* Add -mtriple to llc commands, attempting to fix buildbot failures.Bob Wilson2009-11-051-2/+2

* Update CreateMalloc so that its callers specify the size to allocate:Victor Hernandez2009-11-0510-44/+72
| | | | | | | | | | | | | | | | | | | MallocInst-autoupgrade users use non-TargetData-computed allocation sizes. Optimization uses use TargetData to compute the allocation size. Now that malloc calls can have constant sizes, update isArrayMallocHelper() to use TargetData to determine the size of the malloced type and the size of malloced arrays. Extend getMallocType() to support malloc calls that have non-bitcast uses. Update OptimizeGlobalAddressOfMalloc() to optimize malloc calls that have non-bitcast uses. The bitcast use of a malloc call has to be treated specially here because the uses of the bitcast need to be replaced and the bitcast needs to be erased (just like the malloc call) for OptimizeGlobalAddressOfMalloc() to work correctly. Update PerformHeapAllocSRoA() to optimize malloc calls that have non-bitcast uses. The bitcast use of the malloc is not handled specially here because ReplaceUsesOfMallocWithGlobal replaces through the bitcast use. Update OptimizeOnceStoredGlobal() to not care about the malloc calls' bitcast use. Update all globalopt malloc tests to not rely on autoupgraded-MallocInsts, but instead use explicit malloc calls with correct allocation sizes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86077 91177308-0d34-0410-b5e6-96231b3b80d8

* move two functions up higher in the file. Delete a useless argumentChris Lattner2009-11-041-1/+38
| | | | | | | | | | | | | | | to EmitGEPOffset. Implement some new transforms for optimizing subtracts of two pointer to ints into the same vector. This happens for C++ iterator idioms for example, stringmap takes a const char* that points to the start and end of a string. Once inlined, we want the pointer difference to turn back into a length.
