Subject: libstdc++: Do not optimize away storing pathname if it's needed
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4be7b79d055446a0f647a41ca273ba22a119c7f2;p=test_jj.git

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.

(cherry picked from commit 835b19936bf30d693783bfa39145a4ce243bbd7c)
