Hal Finkel 838a7fb1a3 RegScavenger should not exclude undef uses ... When computing currently-live registers, the register scavenger excludes undef uses. As a result, undef uses are ignored when computing the restore points of registers spilled into the emergency slots. While the register scavenger normally excludes from consideration, when scavenging, registers used by the current instruction, we need to not exclude undef uses. Otherwise, we might end up requiring more emergency spill slots than we have (in the case where the undef use *is* the currently-spilled register). Another bug found by llvm-stress. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186067 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-11 05:55:57 +00:00
