Remove the MachineMove class.2013-05-13T01:16:13ZRafael Espindolarafael.espindola@gmail.com2013-05-13T01:16:13Zurn:sha1:4a971705bc6030dc2e4338b3cd5cffa2e0f88b7b
It was just a less powerful and more confusing version of
MCCFIInstruction. A side effect is that, since MCCFIInstruction uses
dwarf register numbers, calls to getDwarfRegNum are pushed out, which
should allow further simplifications.
I left the MachineModuleInfo::addFrameMove interface unchanged since
this patch was already fairly big.

Change getFrameMoves to return a const reference.2013-05-11T02:38:11ZRafael Espindolarafael.espindola@gmail.com2013-05-11T02:38:11Zurn:sha1:d84ccfaf50c7843f31ffc74a8a8e33f779453d6e
To add a frame now there is a dedicated addFrameMove which also takes
care of constructing the move itself.

[ms-inline asm] Fix a crasher when we fail on a direct match.2013-05-10T18:24:17ZChad Rosiermcrosier@apple.com2013-05-10T18:24:17Zurn:sha1:ffc49cbea41c08132587a3e622bb65191fa576a2
The issue was that the MatchingInlineAsm and VariantID args to the
MatchInstructionImpl function weren't being set properly. Specifically, when
parsing intel syntax, the parser thought it was parsing inline assembly in the
at&t dialect; that will never be the case.
The crash was caused when the emitter tried to emit the instruction, but the
operands weren't set. When parsing inline assembly we only set the opcode, not
the operands, which is used to lookup the instruction descriptor.

Also, this commit reverts r176036. Now that we're correctly parsing the intel
syntax the pushad/popad don't match properly. I've reimplemented that fix using
a MnemonicAlias.

Generate a compact unwind encoding in the face of a stack alignment push.2013-05-09T20:10:38ZBill Wendlingisanbard@gmail.com2013-05-09T20:10:38Zurn:sha1:edfef3bd27d6269d473fbc570e8c2be02b4070df
We generate a `push' of a random register (%rax) if the stack needs to be
aligned by the size of that register. However, this could mess up compact unwind
generation. In particular, we want to still generate compact unwind in the
presence of this monstrosity.
Check if the push of of the %rax/%eax register. If it is and it's marked with
the `FrameSetup' flag, then we can generate a compact unwind encoding for the
function only if the push is the last FrameSetup instruction.

Simplify the code a bit.2013-05-09T18:21:45ZBill Wendlingisanbard@gmail.com2013-05-09T18:21:45Zurn:sha1:1f4b796b49d13075531ed43b35824ecc9d757467
The compact unwind registers were defined in two different
places. It's better just to place them in the function that uses them
and specify that this is a 64-bit or 32-bit machine.
No functionality change.
