* Allow GlobalValues to vectorize with AliasAnalysisRenato Golin2013-02-212-35/+510
| | | | | | | | | | | | | | | | | | | | | Storing the load/store instructions with the values and inspect them using Alias Analysis to make sure they don't alias, since the GEP pointer operand doesn't take the offset into account. Trying hard to not add any extra cost to loads and stores that don't overlap on global values, AA is *only* calculated if all of the previous attempts failed. Using biggest vector register size as the stride for the vectorization access, as we're being conservative and the cost model (which calculates the real vectorization factor) is only run after the legalization phase. We might re-think this relationship in the future, but for now, I'd rather be safe than sorry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175818 91177308-0d34-0410-b5e6-96231b3b80d8

* Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky2013-02-2156-587/+558
| | | | | | | | | | | | | | | | | to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | exists solely to enable it to call itself for i8 with some registers.

* PPCDAGToDAGISel::PostprocessISelDAG()Bill Schmidt2013-02-218-1/+342
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the PPCDAGToDAGISel::PostprocessISelDAG virtual method to perform post-selection peephole optimizations on the DAG representation. One optimization is implemented here: folds to clean up complex addressing expressions for thread-local storage and medium code model. It will also be useful for large code model sequences when those are added later. I originally thought about doing this on the MI representation prior to register assignment, but it's difficult to do effective global dead code elimination at that point. DCE is trivial on the DAG representation. A typical example of a candidate code sequence in assembly: addis 3, 2, globalvar@toc@ha addi 3, 3, globalvar@toc@l lwz 5, 0(3) When the final instruction is a load or store with an immediate offset of zero, the offset from the add-immediate can replace the zero, provided the relocation information is carried along: addis 3, 2, globalvar@toc@ha lwz 5, globalvar@toc@l(3) Since the addi can in general have multiple uses, we need to only delete the instruction when the last use is removed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175697 91177308-0d34-0410-b5e6-96231b3b80d8
