Chris Lattner 9535f90abe move the "movsd -> movsl" alias to the .td files,
tidy up the movsx and movzx aliases.

Chris Lattner 8188fb264f fix some bugs in the alias support, unblocking changing of "clr" aliases
from c++ hacks to proper .td InstAlias definitions.  Change them!

Chris Lattner 865dd96f22 use our fancy new MnemonicAlias mechanism to remove a bunch of hacks
from X86AsmParser.cpp

Chris Lattner dd3b09c234 Implement enough of the missing instalias support to get
aliases installed and working.  They now work when the
matched pattern and the result instruction have exactly
the same operand list.

This is now enough for us to define proper aliases for
movzx and movsx, implementing rdar://8017633 and PR7459.

Note that we do not accept instructions like:
  movzx 0(%rsp), %rsi

GAS accepts this instruction, but it doesn't make any
sense because we don't know the size of the memory
operand.  It could be 8/16/32 bits.

Chris Lattner 2cb092dc55 Implement (and document!) support for MnemonicAlias's to have Requires
directives, allowing things like this:

def : MnemonicAlias<"pop", "popl">, Requires<[In32BitMode]>;
def : MnemonicAlias<"pop", "popq">, Requires<[In64BitMode]>;

Move the rest of the X86 MnemonicAliases over to the .td file.

Chris Lattner ba7b4fea97 implement (and document!) the first kind of MC assembler alias, which
just remaps one mnemonic to another.  Convert a few of the X86 aliases
from .cpp to .td code.

Kevin Enderby 9ad2166899 Yet another tweak to X86 instructions to add ud2a as an alias to ud2
(still to add ud2b).

Kevin Enderby 20b021c970 Another tweak to X86 instructions to add the missing flex instruction (without
the wait prefix).

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.

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.

Andrew Trick edd006c1c3 Reverting r117031 to cleanup valgrind errors.
It doesn't look like anything is wrong with the checkin,
but the new test cases expose a mem bug in AsmParser.

Kevin Enderby 49843c0162 Added a few tweaks to the Intel Descriptor-table support instructions to allow
word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes.  This is again for use just with assembly source for llvm-mc .

llvm-svn: 116773
2010-10-19 00:01:44 +00:00
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.

Chris Lattner b44fd24fc1 change the protocol TargetAsmPArser::MatchInstruction method to take an
MCStreamer to emit into instead of an MCInst to fill in.  This allows the
matcher extra flexibility and is more convenient.

Chris Lattner ff0062af62 Fix rdar://8468087 - llvm-mc commutes fmul (and friend) operands.
My previous fix for rdar://8456371 should only apply to fmulp/faddp,
not to fmul/fadd.  Instruction set orthogonality is overrated or 
something.

Chris Lattner bd85725341 Fix an inconsistency in the x86 backend that led it to reject "calll foo" on
x86-32: 32-bit calls were named "call" not "calll".  64-bit calls were correctly
named "callq", so this only impacted x86-32.

This fixes rdar://8456370 - llvm-mc rejects 'calll'

This also exposes that mingw/64 is generating a 32-bit call instead of a 64-bit call,
I will file a bugzilla.
