* Update malloc call creation code (AllocType is now the element type of the ↵Victor Hernandez2009-09-187-102/+145
| | | | | | | | | | | | | | | | | | | | 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.
