Fritz Reese e8eecc2a91 Protect the trigd functions in libgfortran from unavailable math functions. 
libgfortran/ChangeLog:

2020-04-22  Fritz Reese  <foreese@gcc.gnu.org>

	PR libfortran/94694
	PR libfortran/94586
	* intrinsics/trigd.c, intrinsics/trigd_lib.inc, intrinsics/trigd.inc:
	Guard against unavailable math functions.
	Use suffixes from kinds.h based on the REAL kind.

gcc/fortran/ChangeLog:

2020-04-22  Fritz Reese  <foreese@gcc.gnu.org>

	* trigd_fe.inc: Use mpfr to compute cosd(30) rather than a host-
	precision floating point literal based on an invalid macro.

gcc/fortran/ChangeLog

	PR fortran/93871
	* gfortran.h (GFC_ISYM_ACOSD, GFC_ISYM_ASIND, GFC_ISYM_ATAN2D,
	GFC_ISYM_ATAND, GFC_ISYM_COSD, GFC_ISYM_COTAND, GFC_ISYM_SIND,
	GFC_ISYM_TAND): New.
	* intrinsic.c (add_functions): Remove check for flag_dec_math.
	Give degree trig functions simplification and name resolution
	functions (e.g, gfc_simplify_atrigd () and gfc_resolve_atrigd ()).
	(do_simplify): Remove special casing of degree trig functions.
	* intrinsic.h (gfc_simplify_acosd, gfc_simplify_asind,
	gfc_simplify_atand, gfc_simplify_cosd, gfc_simplify_cotand,
	gfc_simplify_sind, gfc_simplify_tand, gfc_resolve_trigd2): Add new
	prototypes.
	(gfc_simplify_atrigd, gfc_simplify_trigd, gfc_resolve_cotan,
	resolve_atrigd): Remove prototypes of deleted functions.
	* iresolve.c (is_trig_resolved, copy_replace_function_shallow,
	gfc_resolve_cotan, get_radians, get_degrees, resolve_trig_call,
	gfc_resolve_atrigd, gfc_resolve_atan2d): Delete functions.
	(gfc_resolve_trigd, gfc_resolve_trigd2): Resolve to library functions.
	* simplify.c (rad2deg, deg2rad, gfc_simplify_acosd, gfc_simplify_asind,
	gfc_simplify_atand, gfc_simplify_atan2d, gfc_simplify_cosd,
	gfc_simplify_sind, gfc_simplify_tand, gfc_simplify_cotand): New
	functions.
	(gfc_simplify_atan2): Fix error message.
	(simplify_trig_call, gfc_simplify_trigd, gfc_simplify_atrigd,
	radians_f): Delete functions.
	* trans-intrinsic.c: Add LIB_FUNCTION decls for sind, cosd, tand.
	(rad2deg, gfc_conv_intrinsic_atrigd, gfc_conv_intrinsic_cotan,
	gfc_conv_intrinsic_cotand, gfc_conv_intrinsic_atan2d): New functions.
	(gfc_conv_intrinsic_function): Handle ACOSD, ASIND, ATAND, COTAN,
	COTAND, ATAN2D.
	* trigd_fe.inc: New file. Included by simplify.c to implement
	simplify_sind, simplify_cosd, simplify_tand with code common to the
	libgfortran implementation.

gcc/testsuite/ChangeLog

	PR fortran/93871
	* gfortran.dg/dec_math.f90: Extend coverage to real(10) and real(16).
