Subject: [PATCH] PR gdb/16305: Mask out PREFIX_ADDR when adding prefix to opcode
Date: Sun, 08 Dec 2013 20:14:00 -0000	[thread overview]
Message-ID: <20131208201430.GA14252@intel.com> (raw)

PREFIX_ADDR isn't a prefix to opcode.  This patch masks out PREFIX_ADDR
when adding prefix to opcode. Tested on Linux/x86-64.  OK to install?

Thanks.

H.J.
