Are you suggesting that I try to remap them relatively, and if that fails, absolutize it and attempt the remapping again? Or don't absolutize them at all anymore? ================ Comment at: clang/test/Profile/profile-prefix-map.c:12 + +// RUN: %clang_cc1 -fprofile-instrument=clang -fcoverage-mapping -emit-llvm -mllvm -enable-name-compression=false -main-file-name profile-prefix-map.c nested/profile-prefix-map.c -fprofile-prefix-map=%/t/root=. -o - | FileCheck --check-prefix=PROFILE-PREFIX-MAP %s --implicit-check-not=root +// ---------------- rnk wrote: > See here, for example, where you must pass `-fprofile-prefix-map=%/t/...`. +1. I do think I still want this test case, but likely another pending the discussion above that validates the relative path behavior.
