I'm pretty sure it started with this commit:
2003-11-15 Roger Sayle <roger@eyesopen.com>
* include/c_std/std_cmath.h: Don't import C99's float transcendentals
into the __gnu_cxx::__c99_binding namespace.
(acos, asin, atan, atan2, ceil, cosh, exp, floor, fmod, frexp,
ldexp, log, log10, modf, pow, sinh, tan, tanh): Implement using
GCC's math builtins, i.e. __builtin_foo.
* libmath/stubs.c (acosf, acosl, asinf, asinl, atanf, atanl,
ceilf, ceill, floorf, floorl, fmodf, fmodl, frexpf, frexpl,
ldexpf, ldexpl, modff, modfl): Provide stub implementations.
Roger, can you please have a look?
Thanks!
