[cfe-dev] llvm.org bug trend

[Nikola Smiljanic]

I'd say that bugzilla is in a very sad state. It doesn't seem to be a part
of the development flow (the way commit reviews or tests are). I did some
cleanup a month or two ago, mainly trying to close non issues. Went through
clang Driver and some C++ bugs and found a bunch of bugs that can't be
reproduced. Stuff from gcc stress tests that used to crash but no longer
does. Some bugs are only partially true, like
http://llvm.org/bugs/show_bug.cgi?id=14084, -print-stats is no longer
exposed through the driver but -time is and it doesn't work. It's unclear
if some bugs should be fixed, like
http://llvm.org/bugs/show_bug.cgi?id=6488 (It's
unclear if clang community is interested in supporting this). Some bugs
have attached patches that fix the issue in question, like this one
http://llvm.org/bugs/show_bug.cgi?id=13992 (the comments also tell a
story). And so on...

I would like to see bugzilla cleaned up and bug entry process somewhat
formalized so that entries meet certain quality.
