From c7d4d98ae7057467f48c02a11ad9120021976089 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Mon, 3 Nov 2014 18:51:38 +0000 Subject: target-mips: Make CP1.FIR read-only here too CP1.FIR is read-only in hardware so gdbstub must respect it. We already respect it for CTC1 instructions, so do it here too. Signed-off-by: Maciej W.
