2025-04-29libstdc++: Fix allocator propagation for rvalue+rvalue string concatenationJonathan Wakely
I made a last-minute change to Nina's r10-200-gf4e678ef74b272 implementation of P1165R1 (consistent allocator propagation for operator+ on strings), so that the rvalue+rvalue case assumes that COW strings do not support stateful allocators. I don't think that was true when the change went in, and isn't true now. COW strings don't support allocator propagation on assignment and swap, but they do support non-equal stateful allocators, which are correctly propagated on move construction. This removes the preprocessor conditional in the rvalue+rvalue overload so that COW strings are handled equivalently. Also use constexpr-if unconditionally, disabling diagnostics with pragmas. libstdc++-v3/ChangeLog: * include/bits/basic_string.h (operator+(string&&, string&&)): Do not assume that COW strings have equal allocators. Use constexpr-if unconditionally. * testsuite/21_strings/basic_string/allocator/char/operator_plus.cc: Remove cxx11_abi effective-target check. * testsuite/21_strings/basic_string/allocator/wchar_t/operator_plus.cc: Likewise.

2024-09-10libstdc++: std::string move assignment should not use POCCA trait [PR116641]Jonathan Wakely
The changes to implement LWG 2579 (r10-327-gdb33efde17932f) made std::string::assign use the propagate_on_container_copy_assignment (POCCA) trait, for consistency with operator=(const basic_string&). However, this also unintentionally affected operator=(basic_string&&) which calls assign(str) to make a deep copy when performing a move is not possible. The fix is for the move assignment operator to call _M_assign(str) instead of assign(str), as this just does the deep copy and doesn't check the POCCA trait first. The bug only affects the unlikely/useless combination of POCCA==true and POCMA==false, but we should fix it for correctness anyway. it should also make move assignment slightly cheaper to compile and execute, because we skip the extra code in assign(const basic_string&). libstdc++-v3/ChangeLog: PR libstdc++/116641 * include/bits/basic_string.h (operator=(basic_string&&)): Call _M_assign instead of assign. * testsuite/21_strings/basic_string/allocator/116641.cc: New test.

2023-02-04libstdc++: Optimize basic_string move assignmentFrançois Dumont
Since resolution of Issue 2593 [1] we can consider that equal allocators before the propagate-on-move-assignment operations will still be equal afterward. So we can extend the optimization of transfering the storage of the move-to instance to the move-from one that is currently limited to always equal allocators. [1] https://cplusplus.github.io/LWG/issue2593 libstdc++-v3/ChangeLog: * include/bits/basic_string.h (operator=(basic_string&&)): Transfer move-to storage to the move-from instance when allocators are equal. * testsuite/21_strings/basic_string/allocator/char/move_assign.cc (test04): New test case.

An effective target like foo-bar-baz will match a target selector of *-*-* and cause problems in the testsuite.
