-Subject: [PATCH] Don't allow mcompact-casesi for ARCv2
-
-The compact casesi is not working for arcv2 processors family as it
-makes use of the add_s rx,rx,pcl instruction which is only valid for
-arc6xx and arc700 processors. Also not having this instruction makes
-no much sens to change the compact-casesi pattern to use normal add
-instructions as it nullifies the advantage of short instruction use.
-The default casesi pattern betters suits the arcv2 architecture.
-
-The fix is done in development tree: [arc-4.8-dev 0946382] 
-and will be a part of the next release of ARC GNU tools.
-Once that new release happens this patch must be removed.

-	* common/config/arc/arc-common.c (arc_option_optimization_table):
-	Remove mcompact-casesi option.
-	* config/arc/arc.c (arc_override_options): Use compact-casesi only
-	for arcv1.
-	* config/arc/arc.md (casesi_load): Use short instructions.
