2023-02-26rs6000/test: Adjust some test cases on partial vector [PR96373]Kewen Lin15-14/+45
As Richard pointed out in [1] and the testing on Power10, the proposed fix for PR96373 requires some updates on a few rs6000 test cases which adopt partial vector. This patch is to fix all of them with one extra option "-fno-trapping-math" as Richard suggested. Besides, the original test case also failed on Power10 without Richard's proposed fix, this patch adds it together for a bit better testing coverage.

2023-02-22Fortran/OpenMP: Fix mapping of array descriptors and deferred-length stringsTobias Burnus11-125/+1808
Previously, array descriptors might have been mapped as 'alloc' instead of 'to' for 'alloc', not updating the array bounds. The 'alloc' could also appear for 'data exit', failing with a libgomp assert. In some cases, either array descriptors or deferred-length string's length variable was not mapped. And, finally, some offset calculations with array-sections mappings went wrong. The testcases contain some comment-out tests which require follow-up work and for which PR exist. Those mostly relate to deferred-length strings which have several issues beyong OpenMP support.

2023-02-21libstdc++: Fix std::filesystem errors with -fkeep-inline-functions [PR108636]Jonathan Wakely3-8/+23
With -fkeep-inline-functions there are linker errors when including <filesystem>. This happens because there are some filesystem::path constructors defined inline which call non-exported functions defined in the library. That's usually not a problem, because those constructors are only called by code that's also inside the library. But when the header is compiled with -fkeep-inline-functions those inline functions are emitted even though they aren't called. That then creates an undefined reference to the other library internsl. The fix is to just move the private constructors into the library where they are called. That way they are never even seen by users, and so not compiled even if -fkeep-inline-functions is used. libstdc++-v3/ChangeLog: PR libstdc++/108636 * include/bits/fs_path.h (path::path(string_view, _Type)) (path::_Cmpt::_Cmpt(string_view, _Type, size_t)): Move inline definitions to ... * src/c++17/fs_path.cc: ... here. * testsuite/27_io/filesystem/path/108636.cc: New test.

2023-02-20aarch64: Fix up bfmlal lane pattern [PR104921]Alex Coplan4-1/+28
As the testcase shows, this pattern had an incorrect constraint leading to GCC's output getting rejected by the assembler. This patch fixes the constraint accordingly. The test is split into two: one that can run without bf16 support from the assembler and another that checks that the output actually assembles when such support is available. gcc/ChangeLog: PR target/104921 * config/aarch64/aarch64-simd.md (aarch64_bfmlal<bt>_lane<q>v4sf): Use correct constraint for operand 3. gcc/testsuite/ChangeLog: PR target/104921 * gcc.target/aarch64/pr104921-1.c: New test. * gcc.target/aarch64/pr104921-2.c: New test. * gcc.target/aarch64/pr104921.x: Include file for new tests.

2023-02-18LoongArch: Fix multiarch tuple canonizationXi Ruoyao2-8/+8
Multiarch tuple will be coded in file or directory names in multiarch-aware distros, so one ABI should have only one multiarch tuple. For example, "--target=loongarch64-linux-gnu --with-abi=lp64s" and "--target=loongarch64-linux-gnusf" should both set multiarch tuple to "loongarch64-linux-gnusf". Before this commit, "--target=loongarch64-linux-gnu --with-abi=lp64s --disable-multilib" will produce wrong result (loongarch64-linux-gnu). A recent LoongArch psABI revision mandates "loongarch64-linux-gnu" to be used for -mabi=lp64d (instead of "loongarch64-linux-gnuf64") for some non-technical reason [1]. Note that we cannot make "loongarch64-linux-gnuf64" an alias for "loongarch64-linux-gnu" because to implement such an alias, we must create thousands of symlinks in the distro and doing so would be completely unpractical. This commit also aligns GCC with the revision. Tested by building cross compilers with --enable-multiarch and multiple combinations of --target=loongarch64-linux-gnu*, --with-abi=lp64{s,f,d}, and --{enable,disable}-multilib; and run "xgcc --print-multiarch" then manually verify the result with eyesight. [1]: https://github.com/loongson/LoongArch-Documentation/pull/80 gcc/ChangeLog: * config.gcc (triplet_abi): Set its value based on $with_abi, instead of $target. (la_canonical_triplet): Set it after $triplet_abi is set correctly. * config/loongarch/t-linux (MULTILIB_OSDIRNAMES): Make the multiarch tuple for lp64d "loongarch64-linux-gnu" (without "f64" suffix).

2023-02-16Attempt to register OpenMP pinned memory using a device instead of 'mlock'Thomas Schwinge15-19/+460
Implemented for nvptx offloading via 'cuMemHostRegister'. This means: (a) not running into 'mlock' limitations, and (b) the device is aware of this and may optimize host <-> device memory transfers.
