From 4be7b79d055446a0f647a41ca273ba22a119c7f2 Mon Sep 17 00:00:00 2001 From: Jonathan Wakely Date: Tue, 28 Jun 2022 09:26:12 +0100 Subject: [PATCH] libstdc++: Do not optimize away storing pathname if it's needed libstdc++-v3/ChangeLog: * src/c++17/fs_dir.cc (_Dir::_Dir) [!_GLIBCXX_HAVE_OPENAT]: Always store pathname if we don't have openat or unlinkat, because the full path is needed to open sub-directories and remove entries.
