Evan Cheng 0165e25564 Disable most of the ARM vfp / NEON MC tests. These are too fragile to be useful. 
I'll work with Jim, Owen, and Bill on an alternative testing strategy until
the assembly parser is available.

 2010-10-27 16:04:30 +00:00
Rafael Espindola eb0c2c170d Add support for the .symver directive. This is really ugly, but most of it is 
contained in the ELF object writer.

llvm-svn: 117448
 2010-10-27 15:18:17 +00:00
Kevin Enderby 9ad2166899 Yet another tweak to X86 instructions to add ud2a as an alias to ud2 
(still to add ud2b).

llvm-svn: 117435
 2010-10-27 03:01:02 +00:00
Kevin Enderby 20b021c970 Another tweak to X86 instructions to add the missing flex instruction (without 
the wait prefix).

llvm-svn: 117434
 2010-10-27 02:53:04 +00:00
Kevin Enderby a1917c7555 Tweaks to X86 instructions to allow the 'w' suffix in places it makes 
sense, when the instruction takes the 16-bit ax register or m16 memory
location.  These changes to llvm-mc matches what the darwin assembler
allows for these instructions.  Done differently than in r117031 that
caused a valgrind error which was later reverted.

llvm-svn: 117433
 2010-10-27 02:32:19 +00:00
Kevin Enderby ba985d9dd5 Added some aliases to the fcomip and fucompi Intel instructions. So that llvm-mc 
will accept versions that the darwin assembler allows.  Forms ending in "pi" and
forms without all the operands.

 2010-10-26 17:40:54 +00:00
Rafael Espindola e8ae98817a Implement some relaxations for arithmetic instructions. The limitation 
on RIP relative relocations looks artificial, but this is a superset of
what we were able to do before.

llvm-svn: 117364
 2010-10-26 14:09:12 +00:00
Bob Wilson e1961fe289 When the "true" and "false" blocks of a diamond if-conversion are the same, 
do not double-count the duplicate instructions by counting once from the
beginning and again from the end.  Keep track of where the duplicates from
the beginning ended and don't go past that point when counting duplicates
at the end.  Radar 8589805.

This change causes one of the MC/ARM/simple-fp-encoding tests to produce
different (better!) code without the vmovne instruction being tested.
I changed the test to produce vmovne and vmoveq instructions but moving
between register files in the opposite direction.  That's not quite the same
but predicated versions of those instructions weren't being tested before,
so at least the test coverage is not any worse, just different.

Jason W Kim e8b3711ae9 Fixing r116753 r116756 r116777 
The failures in r116753 r116756 were caused by a python issue -
Python likes to append 'L' suffix to stringified numbers if the number
is larger than a machine int. Unfortunately, this causes a divergence of
behavior between 32 and 64 bit python versions.

I re-crafted elf-dump/common_dump to take care of these issues by:

1. always printing 0x (makes for easy sed/regex)
2. always print fixed length (exactly 2 + numBits/4 digits long)
   by mod ((2^numBits) - 1)
3. left-padded with '0'

There is a residual common routine that is also used by
macho-dump (dataToHex) , so I left the 'section_data' test values alone.

Kevin Enderby b9783dd9bc Added a handful of x86-32 instructions that were missing so that llvm-mc would 
be more complete.  These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files.  Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added.  Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records.  More missing instructions will be coming.

Bob Wilson 59351844e1 ARM instructions that are both predicated and set the condition codes 
have been printed with the "S" modifier after the predicate.  With ARM's
unified syntax, they are supposed to go in the other order.  We fixed this
for Thumb when we switched to unified syntax but missed changing it for
ARM.  Apparently we don't generate these instructions often because no one
noticed until now.  Thanks to Bill Wendling for the testcase!

Bill Wendling 6f52f8a87d Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on 
here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.
