François-Xavier Coudert 0e7e7e6e82 re PR fortran/16580 ([4.1 only] gfortran ICE on test g77.f-torture/execute/intrinsic77.f)
PR fortran/16580
	PR fortran/29288

	* gcc/fortran/intrinsic.c (add_sym): Define the actual_ok when a
	gfc_intrinsic_sym structure is filled.
	(gfc_intrinsic_actual_ok): New function.
	(add_sym_0s, add_sym_1s, add_sym_2s, add_sym_3s, add_sym_4s,
	add_sym_5s): Intrinsic subroutines are not allowed as actual
	arguments, so we remove argument actual_ok.
	(add_functions): Correct the values for actual_ok of all intrinsics.
	(add_subroutines): Remove the actual_ok argument, which was never used.
	* gcc/fortran/intrinsic.h (gfc_intrinsic_actual_ok): New prototype.
	* gcc/fortran/gfortran.h (gfc_resolve_index_func): New prototype.
	* gcc/fortran/resolve.c (resolve_actual_arglist): Check whether
	an intrinsic used as an argument list is allowed there.
	* gcc/fortran/iresolve.c (gfc_resolve_index_func): New function.
	(gfc_resolve_len): Change intrinsic function name to agree with
	libgfortran.
	* gcc/fortran/trans-decl.c (gfc_get_extern_function_decl): Add
	new case, because some specific intrinsics take 3 arguments.
	* gcc/fortran/intrinsic.texi: DIMAG is a GNU extension.

	* libgfortran/Makefile.am: Add the new files to the build
	process, and rules to build them.
	* libgfortran/Makefile.in: Regenerate.
	* libgfortran/m4/misc_specifics.m4: New file.
	* libgfortran/m4/specific.m4: Add new special cases for function
	with complex argument and real result, like abs_c* and aimag_c*.
	* libgfortran/intrinsics/f2c_specifics.F90: Add specifics for
	AIMAG, ASINH, ACOSH and ATANH.
	* libgfortran/generated/_aimag_c4.F90: New file.
	* libgfortran/generated/_aimag_c8.F90: New file.
	* libgfortran/generated/_asinh_r10.F90: New file.
	* libgfortran/generated/_acosh_r16.F90: New file.
	* libgfortran/generated/_aimag_c10.F90: New file.

	* libgfortran/generated/_aimag_c16.F90: New file.
	* libgfortran/generated/_atanh_r10.F90: New file.

	* gcc/testsuite/gfortran.fortran-torture/execute/specifics.f90:
	Add tests for using all possible intrinsics as actual arguments.
	* gcc/testsuite/gfortran.dg/specifics_1.f90: Add tests for using
	all possible intrinsics as actual arguments.
