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 676c61db0e update a bunch of code to use the MachinePointerInfo version of getStore.

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

 2010-09-21 17:42:31 +00:00
Chris Lattner 3d178ed4d4 propagate MachinePointerInfo through various uses of the old 
SelectionDAG::getExtLoad overload, and eliminate it.

Chris Lattner 7727d05dbb convert the targets off the non-MachinePointerInfo of getLoad.

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.

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.

Dan Gohman 3439629239 Reapply r107655 with fixes; insert the pseudo instruction into 
the block before calling the expansion hook. And don't
put EFLAGS in a mbb's live-in list twice.

Dale Johannesen ce97d55ad9 The hasMemory argument is irrelevant to how the argument 
for an "i" constraint should get lowered; PR 6309.  While
this argument was passed around a lot, this is the only
place it was used, so it goes away from a lot of other
places.

changes before doing phi lowering for switches.

Evan Cheng 4158a0ff6b Implement -disable-non-leaf-fp-elim which disable frame pointer elimination 
optimization for non-leaf functions. This will be hooked up to gcc's
-momit-leaf-frame-pointer option. rdar://7886181

Dan Gohman 57c732b032 Add more const qualifiers on TargetMachine and friends. 
llvm-svn: 101977
 2010-04-21 01:34:56 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

Evan Cheng ebe47c872f Avoid using f64 to lower memcpy from constant string. It's cheaper to use i32 store of immediates.

Mon P Wang c576ee9040 Reapply address space patch after fixing an issue in MemCopyOptimizer. 
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset,
e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1)

Evan Cheng 4c014c892a - Avoid using floating point stores to implement memset unless the value is zero. 
- Do not try to infer GV alignment unless its type is sized. It's not possible to infer alignment if it has opaque type.

 2010-04-01 18:19:11 +00:00
Evan Cheng 43cd9e3845 Fix sdisel memcpy, memset, memmove lowering: 
1. Makes it possible to lower with floating point loads and stores.
2. Avoid unaligned loads / stores unless it's fast.
3. Fix some memcpy lowering logic bug related to when to optimize a
   load from constant string into a constant.
4. Adjust x86 memcpy lowering threshold to make it more sane.
5. Fix x86 target hook so it uses vector and floating point memory
   ops more effectively.

Bill Wendling dd3fe94336 The same situation that effected ARM effects PPC with regards to placing the 
LSDA into the TEXT section. We need to generate non-lazy pointers to it on
Mach-O. However, the object the NLP points to may be local to the translation
unit. If so, then the NLP needs to have the value of that object specified
instead of "0", which the linker interprets as "external".

Dale Johannesen 90eab67320 The address of an indirect call must be in R12 on Darwin. 
Make it so.  (This patch is in LowerCall_Darwin, which seems
to be used by SVR4 code as well; since that doesn't belong here,
I haven't worried about this case.)
