From 1aac72d24339380f6e98c50dec4c96ab30537749 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sun, 21 Feb 2010 14:34:33 -0800 Subject: ARM: keep a handle to the PC Keep a handle to the PC in "struct arm", and use it. This register is used a fair amount, so this is a net minor code shrink (other than some line length fixes), but mostly it's to make things more readable. For XScale, fix a dodgy sequence while stepping. It was initializing a variable to a non-NULL value, then updating it to handle the step-over-active-breakpoint case, and then later testing for non-NULL to see if it should reverse that step-over-active logic. It should have done like ARM7/ARM9 does: init to NULL.
