They do different things. the ?i series is mainly intended to debug and
improve the compilers:
it emulates only so much of the architecture and system, enough to get the
compiler and libc going.
5e's a nice bit of work (except for the limitation to little-endian host).
the emulation of /proc was i

my memory
Anybody with an ARM Plan 9 willing to run a binary for me? It just emits a
few lines out of output and I promise it is not a virus.

Your libc is obviously not up-do-date.

It's defined in the libc. You can add it
to /sys/include/libc.h if you wish.

Ok, linking gives:
main: undefined: ainc in main
Looks to be a function (which also seems to be undeclared in 5e.c), anybody
know where it is located?

Thanks. What's the most sane way of downloading
aiju wrote an arm emulator for 9front some time ago and
i remember he implemented floating point on it.
might have a look there:

yes. the instructions are not implemented. unfortunately abort()
was called without flushing the output, so the error message wasn't
printed.

with 5c/5l and then 5i it, it gives:
undefined instruction trap pc #102c inst ed9b0100 class 92
Is floating point supported with 5i?
