PR fortran/33197
gcc/fortran/
* intrinsic.c (add_functions): Modify intrinsics ACOSH, ASINH,
ATANH, ERF, ERFC and GAMMA. Add intrinsics BESSEL_{J,Y}{0,1,N},
ERFC_SCALED, LOG_GAMMA and HYPOT.
* intrinsic.h (gfc_check_hypot, gfc_simplify_hypot,
gfc_resolve_hypot): New prototypes.
* mathbuiltins.def: Add HYPOT builtin. Make complex versions of
ACOSH, ASINH and ATANH available.
* gfortran.h (GFC_ISYM_ERFC_SCALED, GFC_ISYM_HYPOT): New values.
* lang.opt: Add -std=f2008 option.
* libgfortran.h: Define GFC_STD_F2008.
* lang-specs.h: Add .f08 and .F08 file suffixes.
* iresolve.c (gfc_resolve_hypot): New function.
* parse.c (parse_contained): Allow empty CONTAINS for Fortran 2008.
* check.c (gfc_check_hypot): New function.
* trans-intrinsic.c (gfc_intrinsic_map): Define ERFC_SCALE builtin.
* options.c (set_default_std_flags): Allow Fortran 2008 by default.
(form_from_filename): Add .f08 suffix.
(gfc_handle_option): Handle -std=f2008 option.
* simplify.c (gfc_simplify_hypot): New function.
* gfortran.texi: Document Fortran 2008 status and file extensions.
* intrinsic.texi: Document new BESSEL_{J,Y}{0,1,N} intrinsics,
as well as HYPOT and ERFC_SCALED. Update documentation of ERF,
ERFC, GAMMA, LGAMMA, ASINH, ACOSH and ATANH.
* invoke.texi: Document the new -std=f2008 option.
