From: Patrick Palka <ppalka@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org, libstdc++-cvs@gcc.gnu.org Subject: [gcc r13-7159] libstdc++: Ensure headers used by fast_float are included Date: Wed, 12 Apr 2023 16:40:51 +0000 (GMT) [thread overview] Message-ID: <20230412164051.5C7A1385841D@sourceware.org> (raw) https://gcc.gnu.org/g:13669111e7219ed1f71b2079c7b5794c11f6e3ce commit r13-7159-g13669111e7219ed1f71b2079c7b5794c11f6e3ce Author: Patrick Palka <ppalka@redhat.com> Date: Wed Apr 12 12:40:41 2023 -0400 libstdc++: Ensure headers used by fast_float are included This makes floating_from_chars.cc explicitly include all headers that are used by the original fast_float amalgamation according to r12-6647-gf5c8b82512f9d3, except: 1. <cctype> since fast_float doesn't seem to use anything from it 2. <cinttypes> since fast_float doesn't seem to use anything directly from it (this header also pulls in <cstdint>) 3. <system_error> since std::errc is naturally already available from <charconv> This avoids potential fast_float build failures on platforms for which some required headers (in particular <cstdint>) end up not getting transitively included from elsewhere. libstdc++-v3/ChangeLog: * src/c++17/floating_from_chars.cc: Include <algorithm>, <iterator>, <limits> and <cstdint>.
