# As of 0.5.0 release both arm failed to build on gcc due to a lot of issues like:
#error: undefined reference to 'checkasm_fail_func'
#/src/arm/64/ipred.S:876: error: undefined reference to 'dav1d_sm_weights'
# Using clang gives, error: unknown directive .endfunc
#<instantiation>:55:1: note: while in macro instantiation endfunc
# Solution is disable LTO and use Clanh for ARM.
#--
#ARM use GCC because Clang failed to build.
