* 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

* 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
