Tom Stellard	e8c59f575b	R600: Disable the BFE pattern ... This pattern uses an SDNodeXForm, which isn't being emitted for some reason. I can get it to work by attaching the PatLeaf that has the XForm to the argument in the output pattern, but this results in an immediate being used in a register operand, which the backend can't handle yet. llvm-svn: 199918	2014-01-23 18:49:33 +00:00
Tom Stellard	7edf38bf1f	R600: Remove AMDILPeeopholeOptimizer and replace optimizations with tablegen patterns ... The BFE optimization was the only one we were actually using, and it was emitting an intrinsic that we don't support. https://bugs.freedesktop.org/show_bug.cgi?id=64201 Reviewed-by: Christian König <christian.koenig@amd.com> NOTE: This is a candidate for the 3.3 branch. llvm-svn: 181580	2013-05-10 02:09:45 +00:00
