2012-11-26Add an assertion to ensure freezeReservedRegs() is only ever called once.Chad Rosier
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168633 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-26Now that the X86 Maximal Stack Alignment Check pass has been removed (i.e.,Chad Rosier
r168627), we no longer need to call the freezeReservedRegs() function a second time. Previously, this pass was conservatively adding the FP to the set of reserved registers, requiring the second update to the reserved registers. rdar://12719844 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168631 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-15[reg scavenger] Fix the isUsed/isAliasUsed functions so as to not report a falseChad Rosier
positive. In this particular case, R6 was being spilled by the register scavenger when it was in fact dead. The isUsed function reported R6 as used because the R6_R7 alias was reserved (due to the fact that we've reserved R7 as the FP). The solution is to only check if the original register (i.e., R6) isReserved and not the aliases. The aliases are only checked to make sure they're available. The test case is derived from one of the nightly tester benchmarks and is rather intractable and difficult to reproduce, so I haven't included it. rdar://12592448 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168054 91177308-0d34-0410-b5e6-96231b3b80d8
