I thought it was OK/useful as it was, but I don't mind either way.
BTW, while trying it out locally, I noticed:
aarch64_init_data_intrinsics
was called from the wrong place. Since it's adding normal __builtin
functions, it should be called from aarch64_general_init_builtins
instead of handle_arm_acle_h.
handle_arm_acle_h is instead for cases where we want to simulate
C/C++ definitions of the ACLE intrinsics themselves (i.e. so that
the intrinsics themselves are built-in functions, rather than
inline wrappers around built-in functions).
OK with that change, thanks.
Thanks,
Richard
