2021-08-23openmp: Add support for strict modifier on grainsize/num_tasks clausesJakub Jelinek1-0/+1
With strict: modifier on these clauses, the standard is explicit about how many iterations (and which) each generated task of taskloop directive should contain. For num_tasks it actually matches what we were already implementing, but for grainsize it does not (and even violates the old rule - without strict it requires that the number of iterations (unspecified which exactly) handled by each generated task is >= grainsize argument and < 2 * grainsize argument, with strict: it requires that each generated task handles exactly == grainsize argument iterations, except for the generated task handling the last iteration which can handles <= grainsize iterations). The following patch implements it for C and C++. 2021-08-23 Jakub Jelinek <jakub@redhat.com> gcc/ * tree.h (OMP_CLAUSE_GRAINSIZE_STRICT): Define.

2021-07-24include: Fix -Wundef warnings in ansidecl.hMarek Polacek1-3/+3
This quashes -Wundef warnings in ansidecl.h when compiled in C or C++. In C, __cpp_constexpr and __cplusplus aren't defined so we evaluate them to 0; conversely, __STDC_VERSION__ is not defined in C++. This has caused grief when -Wundef is used with -Werror. I've also tested -traditional-cpp. include/ChangeLog: * ansidecl.h: Check if __cplusplus is defined before checking the value of __cpp_constexpr and __cplusplus. Don't check __STDC_VERSION__ in C++.

2021-07-02BTF: Support for BTF_KIND_FLOATDavid Faust1-4/+5
Add BTF_KIND_FLOAT, a new BTF type kind which has recently stabilized in the linux kernel [1]. This kind is used for encoding floating point types, and is of particular use when generating BTF for some s390 arch-specific kernel headers. Also update some BTF tests which previously used floating point types to check correct behavior for types with no BTF representation.

2021-05-06libiberty: add htab_eq_stringTom Tromey1-0/+3
The libiberty hash table includes a helper function for strings, but no equality function. Consequently, this equality function has been reimplemented a number of times in both the gcc and binutils-gdb source trees. This patch adds the function to the libiberty hash table, as a step toward the goal of removing all the copies. One change to gcc is included here. Normally I would have put this in the next patch, but gensupport.c used the most natural name for its reimplementation of this function, and this can't coexist with the extern function in libiberty. include * hashtab.h (htab_eq_string): Declare. libiberty * hashtab.c (htab_eq_string): New function. gcc * gensupport.c (htab_eq_string): Remove.

2021-03-30c++: Adjust mangling of __alignof__ [PR88115]Patrick Palka1-0/+3
r11-4926 made __alignof__ get mangled differently from alignof, encoding __alignof__ as a vendor extended operator. But this mangling is problematic for the reasons mentioned in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88115#c6. This patch changes our mangling of __alignof__ to instead use the new "vendor extended expression" syntax that's proposed in https://github.com/itanium-cxx-abi/cxx-abi/issues/112. Clang does the same thing already, so after this patch Clang and GCC agree about the mangling of __alignof__(type) and __alignof__(expr). gcc/cp/ChangeLog: PR c++/88115 * mangle.c (write_expression): Adjust the mangling of __alignof__. include/ChangeLog: PR c++/88115 * demangle.h (enum demangle_component_type): Add DEMANGLE_COMPONENT_VENDOR_EXPR. libiberty/ChangeLog: PR c++/88115 * cp-demangle.c (d_dump, d_make_comp, d_expression_1) (d_count_templates_scopes): Handle DEMANGLE_COMPONENT_VENDOR_EXPR.

2020-08-03Removal of HSA offloading from gcc and libgompMartin Jambor1-1/+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.

2019-12-22Add OpenACC 2.6 `acc_get_property' supportMaciej W. Rozycki2-0/+21
Add generic support for the OpenACC 2.6 `acc_get_property' and `acc_get_property_string' routines, as well as full handlers for the host and the NVPTX offload targets and minimal handlers for the HSA, Intel MIC, and AMD GCN offload targets. Included are C/C++ and Fortran tests that, in particular, print the property values for acc_property_vendor, acc_property_memory, acc_property_free_memory, acc_property_name, and acc_property_driver. The output looks as follows: Vendor: GNU Name: GOMP Total memory: 0 Free memory: 0 Driver: 1.0 with the host driver (where the memory related properties are not supported for the host device and yield 0, conforming to the standard) and output like: Vendor: Nvidia Total memory: 12651462656 Free memory: 12202737664 Name: TITAN V Driver: CUDA Driver 9.1 with the NVPTX driver. 2019-12-22 Maciej W.
