Subject: [Qemu-devel] [PATCH 04/12] lsi53c895a: avoid a write only variable
Date: Fri, 8 Oct 2010 21:23:52 +0000 [thread overview]
Message-ID: <AANLkTi=yZ-v2qX0g_Cr7U_4C6eph8ARjQUFDeER2jTWN@mail.gmail.com> (raw)
Compiling with GCC 4.6.0 20100925 produced a warning:
/src/qemu/hw/lsi53c895a.c: In function 'lsi_do_msgout':
/src/qemu/hw/lsi53c895a.c:848:9: error: variable 'len' set but not
used [-Werror=unused-but-set-variable]
Fix by adding a dummy cast so that the variable is not unused for
non-debug case.
