From fabd23a354496701b4a9ebf6931485b0d61c7bbe Mon Sep 17 00:00:00 2001
From: Mahesh Bodapati <mbodapat@xilinx.com>
Date: Sat, 26 Aug 2017 19:21:45 -0700
Subject: [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
ChangeLog:
2016-02-03 Nagaraju Mekala <nagaraju.mekala@xilinx.com>
Ajit Agarwal <ajitkum@xilinx.com>
* microblaze.c (print_operand): Use REAL_VALUE_FROM_CONST_DOUBLE &
REAL_VALUE_TO_TARGET_DOUBLE
* long.c (new): Added new testcase
