cf70f2c2a0 Use -enable-ppc-regscavenger flag for these checks 
llvm-svn: 47916

8d64999daf This is the initial check-in for adding register scavenging to PPC. (Currently, 
PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that
it uses a register other than the default R0 register (the scavenger scrounges
for one). A significant part of this patch fixes how kill information is
handled.

5d96a06b0b Don't hard-code the mask size to be 32, which is incorrect on ppc64 
and was causing aborts with the new APInt changes. This may also be
fixing an obscure ppc64 bug.

febc7ea9bf Fix a latent bug exposed by my truncstore patch. We compiled stfiwx-2.ll to: 
_test:
	fctiwz f0, f1
	stfiwx f0, 0, r4
	blr 

instead of:

_test:
	fctiwz f0, f1
	stfd f0, -8(r1)
	nop
	nop
	lwz r2, -4(r1)
	stb r2, 0(r4)
	blr 

The former is not correct (stores 4 bytes, not 1).

cafc567fb7 Finally implement correct ordered comparisons for PPC, even though 
the code generated is not wonderful.  This turns a miscompilation into
a code quality bug (noted in the ppc readme).  This fixes PR642, which
is over 2 years old (!).  Nate, please review this.

e93a775a4d Fix a significant code quality regression I introduced on PPC64 quite 
a while ago.  We now produce:

_foo:
	mflr r0
	std r0, 16(r1)
	ld r2, 16(r1)
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

instead of:

_foo:
	mflr r0
	std r0, 16(r1)
	lis r0, 0
	ori r0, r0, 16
	ldx r2, r1, r0
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

for:

void foo(void **X) {
  *X = __builtin_return_address(0);
}

on ppc64.

8d329ff809 - Remove the hacky code that forces a memcpy. Alignment is taken care of in the 
FE.
- Explicitly pass in the alignment of the load & store.
- XFAIL 2007-10-23-UnalignedMemcpy.ll because llc has a bug that crashes on
  unaligned pointers.

00e56b0e81 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. 
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.
