Hi ,
we tried to compile the audio decoder lib with clang like
https://github.com/markjeee/libmad with overriding the CFLAGS with llvm
internal option like
export CFLAGS="-O3 clang -mllvm -inline-threshold=1000 -mllvm
-enable-loop-distribute test.c " ,here tool sorts the options before giving
to driver and options ends up option like "-O3 -mllvm -mllvm
-enable-loop-distribute -inline-threshold=1000 "
hence the clang driver errors out like
clang: error: unknown argument '-inline-recursion=2'; did you mean
'-finline-recursion=2'?
which is expected ,since the clang driver expect all internal options prepend
with "-mllvm".
Please let us know ,if required more info on this ,
thank you
