Status: RESOLVED FIXED

(Firefox Build System :: Toolchains, task)

Attachment: Bug 1751839 - Make most toolchains use a clang-toolchain alias instead of clang/clang-13.

This will allow to decouple the clang toolchain used for toolchain builds
and Firefox.

Attachment: Bug 1751839 - Build clang stage 1 as a separate task.

This allows to start building other toolchains, compiler runtimes, much
earlier, since we don't have to wait for a complete 4-stage-optimized
compiler to start these, while the output produced by clang is
presumably the same whether it's a stage 1 or a stage 4 clang.

We do want to use the llvm-symbolizer from the full clang build, which
has broader binary compatibility and is better guaranteed to match the
compiler used for builds that require llvm-symbolizer.
