From 0de089a4d0db7e47ac8a5d8bd087c196231c7572 Mon Sep 17 00:00:00 2001 From: Chandler Carruth Date: Mon, 16 Apr 2012 13:49:09 +0000 Subject: [PATCH] Remove an overly brittle test. This test will no longer be interesting once we start changing the block layout, so just nuke it. If anyone has ideas about how to craft a code layout agnostic form of the test please let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154815 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/CodeGen/X86/2011-09-14-valcoalesce.ll | 174 --------------------- 1 file changed, 174 deletions(-) delete mode 100644 test/CodeGen/X86/2011-09-14-valcoalesce.ll diff --git a/test/CodeGen/X86/2011-09-14-valcoalesce.ll b/test/CodeGen/X86/2011-09-14-valcoalesce.ll deleted file mode 100644 index 1068d1b704b..00000000000 --- a/test/CodeGen/X86/2011-09-14-valcoalesce.ll +++ /dev/null @@ -1,174 +0,0 @@ -; RUN: llc < %s -march=x86 | FileCheck %s -; -; Test RegistersDefinedFromSameValue.
