- AMD GPU packages: AMD removed support for the RX5x0 GPUs from ROCm, so
I cannot test these packages anymore.
- A small number of GUI packages: I switched back to macOS on the
desktop for work reasons, so I cannot easily test these.
- broot: I took over maintainership from someone else, but do not really
use broot.
llvm/gnu-install-dirs.patch: I've dropped most of the changes to
docs/CMake.rst as they aren't relevant for Nixpkgs and the restructuring
of that file makes it a bit annoying to resolve them via Git.
This also fixes the libunwind build (even with GCC 11 it fails with):
/build/source/libunwind/src/libunwind.cpp:19:5: warning: "__has_feature" is not defined, evaluates to 0 [-Wundef]
19 | #if __has_feature(address_sanitizer)
| ^~~~~~~~~~~~~
/build/source/libunwind/src/libunwind.cpp:19:18: error: missing binary operator before token "("
19 | #if __has_feature(address_sanitizer)
| ^
And the openmp build which failed with this error:

The version will initially remain the same so that no additional changes
to the packaging are required (i.e. this commit only includes the
required changes to build from the mono repository instead of individual
tarballs).
The purpose of this package is to continuously improve the LLVM
packaging in Nixpkgs without causing a lot of rebuilds and provide more
recent LLVM builds for users. For more details see:
https://github.com/NixOS/nixpkgs/issues/114828

The test suite leads to nothing but tears, sorrow, and wasted build
time. It probably should be disabled for all of them but doing only
9 (llvmPackages) and 11 (llvmPackages_latest, Rust) for now. Some of
the failures have been fixed in LLVM main:

- https://reviews.llvm.org/D91043
When using GNU binutils, clang passes the LLVMgold.so plugin to the
linker for certain operations that require special support in the linker
like doing link time optimization (LTO). When passing the plugin to the
linker's command line, clang assumes that llvm and itself are installed
in the same prefix and thus `/path/to/clang/bin/../lib/LLVMgold.so` is
the plugin.
Since we install clang and llvm to separate store paths, this assumption
does not hold. When clang-unwrapped only had a single output, we worked
around this issue by symlinking `$out/lib/LLVMgold.so` to
`${llvm}/lib/LLVMgold.so`. However since we split all llvm packages into
multiple outputs clang's `$out` no longer has a lib directory and clang
can't discover clangs lib output on its own. As a result LTO was broken.
Instead of introducing yet another hack and having a symlink to
LLVMgold.so in `$out/lib` (despite having `$lib/lib` as well), we patch
clang to use a hard coded path to `${libllvm.lib}/lib` for discovering
`LLVMgold.so`.
Resolves#123361.
