2010-02-01Add an option to GVN to remove all partially redundant loads. This is currentlyBob Wilson
disabled by default. This divides the existing load PRE code into 2 phases: first it checks that it is safe to move the load to each of the predecessors where it is unavailable, and then if it is safe, the code is changed to move the load.

2010-02-01Fixed a couple of optimization with EXTRACT_VECTOR_ELT that assumes the resultMon P Wang
type is the same as the element type of the vector. EXTRACT_VECTOR_ELT can be used to extended the width of an integer type. This fixes a bug for Generic/vector-casts.ll on a ppc750. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94990 91177308-0d34-0410-b5e6-96231b3b80d8

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
