Those folks running OS-9/6809 and hacking C, I have a recommendation:
grab Carl Kreider's hacks of clib.l.  Mr. Kreider has rewritten a fair
number of library routines in assembumbler, to respectable advantage in
speed and size.

To give you an example--you'll recall my previous posting about running
dhry.c on a 2MHz 6809, in which I said that with register variables and
with global scalars forced to the direct page it ran something like
247 Dhrystones/second?  Well, I recompiled and ran with the revised clib.l,
and under the same conditions (register and direct page) I got 278
Dhrystones/second.  (Turning off stack overflow checking got it up to
303 Dhrystones/second.)

I think the major reason for the speedup on the Dhrystone benchmark is
that Microware C doesn't do structure assignment inline--you have to call
a function, and Mr. Kreider did hack _strass().  If the compiler supported
structure assignment, the 6809 would make an even better showing.  (eh, eh,
nudge, nudge?)
