2020-08-17openacc: No attach/detach present/release mappings for array descriptorsJulian Brown1-17/+27
Standalone attach and detach clauses should not create present/release mappings for Fortran array descriptors (e.g. used when we have a pointer to an array), both because it is unnecessary and because those mappings will be incorrectly subject to reference counting. Simply omitting the mappings means we just use GOMP_MAP_TO_PSET and GOMP_MAP_{ATTACH,DETACH} mappings for array descriptors. That requires a tweak in gimplify.c, since we may now see GOMP_MAP_TO_PSET without a preceding data-movement mapping. 2020-08-03 Julian Brown <julian@codesourcery.com> Thomas Schwinge <thomas@codesourcery.com> gcc/fortran/ * trans-openmp.c (gfc_trans_omp_clauses): Don't create present/release mappings for array descriptors. gcc/ * gimplify.c (gimplify_omp_target_update): Allow GOMP_MAP_TO_PSET without a preceding data-movement mapping. gcc/testsuite/ * gfortran.dg/goacc/attach-descriptor.f90: Update pattern output.

2020-08-17Removal of HSA offloading from gcc and libgompMartin Jambor1-11/+0
This patch removes the generation of HSAIL from the compiler, the HSA offloading plugin from libgomp and the associated testsuite tests and infrastructure bits from the respective testsuites. Apart from removal of the obvious files, I removed bits that I found by searching for HSA related terms and by re-tracing my steps and looking at the patches that introduced HSA in the first place. I did not remove everything these patches brought in, for example: - the mechanism to pass offload-target specific info from the application to the offloading plugin - but the same mechanism is also used to communicate number of teams and the thread limit to all offload targets. - run_func hook in gomp_device_descr stays too, although now it is not used. If some future offload target would like the ability to refuse to offload some functions, it can use it. It is easy to remove as a follow-up if it is considered clutter, though. - configure options --with-hsa-runtime=PATH, -with-hsa-runtime-include=PATH and --with-hsa-runtime-lib=PATH rmeain because GCN uses them too. - Surprisingly, GOMP_TARGET_ARG_HSA_KERNEL_ATTRIBUTES (a constant from gomp-constants.h) appears in the source of the amdgcn libgomp plugin, although I tend to think that code path is not ever used and this patch certainly removes it from the compiler. Nevertheless, it seems it has potential value beyond HSAIL and so I've kept it, it can of course always be easily removed in the future of GCN folk abandon it too. - I assume constants OFFLOAD_TARGET_TYPE_HSA and GOMP_DEVICE_HSA need to stay indefinitely too just so that no future offload target picks that number. - I have kept dg-require-effective-target offload_device_nonshared_as requirement of thests which have it. It is quite probable I missed some small HSA artifacts but those should be easy to remove later as we find them. include/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * gomp-constants.h (GOMP_VERSION_HSA): Remove. gcc/ChangeLog: 2020-07-24 Martin Jambor <mjambor@suse.cz> * hsa-brig-format.h: Moved to brig/brigfrontend. * hsa-brig.c: Removed. * hsa-builtins.def: Likewise. * hsa-common.c: Likewise. * hsa-common.h: Likewise. * hsa-dump.c: Likewise. * hsa-gen.c: Likewise. * hsa-regalloc.c: Likewise. * ipa-hsa.c: Likewise. * omp-grid.c: Likewise. * omp-grid.h: Likewise. * Makefile.in (BUILTINS_DEF): Remove hsa-builtins.def.

2020-08-17Always use name from c_interop_kinds_table for -fc-prototypes.Thomas Koenig1-36/+19
When a user specified a KIND that was a parameter taking the value of an iso_c_binding KIND, the code used the name of that parameter to look up the type name. Corrected by always looking it up in the table of C interop kinds (which was previously done for non-C-interop types, anyway). gcc/fortran/ChangeLog: PR fortran/96220 * dump-parse-tree.c (get_c_type_name): Always use the entries from c_interop_kinds_table to find the correct C type.
2020-08-17Fix handling of implicit_pure by checking if non-pure procedures are called.Thomas Koenig3-1/+98
Procedures are marked as implicit_pure if they fulfill the criteria of pure procedures. In this case, a procedure was not marked as not being implicit_pure which called another procedure, which had not yet been marked as not being implicit_impure. Fixed by iterating over all procedures, setting callers of procedures which are non-pure and non-implicit_pure as non-implicit_pure and doing this until no more procedure has been changed. gcc/fortran/ChangeLog: 2020-07-19 Thomas Koenig <tkoenig@gcc.gnu.org> PR fortran/96018 * frontend-passes.c (gfc_check_externals): Adjust formatting. (implicit_pure_call): New function. (implicit_pure_expr): New function. (gfc_fix_implicit_pure): New function. * gfortran.h (gfc_fix_implicit_pure): New prototype. * parse.c (translate_all_program_units): Call gfc_fix_implicit_pure.

2020-08-17fortran: Restore translation to hint.David Edelsohn1-1/+1
This patch restore translation for the variable hint. The translation tag conflicted with the previous declaration of hint as char[] and broke bootstrap, so the translation tags were removed. The declaration was changed to char *. This patch restores the translation tags to the string. gcc/fortran/ChangeLog 2020-07-18 David Edelsohn <dje.gcc@gmail.com> * check.c (gfc_invalid_boz): Mark hint for translation using _().
