From d31846a1b993cfe4b7d983db0e5c140dac3b0220 Mon Sep 17 00:00:00 2001 From: Steve Ellcey Date: Wed, 29 Jan 2014 09:54:34 -0800 Subject: mips: silence 'set but not used' warnings This patch uses 'attribute_unused' to clean up a number of warnings messages that are generated when doing a MIPS build. All of the changes are in MIPS specific files and there are no code changes other then adding the unused attribute where needed.
