[PATCH 10/12] selftests/nolibc: add cc-option compatible with clang cross builds

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The cc-option macro from Build.include is not compatible with clang
cross builds, as it does not respect the "--target" and similar flags,
set up by Mekfile.include.

Provide a custom variant which works correctly.
