llvm dev - Dec 2016 - Call for testing/heads-up: NewGVN

Hi everybody.
NewGVN was recently committed and a few minute ago I added a flag to
enable the new experimental pass.

For the brave soul, passing `-mllvm -enable-newgvn` should do the
trick. We'll be happy to receive bug reports to analyze/fix, bonus
point if they contain a synthetic/reduced testcase.
Open a bug linked to https://llvm.org/bugs/show_bug.cgi?id=30995 would
be probably best so that all the people working on NewGVN will have
visibility, but I'm aware there are issues with bugzilla registration
disabled recently so if you have issues/don't have an account feel
free to shoot me a mail directly and I'll open a bug on your behalf.

Looking forward to hearing from you,

--

Note:
I just fixed a significant bug accidentally ported from the branch, so make
your llvm is synced past r290549 before you give this a try.

Hi,

I’m curious if the test-suite running cleanly with this flag?
(That would be a first step before wider testing).

Thanks,

Also: does clang bootstrap and pass the tests (and builds the test-suite
correctly?).
