From: David Holsgrove <david.holsgrove@xilinx.com>
Date: Fri, 28 Sep 2012 16:32:03 +1000
Subject: [PATCH 06/11] [Patch, microblaze]: Add SIZE_TYPE and PTRDIFF_TYPE to
microblaze.h
Fixes warnings like;
warning: format '%zX' expects argument of type 'size_t',
but argument 3 has type 'unsigned int' [-Wformat]
Changelog
2013-03-18 David Holsgrove <david.holsgrove@xilinx.com>
* gcc/config/microblaze/microblaze.h: Define SIZE_TYPE
and PTRDIFF_TYPE.
