2020-03-19c++: Fix up handling of captured vars in lambdas in OpenMP clauses [PR93931]Jakub Jelinek2-0/+125
Without the parser.c change we were ICEing on the testcase, because while the uses of the captured vars inside of the constructs were replaced with capture proxy decls, we didn't do that for decls in OpenMP clauses. With that fixed, we don't ICE anymore, but the testcase is miscompiled and FAILs at runtime. This is because the capture proxy decls have DECL_VALUE_EXPR and during gimplification we were gimplifying those to their DECL_VALUE_EXPRs. That is fine for shared vars, but for privatized ones we must not do that. So that is what the cp-gimplify.c changes do. Had to add a DECL_CONTEXT check before calling is_capture_proxy because some VAR_DECLs don't have DECL_CONTEXT set (yet) and is_capture_proxy relies on that being non-NULL always. 2020-03-19 Jakub Jelinek <jakub@redhat.com> PR c++/93931 * parser.c (cp_parser_omp_var_list_no_open): Call process_outer_var_ref on outer_automatic_var_p decls. * cp-gimplify.c (cxx_omp_disregard_value_expr): Return true also for capture proxy decls. * testsuite/libgomp.c++/pr93931.C: New test.

2020-02-13openmp: ignore nowait if async execution is unsupported [PR93481]Frederik Harwath4-13/+15
An OpenMP "nowait" clause on a target construct currently leads to a call to GOMP_OFFLOAD_async_run in the plugin that is used for offloading at execution time. The nvptx plugin contains only a stub of this function that always produces a fatal error if called. This commit changes the "nowait" implementation to ignore the clause if the executing device's plugin does not implement GOMP_OFFLOAD_async_run. The stub in the nvptx plugin is removed which effectively means that programs containing "nowait" can now be executed with nvptx offloading as if the clause had not been used. This behavior is consistent with the OpenMP specification which says that "[...] execution of the target task *may* be deferred" (emphasis added), cf. OpenMP 5.0, page 172. libgomp/ * plugin/plugin-nvptx.c: Remove GOMP_OFFLOAD_async_run stub. * target.c (gomp_load_plugin_for_device): Make "async_run" loading optional.

2020-02-09openmp: Optimize DECL_IN_CONSTANT_POOL vars in target regionsJakub Jelinek2-0/+32
DECL_IN_CONSTANT_POOL are shared and thus don't really get emitted in the BLOCK where they are used, so for OpenMP target regions that have initializers gimplified into copying from them we actually map them at runtime from host to offload devices. This patch instead marks them as "omp declare target", so that they are on the target device from the beginning and don't need to be copied there. 2020-02-09 Jakub Jelinek <jakub@redhat.com> * gimplify.c (gimplify_adjust_omp_clauses_1): Promote DECL_IN_CONSTANT_POOL variables into "omp declare target" to avoid copying them around between host and target. * testsuite/libgomp.c/target-38.c: New test.

This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in.

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.

2019-12-22libgomp/test: Fix compilation for build sysrootMaciej W. Rozycki2-0/+7
Fix a problem with the libgomp testsuite using a method to determine the compiler to use resulting in the tool being different from one the library has been built with, and causing a catastrophic failure from the lack of a suitable `--sysroot=' option where the `--with-build-sysroot=' configuration option has been used to build the compiler resulting in the inability to link executables. Address this problem by defining the compiler to use, via the GCC_UNDER_TEST TCL variable, set in the DejaGNU configuration file from $CC by autoconf, which will have all the required options set for the target compiler to build executables in the environment configured, removing failures like: .../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory .../bin/riscv64-linux-gnu-ld: cannot find -lm .../bin/riscv64-linux-gnu-ld: cannot find -lpthread .../bin/riscv64-linux-gnu-ld: cannot find -lc .../bin/riscv64-linux-gnu-ld: cannot find -latomic collect2: error: ld returned 1 exit status compiler exited with status 1 FAIL: libgomp.c/../libgomp.c-c++-common/atomic-18.c (test for excess errors) Excess errors: .../bin/riscv64-linux-gnu-ld: cannot find crt1.o: No such file or directory .../bin/riscv64-linux-gnu-ld: cannot find -lm .../bin/riscv64-linux-gnu-ld: cannot find -lpthread .../bin/riscv64-linux-gnu-ld: cannot find -lc .../bin/riscv64-linux-gnu-ld: cannot find -latomic UNRESOLVED: libgomp.c/../libgomp.c-c++-common/atomic-18.c compilation failed to produce executable and bringing overall test results for the `riscv64-linux-gnu' target (here with the `x86_64-linux-gnu' host and RISC-V QEMU in the Linux user emulation mode as the target board) from: === libgomp Summary === # of expected passes 44 # of unexpected failures 3274 # of unresolved testcases 3241 # of unsupported tests 548 to: === libgomp Summary === # of expected passes 6834 # of unexpected failures 4 # of expected failures 4 # of unsupported tests 518 libgomp/ * testsuite/libgomp-test-support.exp.in (GCC_UNDER_TEST): New variable.
