Dan Gohman	44e25ed254	Don't enable the post-RA scheduler on x86 except at -O3. In its ... current form, it is too expensive in compile time. llvm-svn: 90781	2009-12-07 19:04:31 +00:00
Jakob Stoklund Olesen	f07d6129a2	Use CFG connectedness as a secondary sort key when deciding the order of copy coalescing. ... This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to coalesce because intervals are more complicated, so handling them first gives a greater chance of success. llvm-svn: 90194	2009-12-01 03:03:00 +00:00
Evan Cheng	eb82c3743a	Turn on post-alloc scheduling for x86. ... llvm-svn: 84431	2009-10-18 19:57:27 +00:00
Evan Cheng	7714c8412d	Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks. ... llvm-svn: 82311	2009-09-19 09:51:03 +00:00
