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/_atanh_r16.F90: New file. * libgfortran/generated/_acosh_r4.F90: New file. * libgfortran/generated/_acosh_r8.F90: New file. * libgfortran/generated/_asinh_r4.F90: New file. * libgfortran/generated/_asinh_r8.F90: New file. * libgfortran/generated/_asinh_r16.F90: New file. * libgfortran/generated/_atanh_r4.F90: New file. * libgfortran/generated/_atanh_r8.F90: New file. * libgfortran/generated/_acosh_r10.F90: New file. * libgfortran/generated/misc_specifics.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. * gcc/testsuite/gfortran.dg/specifics_2.f90: New file. * gcc/testsuite/gfortran.dg/specifics_3.f90: New file.

|
! There are two annoyances WRT the preprocessor:
|
|
! - we're using -traditional-cpp, so we can't use the ## operator.
|
|
! - macros expand to a single line, and Fortran lines can't be wider
|
|
! than 132 characters, therefore we use two macros to split the lines
|
|
!
|
|
! The cases we need to implement are functions returning default REAL
|
|
! or COMPLEX. The former need to return DOUBLE PRECISION instead of REAL,
|
|
! the latter become subroutines returning via a hidden first argument.
