I just tried reproducing this and it still works fine here (both in vim and in emacs). Are you sure that clang-format removes that trailing whitespace?

Hi Daniel,

I think Rafael is onto something.

If you take a look at r196038 in clang-tools-extra, there's an unrelated whitespace fix that slipped into the commit yesterday:


|@@ -262,7 +262,7 @@ StatementMatcher makePseudoArrayLoopMatcher() {||
|| // Test that the incoming type has a record declaration that has methods|| || // called 'begin' and 'end'. If the incoming type is const, then make sure||

|| // FIXME: To be completely thorough this matcher should also ensure the|| || // return type of begin/end is an iterator that dereferences to the same as|| || // what operator[] or at() returns. Such a test isn't likely to fail except|

The line that was legitimately changed is a fair bit above so I wouldn't have expected to see this edit to an untouched line.

I can try re-creating the patch as it was before running clang-format if it'd be any help.

diff -U0 | clang-format-diff.py -p1 -i

Alp.

    This seems to have caused a regression with at least the emacs

    white space from unrelated areas. For example, run it with the cursor
    in Sema.cpp:1112:

      if (!LangOpts.RetainCommentsFromSystemHeaders &&

    and the trailing white space in Sema.cpp:1100:

    // We have a generic lambda if we parsed auto parameters, or we have

    Cheers,
