Welcome to the two hundred and sixty-first issue of LLVM Weekly, a weekly
newsletter (published every Monday) covering developments in LLVM, Clang, and
related projects. LLVM Weekly is brought to you by [Alex
Bradbury](https://www.linkedin.com/in/alex-bradbury/). Subscribe to future
issues at <http://llvmweekly.org> and pass it on to anyone else you think may
be interested. Please send any tips or feedback to <asb at asbradbury.org>, or
@llvmweekly or @asbradbury on Twitter.

It's been a very quiet week in LLVM development, no doubt due to the holidays.
Happy New Year!

## News and articles from around the web

Jan Hubička has
his comparison of a GCC vs Clang-compiled Firefox (with LTO+PGO). As with the
previous part, it's incredibly thorough and a fascinating read.

to the 4th Jan, 2019. The workshop will now be taking place on Sunday February

## On the mailing lists

* The PowerPC backend's BitPermutationSelector can now handle ISD::Truncate.

## Clang commits

* The clang-tidy readability-uppercase-literal-suffix check gained an
IgnoreMacros option, enabled by default.

* clang-cl will now treat inputs with `/E` as C++ to match MSVC behaviour.
