Subject: [PATCH 0/6] tools/build: Allow versioning of all LLVM tools
Date: Thu, 14 May 2026 10:32:07 +0100 [thread overview]
Message-ID: <20260514-james-perf-llvm-version-v1-0-6cac1a9a4c8d@linaro.org> (raw)
I ran into the build issue mentioned in the first commit, because using
an option like LLVM=-15 is a documented way to build [1], but only
some of the LLVM tools defined in tools/ support this.
After fixing that, a lot of other tidyups fell out. I didn't go too far,
for example some selftests include tools/testing/selftests/lib.mk which
reimplements some of the LLVM_SUFFIX stuff, but other selftests include
tools/scripts/Makefile.include and I stopped before touching the former.
Some other non build scripts hard code toolchains and I didn't touch
those either, this change is only focused on things that already
include Makefile.include.
