[-- Attachment #1: Type: text/plain, Size: 467 bytes --]
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.
