Interesting approach. Instead of adding this to one target's .td file, can you please investigate whether we can enable the dag combine xform at DAGCombiner.cpp:3412 now? The primary thing blocking that xform was that we need to know (in this case) that an f32 store doesn't require greater alignment than an i32 store has. -Chris _______________________________________________ llvm-commits mailing list llvm-commits@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/llvm-commits
