* Generalize target-independent folding rules for sizeof to handle moreDan Gohman2010-02-014-64/+267
| | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | 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.

| | | | | | | | | | | | | | 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
