| 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. | |
