2021-09-06Fortran: Revert to non-multilib-specific ISO_Fortran_binding.hSandra Loosemore6-86/+87
Commit fef67987cf502fe322e92ddce22eea7ac46b4d75 changed the libgfortran build process to generate multilib-specific versions of ISO_Fortran_binding.h from a template, by running gfortran to identify the values of the Fortran kind constants C_LONG_DOUBLE, C_FLOAT128, and C_INT128_T. This caused multiple problems with search paths, both for build-tree testing and installed-tree use, not all of which have been fixed. This patch reverts to a non-multilib-specific .h file that uses GCC's predefined preprocessor symbols to detect the supported types and map them to kind values in the same way as the Fortran front end. 2021-09-06 Sandra Loosemore <sandra@codesourcery.com> libgfortran/ * ISO_Fortran_binding-1-tmpl.h: Deleted. * ISO_Fortran_binding-2-tmpl.h: Deleted. * ISO_Fortran_binding-3-tmpl.h: Deleted. * ISO_Fortran_binding.h: New file to replace the above. * Makefile.am (gfor_cdir): Remove MULTISUBDIR.

2021-09-02libgfortran: Further fixes for GFC/CFI descriptor conversions.Sandra Loosemore2-27/+103
This patch is for: PR100907 - Bind(c): failure handling wide character PR100911 - Bind(c): failure handling C_PTR PR100914 - Bind(c): errors handling complex PR100915 - Bind(c): failure handling C_FUNPTR PR100917 - Bind(c): errors handling long double real All of these problems are related to the GFC descriptors constructed by the Fortran front end containing ambigous or incomplete information. This patch does not attempt to change the GFC data structure or the front end, and only makes the runtime interpret it in more reasonable ways. It's not a complete fix for any of the listed issues. The Fortran front end does not distinguish between C_PTR and C_FUNPTR, mapping both onto BT_VOID. That is what this patch does also. The other bugs are related to GFC descriptors only containing elem_len and not kind. For complex types, the elem_len needs to be divided by 2 and then mapped onto a real kind. On x86 targets, the kind corresponding to C long double is different than its elem_len; since we cannot accurately disambiguate between a 16-byte kind 10 long double from __float128, this patch arbitrarily prefers to interpret that as the standard long double type rather than the GNU extension. Similarly, for character types, the GFC descriptor cannot distinguish between character(kind=c_char, len=4) and character(kind=ucs4, len=1). But since the front end currently rejects anything other than len=1 (PR92482) this patch uses the latter interpretation. 2021-09-01 Sandra Loosemore <sandra@codesourcery.com> José Rui Faustino de Sousa <jrfsousa@gmail.com> gcc/testsuite/ PR fortran/100911 PR fortran/100915 PR fortran/100916 * gfortran.dg/PR100911.c: New file. * gfortran.dg/PR100911.f90: New file. * gfortran.dg/PR100914.c: New file. * gfortran.dg/PR100914.f90: New file. * gfortran.dg/PR100915.c: New file. * gfortran.dg/PR100915.f90: New file. libgfortran/ PR fortran/100907 PR fortran/100911 PR fortran/100914 PR fortran/100915 PR fortran/100917 * ISO_Fortran_binding-1-tmpl.h (CFI_type_cfunptr): Make equivalent to CFI_type_cptr. * runtime/ISO_Fortran_binding.c (cfi_desc_to_gfc_desc): Fix handling of CFI_type_cptr and CFI_type_cfunptr.

2021-08-27libgfortran: Use the libtool macro to determine libm availability.Iain Sandoe5-5/+149
We recently had a report of build failure against a Darwin branch on the latest OS release. This was because (temporarily) the symlink from libm.dylib => libSystem.dylib had been removed/omitted. libm is not needed on Darwin, and should not be added unconditionally even if that is (mostly) harmless since it is a symlink to libc. There could be cases where the addition was not completely harmless because the presentation of the symlink would cause the symbols exposed in libSystem to be considered ahead of ones presented in convenience libraries. libgfortran/ChangeLog: * Makefile.am: Use configured libm availability. * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac: Use libtool macro to find libm availability. * libgfortran.spec.in: Use configured libm availability.

2021-08-10gfortran: Fix in-build-tree testing [PR101305, PR101660]Tobias Burnus2-1/+18
ISO_Fortran_binding.h is written in the build dir - hence, a previous commit added it as include directory for in-build-tree testing. However, it turned out that -I$specdir/libgfortran interferes with reading .mod files as they are then no longer regareded as intrinsic modules. Solution: Create an extra include/ directory in the libgfortran build dir and copy ISO_Fortran_binding.h to that directory. As -B$specdir/libgfortran already causes gfortran to read that include subdirectory, the -I flag is no longer needed.

2021-07-27Bind(c): Improve error checking in CFI_* functionsSandra Loosemore1-116/+168
This patch adds additional run-time checking for invalid arguments to CFI_establish and CFI_setpointer. It also changes existing messages throughout the CFI_* functions to use PRIiPTR to format CFI_index_t values instead of casting them to int and using %d (which may not work on targets where int is a smaller type), simplifies wording of some messages, and fixes issues with capitalization, typos, and the like. Additionally some coding standards problems such as >80 character lines are addressed. 2021-07-24 Sandra Loosemore <sandra@codesourcery.com> PR libfortran/101317 libgfortran/ * runtime/ISO_Fortran_binding.c: Include <inttypes.h>.

2021-07-27Bind(c): Fix bugs in CFI_sectionSandra Loosemore1-17/+10
CFI_section was incorrectly adjusting the base pointer for the result array twice in different ways. It was also overwriting the array dimension info in the result descriptor before computing the base address offset from the source descriptor, which caused problems if the two descriptors are the same. This patch fixes both problems and makes the code simpler, too. A consequence of this patch is that the result array is now 0-based in all dimensions instead of starting at the numbering to match the first element of the source array. The Fortran standard only specifies the shape of the result array, not its lower bounds, so this is permitted and probably less confusing for users as well as implementors. 2021-07-17 Sandra Loosemore <sandra@codesourcery.com> PR libfortran/101310 libgfortran/ * runtime/ISO_Fortran_binding.c (CFI_section): Fix the base address computation and simplify the code. gcc/testsuite/ * gfortran.dg/ISO_Fortran_binding_1.c (section_c): Remove incorrect assertions.

2021-07-27Bind(C): Fix type encodings in ISO_Fortran_binding.hSandra Loosemore7-51/+128
ISO_Fortran_binding.h had many incorrect hardwired kind encodings in the definitions of the CFI_type_* macros. Additionally, not all targets support all the defined type encodings, and the Fortran standard requires those macros to have a negative value. This patch changes ISO_Fortran_binding.h to use sizeof instead of hard-coded sizes, and assembles it from fragments that reflect the set of types supported by the target. 2021-07-22 Sandra Loosemore <sandra@codesourcery.com> Tobias Burnus <tobias@codesourcery.com> libgfortran/ PR libfortran/101305 * ISO_Fortran_binding.h: Fix hard-coded sizes and split into... * ISO_Fortran_binding-1-tmpl.h: New file. * ISO_Fortran_binding-2-tmpl.h: New file. * ISO_Fortran_binding-3-tmpl.h: New file. * Makefile.am: Add rule for generating ISO_Fortran_binding.h.
