From d2eae62e93fc6e398263a952609b6ea60a204802 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Mon, 9 Apr 2007 00:46:10 +0000 Subject: [PATCH] Fix CodeGen/Generic/2007-04-08-MultipleFrameIndices.ll and PR1308: some instructions can have multiple frame indices in them. If this happens, rewrite all of them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35785 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/CodeGen/PrologEpilogInserter.cpp | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/lib/CodeGen/PrologEpilogInserter.cpp b/lib/CodeGen/PrologEpilogInserter.cpp index b0e7bd8fcbd..b76fa3f4eb4 100644 --- a/lib/CodeGen/PrologEpilogInserter.cpp +++ b/lib/CodeGen/PrologEpilogInserter.cpp @@ -504,7 +504,11 @@ void PEI::replaceFrameIndices(MachineFunction &Fn) { // If this instruction has a FrameIndex operand, we need to use that // target machine register info object to eliminate it.
