Chris Lattner 2f9f63af0b lower PPC::MFCRpseud when transforming to MC, avoiding calling 
the aborting printSpecial() method.  This gets us to 8 failures.

Chris Lattner 7a5c57ecf4 Implement support for printing register and immediate operands, 
add support for darwin vs aix syntax.  We now can print instructions
like this:

	add r3, r3, r4
	blr 

and (in aix mode):
	add 3, 3, 4
	blr

Duncan Sands 71049f78ed In the calling convention logic, ValVT is always a legal type, 
and as such can be represented by an MVT - the more complicated
EVT is not needed.  Use MVT for ValVT everywhere.

Duncan Sands f5dda01f33 Inside the calling convention logic LocVT is always a simple 
value type, so there is no point in passing it around using
an EVT.  Use the simpler MVT everywhere.  Rather than trying
to propagate this information maximally in all the code that
using the calling convention stuff, I chose to do a mainly
low impact change instead.

Duncan Sands ee4eb2bad1 Remove some variables that are never really used 
(gcc-4.6 warns about these).

Jakob Stoklund Olesen 6c4353ecee PowerPC varargs functions store live-in registers on the stack. Make sure we use 
virtual registers for those stores since RegAllocFast requires that each live
physreg only be used once.

This fixes PR8357.

Chris Lattner d10babfd65 fix the expansion of va_arg instruction on PPC to know the arg 
alignment for PPC32/64, avoiding some masking operations.

llvm-gcc expands vaarg inline instead of using the instruction
so it has never hit this.

Chris Lattner 0e023ea02a fix a long standing wart: all the ComplexPattern's were being 
passed the root of the match, even though only a few patterns
actually needed this (one in X86, several in ARM [which should
be refactored anyway], and some in CellSPU that I don't feel 
like detangling).   Instead of requiring all ComplexPatterns to
take the dead root, have targets opt into getting the root by
putting SDNPWantRoot on the ComplexPattern.

Chris Lattner 6963c1f789 eliminate an old SelectionDAG::getTruncStore method, propagating 
MachinePointerInfo around more.

Chris Lattner 3d178ed4d4 propagate MachinePointerInfo through various uses of the old 
SelectionDAG::getExtLoad overload, and eliminate it.

Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo 
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

Evan Cheng bf4070756f Teach if-converter to be more careful with predicating instructions that would 
take multiple cycles to decode.
For the current if-converter clients (actually only ARM), the instructions that
are predicated on false are not nops. They would still take machine cycles to
decode. Micro-coded instructions such as LDM / STM can potentially take multiple
cycles to decode. If-converter should take treat them as non-micro-coded
simple instructions.

Owen Anderson 755aceb5d0 Don't use PassInfo* as a type identifier for passes. Instead, use the address of the static 
ID member as the sole unique type identifier.  Clean up APIs related to this change.

Torok Edwin 31e90d2dd1 Use indirect calls in PowerPC JIT. 
See PR5201. There is no way to know if direct calls will be within the allowed
range for BL. Hence emit all calls as indirect when in JIT mode.
Without this long-running applications will fail to JIT on PowerPC with a
relocation failure.

Dale Johannesen cf0287e56d PPC doesn't supported VLA with large alignment. This was 
formerly rejected by the FE, so asserted in the BE; now the FE only
warns, so we treat it as a legitimate fatal error in PPC BE.
This means the test for the feature won't pass, so it's xfail'd.

Chris Lattner 749ca32da1 eliminate the TargetInstrInfo::GetInstSizeInBytes hook. 
ARM/PPC/MSP430-specific code (which are the only targets that
implement the hook) can directly reference their target-specific
instrinfo classes.

Bill Wendling 499f797cdd Rename DBG_LABEL PROLOG_LABEL, because it's only used during prolog emission and 
thus is a much more meaningful name.

Jakob Stoklund Olesen 6353e534ec Teach PPCInstrInfo::storeRegToStackSlot and loadRegFromStackSlot to add memory 
operands.

Hopefully this fixes the llvm-gcc-powerpc-darwin9 buildbot. It really shouldn't
since missing memoperands should not affect correctness.
