0c648204e2 openwcom.mak: wmake uses & for continuation, not \ (sigh) 
wmake uses & for continuation, since \ is used for pathname
separators.

a4835d466c Avoid #including .c files; instead compile as separate units 
Don't #include .c files, even if they are auto-generated; instead
compile them as separate compilation units and let the linker do its
job.

73252a92ae PTEST is SSE4.1; although AMD says it's SSE5. 
Fix this when we have proper support for feature sets, or forget about
the concept entirely.

b726b04813 insns.pl: don't require whitespace before / or \

slash or backslash begins a new operator.

70a13f5a37 insns.pl: support operands that serve double duty 
Sometimes assembly syntax wants to permit a single operand to serve
multiple functions; allow this.

The disassembler could really use to be smarter about those.

1e5203872d insns.dat: make even wider to make space for AVX 
The AVX instructions take more space, so add a few tab stops across
the entire file.

8597e6900c insns.dat: use compiler-generated bytecodes for AVX 
Use compiler-generated bytecodes for the AVX instruction demos.  This
should make it a lot easier for other people (HINT, HINT) to add the
instruction table.

fff5a47e65 Same some space by introducing shorthand byte codes for SSE prefixes 
Properly done, all SSE instructions which has the 66/F2/F3 opcode
multiplex need two prefixes: one to control the use of OSP and one to
control the use of REP.  However, it's a four-way select: np/66/F2/F3;
so introduce shorthand bytecodes for that purpose.

2c94c44f35 Make insnsb.c an actual compilation unit 
"make alldeps" doesn't really like it when included files end in *.c.
Instead of renaming insnsb.c to insnsb.h, make it an actual
compilation unit, since there really isn't any reason for it not to
be.

0a4d23219e insnsb.c: use 5 digits for index, not 4

ff3b57c253 Make MAX_OPERANDS a parameter in insns.pl as well 
MAX_OPERANDS is present in insns.pl as well (although proper C
compilers shouldn't need this kind of zero padding.)  Make sure it's
clear to everyone.

aaa088fbf3 Remove special hacks to avoid zero bytecodes 
We can now have zero bytecodes with impunity, so remove any special
hacks we had to avoid zeroes in the bytecode.

3720f7beae Generate a byte array instead of using strings for the byte codes 
Generate a byte array instead of using C compiler strings for the byte
codes.  This has a few advantages:

- No need to special-case zero due to broken C compilers.
- Only insns.pl only ever reads the string, so we can invent our own
  syntax.
- Compaction.
- We can give it the proper, unsigned type.

bits and an arbitrary fixed value in the bottom four bits.

7334e3ac23 Initial NDISASM support for AVX instructions/VEX prefixes 
Initial NDISASM support for AVX instructions and VEX prefixes.  It
doesn't mean it's correct, but it seems to match my current
understanding.  It can disassemble *some*, but not *all*, of the AVX
test cases (which are known to be at least partially incorrect...)

4d2c38ce75 The AVX R,X,B, and V fields (but not W) are inverted. 
The AVX test cases are still not generated correctly, though.

d85d250fa2 First cut at AVX machinery. 
First cut at AVX machinery support.  The only instruction implemented
is VPERMIL2PS, and it's probably buggy.  I'm checking this in with the
hope that other people can start helping out with (a) testing this,
and (b) adding instructions.

NDISASM support is not there yet.

7117e80702 Initial support for YMM (AVX) registers

No support yet for "yword" or "dy".

7d4d2c3cc9 Avoid some warnings in rdoff/rdf2bin.c 
I received some warnings when running make on the head revision of
nasm from git:

----
rdf2bin.c: In function 'main':
rdf2bin.c:122: warning: comparison between signed and unsigned
rdf2bin.c:123: warning: comparison between signed and unsigned
rdf2bin.c:124: warning: comparison between signed and unsigned
----

I think these warnings are innocuous and should be safely avoidable
with simple casts (please see attached patch).

* rdoff/rdf2bin.c
(main): cast to size_t for comparison with fwrite return value

72ec0e4144 Temporaries in macros need a unique prefix; WSAA*() macros to header 
When using temporaries in macros, given them a unique prefix to avoid
namespace collisions when using one macro inside another.

Move the WSAA*() macros from outelf32/outelf64 to a separate header
file.
