+Subject: [PATCH 61/61] Author: Nagaraju <nmekala@xilinx.com> Date: Wed Apr
+ 17 14:11:00 2019 +0530
+
+ [Patch, microblaze]: MB-64 removal of barrel-shift instructions from default
+ By default MB-64 is generatting barrel-shift instructions. It has been
+ removed from default. Barrel-shift instructions will be generated only if
+ barrel-shifter is enabled. Similarly to double instructions as well.
