git submodule update --init fails
For some reason, git submodule update --init
fails.
fatal: reference is not a tree: c8a8767c56ad3d3f4eb45c87b95026936fb9aa35
Unable to checkout 'c8a8767c56ad3d3f4eb45c87b95026936fb9aa35' in submodule path 'profiler-rt/compiler-rt'
I guess something got deleted from the repo being pulled from?
Yeah, a lot has changed since last time I touched this. For example, rust toolchain now includes its own profiler runtime (albeit guarded by a feature flag), so building profiler-rt might not be necessary. I didn't have the time lately to explore new developments.
