Thanks to David Blaikie for the suggestion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@235149 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/test/DebugInfo/X86/inlined-formal-parameter.ll b/test/DebugInfo/X86/inlined-formal-parameter.ll index e31fa89b340..3ac595f7174 100644 --- a/test/DebugInfo/X86/inlined-formal-parameter.ll +++ b/test/DebugInfo/X86/inlined-formal-parameter.ll @@ -1,105 +1,75 @@ ;
