The area immediately after the closing right-paren of an if condition should have a count equal to the 'then' block's count. Use a gap region to set this count, so that region highlighting for the 'then' block remains precise. This solves a problem we have with wrapped segments. Consider: 1| if (false) 2| foo(); Without a gap area starting after the condition, the wrapped segment from line 1 would make it look like line 2 is executed, when it's not. rdar://35373009 llvm-svn: 317758
