I suppose a > clean fix will automatically deal with all of them. Looking at -original it seems that libstdc++ lacks C99 overloads for double - it has them for float and long double only. Or that inline float asinh(float __x) { return __builtin_asinhf(__x); } inline long double asinh(long double __x) { return __builtin_asinhl(__x); } template<typename _Tp> inline typename __gnu_cxx::__enable_if<__is_integer<_Tp>::__value, double>::__type asinh(_Tp __x) { return __builtin_asinh(__x); } isn't constexpr compatible. Doesn't sound like a middle-end issue but either a library or frontend issue to me. That said, it works fine if you give a asinh declaration in the testcase. Richard.
