From 0b57cec536236d46e3dba9bd041533462f33dbb7 Mon Sep 17 00:00:00 2001 From: Dimitry Andric Date: Fri, 20 Dec 2019 19:53:05 +0000 Subject: Move all sources from the llvm project into contrib/llvm-project. This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. --- .../llvm/lib/Target/X86/X86MachineFunctionInfo.cpp | 30 ++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/Target/X86/X86MachineFunctionInfo.cpp (limited to 'contrib/llvm-project/llvm/lib/Target/X86/X86MachineFunctionInfo.cpp') diff --git a/contrib/llvm-project/llvm/lib/Target/X86/X86MachineFunctionInfo.cpp b/contrib/llvm-project/llvm/lib/Target/X86/X86MachineFunctionInfo.cpp new file mode 100644 index 000000000000..05f846bfb219 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/Target/X86/X86MachineFunctionInfo.cpp @@ -0,0 +1,30 @@ +//===-- X86MachineFunctionInfo.cpp - X86 machine function info ------------===// +// +// Part of the LLVM Project, under the Apache License v2.0 with LLVM Exceptions. +// See https://llvm.org/LICENSE.txt for license information. +// SPDX-License-Identifier: Apache-2.0 WITH LLVM-exception +// +//===----------------------------------------------------------------------===// + +#include "X86MachineFunctionInfo.h" +#include "X86RegisterInfo.h" +#include "llvm/CodeGen/MachineRegisterInfo.h" +#include "llvm/CodeGen/TargetSubtargetInfo.h" + +using namespace llvm; + +void X86MachineFunctionInfo::anchor() { } + +void X86MachineFunctionInfo::setRestoreBasePointer(const MachineFunction *MF) { + if (!RestoreBasePointerOffset) { + const X86RegisterInfo *RegInfo = static_cast( + MF->getSubtarget().getRegisterInfo()); + unsigned SlotSize = RegInfo->getSlotSize(); + for (const MCPhysReg *CSR = MF->getRegInfo().getCalleeSavedRegs(); + unsigned Reg = *CSR; ++CSR) { + if (X86::GR64RegClass.contains(Reg) || X86::GR32RegClass.contains(Reg)) + RestoreBasePointerOffset -= SlotSize; + } + } +} + -- cgit v1.2.3
