[Qemu-devel] [PATCH v2 3/5] disas: nanoMIPS: Fix a function misnomer


From: Aleksandar Markovic
Subject: [Qemu-devel] [PATCH v2 3/5] disas: nanoMIPS: Fix a function misnomer
Date: Mon, 17 Dec 2018 18:10:05 +0100

From: Aleksandar Markovic <address@hidden>

Fix wrong name of a function. The convention in this file is that
names of extraction functions should reflect bit patterns they are
extracting.
