From 3e6a35076ed072525d3eda1945033863b613aef8 Mon Sep 17 00:00:00 2001 From: Chris Lattner Date: Wed, 10 May 2006 06:38:32 +0000 Subject: [PATCH] Fix the PowerPC JIT-only failure on UnitTests/Vector/sumarray-dbl, which is really a bad codegen bug that LLC happens to get lucky with. I must chat with Nate for the proper fix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28213 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Target/PowerPC/PPCRegisterInfo.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/Target/PowerPC/PPCRegisterInfo.cpp b/lib/Target/PowerPC/PPCRegisterInfo.cpp index 36cb869abda..0b961cb8074 100644 --- a/lib/Target/PowerPC/PPCRegisterInfo.cpp +++ b/lib/Target/PowerPC/PPCRegisterInfo.cpp @@ -506,11 +506,11 @@ void PPCRegisterInfo::emitPrologue(MachineFunction &MF) const { // If there is a preferred stack alignment, align R1 now if (MaxAlign > TargetAlign) { assert(isPowerOf2_32(MaxAlign) && MaxAlign < 32767 && "Invalid alignment!"); - assert(isInt16(MaxAlign-NumBytes) && "Unhandled stack size and alignment!"); + assert(isInt16(0-NumBytes) && "Unhandled stack size and alignment!"); BuildMI(MBB, MBBI, PPC::RLWINM, 4, PPC::R0) .addReg(PPC::R1).addImm(0).addImm(32-Log2_32(MaxAlign)).addImm(31); BuildMI(MBB, MBBI, PPC::SUBFIC,2,PPC::R0).addReg(PPC::R0) - .addImm(MaxAlign-NumBytes); + .addImm(0-NumBytes); BuildMI(MBB, MBBI, PPC::STWUX, 3) .addReg(PPC::R1).addReg(PPC::R1).addReg(PPC::R0); } else if (NumBytes <= 32768) {
