2009-10-26Rename MallocHelper as MallocFreeHelper, since it now also identifies calls ↵Victor Hernandez

2009-10-26Remove FreeInst.Victor Hernandez
Remove LowerAllocations pass. Update some more passes to treate free calls just like they were treating FreeInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85176 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-24Auto-upgrade free instructions to calls to the builtin free function.Victor Hernandez
Update all analysis passes and transforms to treat free calls just like FreeInst. Remove RaiseAllocations and all its tests since FreeInst no longer needs to be raised. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84987 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-15Fix bug where array malloc with unexpected computation of the size argument ↵Victor Hernandez
resulted in MallocHelper identifying the malloc as a non-array malloc. This broke GlobalOpt's optimization of stores of mallocs to global variables. The fix is to classify malloc's into 3 categories: 1. non-array mallocs 2. array mallocs whose array size can be determined 3. mallocs that cannot be determined to be of type 1 or 2 and cannot be optimized getMallocArraySize() returns NULL for category 3, and all users of this function must avoid their malloc optimization if this function returns NULL. Eventually, currently unexpected codegen for computing the malloc's size argument will be supported in isArrayMalloc() and getMallocArraySize(), extending malloc optimizations to those examples. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84199 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Update malloc call creation code (AllocType is now the element type of the ↵Victor Hernandez
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.
