Subject: libstdc++: Sync the atomic_link_flags implementation with GCC.
X-Git-Tag: basepoints/gcc-15~597
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=71a44faa8a4f76d68356c66c6054e6c242df820f;p=thirdparty%2Fgcc.git

libstdc++: Sync the atomic_link_flags implementation with GCC.

For Darwin, in order to allow uninstalled testing, we need to provide
a '-B' option pointing to each path containing an uninstalled library
that we are using (these get appended to the embedded runpaths).

This updates the version of the atomic_link_flags proc in the libstdc++
testsuite to do the same as the one in the GCC testsuite.

libstdc++-v3/ChangeLog:

	* testsuite/lib/dg-options.exp (atomic_link_flags): Emit a -B
	option for the path to the uninstalled libatomic.
