From df4cf0615f4103b42ca35cacb504126b5f55ac08 Mon Sep 17 00:00:00 2001
From: zwelch <zwelch@b42882b7-edfa-0310-969c-e2dbd0fdcd60>
Date: Sun, 31 May 2009 11:30:59 +0000
Subject: Add target_get_gdb_reg_list wrapper: - replaces all calls to
 target->type->get_gdb_reg_list. - add documentation in target_s to warn not
 to invoke callback directly.
