Subject: Dynamic binary optimization?
Date: Tue, 5 Jan 2010 10:31:03 -0700	[thread overview]

I've been having problems with my intrusion detection software recently (aide). It's pointing to
modified binaries and libraries on several boxes. At first I was treating this as a malicious
invasion but as I've gone through the steps for that I'm more and more sure that the systems are not
actually compromised. After some thought, we remembered a discussion about something that tries to
dynamically optimize executables for the particular hardware they are running on.

Web searches have yielded plenty of information about dynamic optimization or dynamic adaptation but
nothing specific to Linux or to a particular product. Does anybody have any information about that?

TIA
