-Subject: [PATCH] UPDATE: Fix handling complex PIC moves.
-
-fwprop is putting in the REG_EQUIV notes which are involving the
-constant pic unspecs.  Then, loop may use those notes for
-optimizations rezulting in complex patterns that are not supported by
-the current implementation. The following piece of code tries to
-convert the complex instruction in simpler ones.
-
-The fix is done in development tree: [arc-4.8-dev b55922d] 
-and will be a part of the next release of ARC GNU tools.
-Once that new release happens this patch must be removed.

-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.
