Thanks for working on this.

Looking at some of the red blobs in e.g. the grid view there seem to be
a few failures in the initial "update gcc trunk repo" step of the form:
svn: Working copy '.' locked
svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for
details)
https://gcc-lnt.linki.tools/#/builders/3/builds/388/steps/0/logs/stdio
Is there a bug-tracking location for the buildbot?
Presumably:
https://github.com/LinkiTools/gcc-buildbot/issues
?

I actually found a serious bug in jamais-vu yesterday - it got confused
by multiple .sum lines for the same source line e.g. from multiple
"dg-" directives that all specify a particular line). For example,
when testing one of my patches, of the 3 tests reporting as
"c-c++-common/pr83059.c -std=c++11 (test for warnings, line 7)"
one of the 3 PASS results became a FAIL. jv correctly reported that
new FAILs had occurred, but wouldn't identify them, and mistakenly
reported that new PASSes has occurred also.
I've fixed that now; to do so I've done some refactoring and added a
testsuite.
It looks like you're capturing the textual output from "jv compare" and
using the exit code. Would you prefer to import "jv" as a python
module and use some kind of API? Or a different output format?
If you file pull request(s) for the changes you've made in your copy of
jamais-vu, I can take at look at merging them.
