From af01da22797795408d45dcf03076dc8153c7029e Mon Sep 17 00:00:00 2001
From: Mahesh Bodapati <mbodapat@xilinx.com>

Subject: [PATCH 21/54] [Patch, microblaze]: Correct the const high double
immediate value with this patch the loading of the DI mode immediate values
will be using REAL_VALUE_FROM_CONST_DOUBLE and REAL_VALUE_TO_TARGET_DOUBLE
functions, as CONST_DOUBLE_HIGH was returning the sign extension value even
of the unsigned long long constants also
