Subject: libstdc++: Add missing -pthread for new tests [PR122401]
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=935bebb2ce2f9245364cf77bd6804030890f5b62;p=thirdparty%2Fgcc.git

libstdc++: Add missing -pthread for new tests [PR122401]

These new multithreaded tests need -pthread for targets that don't
include all pthreads symbols in libc (including older Glibc in
particular).

The 30_threads/shared_timed_mutex/try_lock_until/116586.cc test is not
fixed by this commit, because it needs a different fix for older Glibc.

libstdc++-v3/ChangeLog:

	PR libstdc++/122401
	* testsuite/20_util/shared_ptr/atomic/pr118757.cc: Add -pthread
	for et pthread.
	* testsuite/20_util/weak_ptr/pr118757.cc: Likewise.
	* testsuite/30_threads/condition_variable/members/116586.cc:
	Likewise. Only run for hosted targets with gthreads support.
	* testsuite/30_threads/future/members/116586.cc: Likewise.
	* testsuite/30_threads/recursive_timed_mutex/try_lock_until/116586.cc:
	Likewise.
	* testsuite/30_threads/timed_mutex/try_lock_until/116586.cc:
	Likewise.
