Remove ability for reserve(n) to reduce a string's capacity. Add a new reserve() overload that makes a shrink-to-fit request, and make shrink_to_fit() use that. libstdc++-v3/ChangeLog: 2020-07-30 Andrew Luo <andrewluotechnologies@outlook.com> Jonathan Wakely <jwakely@redhat.com> * config/abi/pre/gnu.ver (GLIBCXX_3.4): Use less greedy patterns for basic_string members. (GLIBCXX_3.4.29): Export new basic_string::reserve symbols. * doc/xml/manual/status_cxx2020.xml: Update P0966 status. * include/bits/basic_string.h (shrink_to_fit()): Call reserve(). (reserve(size_type)): Remove default argument. (reserve()): Declare new overload. [!_GLIBCXX_USE_CXX11_ABI] (shrink_to_fit, reserve): Likewise. * include/bits/basic_string.tcc (reserve(size_type)): Remove support for shrinking capacity. (reserve()): Perform shrink-to-fit operation. [!_GLIBCXX_USE_CXX11_ABI] (reserve): Likewise. * testsuite/21_strings/basic_string/capacity/1.cc: Adjust to reflect new behavior. * testsuite/21_strings/basic_string/capacity/char/1.cc: Likewise. * testsuite/21_strings/basic_string/capacity/char/18654.cc: Likewise. * testsuite/21_strings/basic_string/capacity/char/2.cc: Likewise. * testsuite/21_strings/basic_string/capacity/wchar_t/1.cc: Likewise. * testsuite/21_strings/basic_string/capacity/wchar_t/18654.cc: Likewise. * testsuite/21_strings/basic_string/capacity/wchar_t/2.cc: Likewise. |
