This is the s390 counterpart to r11-7364-gd0453cf5c68b6a, and fixes the following names.cc failure caused by a use of a poisoned identifier. If we look at the corresponding upstream header[1] it's clear that the problematic identifier is 'u'.

2025-05-30libstdc++: Move atomic wait/notify entry points into the libraryJonathan Wakely1-2/+0
This moves the implementation details of atomic wait/notify functions into the library, so that only a small API surface is exposed to users. This also fixes some race conditions present in the design for proxied waits: - The stores to _M_ver in __notify_impl must be protected by the mutex, and the loads from _M_ver in __wait_impl and __wait_until_impl to check for changes must also be protected by the mutex. This ensures that checking _M_ver for updates and waiting on the condition_variable happens atomically. Otherwise it's possible to have: _M_ver == old happens-before {++_M_ver; cv.notify;} which happens-before cv.wait. That scenario results in a missed notification, and so the waiting function never wakes. This wasn't a problem for Linux, because the futex wait call re-checks the _M_ver value before sleeping, so the increment cannot interleave between the check and the wait. - The initial load from _M_ver that reads the 'old' value used for the _M_ver == old checks must be done before loading and checking the value of the atomic variable. Otherwise it's possible to have: var.load() == val happens-before {++_M_ver; _M_cv.notify_all();} happens-before {old = _M_ver; lock mutex; if (_M_ver == old) cv.wait}. This results in the waiting thread seeing the already-incremented value of _M_ver and then waiting for it to change again, which doesn't happen. This race was present even for Linux, because using a futex instead of mutex+condvar doesn't prevent the increment from happening before the waiting threads checks for the increment. The first race can be solved locally in the waiting and notifying functions, by acquiring the mutex lock earlier in the function. The second race cannot be fixed locally, because the load of the atomic variable and the check for updates to _M_ver happen in different functions (one in a function template in the headers and one in the library). We do have an _M_old data member in the __wait_args_base struct which was previously only used for non-proxy waits using a futex. We can add a new entry point into the library to look up the waitable state for the address and then load its _M_ver into the _M_old member. This allows the inline function template to ensure that loading _M_ver happens-before testing whether the atomic variable has been changed, so that we can reliably tell if _M_ver changes after we've already tested the atomic variable. This isn't 100% reliable, because _M_ver could be incremented 2^32 times and wrap back to the same value, but that seems unlikely in practice. If/when we support waiting on user-defined predicates (which could execute long enough for _M_ver to wrap) we might want to always wait with a timeout, so that we get a chance to re-check the predicate even in the rare case that _M_ver wraps. Another change is to make the __wait_until_impl function take a __wait_clock_t::duration instead of a __wait_clock_t::time_point, so that the __wait_until_impl function doesn't depend on the symbol name of chrono::steady_clock. Inside the library it can be converted back to a time_point for the clock. This would potentially allow using a different clock, if we made a different __abi_version in the __wait_args imply waiting with a different clock. This also adds a void* to the __wait_args_base structure, so that __wait_impl can store the __waitable_state* in there the first time it's looked up for a given wait, so that it doesn't need to be retrieved again on each loop. This requires passing the __wait_args_base structure by non-const reference. The __waitable_state::_S_track function can be removed now that it's all internal to the library, and namespace-scope RAII types added for locking and tracking contention. libstdc++-v3/ChangeLog: * config/abi/pre/gnu.ver: Add new symbol version and exports. * include/bits/atomic_timed_wait.h (__platform_wait_until): Move to atomic.cc.

2024-07-06libstdc++: Remove redundant 17_intro/headers testsJonathan Wakely35-1278/+26
We have several nearly identical tests under 17_intro/headers which only differ in a -std option set using dg-options. Since the testsuite now supports running tests with multiple -std options (and I test that regularly) we don't need these duplicated tests. We can remove most of them and let the testsuite decide which -std option to use. In the all_attributes.cc case the content of the tests is slightly different, but they can be combined into one test that defines macros conditionally based on __cplusplus checks. The stdc++.cc tests could also be combined this way, but for now I've just kept one version for c++98 and one for all later standards. For stdc++_multiple_inclusion.cc we can remove the body of the files and just include stdc++.cc twice. This means we don't need to add includes to both stdc++.cc and stdc++_multiple_inclusion.cc, we only need to update one place. libstdc++-v3/ChangeLog: * testsuite/17_intro/headers/c++1998/all_attributes.cc: Add attribute names from later standards and remove dg-options. * testsuite/17_intro/headers/c++1998/stdc++.cc: Add c++98_only target selector. * testsuite/17_intro/headers/c++1998/stdc++_multiple_inclusion.cc: Remove content and include stdc++.cc twice instead. * testsuite/17_intro/headers/c++2011/stdc++.cc: Replace dg-options with c++11 target selector. * testsuite/17_intro/headers/c++2011/stdc++_multiple_inclusion.cc: Remove content and include stdc++.cc twice instead. * testsuite/17_intro/headers/c++2011/all_attributes.cc: Removed. * testsuite/17_intro/headers/c++2011/all_no_exceptions.cc: Removed. * testsuite/17_intro/headers/c++2011/all_no_rtti.cc: Removed. * testsuite/17_intro/headers/c++2011/all_pedantic_errors.cc: Removed. * testsuite/17_intro/headers/c++2011/charset.cc: Removed. * testsuite/17_intro/headers/c++2011/operator_names.cc: Removed. * testsuite/17_intro/headers/c++2014/all_attributes.cc: Removed. * testsuite/17_intro/headers/c++2014/all_no_exceptions.cc: Removed. * testsuite/17_intro/headers/c++2014/all_no_rtti.cc: Removed. * testsuite/17_intro/headers/c++2014/all_pedantic_errors.cc: Removed. * testsuite/17_intro/headers/c++2014/charset.cc: Removed. * testsuite/17_intro/headers/c++2014/operator_names.cc: Removed. * testsuite/17_intro/headers/c++2014/stdc++.cc: Removed. * testsuite/17_intro/headers/c++2014/stdc++_multiple_inclusion.cc: Removed. * testsuite/17_intro/headers/c++2017/all_attributes.cc: Removed. * testsuite/17_intro/headers/c++2017/all_no_exceptions.cc: Removed. * testsuite/17_intro/headers/c++2017/all_no_rtti.cc: Removed. * testsuite/17_intro/headers/c++2017/all_pedantic_errors.cc: Removed. * testsuite/17_intro/headers/c++2017/charset.cc: Removed. * testsuite/17_intro/headers/c++2017/operator_names.cc: Removed. * testsuite/17_intro/headers/c++2017/stdc++.cc: Removed. * testsuite/17_intro/headers/c++2017/stdc++_multiple_inclusion.cc: Removed. * testsuite/17_intro/headers/c++2020/all_attributes.cc: Removed. * testsuite/17_intro/headers/c++2020/all_no_exceptions.cc: Removed. * testsuite/17_intro/headers/c++2020/all_no_rtti.cc: Removed. * testsuite/17_intro/headers/c++2020/all_pedantic_errors.cc: Removed. * testsuite/17_intro/headers/c++2020/charset.cc: Removed. * testsuite/17_intro/headers/c++2020/operator_names.cc: Removed. * testsuite/17_intro/headers/c++2020/stdc++.cc: Removed. * testsuite/17_intro/headers/c++2020/stdc++_multiple_inclusion.cc: Removed.

2023-01-27libstdc++: Fix up FAIL in 17_intro/names.cc on glibc < 2.19 [PR108568]Jakub Jelinek1-2/+5
On gcc112 which has glibc 2.17 I've noticed FAIL: 17_intro/names.cc (test for excess errors) FAIL: experimental/names.cc (test for excess errors) These are because glibc < 2.19 used __unused as field member of various structs, including mcontext_t in sys/ucontext.h on ppc64le. This was changed in glibc with https://gcc.gnu.org/pipermail/libc-alpha/2013-November/045766.html names.cc even has #ifdef __GLIBC_PREREQ #if ! __GLIBC_PREREQ(2, 19) // Glibc defines this prior to 2.19 #undef __unused #endif #endif for it, but it doesn't work. The reason is that __GLIBC_PREREQ is defined in <features.h> but nothing included that header before this spot (it is included later from bits/stdc++.h). The following patch on Linux/Hurd conditionally includes features.h to get the needed macros before deciding if __unused should be undefined or not. If needed, I could use __GLIBC_PREREQ then but would need to check if it is defined and between 1996 and 1999 it wasn't. 2023-01-27 Jakub Jelinek <jakub@redhat.com> PR libstdc++/108568 * testsuite/17_intro/names.cc (__unused): For linux or GNU hurd include features.h if present and then check __GLIBC__ and __GLIBC_MINOR__ macros for glibc prior to 2.19, instead of testing __GLIBC_PREREQ which isn't defined yet.

2022-12-06libstdc++: Fix test that fails due to name clash with old glibc [PR107979]Jonathan Wakely1-0/+7
This test was recently modified to check that the library doesn't use __unused anywhere, because that's a macro in newlib. But it's also a macro in old versions of glibc, so the test now fails for those targets. Disable that check for those targets as well as for newlib. libstdc++-v3/ChangeLog: PR libstdc++/107979 * testsuite/17_intro/names.cc: Do not check __unused on old Glibc versions.

2022-11-16libstdc++: Fix stream initialization with static library [PR107701]Patrick Palka1-1/+1
When linking with a static library, the linker seems to discard a constituent .o object (including its global initializers) if nothing defined in the object is referenced by the program (unless e.g. --whole-archive is used). This behavior breaks iostream with static libstdc++.a (on systems that support init priorities) because we define the global initializer for the standard stream objects in a separate TU (ios_init.cc) from the stream object definitions (globals_io.cc). This patch fixes this by moving the stream initialization object into the same TU that defines the stream objects, so that any use of the streams prevents the linker from discarding this global initializer.

2022-05-05libstdc++: Fixes for tests that fail with -fno-rttiJonathan Wakely1-1/+3
This disables a use of dynamic_cast that is not valid for -fno-rtti and adjusts some tests so they don't FAIL with -fno-rtti. Some tests are skipped completely, and others just make use of typeid conditional on the __cpp_rtti macro. A couple of tests were using typeid to verify typedefs denote the right type, which can be done at compile-time using templates instead. libstdc++-v3/ChangeLog: * include/experimental/memory_resource [!__cpp_rtti] (__resource_adaptor_imp::do_is_equal): Do not use dynamic_cast when RTTI is disabled. * testsuite/17_intro/freestanding.cc: Require RTTI. * testsuite/18_support/exception/38732.cc: Likewise. * testsuite/18_support/exception_ptr/rethrow_exception.cc: Likewise. * testsuite/18_support/nested_exception/68139.cc: Likewise. * testsuite/18_support/nested_exception/rethrow_if_nested.cc: Likewise. * testsuite/18_support/type_info/103240.cc: Likewise. * testsuite/18_support/type_info/fundamental.cc: Likewise. * testsuite/18_support/type_info/hash_code.cc: Likewise. * testsuite/20_util/any/assign/emplace.cc: Likewise. * testsuite/20_util/any/cons/in_place.cc: Likewise. * testsuite/20_util/any/misc/any_cast.cc: Likewise. * testsuite/20_util/any/observers/type.cc: Likewise. * testsuite/20_util/function/1.cc: Likewise. * testsuite/20_util/function/2.cc: Likewise. * testsuite/20_util/function/3.cc: Likewise. * testsuite/20_util/function/4.cc: Likewise. * testsuite/20_util/function/5.cc: Likewise. * testsuite/20_util/function/6.cc: Likewise. * testsuite/20_util/function/7.cc: Likewise. * testsuite/20_util/function/8.cc: Likewise. * testsuite/20_util/polymorphic_allocator/resource.cc: Likewise. * testsuite/20_util/shared_ptr/casts/1.cc: Likewise. * testsuite/20_util/shared_ptr/casts/rval.cc: Likewise. * testsuite/20_util/shared_ptr/cons/unique_ptr_deleter_ref_2.cc: Likewise. * testsuite/20_util/shared_ptr/misc/get_deleter.cc: Likewise. * testsuite/20_util/typeindex/comparison_operators.cc: Likewise. * testsuite/20_util/typeindex/comparison_operators_c++20.cc: Likewise. * testsuite/20_util/typeindex/hash.cc: Likewise. * testsuite/20_util/typeindex/hash_code.cc: Likewise. * testsuite/20_util/typeindex/name.cc: Likewise. * testsuite/22_locale/ctype/is/string/89728_neg.cc: Likewise. * testsuite/22_locale/global_templates/standard_facet_hierarchies.cc: Likewise. * testsuite/22_locale/global_templates/user_facet_hierarchies.cc: Likewise. * testsuite/22_locale/locale/13630.cc: Check type without using RTTI. * testsuite/23_containers/array/requirements/non_default_constructible.cc: Require RTTI. * testsuite/27_io/basic_ostream/emit/1.cc: Likewise. * testsuite/27_io/fpos/14320-1.cc: Check type without using RTTI. * testsuite/27_io/fpos/mbstate_t/12065.cc: Require RTTI. * testsuite/27_io/ios_base/failure/dual_abi.cc: Likewise. * testsuite/experimental/any/misc/any_cast.cc: Likewise. * testsuite/experimental/any/observers/type.cc: Likewise. * testsuite/experimental/memory_resource/resource_adaptor.cc: Likewise. * testsuite/lib/libstdc++.exp (check_effective_target_rtti): Define new proc. * testsuite/tr1/3_function_objects/function/1.cc: Likewise. * testsuite/tr1/3_function_objects/function/2.cc: Likewise. * testsuite/tr1/3_function_objects/function/3.cc: Likewise. * testsuite/tr1/3_function_objects/function/4.cc: Likewise. * testsuite/tr1/3_function_objects/function/5.cc: Likewise. * testsuite/tr1/3_function_objects/function/6.cc: Likewise. * testsuite/tr1/3_function_objects/function/7.cc: Likewise. * testsuite/tr1/3_function_objects/function/8.cc: Likewise. * testsuite/tr2/bases/value.cc: Likewise. * testsuite/tr2/direct_bases/value.cc: Likewise. * testsuite/util/exception/safety.h [!__cpp_rtti]: Don't print types without RTTI.

2021-11-10libstdc++: Fix test for libstdc++ not including <unistd.h> [PR100117]Jonathan Wakely1-1/+112
The <cxxx> headers for the C library are not under our control, so we can't prevent them from including <unistd.h>. Change the PR 49745 test to only include the C++ library headers, not the <cxxx> ones. To ensure <bits/stdc++.h> isn't included automatically we need to use no_pch to disable PCH. libstdc++-v3/ChangeLog: PR libstdc++/100117 * testsuite/17_intro/headers/c++1998/49745.cc: Explicitly list all C++ headers instead of including <bits/stdc++.h>
