Rui Ueyama 3f851704c1 Move new lld's code to Common subdirectory.
New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.

Martell Malone 894dbbe8eb LLD: Introduce a GNU LD style driver for COFF
When building COFF programs many targets such as mingw prefer
to have a gnu ld frontend. Rather then having a fully fledged
standalone driver we wrap a shim around the LINK driver.

Extra tests were provided by mstorsjo

Michal Gorny da7ceb5e1b [cmake] Support running tests in stand-alone builds
Add the CMake bits necessary to run lld tests (and unittests) when
building stand-alone. The code is based on the equivalent code in clang,
and includes:

1. checking for Python, searching for lit and necessary LLVM test tools
(FileCount and not),

2. building LLVM test tools (FileCount and not) from LLVM sources if
they are not installed,

3. building gtest libraries from LLVM sources,

4. adjusting dependencies so that test targets depend only on those LLVM
targets that are available for a particular variant of stand-alone
build.

With this patch, I am able to successfully run 1002 (+10 unsupported)
lit tests on Gentoo using installed LLVM.

Michal Gorny 30dc91a707 [cmake] Fix -rpath-link in stand-alone build
Set LLVM_LIBRARY_OUTPUT_INTDIR as expected by llvm_setup_rpath() macro
when doing stand-alone builds. This is required to pass correct
-rpath-link when linking shared libraries, and therefore ensure that
the linker can find dependency libraries correctly during the build.

Petr Hosek f367a2a52b [CMake] Add install target for the lld tool
This is necessary for the distribution targets which assume that
each component has an install target. This also moves the CMake
macros into a separate file akin to other LLVM projects.

Saleem Abdulrasool f1af26ddf2 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.

Pete Cooper 69b18f4703 Set CMake ADDITIONAL_HEADER_DIRS on libraries with headers in /include. NFC.
In a UI such as XCode, it can group the headers for a library with that library.
This is done in the CMakeLists.txt for the library itself by setting the path(s)
as ADDITIONAL_HEADER_DIRS.

LLVM already does this for all of its libraries, so just adding this to lld to
make things easier.  Should be NFC.

Pete Cooper f154b678c6 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.

Rui Ueyama 411c636081 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.

Chandler Carruth 5ad16c2ad0 Move the 'linker-script-test' binary to the tools directory.
The canonical LLVM directory arrangement places binaries in the 'utils/'
tree when they are used as part of building the project. For example,
the tblgen binaries are built out of 'utils/' trees.

Tools which are not used by any other part of the build, including
testing utilities, are just in the 'tools' directory. For example, in
Clang we have 'c-index-test' which is exactly the same kind of thing as
'linker-script-test'.

Hans Wennborg 306db8f3fa CMake: Don't look for llvm-tblgen when building outside LLVM tree
Previously, the CMake build would look for llvm-tblgen to determine
if a directory is an LLVM build or install directory. Since we don't
want to include llvm-tblgen in the install, look for llvm-config instead,
and use that to find llvm-tblgen.

(This is the lld equivalent of Clang r189127.)
