From 83ce5f181f9fdd0633b698e31958d35b3583b332 Mon Sep 17 00:00:00 2001 From: "Michael J. Spencer" Date: Thu, 21 Oct 2010 00:08:21 +0000 Subject: CodeGen-Windows: Only emit _fltused if a VarArg function is called with floating point args. This should be the minimum set of functions that could possibly need it. llvm-svn: 116978 --- llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp') diff --git a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp index a68b7b0f947..4be2525cfa1 100644 --- a/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp +++ b/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp @@ -5030,16 +5030,16 @@ void SelectionDAGBuilder::visitCall(const CallInst &I) { // See if any floating point values are being passed to this external // function.
