Convert test/CodeGen/X86/omit-label.ll to FileCheck and add a testcase for PR4732. test/CodeGen/Thumb2/thumb2-ifcvt2.ll sees a diff with this commit due to it being bugpoint-reduced to the point where it doesn't matter what the condition for the branch is. Add some more interesting code to test/CodeGen/X86/2009-08-06-branchfolder-crash.ll, which is the testcase that originally motivated the RemoveDuplicateSuccessor code, to help verify that the original problem isn't being re-broken. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79338 91177308-0d34-0410-b5e6-96231b3b80d8

* Refine EarlyClobber assert in register scavenger.Jakob Stoklund Olesen2009-08-15
| | | | | | | | | | | | | | It is legal for an inline asm operand to use an earlyclobber register if the use operand is tied to the earlyclobber operand. The issue is discussed here: http://gcc.gnu.org/ml/gcc/1999-04n/msg00431.html We should perhaps let only the machine code verifier worry about these finer details. EarlyClobber operands are not really interesting to the scavenger. This fixes PR4528 for the third time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79122 91177308-0d34-0410-b5e6-96231b3b80d8
