From 732eacc0542d0aa48797f675888b85d6065af837 Mon Sep 17 00:00:00 2001 From: Hagen Paul Pfeifer Date: Tue, 26 Oct 2010 14:22:23 -0700 Subject: replace nested max/min macros with {max,min}3 macro Use the new {max,min}3 macros to save some cycles and bytes on the stack. This patch substitutes trivial nested macros with their counterpart.
