As noted in PR 96817 this new test fails if the library is built without futexes. That's expected of course, but we might as well fail more obviously than a deadlock that eventually times out. libstdc++-v3/ChangeLog: * testsuite/18_support/96817.cc: Fail fail if the library is configured to not use futexes. Tested powerpc64le-linux. Committed to trunk. I've just realised the changelog above should say "Fail fast", I'll fix that in the ChangeLog tomorrow. commit 9c1125c121423a9948fa39e71ef89ba4059a2fad Author: Jonathan Wakely <jwakely@redhat.com> Date: Wed Nov 4 15:24:47 2020 libstdc++: Fix test failure with --disable-linux-futex As noted in PR 96817 this new test fails if the library is built without futexes.
