerPC assembler now allows the use of symbolic register names (r0,
|
|
|
|
|
|
etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.)
|
|
|
|
|
|
can be used any time. PowerPC 860 move to/from SPR instructions have been
|
|
|
|
|
|
added.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* PowerPC ELF support added.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the
|
|
|
|
|
|
default is to build COFF-only support. To get a set of tools that generate
|
2012-03-14 00:59:57 +08:00
|
|
|
|
ELF (they'll understand both COFF and ELF), you must configure with
|
2002-07-19 15:52:40 +08:00
|
|
|
|
target=i386-unknown-sco3.2v5elf.
|

|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Gas now directly supports macros, without requiring GASP.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Gas now has an MRI assembler compatibility mode. Use -M or --mri to select
|
|
|
|
|
|
MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the
|
|
|
|
|
|
``.mri 0'' is seen; this can be convenient for inline assembler code.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|

|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Updated VMS support, from Pat Rankin, including considerably improved
|

1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
|
2012-03-14 00:59:57 +08:00
|
|
|
|
provide for possible future gcc changes, for targets where gas provides some
|
|
|
|
|
|
features not available in the native assembler. If the native assembler is
|
2002-07-19 15:52:40 +08:00
|
|
|
|
used, it should become obvious pretty quickly what the problem is.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3
|
2002-07-19 15:52:40 +08:00
|
|
|
|
also, but didn't get into the NEWS file.)
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Weak symbol support for a.out.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* A bug in the listing code which could cause an infinite loop has been fixed.
|
2002-07-19 15:52:40 +08:00
|
|
|
|
Bugs in listings when generating a COFF object file have also been fixed.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00

|
|
|
|
|
|
now. Support for the 21164 has been contributed by Digital.

|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
|

Changes in 2.3:
|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Mach i386 support, by David Mackenzie and Ken Raeburn.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* RS/6000 and PowerPC support by Ian Taylor.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
|
|
|
|
|
|
based on mail received from various people. The `-h#' option should work
|
|
|
|
|
|
again too.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work
|
2012-03-14 00:59:57 +08:00
|
|
|
|
with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special
|
2002-07-19 15:52:40 +08:00
|
|
|
|
version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve
|
|
|
|
|
|
this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
|
|
|
|
|
|
in the "dist" directory.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Vax support in gas fixed for BSD, so it builds and seems to run a couple
|
|
|
|
|
|
simple tests okay. I haven't put it through extensive testing. (GNU make is
|
|
|
|
|
|
currently required for BSD 4.3 builds.)
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is
|
2002-07-19 15:52:40 +08:00
|
|
|
|
based on code donated by CMU, which used an a.out-based format. I'm afraid
|
|
|
|
|
|
the alpha-a.out support is pretty badly mangled, and much of it removed;
|
|
|
|
|
|
making it work will require rewriting it as BFD support for the format anyways.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Irix 5 support.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* The test suites have been fixed up a bit, so that they should work with a
|
2002-07-19 15:52:40 +08:00
|
|
|
|
couple different versions of expect and dejagnu.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* Symbols' values are now handled internally as expressions, permitting more
|
|
|
|
|
|
flexibility in evaluating them in some cases. Some details of relocation
|
2002-07-19 15:52:40 +08:00
|
|
|
|
handling have also changed, and simple constant pool management has been
|
|
|
|
|
|
added, to make the Alpha port easier.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* New option "--statistics" for printing out program run times. This is
|
|
|
|
|
|
intended to be used with the gcc "-Q" option, which prints out times spent in
|
|
|
|
|
|
various phases of compilation. (You should be able to get all of them
|
|
|
|
|
|
printed out with "gcc -Q -Wa,--statistics", I think.)
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
|
Changes in 2.2:
|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* RS/6000 AIX and MIPS SGI Irix 5 support has been added.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* Configurations that are still in development (and therefore are convenient to
|
|
|
|
|
|
have listed in configure.in) still get rejected without a minor change to
|
2002-07-19 15:52:40 +08:00
|
|
|
|
gas/Makefile.in, so people not doing development work shouldn't get the
|
|
|
|
|
|
impression that support for such configurations is actually believed to be
|
|
|
|
|
|
reliable.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* The program name (usually "as") is printed when a fatal error message is
|
2002-07-19 15:52:40 +08:00
|
|
|
|
displayed. This should prevent some confusion about the source of occasional
|
|
|
|
|
|
messages about "internal errors".
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* ELF support is falling into place. Support for the 386 should be working.
|
2002-07-19 15:52:40 +08:00
|
|
|
|
Support for SPARC Solaris is in. HPPA support from Utah is being integrated.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Symbol values are maintained as expressions instead of being immediately
|
|
|
|
|
|
boiled down to add-symbol, sub-symbol, and constant. This permits slightly
|
|
|
|
|
|
more complex calculations involving symbols whose values are not alreadey
|
|
|
|
|
|
known.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* DBX-style debugging info ("stabs") is now supported for COFF formats.
|
2012-03-14 00:59:57 +08:00
|
|
|
|
If any stabs directives are seen in the source, GAS will create two new
|
|
|
|
|
|
sections: a ".stab" and a ".stabstr" section. The format of the .stab
|
2002-07-19 15:52:40 +08:00
|
|
|
|
section is nearly identical to the a.out symbol format, and .stabstr is
|
|
|
|
|
|
its string table. For this to be useful, you must have configured GCC
|
|
|
|
|
|
to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
|
|
|
|
|
|
that can use the stab sections (4.11 or later).
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS
|
2002-07-19 15:52:40 +08:00
|
|
|
|
support is in progress.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
|
Changes in 2.1:
|
|
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
|
2002-07-19 15:52:40 +08:00
|
|
|
|
incorporated, but not well tested yet.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2012-03-14 00:59:57 +08:00
|
|
|
|
* Altered the opcode table split for m68k; it should require less VM to compile
|
2002-07-19 15:52:40 +08:00
|
|
|
|
with gcc now.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Some minor adjustments to add (Convergent Technologies') Miniframe support,
|
|
|
|
|
|
suggested by Ronald Cole.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* HPPA support (running OSF only, not HPUX) has been contributed by Utah. This
|
|
|
|
|
|
includes improved ELF support, which I've started adapting for SPARC Solaris
|
|
|
|
|
|
2.x. Integration isn't completely, so it probably won't work.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* HP9000/300 support, donated by HP, has been merged in.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Better error messages for unsupported configurations (e.g., hppa-hpux).
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Test suite framework is starting to become reasonable.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|

Changes in 2.0:
|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Mostly bug fixes.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Some more merging of BFD and ELF code, but ELF still doesn't work.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
|
Changes in 1.94:
|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* BFD merge is partly done. Adventurous souls may try giving configure the
|
|
|
|
|
|
"--with-bfd-assembler" option. Currently, ELF format requires it, a.out
|
|
|
|
|
|
format accepts it; SPARC CPU accepts it. It's the default only for OS "elf"
|
|
|
|
|
|
or "solaris". (ELF isn't really supported yet. It needs work. I've got
|
|
|
|
|
|
some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
|
|
|
|
|
|
fully merged yet.)
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* The 68K opcode table has been split in half. It should now compile under gcc
|
|
|
|
|
|
without consuming ridiculous amounts of memory.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* A couple data structures have been reduced in size. This should result in
|
|
|
|
|
|
saving a little bit of space at runtime.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF
|
|
|
|
|
|
code provided ROSE format support, which I haven't merged in yet. (I can
|
|
|
|
|
|
make it available, if anyone wants to try it out.) Ralph's code, for BSD
|
|
|
|
|
|
4.4, supports a.out format. We don't have ECOFF support in just yet; it's
|
|
|
|
|
|
coming.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Support for the Hitachi H8/500 has been added.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* VMS host and target support should be working now, thanks chiefly to Eric
|
|
|
|
|
|
Youngdale.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
|
|
|
|
|
Changes in 1.93.01:
|
|
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* For m68k, support for more processors has been added: 68040, CPU32, 68851.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* For i386, .align is now power-of-two; was number-of-bytes.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* For m68k, "%" is now accepted before register names. For COFF format, which
|
|
|
|
|
|
doesn't use underscore prefixes for C labels, it is required, so variable "a0"
|
|
|
|
|
|
can be distinguished from the register.
|
1999-05-03 15:29:11 +08:00
|
|
|
|
|
2002-07-19 15:52:40 +08:00
|
|
|
|
* Last public release was 1.38. Lots of configuration changes since then, lots
|
|
|
|
|
|
of new CPUs and formats, lots of bugs fixed.
