From 30679e691db00a613e90ef01416aab2d4b371c0c Mon Sep 17 00:00:00 2001 From: Jim Laskey Date: Mon, 15 Aug 2005 17:14:19 +0000 Subject: [PATCH] Changed code gen for int to f32 to use rounding. This makes FP results consistent with gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22791 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCISelPattern.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/Target/PowerPC/PPCISelPattern.cpp b/lib/Target/PowerPC/PPCISelPattern.cpp index 9831111eabc..f632d0ebf04 100644 --- a/lib/Target/PowerPC/PPCISelPattern.cpp +++ b/lib/Target/PowerPC/PPCISelPattern.cpp @@ -2312,7 +2312,7 @@ unsigned ISel::SelectExpr(SDOperand N, bool Recording) { addFrameReference(BuildMI(BB, PPC::STW, 3).addReg(Tmp1), FrameIdx, 4); addFrameReference(BuildMI(BB, PPC::LFD, 2, Tmp2), FrameIdx); // Generate the return value with a subtract - BuildMI(BB, PPC::FSUB, 2, Result).addReg(Tmp2).addReg(ConstF); + BuildMI(BB, DestType == MVT::f64 ?
