# 1. The absolute paths of binaries used in tests are resolved in configure phase.

|
# which is always placed before `${clang-tools}/bin` in PATH. `clang-tidy` provided in
|
|
# `clang-unwrapped` cause tests failing because it is not wrapped to resolve header search paths.

# As a temporary fix, we disabled these tests when using clang stdenv
