Git commit 83ba8addf60668a971453eed207f9bfdaa379f97 by GitHub (on behalf of Andrew Haberlandt) on 20/07/2026 at 17:18..
[compiler-rt] Move sanitizer ignorelists to sanitizer-ignorelists target (#200518)

This adds a `sanitizer-ignorelists` target to compiler-rt, allowing the
ignorelists to be built independently of the sanitizer runtimes. The
ignorelists are still built by default, but this change is not quite
NFC: when any of the sanitizers are built, all of the ignorelists will
be included (rather than the individual runtime ignorelists being built
with their respective runtimes).

For _why_ we want to be able to build these independently of the
runtimes, see
https://github.com/llvm/llvm-project/pull/195690#issuecomment-4384573223

I did not move the dfsan abilist to this new target because it is not as
straightforward as a copying a static file.
