Add -verify-machineinstrs to these fast-isel test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168723 91177308-0d34-0410-b5e6-96231b3b80d8 2012-11-27 20:49:56 +00:00			`; RUN: llc -O0 -verify-machineinstrs -optimize-regalloc -regalloc=basic < %s`
Re-committing r130454, which does not in fact break anything. Fix a rather obscure crash caused by ARM fast-isel generating code which redefines a register. rdar://problem/9338332 . git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130539 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-29 21:22:56 +00:00			`; This isn't exactly a useful set of command-line options, but check that it`
