There’s a whole set of cases where it makes unwelcome changes to put things that were on separate lines on a single line. Whenever I run clang-format, I typically git checkout -p to discard all of these.</div><div class=""><br class=""></div><div class="">For example, it likes to take member initializer lists and pack them into as few lines as possible. This is just asking for merge conflicts (e.g. AMDGPUSubtarget has a ton of fields in it, and out of tree code is constantly adding new fields for unreleased subtargets). It also mangles BuildMI calls, where I believe every .add() should be on its own line, and stringing this into BuildMI().addFoo().addBar() is way less readable.</div><div class=""><br class=""></div><div class="">I also believe it’s 4 space indent on line wraps differs from the stated 2 space indent level (and this also disagrees with emacs llvm-style)</div><div class=""><br class=""></div><div class="">-Matt</div></body></html>
