At the current `main` branch HEAD (commit `14c95e0c8b25f6deba47cd279c5dcdeef3870159`), when running the regression test suite with `ninja check-llvm`, the `ThinLTO/X86/cache.ll` regression test sometimes passes for me, but sometimes fails.
When I run the test with `bin/llvm-lit test/ThinLTO/X86/cache.ll`, it seems to always pass.
I think it failed at different points; but one of the failures was this (failing at the first `; RUN: ls %t.cache.noindex/llvmcache-foo-76` line):
```
