From 307ab20b333d9b4c818b1ff912e86944d1a3fdc1 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 19 Feb 2012 15:36:55 -0800 Subject: xdiff: PATIENCE/HISTOGRAM are not independent option bits Because the default Myers, patience and histogram algorithms cannot be in effect at the same time, XDL_PATIENCE_DIFF and XDL_HISTOGRAM_DIFF are not independent bits. Instead of wasting one bit per algorithm, define a few macros to access the few bits they occupy and update the code that access them.
