From 83c31e7d1e6077d2802d8906453622471b72de8d Mon Sep 17 00:00:00 2001
From: Fernando Nasser <fnasser@redhat.com>
Date: Fri, 8 Nov 2002 03:21:34 +0000
Subject: 	* printcmd.c (disassemble_command): Remove obsolete function. 
 (_initialize_printcmd): Do not create disassemble command here. 	*
 cli/cli-cmds.c (disassemble_command): New function.  Implements 
 disassemble command. 	(init_cli_cmds): Create disassemble command here
 instead.

	* gdb.asm/asm-source.exp: Adjust patter to new disassembler routine
	which explicitly prints the zero offset as "+0".
