From 2948f0cde3974185ad22d6721438cf85df852877 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 15 Jun 2018 14:57:14 +0100 Subject: [PATCH] CODING_STYLE: Define our preferred form for multiline comments The codebase has a bit of a mix of different multiline comment styles. State a preference for the Linux kernel style: /* * Star on the left for each line. * Leading slash-star and trailing star-slash * each go on a line of their own. */ Signed-off-by: Peter Maydell Reviewed-by: Eric Blake Reviewed-by: Cornelia Huck Reviewed-by: Markus Armbruster Reviewed-by: Alex Williamson Reviewed-by: Thomas Huth Reviewed-by: John Snow Reviewed-by: Stefan Hajnoczi Message-id: 20180611141716.3813-1-peter.maydell@linaro.org --- CODING_STYLE | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) diff --git a/CODING_STYLE b/CODING_STYLE index 12ba58ee29..ec075dedc4 100644 --- a/CODING_STYLE +++ b/CODING_STYLE @@ -124,6 +124,23 @@ We use traditional C-style /* */ comments and avoid // comments.
