llvm-svn: 48062
 2008-03-09 00:32:10 +00:00
Dan Gohman d2ab5fd713 Add support for calls with i128 return values on ppc64.

 2008-03-08 00:19:12 +00:00
Dan Gohman 8d2ead2e34 Add support for lowering 128-bit shifts on ppc64. 
llvm-svn: 48029
 2008-03-07 20:36:53 +00:00
Bill Wendling 92e52c636f Add testcase. 
llvm-svn: 48005
 2008-03-06 23:34:22 +00:00
Evan Cheng 29b502e0e0 Fix a coalescer bug wrt how dead copy interval is shortened. 
llvm-svn: 47966
 2008-03-05 22:09:42 +00:00
Bill Wendling 09de8e494e Use -enable-ppc-regscavenger flag for these checks 
llvm-svn: 47916
 2008-03-04 23:16:26 +00:00
Bill Wendling 632ea65072 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.

 2008-03-03 22:19:16 +00:00
Chris Lattner bd0bb3f07f Evan implemented this. 
llvm-svn: 47827
 2008-03-02 17:56:29 +00:00
Dale Johannesen 820de906b1 New test for misaligned Altivec laod/store. 
llvm-svn: 47698
 2008-02-27 23:14:50 +00:00
Dan Gohman 26854f242e 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.

 2008-02-27 21:12:32 +00:00
Bill Wendling 30075852ef Upgrade testcase. 
llvm-svn: 47644
 2008-02-26 23:22:40 +00:00
Gabor Greif 3d9755f6ca Really feed llvm-as with the testcase, do not let it read from stdin. This fixes the hangs seen on solaris10. 
llvm-svn: 47604
 2008-02-26 13:37:13 +00:00
Tanya Lattner a99d8b5a9a Remove llvm-upgrade and update tests. 
llvm-svn: 47325
 2008-02-19 08:07:33 +00:00
Nate Begeman fe61967361 Add testcase for recent legalizer change 
llvm-svn: 47049
 2008-02-13 06:48:40 +00:00
Evan Cheng ad4d57a2f5 Determine whether a spill kills the register it's spilling before insertion rather than trying to undo the kill marker afterwards. 
llvm-svn: 46953
 2008-02-11 08:30:52 +00:00
Evan Cheng 8d78b0597b If a vr is already marked alive in a bb, then it has PHI uses that are visited earlier, then it is not killed in the def block (i.e. not dead). 
llvm-svn: 46763
 2008-02-05 20:04:18 +00:00
Chris Lattner f4e5e556fd Add target triples to these so they don't fail on linux. 
llvm-svn: 46496
 2008-01-29 06:26:07 +00:00
Bill Wendling a60c61dc1a Need to convert to LLVM code and not C. 
llvm-svn: 46397
 2008-01-26 06:56:08 +00:00
Bill Wendling 0b973210f8 Rename the .c to .ll 
llvm-svn: 46396
 2008-01-26 06:53:40 +00:00
Bill Wendling 0f69974fdb Move testcase to the code gen directory.

Dale Johannesen 5c94cb3596 Implement flt_rounds for PowerPC. 
llvm-svn: 46174
 2008-01-18 19:55:37 +00:00
Chris Lattner f5b46f7dad 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).

Chris Lattner aebbe4700a add testcase for regression 
llvm-svn: 46073
 2008-01-16 18:03:52 +00:00
Chris Lattner b17db3afa8 remove darwin/i386 t-t 
llvm-svn: 45743
 2008-01-08 06:52:51 +00:00
Chris Lattner 89f36e6b21 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.

llvm-svn: 45742
 2008-01-08 06:46:30 +00:00
Chris Lattner f47015bc74 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.

llvm-svn: 44701

Chris Lattner f6a8156e4f implement __builtin_return_addr(0) on ppc.

llvm-svn: 44244
 2007-11-19 21:43:22 +00:00
Dale Johannesen a674612d94 Testcase from PR 1508 (although its's somewhat 
orthogonal to the main problem there)

llvm-svn: 44194
 2007-11-16 23:16:35 +00:00
Evan Cheng 17b0e3e1ae Skip over deleted val#'s. 
llvm-svn: 43700
 2007-11-05 06:46:45 +00:00
Bill Wendling b0bfd69684 On second thought. Remove this as it should never be generated in the first 
place.

llvm-svn: 43400
 2007-10-26 20:34:37 +00:00
Bill Wendling 6d15b32c15 - 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.

llvm-svn: 43398
 2007-10-26 20:24:42 +00:00
Bill Wendling e3b859298a If there's an unaligned memcpy to/from the stack, don't lower it. Just call the 
memcpy library function instead.

llvm-svn: 43270
 2007-10-23 23:32:40 +00:00
Evan Cheng ec271b104c Temporary solution: added a different set of BCTRL_Macho / BCTRL_ELF with right callee-saved defs set for ppc64. 
llvm-svn: 43248
 2007-10-23 06:42:42 +00:00
Evan Cheng bdbed66333 Use ptr type in the immediate field of a BxA instruction so we don't end up selecting 32-bit call instruction for ppc64. 
llvm-svn: 43228

Bill Wendling 070aca5d25 Pointer arithmetic should be done with the index the same size as the pointer.

Chris Lattner 1366653e2f Fix a bug handling frame references in ppc inline asm when the frame offset 
doesn't fit into 16 bits.

llvm-svn: 43032
 2007-10-16 18:00:18 +00:00
Dale Johannesen c0154c06d6 First round of ppc long double. call/return and 
basic arithmetic works.
Rename RTLIB long double functions to distinguish
different flavors of long double; the lib functions
have different names, alas.

Evan Cheng c16847b157 Sometimes a MI can define a register as well as defining a super-register at the 
same time. Do not mark the "smaller" def as dead.
