[2121]: Mark gen_x86_insn.py outputs as generated.
[2122]: Don't read past end of string in parsers (not bug).
[2123]: Fix expression simplification bug.
[2124]: Warn if unused groups are detected in gen_x86_insn.py.
[2125]: VPBLENDVB doesn't have a 256-bit form; remove it.
[2126]: Generate GOTPCREL relocation for [rel foo wrt ..gotpc].
[2127]: Optimize non-strict push with 66 override to byte size if possible.

syntax.
Previously, the forms of push that did this optimization were disabled in
NASM syntax due to conflicting with the size=BITS case. Fix this via
reordering to allow these forms to be active in NASM syntax.

This was because the re2c-generated code always reads the next character
prior to user code being executed. Instead, check for the \0 marker prior
to entering the re2c code. Retain the re2c check just for sanity.

They still need to be separately listed as CLEANFILES as they're built
at make time.

We were printing the previous bytecode's start rather than the label's
bytecode. Use yasm_bc_next_offset() to get the correct offset.

These allow arbitrary prefixes and/or suffixes to be added to
externally-visible (GLOBAL, EXTERN, or COMMON) symbol names.

The way PIC relocations are generated for macho64 requires a bit of a hack
to detect MOV opcodes and generate GOT_LOAD relocs.
GAS contains a similar hack.

Not default nor even distributed in the .tar.gz, the cmake build allows for
loadable yasm plugins by building libyasm as a shared library.
Example plugins are in the plugins/ directory, and may be loaded into a
cmake-built yasm using the -N command line option (non-cmake builds will
not have this option).
Tested only on Linux so far, but should be relatively painless to port to
Windows thanks to the use of cmake rather than libtool to create shared
libraries.
The only modification to the main source tree is some conditional-compiled
additions to yasm.c.

Standard macro sets are looked up based on parser and preprocessor keyword
from individual modules.
The "standard" NASM parser macros now reside in the NASM parser, so when
the GAS parser is used with the NASM preprocessor, the NASM-specific macros
are no longer defined.
Object-format specific macros are now individually defined by each object
formatm module. This allows for the object formats to be independent of the
NASM preprocessor module and yields a small optimization benefit as unused
object format macros don't need to be skipped over.
Also add GAS macro equivalents for the Win64 SEH more complex directives [1].

The FMA instructions swap VEX.vvvv and imm8[7:4] as compared to other AVX
instructions.
Reported by: nasm64developer@users.sf.net
svn path=/trunk/yasm/; revision=2071
A full testcase for NASM mode based on the AVX programming reference is
included. GAS mode should work, but is untested at present.
V-prefix aliases are present for all supported instructions to allow easy
use of the VEX prefix version without significant code modifications.
All comparison and other pseudo-ops are included.

and into a new misc_flags field. This doesn't take any more space,
simplifies the code, and allows adding additional conditions like this in
the future.
Found and fixed a bug in CPU field generation (not copying a set variable
in gen_x86_insn.py).

Fix up condition code naming and add aliases to match SSE5 added to GNU
binutils as follows:
COMcc:
- swapped uneq, unlt, and unle with neq, nlt, and nle
- added unge, ungt, ne, uge, ugt, nge, ngt, une, ge, and gt aliases
PCOMcc:
- added ne alias (for neq)
svn path=/trunk/yasm/; revision=2049
There are 16 condition codes for COM and 8 condition codes for PCOM/PCOMU.

Add testcase for this.
Also fix $-prefixed labels to match non-$-prefixed label behavior
(this has been broken for a very long time).
