# ................................................................... # I don't fully understand *why* exactly it is necessary to link against
# Each library name given to the NAMES option is first considered as a library # `gcc_eh`, but when building with `clang` on `aarch64`, *not* linking
# file name and then considered with platform-specific prefixes (e.g. lib) and # against it causes a subtle bug in the `check_index_range` test. Setting
# suffixes (e.g. .so). # a zero value (e.g. `ino.owner_index() = 0;`) will somehow end up with
# ................................................................... # the value *not* being set to zero, but to some other value. Complicating
# the expression (e.g. `ino.owner_index() = ino.owner_index().value() - 0;`)
