Paul Thomas 0d78e4aa06 re PR fortran/89843 (CFI_section delivers incorrect result descriptor)
2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* trans-decl.c (gfc_get_symbol_decl): Assumed shape and assumed
	rank dummies of bind C procs require deferred initialization.
	(convert_CFI_desc): New procedure to convert incoming CFI
	descriptors to gfc types and back again.
	(gfc_trans_deferred_vars): Call it.
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Null the CFI
	descriptor pointer. Free the descriptor in all cases.

	PR fortran/89846
	* expr.c (is_CFI_desc): New function.
	(is_subref_array): Tidy up by referencing the symbol directly.
	* gfortran.h : Prototype for is_CFI_desc.
	* trans_array.c (get_CFI_desc): New function.
	(gfc_get_array_span, gfc_conv_scalarized_array_ref,
	gfc_conv_array_ref): Use it.
	* trans.c (get_array_span): Extract the span from descriptors
	that are indirect references.

	PR fortran/90022
	* trans-decl.c (gfc_get_symbol_decl): Make sure that the se
	expression is a pointer type before converting it to the symbol
	backend_decl type.
	* trans-expr.c (gfc_conv_gfc_desc_to_cfi_desc): Eliminate
	temporary creation for intent(in).

2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* gfortran.dg/ISO_Fortran_binding_4.f90: Modify the value of x
	in ctg. Test the conversion of the descriptor types in the main
	program.
	* gfortran.dg/ISO_Fortran_binding_10.f90: New test.
	* gfortran.dg/ISO_Fortran_binding_10.c: Called by it.

	PR fortran/89846
	* gfortran.dg/ISO_Fortran_binding_11.f90: New test.
	* gfortran.dg/ISO_Fortran_binding_11.c: Called by it.

	PR fortran/90022
	* gfortran.dg/ISO_Fortran_binding_1.c: Correct the indexing for
	the computation of 'ans'. Also, change the expected results for
	CFI_is_contiguous to comply with standard.
	* gfortran.dg/ISO_Fortran_binding_1.f90: Correct the expected
	results for CFI_is_contiguous to comply with standard.
	* gfortran.dg/ISO_Fortran_binding_9.f90: New test.
	* gfortran.dg/ISO_Fortran_binding_9.c: Called by it.

2019-04-14  Paul Thomas  <pault@gcc.gnu.org>

	PR fortran/89843
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Only
	return immediately if the source pointer is null. Bring
	forward the extraction of the gfc type. Extract the kind so
	that the element size can be correctly computed for sections
	and components of derived type arrays. Remove the free of the
	CFI descriptor since this is now done in trans-expr.c.
	(gfc_desc_to_cfi_desc): Only allocate the CFI descriptor if it
	is not null.
	(CFI_section): Normalise the difference between the upper and
	lower bounds by the stride to correctly calculate the extents
	of the section.

	PR fortran/89846
	* runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Use
	the stride measure for the gfc span if it is not a multiple
	of the element length. Otherwise use the element length.

	PR fortran/90022
	* runtime/ISO_Fortran_binding.c (CFI_is_contiguous) : Return
	1 for true and 0 otherwise to comply with the standard. Correct
	the contiguity check for rank 3 and greater by using the stride
	measure of the lower dimension rather than the element length.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
