Subject: [U-Boot] [PATCH 7/7] GCC4.6: Squash warning in cmd_mem.c
Date: Mon, 26 Sep 2011 02:26:06 +0200 [thread overview]
Message-ID: <1316996766-14248-7-git-send-email-marek.vasut@gmail.com> (raw)
In-Reply-To: <1316996766-14248-1-git-send-email-marek.vasut@gmail.com>
cmd_mem.c: In function ?do_mem_loop?:
cmd_mem.c:474:25: warning: variable ?junk? set but not used
[-Wunused-but-set-variable]
The assigned variable can be removed because the pointers are volatile so
accesses to their addresses are always generated.
