From 01f72885794124f94b24d97daf3c8630424cfd79 Mon Sep 17 00:00:00 2001 From: Leon Alrae Date: Fri, 27 Jun 2014 08:49:04 +0100 Subject: target-mips: Status.UX/SX/KX enable 32-bit address wrapping In R6 the special behaviour for data references is also specified for Kernel and Supervisor mode. Therefore MIPS_HFLAG_UX is replaced by generic MIPS_HFLAG_AWRAP indicating enabled 32-bit address wrapping.
