One more question: why do we explicitely call the builtin via an inline instead of letting gcc do this?
here's an example from the i386 header: #if __GNUC_PREREQ (3, 4) __inline_mathcodeNP2_ (long double, __atan2l, __y, __x, return __builtin_atan2l (__y, __x))
Since this refers to __atan2l, maybe it's about mapping __atan2l to the built-in function (whereas GCC would only do that for atan2l, not __atan2l)? Though that's hardly relevant unless __atan2l is used in other inlines or within glibc.
