There are some issues in `llvm-libgcc` before this patch:
Commit c5a20b5182 ([llvm-libgcc] initial
commit)
uses `$<TARGET_OBJECTS:unwind_static>` to get libunwind objects, which
is empty.
The built library is actually a shared version of libclang_rt.builtins.
When configuring with `llvm/CMakeLists.txt`, target `llvm-libgcc`
requires a
corresponding target in `llvm-libgcc/CMakeLists.txt`.
Per target installation is not handled by `llvm-libgcc`, which is not
consistent
with `libunwind`.
This patch fixes those issues by:
Reusing target `unwind_shared` in `libunwind`, linking
`compiler-rt.builtins`
objects into it, and applying version script.
Adding target `llvm-libgcc`, creating symlinks, and utilizing cmake's
dependency
and component mechanism to ensure link targets will be built and
installed along
with symlinks.
Mimicking `libunwind` to handle per target installation.
It is quite hard to set necessary options without further modifying the
order of
runtime projects in `runtimes/CMakeLists.txt`. So though this patch
reveals the
possibility of co-existence of `llvm-libgcc` and
`compiler-rt`/`libunwind` in
`LLVM_ENABLE_RUNTIMES`, we still inhibit it to minimize influence on
other
projects, considering that `llvm-libgcc` is only intended for toolchain
vendors,
and not for casual use.
