From bce6c5fd8cc5d3f8d02fd34a24b591fc3e23a775 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Mon, 9 Jan 2006 15:47:04 +1100 Subject: [PATCH] [PATCH] powerpc: DABR exceptions should report the address not the PC When taking a DABR exception we were reporting the PC. It makes more sense to report the address that caused the exception, and the gdb guys would like it that way.
