Eli Friedman f99e7e6643 PR7853: fix a silly mistake introduced in r101899, and add a test to make sure 
it doesn't regress again.

Dale Johannesen a3bd31a923 Use sdmem and sse_load_f64 (etc.) for the vector 
form of CMPSD (etc.)  Matching a 128-bit memory
operand is wrong, the instruction uses only 64 bits
(same as ADDSD etc.)  8193553.

Dan Gohman e68958fcdf Implement a proper getModRefInfo for va_arg.

Rafael Espindola 027d5bcf89 Fix eabi calling convention when a 64 bit value shadows r3. 
Without this what was happening was:

* R3 is not marked as "used"
* ARM backend thinks it has to save it to the stack because of vaarg
* Offset computation correctly ignores it
* Offsets are wrong

Eric Christopher e1fb772aa5 Add an option to always emit realignment code for a particular module.

Dan Gohman 884dd752c3 Implement AccessesArguments checking in the two-callsite form 
of BasicAA::getModRefInfo. This allows BasicAA to say that two
memset calls to non-aliasing memory locations don't interfere.

llvm-svn: 110393
 2010-08-05 23:34:50 +00:00
Dan Gohman 26ef7c7ab7 Fix memdep's code for reasoning about dependences between two calls. A Ref 
response from getModRefInfo is not useful here. Instead, check for identical
calls only in the NoModRef case.

Reapply r110270, and strengthen it to compensate for the memdep changes.
When both calls are readonly, there is no dependence between them.

Dan Gohman c53ee449a5 Move x86-specific tests out of test/Transforms/LoopStrengthReduce and 
into test/CodeGen/X86, so that they aren't run when the x86 target is
not enabled.

Fix uglygep.ll to not be x86-specific.

Daniel Dunbar 57e3f71538 tests: Mark MC/AsmParser tests as requiring x86 for now -- almost all of them

Dan Gohman 109561845b The trouble with testing for "ModRef" and "NoModRef" is that 
one is a suffix of the other, and FileCheck accepts superstrings.
Adjust the output to avoid this problem.

Bill Wendling ca1cb13646 The lower invoke pass needs to have unreachable code elimination run after it 
because it could create such things. This fixes a MingW buildbot test failure.

llvm-svn: 110279
 2010-08-04 23:36:02 +00:00
Dan Gohman bd33dab633 The two-callsite form of AliasAnalysis::getModRefInfo is documented 
to return Ref if the left callsite only reads memory read or written
by the right callsite; fix BasicAliasAnalysis to implement this.

Add AliasAnalysisEvaluator support for testing the two-callsite
form of getModRefInfo.

Jakob Stoklund Olesen 011ff9bec9 OK, that's it. This test is going away now. But don't worry, I am taking it to a 
nice farm in the country where it can play with other tests. And bunnies.

It is not clear what is being tested, and the revision history shows a bunch of
random changes to the expected instruction count. Clearly, we are just fudging
it to pass whenever it fails.

Kalle Raiskila 77558b7d13 More SPU v2f32 stuff added: insertelement and shuffle. 
llvm-svn: 110038
 2010-08-02 11:22:10 +00:00
Kalle Raiskila 68b3886678 Add preliminary v2f32 support for SPU. Like with v2i32, we just 
duplicate the instructions and operate on half vectors. 

Also reorder code in SPUInstrInfo.td for better coherency.

Owen Anderson 8f306a779b Re-apply the infamous r108614, with a fix pointed out by Dirk Steinke. 
llvm-svn: 110036
 2010-08-02 09:32:13 +00:00
Kalle Raiskila 622f8eb981 Add preliminary v2i32 support for SPU backend. As there are no 
such registers in SPU, this support boils down to "emulating" 
them by duplicating instructions on the general purpose registers. 

This adds the most basic operations on v2i32: passing parameters,
addition, subtraction, multiplication and a few others.
