| | | | | | | | | | | | | | | | | | malloc, not the resulting type). In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants. Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array. Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type. Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls. Add verification for malloc calls. Reviewed by Dan Gohman. llvm-svn: 82257

This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now). llvm-svn: 82214
