Does anyone know anything about these failures that I see on my aarch64
build & test?
FAIL: gcc.dg/tree-ssa/pr77445-2.c scan-tree-dump-not thread3 "not considered"
FAIL: gcc.dg/tree-ssa/ssa-dom-thread-7.c scan-tree-dump-not vrp2 "Jumps threaded"
The both seem to have started showing up on May 20th and I don't see any
bugzilla report on them. Before I try and track down what checkin caused
them and whether or not they were caused by the same checkin I thought I
would see if anyone had already done that.

Yes it's sometimes tricky to find out if a regression has been reported or not.
Martin is aware of these two:
