2010-02-01Update this test for a trivial register allocation difference.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94989 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-01Generalize target-independent folding rules for sizeof to handle moreDan Gohman
cases, and implement target-independent folding rules for alignof and offsetof. Also, reassociate reassociative operators when it leads to more folding. Generalize ScalarEvolution's isOffsetOf to recognize offsetof on arrays. Rename getAllocSizeExpr to getSizeOfExpr, and getFieldOffsetExpr to getOffsetOfExpr, for consistency with analagous ConstantExpr routines. Make the target-dependent folder promote GEP array indices to pointer-sized integers, to make implicit casting explicit and exposed to subsequent folding. And add a bunch of testcases for this new functionality, and a bunch of related existing functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94987 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-01fix rdar://7590304, a miscompilation of objc apps on arm. The callerChris Lattner
of objc message send was getting marked arm_apcscc, but the prototype isn't. This is fine at runtime because objcmsgsend is implemented in assembly. Only turn a mismatched caller and callee into 'unreachable' if the callee is a definition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94986 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-01fix rdar://7590304, an infinite loop in instcombine. In the invokeChris Lattner
case, instcombine can't zap the invoke for fear of changing the CFG. However, we have to do something to prevent the next iteration of instcombine from inserting another store -> undef before the invoke thereby getting into infinite iteration between dead store elim and store insertion. Just zap the callee to null, which will prevent the next iteration from doing anything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94985 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-01Fix pr6198 by moving the isSized() check to an outer conditional.Bob Wilson
The testcase from pr6198 does not crash for me -- I don't know what's up with that -- so I'm not adding it to the tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94984 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-31Do not mark no-return calls tail calls. It'll screw up special calls like ↵Evan Cheng

2010-01-30Fix a gross typo: ARMv6+ may or may not support unaligned memory operations.Anton Korobeynikov
Even if they are suported by the core, they can be disabled (this is just a configuration bit inside some register). Allow unaligned memops on darwin and conservatively disallow them otherwise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94889 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-30Check alignment of loads when deciding whether it is safe to execute themBob Wilson
unconditionally. Besides checking the offset, also check that the underlying object is aligned as much as the load itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94875 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-30MC/X86 AsmParser: Handle absolute memory operands correctly. We were doingDaniel Dunbar
something totally broken and parsing them as immediates, but the .td file also had the wrong match class so things sortof worked. Except, that is, that we would parse movl $0, %eax as movl 0, %eax Feel free to guess how well that worked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94869 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-30Remove ARM-specific calling convention from this test. Target data isBob Wilson
needed for this test, but otherwise, there's nothing ARM-specific about it and no need to specify the calling convention. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94862 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-30FileCheck: When looking for "possible matches", only compare against the prefixDaniel Dunbar
line. Turns out edit_distance can be slow if the string we are scanning for happens to be quite large. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94860 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-29Keep iterating over all uses when meeting a phi node in ↵Jakob Stoklund Olesen
AllUsesOfValueWillTrapIfNull(). This bug was exposed by my inliner cost changes in r94615, and caused failures of lencod on most architectures when building with LTO. This patch fixes lencod and 464.h264ref on x86-64 (and likely others). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94858 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29MC/X86: Add a nice X86 assembler matcher test case from Kevin Enderby.Daniel Dunbar
- This test case is auto generated, and has been verified to round-trip correctly through llvm-mc by checking the assembled .o file before and after piping through llvm-mc. It will be extended over time as the matcher grows support for more instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94857 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Modified encoding bits specification for VFP instructions. In particular, the DJohnny Chen
bit (Inst{22}) and the M bit (Inst{5}) should be left unspecified. For binary format instructions, Inst{6} and Inst{4} need to specified for proper decodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94855 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94853 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-29Preserve load alignment in instcombine transformations. I've been unable toBob Wilson
create a testcase where this matters. The select+load transformation only occurs when isSafeToLoadUnconditionally is true, and in those situations, instcombine also changes the underlying objects to be aligned. This seems like a good idea regardless, and I've verified that it doesn't pessimize the subsequent realignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94850 91177308-0d34-0410-b5e6-96231b3b80d8
