[Bug fortran/33387] New: Fortran front-end should translate intrinsics by calling C99 function instead of libgfortran functions

[fxcoudert at gcc dot gnu dot org]

Some Fortran intrinsics, like NEAREST or EXPONENT, are translated into calls to
libgfortran functions, which in turn call C99 functions. We could easily
generate C99 calls directly from the front-end, which would enable further
optimization by the middle-end.

The list of intrinsics I think of for which we can do that is: EXPONENT,
FRACTION, NEAREST, RRSPACING, SET_EXPONENT and SPACING.
