Chris Lattner	b2854fadda	Make fsel emission work with both the pattern and dag-dag selectors, by ... giving it a non-instruction opcode. The dag->dag selector used to not select the operands of the fsel, because it thought that whole tree was already selected. llvm-svn: 23091	2005-08-26 20:25:03 +00:00
Chris Lattner	f3d06c6417	add initial support for converting select_cc -> fsel in the legalizer ... instead of in the backend. This currently handles fsel cases with registers, but doesn't have the 0.0 and -0.0 optimization enabled yet. Once this is finished, special hack for fp immediates can go away. llvm-svn: 23075	2005-08-26 00:52:45 +00:00
Chris Lattner	f22556d3ad	Pull the LLVM -> DAG lowering code out of the pattern selector so that it ... can be shared with the DAG->DAG selector. llvm-svn: 22799	2005-08-16 17:14:42 +00:00
