* SplitCriticalEdge can sometimes split the edge from an invoke to a landingJohn McCall2011-06-092-29/+276
| | | | | | | | | | | | | | pad, separating the exception and selector calls from the new lpad. Teaching it not to do that, or to properly adjust the CFG afterwards, is out of scope because it would require the other edges to the landing pad to be split as well (effectively). Instead, just recover from the most likely cases during inlining. The best long-term solution is to change the exception representation and commit to either requiring or not requiring the more complex edge-splitting logic; this is just a shorter-term hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132799 91177308-0d34-0410-b5e6-96231b3b80d8

* Move TableGen's register bank classes to their own source file.Jakob Stoklund Olesen2011-06-093-73/+102
| | | | | | | | | | | I'll be moving some more code there to gather all of the register-specific stuff in one place. Currently it is shared between CodeGenTarget and RegisterInfoEmitter. The plan is that CodeGenRegisters can compute the full register bank structure while RegisterInfoEmitter only will handle the printing part. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132788 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove custom allocation order boilerplate that is no longer needed.Jakob Stoklund Olesen2011-06-0914-663/+56
| | | | | | | | | | | | | | | | | | | | The register allocators automatically filter out reserved registers and place the callee saved registers last in the allocation order, so custom methods are no longer necessary just for that. Some targets still use custom allocation orders: ARM/Thumb: The high registers are removed from GPR in thumb mode. The NEON allocation orders prefer to use non-VFP2 registers first. X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble. SystemZ: Some of the allocation orders are omitting R12 aliases without explanation. I don't understand this target well enough to fix that. It looks like all the boilerplate could be removed by reserving the right registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132781 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify local live range splitting's safeguard to fix PR10070.Jakob Stoklund Olesen2011-06-062-89/+68
| | | | | | | | | | | | | | | When local live range splitting creates a live range with the same number of instructions as the old range, mark it as RS_Local. When such a range is seen again, require that it be split in a way that reduces the number of instructions. That guarantees we are making progress while still being able to perform 3 -> 2+3 splits as required by PR10070. This also means that the PrevSlot map is no longer needed. This was also used to estimate new spill weights, but that is no longer necessary after slotIndexes::insertMachineInstrInMaps() got the extra Late insertion argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132697 91177308-0d34-0410-b5e6-96231b3b80d8
