Subject: [U-Boot] [PATCH 2/6] config.mk: Make cc-option create a file under include/generated
Date: Wed, 8 Feb 2012 15:58:16 -0700 [thread overview]
Message-ID: <1328741900-18174-2-git-send-email-trini@ti.com> (raw)
In-Reply-To: <1328741900-18174-1-git-send-email-trini@ti.com>
Testing for -fstack-usage requires the creation of an output file, which
isnt possible with /dev/null.
