Re: updated P4 timings

[Camm Maguire <camm@enhanced.com>]

Greetings!  Just an update on the P4 SSE2.  Downloaded the intel specs
today, and it seems as though all the instructions are the same with
the trailing 's' replaced by a 'd', i.e. addps -> addpd, etc.  Anyway,
it seems as though the assembler has not yet caugt up with this:

Guess we have to wait for a new assembler update.

Take care,
