The style guide states that the explicit `inline` should not be used with inline methods. classof is very common inline method with a fair amount on inconsistency: $ git grep classof ./include | grep inline | wc -l 230 $ git grep classof ./include | grep -v inline | wc -l 257 I chose to target this method rather the larger change since this method is easily cargo-culted (I did it at least once). I considered doing the larger change and removing all occurrences but that would be a much larger change. Differential Revision: https://reviews.llvm.org/D33906 llvm-svn: 306731
