From 81eb42d8caf4aacfc126504953e73f7b646c7b67 Mon Sep 17 00:00:00 2001 From: David Greene Date: Thu, 12 Nov 2009 20:25:07 +0000 Subject: Make FixedStackPseudoSourceValue a first-class PseudoSourceValue by making it visible to clients and adding LLVM-style cast capability. This will be used by AsmPrinter to determine when to emit spill comments for an instruction. llvm-svn: 87019 --- llvm/lib/CodeGen/PseudoSourceValue.cpp | 25 ++----------------------- 1 file changed, 2 insertions(+), 23 deletions(-) (limited to 'llvm/lib/CodeGen/PseudoSourceValue.cpp') diff --git a/llvm/lib/CodeGen/PseudoSourceValue.cpp b/llvm/lib/CodeGen/PseudoSourceValue.cpp index 5507646878c..e95f017fc39 100644 --- a/llvm/lib/CodeGen/PseudoSourceValue.cpp +++ b/llvm/lib/CodeGen/PseudoSourceValue.cpp @@ -43,35 +43,14 @@ static const char *const PSVNames[] = { // Eventually these should be uniqued on LLVMContext rather than in a managed // static.
