--- Comment #2 from Steven Munroe <munroesj at us dot ibm.com> --- Well the language spec may not specify. But I can ask the platform to be consistent with itself. For PowerISA I would expect long double -> __int128 to be consistent with double -> long, which saturates (INT_MAX). Also the current fixtfti implementation is very slow. So while this may not be a general GCC (libgcc) bug. I don't think anyone would mind if the PowerPC platform optimized this function and made its behavour consistent with the PowerISA.
