From 8fe4bb98e42945ddf2c0d47cec647ef76909e812 Mon Sep 17 00:00:00 2001 From: "Steven J. Hill" Date: Mon, 25 Mar 2013 12:07:40 -0500 Subject: [PATCH] MIPS: microMIPS: Fix incorrect mask for jump immediate. Jump or branch target addresses have the first bit set. The original mask did not take this into account and will cause a field overflow warning for the target address when a jump immediate instruction is built. Signed-off-by: Steven J.
