I think I've seen a dup.

--- Comment #2 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Heh, I just wanted to push a fix for 'gcc.dg/plugin/diagnostic-test-paths-2.c',
but the cherry-pick from my development branch turned into Git telling me
"nothing to commit": David beat me to it, who included the expected output
update in commit r11-3700-g7345c89ecb1a31ce96c6789bffc7183268a040b3 "Add
-fdiagnostics-path-format=separate-events to -fdiagnostics-plain-output".  ;-)

For reference, this update should've been part of Sandra's commit
r11-3302-g3696a50beeb73f4ded8a584e76ee16f0bde109b9 "Change C front end to emit
structured loop and switch tree nodes".

These FAILs I'm not seeing in my testing.

But this one I still see, too.

Likewise, I'm not seeing those FAILs either.

Likewise; am investigating.

The failure in location-overflow-test-1.c is the subject of pr97117.

Thanks; in that case the only remaining failures are the ones in
gcc.dg/plugin/diagnostic-test-expressions-1.c; are you still seeing those?

No failures in diagnostic-test-expressions-1.c in my latest build (just about
an hour old).  The latest x86_64 result posted to gcc-testresults also looks
clear of plugin test failures except pr97117:

Please feel free to close this.
