ea043ef039 nasmdoc: document the __float*__ operators 2007-09-24 12:44:38 -07:00
H. Peter Anvin
dc467ba8af Support __float*__ for floating-point numbers in expressions 
Add special operators to allow the use of floating-point constants in
contexts other than DW/DD/DQ/DT/DO.

As part of this checkin, make MAX_KEYWORD generated by tokhash.pl,
since it knows what all the keywords are so it can tell which one is
the longest.

fc565dd362 Implement INVLPGA according to the documentation 
INVLPGA is defined as taking rax,ecx but "the portion of rax used to
form the address is determined by the effective address size", so it
is really ax/eax/rax.

c5b9ce0a84 Auto-generate 0x67 prefixes without the need for \30x codes 
Auto-generate 0x67 prefixes without the need for \30x codes; the
prefix is automatically added when there is a memory operand with
address size differing from the current address size (and impossible
combinations checked for.)

better way to specify to the disassembler exactly how it wants
instructions interpreted.

441ad9d9b2 nasm.spec.in: minor fixes

7b45fbb127 release script: handle stricter CLI parsing for "git tag" 
The current version of "git tag" seems to demand that the options
precede arguments; the name is an argument, but the -m option and its
parameter is an option.

9b8f0ad113 Update nasm.spec.in and make it handle rc releases

releases by using the "mangled" version of the name (1.99.99.91
instead of 2.0rc1).

b10f3e2dca version.pl: support version numbers of the form X.Y[.Z]rcW 
Support version numbers of the form X.Y[.Z]rcW where X, Y, Z and W are
numbers.  For the numeric macros, drop them down to a lower level, so
2.0rc1 is treated as version 1.99.99.91.

bf9a24f464 Slightly optimize the interface to nasm_token_hash() 
Instead of returning -1 from nasm_token_hash, set tv->t_type to
TOKEN_ID and return TOKEN_ID, since that's what stdscan.c wants to do
with it anyway.  This allows us to simply tailcall nasm_token_hash().

fe2177fe42 Support C99-style hexadecimal floating point.

0x <hexadecimal mantissa> p <binary exponent>.  0x1.0e+1 thus is the
same as 2.0.

e31747e95b Unify all standard IEEE floating-point formats; add 128-bit 
Unify all the standard IEEE formats into one function, add support for
IEEE standard 128-bit floating point numbers.

The 80-bit format is still special since it explicitly represents the
integer portion.

eef59fc328 Add NOP with argument to the instruction list 
0F 1F /0 is documented as an EA-taking NOP since the P6.
0F 18..1F + EA are all "hinting nops" (instructions which, when
unimplemented, have no effect rather than #UD) but 0F 1F /0
specifically has no operation whatsoever.
