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

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.

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.
