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/AVR/AVRTargetObjectFile.cpp | 40 ++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 contrib/llvm-project/llvm/lib/Target/AVR/AVRTargetObjectFile.cpp (limited to 'contrib/llvm-project/llvm/lib/Target/AVR/AVRTargetObjectFile.cpp') diff --git a/contrib/llvm-project/llvm/lib/Target/AVR/AVRTargetObjectFile.cpp b/contrib/llvm-project/llvm/lib/Target/AVR/AVRTargetObjectFile.cpp new file mode 100644 index 000000000000..980096a09835 --- /dev/null +++ b/contrib/llvm-project/llvm/lib/Target/AVR/AVRTargetObjectFile.cpp @@ -0,0 +1,40 @@ +//===-- AVRTargetObjectFile.cpp - AVR Object Files ------------------------===// +// +// 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 "AVRTargetObjectFile.h" + +#include "llvm/BinaryFormat/ELF.h" +#include "llvm/IR/DerivedTypes.h" +#include "llvm/IR/GlobalValue.h" +#include "llvm/IR/Mangler.h" +#include "llvm/MC/MCContext.h" +#include "llvm/MC/MCSectionELF.h" + +#include "AVR.h" + +namespace llvm { +void AVRTargetObjectFile::Initialize(MCContext &Ctx, const TargetMachine &TM) { + Base::Initialize(Ctx, TM); + ProgmemDataSection = + Ctx.getELFSection(".progmem.data", ELF::SHT_PROGBITS, ELF::SHF_ALLOC); +} + +MCSection * +AVRTargetObjectFile::SelectSectionForGlobal(const GlobalObject *GO, + SectionKind Kind, + const TargetMachine &TM) const { + // Global values in flash memory are placed in the progmem.data section + // unless they already have a user assigned section. + if (AVR::isProgramMemoryAddress(GO) && !GO->hasSection()) + return ProgmemDataSection; + + // Otherwise, we work the same way as ELF. + return Base::SelectSectionForGlobal(GO, Kind, TM); +} +} // end of namespace llvm + -- cgit v1.2.3
