For instance, it does not comprehend the REX prefix which is used on all 64-bit instructions. They instead get decoded as "inc" and "dec". This makes the disassembly useless, and the debugger hard to use. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: From: Nate Eldredge To: FreeBSD-gnats-submit@FreeBSD.org Cc: Nate Eldredge Subject: Re: amd64/86487: DDB disassembler broken on amd64 Date: Thu, 22 Sep 2005 23:54:02 -0700 (PDT) Never mind. It appears the CURRENT code is much improved. I am a fool and should have looked at it first.
