--- Comment #7 from Uroš Bizjak <ubizjak at gmail dot com> --- The difference si that the call to f128_p3 does not expand with "use (reg:SI bx)" tag in the Darwin case. Probably ix86_expand_call should be fixed for TARGET_MACHO. However, even if this will solve bootstrap, the RA should be fixed to mark PIC register live in case when constant is moved to memory.
