Chris Lattner 01a2202138 Add support for CombineTo, allowing the dag combiner to replace nodes with ... multiple results. Use this support to implement trivial store->load forwarding, implementing CodeGen/PowerPC/store-load-fwd.ll. Though this is the most simple case and can be extended in the future, it is still useful. For example, it speeds up 197.parser by 6.2% by avoiding an LSU reject in xalloc: stw r6, lo16(l5_end_of_array)(r2) addi r2, r5, -4 stwx r5, r4, r2 - lwzx r5, r4, r2 - rlwinm r5, r5, 0, 0, 30 stwx r5, r4, r2 lwz r2, -4(r4) ori r2, r2, 1 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23690 91177308-0d34-0410-b5e6-96231b3b80d8		2005-10-10 22:04:48 +00:00
