* [ELF] Wrap things in `namespace lld { namespace elf {`, NFCFangrui Song2019-10-071-3/+7
| | | | | | | | | | | This makes it clear `ELF/**/*.cpp` files define things in the `lld::elf` namespace and simplifies `elf::foo` to `foo`. Reviewed By: atanasyan, grimar, ruiu Differential Revision: https://reviews.llvm.org/D68323 llvm-svn: 373885
* [Coding style change] Rename variables so that they start with a lowercase ↵Rui Ueyama2019-07-101-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | letter This patch is mechanically generated by clang-llvm-rename tool that I wrote using Clang Refactoring Engine just for creating this patch. You can see the source code of the tool at https://reviews.llvm.org/D64123. There's no manual post-processing; you can generate the same patch by re-running the tool against lld's code base. Here is the main discussion thread to change the LLVM coding style: https://lists.llvm.org/pipermail/llvm-dev/2019-February/130083.html In the discussion thread, I proposed we use lld as a testbed for variable naming scheme change, and this patch does that. I chose to rename variables so that they are in camelCase, just because that is a minimal change to make variables to start with a lowercase letter. Note to downstream patch maintainers: if you are maintaining a downstream lld repo, just rebasing ahead of this commit would cause massive merge conflicts because this patch essentially changes every line in the lld subdirectory. But there's a remedy. clang-llvm-rename tool is a batch tool, so you can rename variables in your downstream repo with the tool. Given that, here is how to rebase your repo to a commit after the mass renaming: 1. rebase to the commit just before the mass variable renaming, 2. apply the tool to your downstream repo to mass-rename variables locally, and 3. rebase again to the head. Most changes made by the tool should be identical for a downstream repo and for the head, so at the step 3, almost all changes should be merged and disappear. I'd expect that there would be some lines that you need to merge by hand, but that shouldn't be too many. Differential Revision: https://reviews.llvm.org/D64121 llvm-svn: 365595
* [LLD][ELF] - Improve diagnostic about unrecognized relocations.George Rimar2019-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a minor improvement inspired by https://bugs.llvm.org/show_bug.cgi?id=38303. A person reported that he observed message complaining about unsupported R_ARM_V4BX: error: can't create dynamic relocation R_ARM_V4BX against local symbol in readonly segment; recompile object files with -fPIC But with -z notext he only saw a relocation number, what is not convenient: error: ../../gfx/cairo/libpixman/src/pixman-arm-neon-asm-bilinear.o:(.text+0x4F0): unrecognized reloc 40 Also, in the error messages we use relocation but not reloc. With this patch we start to print one of the following messages: error: file.o: unrecognized relocation Unknown(999) error: file.o: unrecognized relocation R_X_KNOWN_BY_LLVM_BUT_UNSUPPORTED_BY_LLD_NAME There is no way to write a test for that I believe.

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636

* [LLD][ELF] - Support MSP430.George Rimar2019-01-101-0/+94
Patch by Michael Skvortsov! This change adds a basic support for linking static MSP430 ELF code. Implemented relocation types are intended to correspond to the BFD. Differential revision: https://reviews.llvm.org/D56535 llvm-svn: 350819
