re PR fortran/33387 (Fortran front-end should translate intrinsics by calling C99 function instead of libgfortran functions)
PR fortran/33387
* trans.h: Remove prototypes for gfor_fndecl_math_exponent4,
gfor_fndecl_math_exponent8, gfor_fndecl_math_exponent10 and
gfor_fndecl_math_exponent16.
* f95-lang.c (build_builtin_fntypes): Add new function types.
(gfc_init_builtin_functions): Add new builtins for nextafter,
frexp, ldexp, fabs, scalbn and inf.
* iresolve.c (gfc_resolve_rrspacing): Don't add hidden arguments.
(gfc_resolve_scale): Don't convert type of second argument.
(gfc_resolve_set_exponent): Likewise.
(gfc_resolve_size): Don't add hidden arguments.
* trans-decl.c: Remove gfor_fndecl_math_exponent4,
gfor_fndecl_math_exponent8, gfor_fndecl_math_exponent10 and
gfor_fndecl_math_exponent16.
* trans-intrinsic.c (gfc_intrinsic_map): Remove intrinsics
for scalbn, fraction, nearest, rrspacing, set_exponent and
spacing.
(gfc_conv_intrinsic_exponent): Directly call frexp.
(gfc_conv_intrinsic_fraction, gfc_conv_intrinsic_nearest,
gfc_conv_intrinsic_spacing, gfc_conv_intrinsic_rrspacing,
gfc_conv_intrinsic_scale, gfc_conv_intrinsic_set_exponent): New
functions.
(gfc_conv_intrinsic_function): Use the new functions above.
