  Hello.

By differences about inline function, we can't build simulators on Clang.

I have write after approval permission. Ok to apply this?

The difference is probably that Clang defaults to C99.
You should probably be using CC="clang -std=gnu89".

Patchwise, please try using __attribute__ ((gnu_inline)).

yeah i'm not a fan of sprinkling __clang__ everywhere.  i'm aware that there's 
a bunch of __GNUC__ in there, but those should get cleaned up/centralized 
rather than expanded.  a quick glance shows that there's already cases where 
that can happen (like moving to ATTRIBUTE_NORETURN).
