From ee1ce9a4b1a52f62a73b5a5fae36fe3d8a0186b0 Mon Sep 17 00:00:00 2001 From: Markos Chandras Date: Fri, 17 Jul 2015 10:36:03 +0100 Subject: [PATCH] MIPS: math-emu: Allow m{f,t}hc emulation on MIPS R6 commit e8f80cc1a6d80587136b015e989a12827e1fcfe5 upstream. The mfhc/mthc instructions are supported on MIPS R6 so emulate them if needed.
