I just found this on the openvms page:

   (http://www.openvms.digital.com/openvms/21264_CONSIDERATIONS.html)

   Ensuring Proper Use of Interlocked Memory Instructions

   The Alpha Architecture Reference Manual, Third Edition (AARM)
   describes strict rules for using interlocked memory
   instructions. The forthcoming Alpha 21264 (EV6) processor and all
   future Alpha processors are more stringent than their predecessors
   in their requirement that these rules be followed. As a result,
   code that has worked in the past despite noncompliance may now fail
   when executed on systems featuring the new 21264 processor.

Does anyone know if this is relevant to gcc on linux? The above page
includes a tool which finds inconsistencies in a binary (on VMS
systems, of course):

   http://www.openvms.digital.com/openvms/srm_check.exe

Does anyone know if such a thing is needed and/or available for Linux?
I didn't find any such caveats on the "Tru64 Unix" pages.
