Bruno Cardoso Lopes	10f234f1a7	Fix vbroadcast matching logic to early unmatch if the node doesn't have ... only one use. Fix PR10825. llvm-svn: 138951	2011-09-01 18:15:06 +00:00
Bruno Cardoso Lopes	98531dfd08	Introduce matching patterns for vbroadcast AVX instruction. The idea is to ... match splats in the form (splat (scalar_to_vector (load ...))) whenever the load can be folded. All the logic and instruction emission is working but because of PR8156, there are no ways to match loads, cause they can never be folded for splats. Thus, the tests are XFAILed, but I've tested and exercised all the logic using a relaxed version for checking the foldable loads, as if the bug was already fixed. This should work out of the box once PR8156 gets fixed since MayFoldLoad will work as expected. llvm-svn: 137810	2011-08-17 02:29:19 +00:00
