[flang-dev] Code formatting alignment with LLVM

Thu Feb 13 14:58:20 PST 2020

You should also ask the MLIR folks. They use the same clang-format convention as these files.

Hi Johannes,

Hopefully I can clarify: the supposed issue here is that the alignment of the comments on lines 321,322 on the left and 323, 324 on the right have changed, which makes those lines appear as having been changed where they actually haven't other than formatting due to other line changes.

Does that make some sense?

David

I thought we talk about alignment "issues" and this seems not to be one.

Since the discussion there hasn't moved much recently I'd like to start a discussion here so we can get input from a wider group of people.
