C compiler -xarch and -xtarget

All, does any have a little better description of the -xarch and -xtarget options for the Sun Compiler? What is the default for both if nothing is specified? Thanks in advance,

It's easy to see defaults, just supply '-#' option and look at the output.Also, I'd recommend to read Chris' blog entry: http://blogs.sun.com/quenelle/entry/goodbye_xarch_amd64_hello_m64
