* Add a last resort tryInstructionSplit() to RAGreedy.Jakob Stoklund Olesen2012-05-231-1/+65
| | | | | | | | | | | | | Live ranges with a constrained register class may benefit from splitting around individual uses. It allows the remaining live range to use a larger register class where it may allocate. This is like spilling to a different register class. This is only attempted on constrained register classes. <rdar://problem/11438902> llvm-svn: 157354

* Correctly deal with identity copies in RegisterCoalescer.Jakob Stoklund Olesen2012-05-231-7/+18
| | | | | | | | | | | | | | | | | Now that the coalescer keeps live intervals and machine code in sync at all times, it needs to deal with identity copies differently. When merging two virtual registers, all identity copies are removed right away. This means that other identity copies must come from somewhere else, and they are going to have a value number. Deal with such copies by merging the value numbers before erasing the copy instruction. Otherwise, we leave dangling value numbers in the live interval. This fixes PR12927. llvm-svn: 157340

* Fix PR12858, a crash due to GVN's PRE not fully removing an instruction from theDuncan Sands2012-05-221-6/+12
| | | | | | | | | | | | leader table. That's because it wasn't expecting instructions to turn up as leader for a value number that is not its own, but equality propagation could create this situation. One solution is to have the leader table use a WeakVH but this slows down GVN by about 5%. Instead just have equality propagation not add instructions to the leader table, only constants and arguments. In theory this might cause GVN to run more (each time it changes something it runs again) but it doesn't seem to occur enough to cause a slow down. llvm-svn: 157251
