Simplify the test. NFC. Since the main file was empty, we can just copy the content of the Input file into it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223666 91177308-0d34-0410-b5e6-96231b3b80d8 2014-12-08 17:22:06 +00:00			`; RUN: llvm-link %s -S -o - \| FileCheck %s`

Set comdats when lazily linking functions. We were setting the comdat when functions were copied in the initial pass, but not when they were linked only when we found out that they are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@215765 91177308-0d34-0410-b5e6-96231b3b80d8 2014-08-15 20:17:08 +00:00
Don't crash when the key of a comdat is lazily linked. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@223673 91177308-0d34-0410-b5e6-96231b3b80d8 2014-12-08 18:05:48 +00:00			`; CHECK-DAG: $c = comdat any`
