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
Nate Begeman	65ffd8fbf4	Remove option to make SetCC illegal on PowerPC after long discussion with ... Chris. This will be accomplished through correctly modeling CR's and subregs. llvm-svn: 23056	2005-08-25 20:01:10 +00:00

Nate Begeman	371e49515d	Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty ... fixme from the PowerPC backend. Emit slightly better code for legalizing select_cc. llvm-svn: 22805	2005-08-16 19:49:35 +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
