Overall Ack on the whole series once the minor comments are addressed or discussed: Acked-by: Willy Tarreau <w@1wt.eu> thanks! Willy
The current support for LLVM and clang in nolibc and its testsuite is very limited. * Various architectures plain do not compile * The user *has* to specify "-Os" otherwise the program crashes * Cross-compilation of the tests does not work * Using clang is not wired up in run-tests.sh This series extends this support.
