  Changed paths:

    M clang/lib/Tooling/DependencyScanning/DependencyScanningFilesystem.cpp
    A clang/test/ClangScanDeps/relative-filenames.c

  Log Message:
  -----------
  [DependencyScanningFilesystem] Make sure the local/shared cache filename lookups use only absolute paths (#66122)

Previously a relative path would be used as a key for cache lookup and
if the same relative path was used from another compiler invocation with
a different working directory then the first cache entry was erroneously
returned.
