GCC wrongly accepts [*] in old-style parameter definitions because because parm_flag is set on the scope used for those definitions and, unlike the case of a prototype in a function definition, there is no subsequent check to disallow this invalid usage. This patch adds such a check. (At this point we don't have location information for the [*], so the diagnostic location isn't ideal.) Bootstrapped with no regressions for x86_64-pc-linux-gnu.

This is the equivalent to PR libstdc++/91906, but for shared_mutex. A non-standard clock may tick more slowly than std::chrono::steady_clock. This means that we risk returning false early when the specified timeout may not have expired. This can be avoided by looping until the timeout time as reported by the non-standard clock has been reached. Unfortunately, we have no way to tell whether the non-standard clock ticks more quickly that std::chrono::steady_clock. If it does then we risk returning later than would be expected, but that is unavoidable without waking up periodically to check, which would be rather too expensive. François Dumont pointed out[1] a flaw in an earlier version of this patch that revealed a hole in the test coverage, so I've added a new test that try_lock_until acts as try_lock if the timeout has already expired.

The pthread_rwlock_clockrdlock and pthread_rwlock_clockwrlock functions were added to glibc in v2.30. They have also been added to Android Bionic. If these functions are available in the C library then they can be used to implement shared_timed_mutex::try_lock_until, shared_timed_mutex::try_lock_for, shared_timed_mutex::try_lock_shared_until and shared_timed_mutex::try_lock_shared_for so that they are no longer unaffected by the system clock being warped. (This is the shared_mutex equivalent of PR libstdc++/78237 for mutex.) If the new functions are available then steady_clock is deemed to be the "best" clock available which means that it is used for the relative try_lock_for calls and absolute try_lock_until calls using steady_clock and user-defined clocks. It's not possible to have _GLIBCXX_USE_PTHREAD_RWLOCK_CLOCKLOCK defined without _GLIBCXX_USE_PTHREAD_RWLOCK_T, so the requirement that the clock be the same as condition_variable is maintained. Calls explicitly using system_clock (aka high_resolution_clock) continue to use CLOCK_REALTIME via the old pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock functions. If the new functions are not available then system_clock is deemed to be the "best" clock available which means that the previous suboptimal behaviour remains. Additionally, the user-defined clock used with shared_timed_mutex::try_lock_for and shared_mutex::try_lock_shared_for may have higher precision than __clock_t. We may need to round the duration up to ensure that the timeout is long enough.

The pthread_mutex_clocklock function is available in glibc since the 2.30 release. If this function is available in the C library it can be used to fix PR libstdc++/78237 by supporting steady_clock properly with timed_mutex. This means that code using timed_mutex::try_lock_for or timed_mutex::wait_until with steady_clock is no longer subject to timing out early or potentially waiting for much longer if the system clock is warped at an inopportune moment. If pthread_mutex_clocklock is available then steady_clock is deemed to be the "best" clock available which means that it is used for the relative try_lock_for calls and absolute try_lock_until calls using steady_clock and user-defined clocks.

This patch adds a new target hook to check whether there are any target-specific reasons why a type cannot be used in a certain source-language context. It works in a similar way to existing hooks like TARGET_INVALID_CONVERSION and TARGET_INVALID_UNARY_OP. The reason for adding the hook is to report invalid uses of SVE types. Throughout a TU, the SVE vector and predicate types represent values that can be stored in an SVE vector or predicate register. At certain points in the TU we might be able to generate code that assumes the registers have a particular size, but often we can't. In some cases we might even make multiple different assumptions in the same TU (e.g. when implementing an ifunc for multiple vector lengths). But SVE types themselves are the same type throughout. The register size assumptions change how we generate code, but they don't change the definition of the types. This means that the types do not have a fixed size at the C level even when -msve-vector-bits=N is in effect. It also means that the size does not work in the same way as for C VLAs, where the abstract machine evaluates the size at a particular point and then carries that size forward to later code. The SVE ACLE deals with this by making it invalid to use C and C++ constructs that depend on the size or layout of SVE types. The spec refers to the types as "sizeless" types and defines their semantics as edits to the standards. See: https://gcc.gnu.org/ml/gcc-patches/2018-10/msg00868.html for a fuller description and: https://gcc.gnu.org/ml/gcc/2019-11/msg00088.html for a recent update on the status. However, since all current sizeless types are target-specific built-in types, there's no real reason for the frontends to handle them directly. They can just hand off the checks to target code instead. It's then possible for the errors to refer to "SVE types" rather than "sizeless types", which is likely to be more meaningful to users. There is a slight overlap between the new tests and the ones for gnu_vector_type_p in r277950, but here the emphasis is on testing sizelessness. 2019-11-30 Richard Sandiford <richard.sandiford@arm.com> gcc/ * target.h (type_context_kind): New enum.

Fix an issue with the GCC driver and the `-x' option where a warning is issued in an invocation like: $ riscv64-linux-gnu-gcc -print-multi-directory -x c++ riscv64-linux-gnu-gcc: warning: '-x c++' after last input file has no effect lib64/lp64d $ where no inputs were given and hence the use of `-x' is irrelevant. The statement printed is also untrue as the `-x' does not come after the last input file given that none was given. Do not print it then if no inputs were supplied. * gcc.c (process_command): Only warn about an ineffective `-x' option if any input files have actually been supplied. From-SVN: r278872

The `--enable-version-specific-runtime-libs' configuration option is now supported throughout all of our target library subdirectories, so update installation documentation accordingly and also mention that the default for the option is `yes' for libada and `no' for the remaining libraries. gcc/ * doc/install.texi (Options specification): Remove the list of target library subdirectories supporting `--enable-version-specific-runtime-libs'. Document defaults for the option. From-SVN: r278871

This function failed to compile when called with a std::string. Also, constructing a path with a char8_t string did not correctly treat the string as already UTF-8 encoded. * include/bits/fs_path.h (u8path(InputIterator, InputIterator)) (u8path(const Source&)) [_GLIBCXX_FILESYSTEM_IS_WINDOWS]: Simplify conditions. * include/experimental/bits/fs_path.h [_GLIBCXX_FILESYSTEM_IS_WINDOWS] (__u8path(const Source&, char)): Add overloads for std::string and types convertible to std::string. (_Cvt::_S_wconvert): Add a new overload for char8_t strings and use codecvt_utf8_utf16 to do the correct conversion. From-SVN: r278869
