We want lld-link to automatically find compiler-rt's and libc++ when it's in the same directory as the rest of the toolchain. This is because on Windows linking isn't done via the clang driver - but instead invoked directly. This prepends: <llvm>/lib <llvm>/lib/clang/XX/lib and <llvm>/lib/clang/XX/lib/windows automatically to the library search paths.

Breaking changes
|
|
----------------
|
|
|
|
COFF Improvements
|
|
-----------------
|
|
|
|
* lld-link can now find libraries with relative paths that are relative to
|
|
`/libpath`. Before it would only be able to find libraries relative to the
|
|
current directory.
|
|
I.e. ``lld-link /libpath:c:\relative\root relative\path\my.lib`` where before
|
|
we would have to do ``lld-link /libpath:c:\relative\root\relative\path my.lib``
|
|
* lld-link learned -print-search-paths that will print all the paths where it will
|
|
search for libraries.
|
|
* By default lld-link will now search for libraries in the toolchain directories.
|
|
Specifically it will search:
|
|
``<toolchain>/lib``, ``<toolchain>/lib/clang/<version>/lib`` and
|
|
``<toolchain>/lib/clang/<version>/lib/windows``.
