* Re-commit r86077 now that r86290 fixes the 179.art and 175.vpr ARM regressions.Victor Hernandez2009-11-071-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | Here is the original commit message: This commit updates malloc optimizations to operate on malloc calls that have constant int size arguments. Update CreateMalloc so that its callers specify the size to allocate: 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@86311 91177308-0d34-0410-b5e6-96231b3b80d8

* Create a ScalarEvolution-based AliasAnalysis implementation.Dan Gohman2009-08-261-0/+194
| | | | | | | | | | | | | | | | | This is a simple AliasAnalysis implementation which works by making ScalarEvolution queries. ScalarEvolution has a more complete understanding of arithmetic than BasicAA's collection of ad-hoc checks, so it handles some cases that BasicAA misses, for example p[i] and p[i+1] within the same iteration of a loop. This is currently experimental. It may be that the main use for this pass will be to help find cases where BasicAA can be profitably extended, or to help in the development of the overall AliasAnalysis infrastructure, however it's also possible that it could grow up to become a directly useful pass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80098 91177308-0d34-0410-b5e6-96231b3b80d8
