From 7e5b59384eebe35bff8429243f089931ce1cdf38 Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Wed, 8 Mar 2006 20:40:28 +0100 Subject: [PATCH] powerpc: add a raw dump command to xmon Dump a stream of rawbytes with a new 'dr' command. Produces less output and it is simpler to feed the output to scripts. Also, dr has no dumpsize limits.
