Then we can find [https://searchfox.org/mozilla-central/source/taskcluster/scripts/misc/build-clang.sh build-clang.sh] - it looks like most of the heavy lifting is done by a script called [https://searchfox.org/mozilla-central/source/build/build-clang/build-clang.py build-clang.py]. We can also find [https://searchfox.org/mozilla-central/source/build/build-clang/clang-linux64.json clang-linux64.json]. Of special note, is that the json file specifies where to find the compiler to compile clang, as well as patches to apply to clang before compiling it. (It might be simpler for you to point the source code fetch to your own repo, rather than adding patches in the json file though.) | Then we can find [https://searchfox.org/mozilla-central/source/taskcluster/scripts/misc/build-clang.sh build-clang.sh] - it looks like most of the heavy lifting is done by a script called [https://searchfox.org/mozilla-central/source/build/build-clang/build-clang.py build-clang.py].
