commit r17-1915-g4c05f6e10358f379a6da28151b832509f0a3f485 Author: Jonathan Wakely <[email protected]> Date: Fri Jun 26 12:30:57 2026 +0100 libstdc++: Test fs::status and fs::symlink_status with dir symlink I realized that we didn't test that filesystem::status and filesystem::symlink_status work correctly for directory symlinks. For POSIX there's no reason it wouldn't Just Work, but for Windows symlinks to directories and symlinks to regular files require different handling. These tests will ensure that we get it right when Windows symlinks are supported. libstdc++-v3/ChangeLog: * testsuite/27_io/filesystem/operations/status.cc: Check handling of directory symlink. * testsuite/27_io/filesystem/operations/symlink_status.cc: Likewise.
