From b5dae003252d8e650a32bfdf33cba5aed8e41e40 Mon Sep 17 00:00:00 2001 From: Dale Johannesen Date: Thu, 26 Jun 2008 01:51:13 +0000 Subject: Fixes the last x86-64 test failure in compat.exp: <16 x float> is 64-byte aligned (for some reason), which gets us into the stack realignment code. The computation changing FP-relative offsets to SP-relative was broken, assiging a spill temp to a location also used for parameter passing. This fixes it by rounding up the stack frame to a multiple of the largest alignment (I concluded it wasn't fixable without doing this, but I'm not very sure.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52750 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/TableGen/RegisterInfoEmitter.cpp | 2 ++ 1 file changed, 2 insertions(+) (limited to 'utils') diff --git a/utils/TableGen/RegisterInfoEmitter.cpp b/utils/TableGen/RegisterInfoEmitter.cpp index 9277335..2f253ff 100644 --- a/utils/TableGen/RegisterInfoEmitter.cpp +++ b/utils/TableGen/RegisterInfoEmitter.cpp @@ -64,6 +64,8 @@ void RegisterInfoEmitter::runHeader(std::ostream &OS) { << " virtual int getDwarfRegNumFull(unsigned RegNum, " << "unsigned Flavour) const;\n" << " virtual int getDwarfRegNum(unsigned RegNum, bool isEH) const = 0;\n" + << " virtual bool needsStackRealignment(const MachineFunction &) const\n" + << " { return false; }\n" << " unsigned getSubReg(unsigned RegNo, unsigned Index) const;\n" << "};\n\n"; -- cgit v1.1
