COFF: Add a new PE/COFF port. This is an initial patch for a section-based COFF linker. The patch has 2300 lines of code including comments and blank lines. Before diving into details, you want to start from reading README because it should give you an overview of the design. All important things are written in the README file, so I write summary here. - The linker is already able to self-link on Windows. - It's significantly faster than the existing implementation. The existing one takes 5 seconds to link LLD on my machine, while the new one only takes 1.2 seconds, even though the new one is not multi-threaded yet. (And a proof-of-concept multi- threaded version was able to link it in 0.5 seconds.) - It uses much less memory (250MB vs. 2GB virtual memory space to self-host). - IMHO the new code is much simpler and easier to read than the existing PE/COFF port. http://reviews.llvm.org/D10036 llvm-svn: 238458

build: add support for standalone lld build Enable building lld as a standalone project. This is motivated by the desire to package lld for inclusion in a linux distribution. This allows building lld against an existing paired llvm installation. Now that lld is usable on x86_64, it makes sense to revive this configuration to allow distributions to package it. llvm-svn: 289421

Set the folder for libraries to 'lld libraries'. NFC. In a UI such as XCode, LLVM source files are in 'libraries' while clang files are in 'clang libraries'. This change moves the lld source to 'lld libraries' to make code browsing easier. It should be NFC as the build itself is still the same, just the structure in a UI differs. llvm-svn: 257001

Chunks.cpp
[LLD][COFF] Early dependency detection We introduce a new class hierarchy for debug types merging (in DebugTypes.h). The end-goal is to parallelize the type merging - please see the plan in D59226. Previously, dependency discovery was done on the fly, much later, during the type merging loop. Unfortunately, parallelizing the type merging requires the dependencies to be merged in first, before any dependent ObjFile, thus this early discovery. The overall intention for this path is to discover debug information dependencies at a much earlier stage, when processing input files. Currently, two types of dependency are supported: PDB type servers (when compiling with MSVC /Zi) and precompiled headers OBJs (when compiling with MSVC /Yc and /Yu). Once discovered, an explicit link is added into the dependent ObjFile, through the new debug types class hierarchy introduced in DebugTypes.h.

refactor COFF linker to use new LTO API Summary: The COFF linker previously implemented link-time optimization using an API which has now been marked as legacy.

COFF: Create a PDB file with the correct file signature. Before this patch, we created an empty PDB file if /debug option is specified. For MSVC linker, such PDB file is completely broken, and linker exits without doing anything as soon as it finds an empty PDB file. A PDB file created in this patch has the correct file signature. MSVC linker still thinks that the file is broken, but it then removes and replaces with its output. This is an initial patch to support PDB in LLD. We aim to support PDB in order to make it 100% compatible with MSVC linker. PDB support is the last missing piece. llvm-svn: 254796

COFF: Implement /linkrepro flag. This flag is implemented similarly to --reproduce in the ELF linker. This patch implements /linkrepro by moving the cpio writer and associated utility functions to lldCore, and using that implementation in both linkers. One COFF-specific detail is that we store the object file from which the resource files were created in our reproducer, rather than the resource files themselves. This allows the reproducer to be used on non-Windows systems for example. Differential Revision: https://reviews.llvm.org/D22418 llvm-svn: 276719

[CMake] Fix pthread handling for out-of-tree builds LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects to correctly link the threading library when needed. Unfortunately `PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed and therefore can't be used when configuring out-of-tree builds. This causes such builds to fail since `pthread` isn't being correctly linked. This patch attempts to fix that problem by renaming and exporting `LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB` because It seemed likely to cause collisions with downstream users of `LLVMConfig.cmake`. llvm-svn: 294690
