>is it possible to (cross-)compile plan9 sources on Linux ? i did that for Solaris years ago. the compilers are the easy bit; you also need to modify mkfiles to add a root variable. (it was 8 years ago and i can't remember many details.) for Linux, now, you're probably better off if you can get THNX going, which makes plan 9 run as a guest under Linux. better still is just to build or borrow a cheap machine and run Plan 9 on it.
i'll need to look at the chart, if i can find one, that gives the differences between the various arm stages. until the most recent revisions with FP i didn't think there was much of interest to add to the compiler, from C's point of view. (the compiler does generate the old FP.)
