From a3142792f79884b867b7bf4c7d5a126a0f913332 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 18 Jan 2018 21:07:21 +0300 Subject: [PATCH] ARCv2: Don't pretend we may set L-bit in STATUS32 with kflag instruction As per PRM "kflag" instruction doesn't change state of L-flag ("Zero-Overhead loop disabled") in STATUS32 register so let's not act as if we can affect this bit.
