[ Posted to linux-7110 and linux-arm ]
At the moment, I'm playing around with a few programs from
ftp://ftp.arm.linux.org.uk/pub/armlinux/RedHat/RPMS/ on my Psion
(CL-PS7110 CPU, with an ARM710a core) and I got "Illegal instruction" a
few times, e.g. from dip and from rz. Unfortunately, the kernel (2.1.125)
is silent about what instruction that may have been.
Any ideas of what this may be ? My suspicion is either the 16 bit
transfer instructions that other ARM CPUs seem to have, or some
floating-point operations. Or maybe it's just the rather limited
environment in which I'm running things that causes programs to try
stupid things ...
If it's the 16 bit transfers, we'll probably have to emulate them if they
appear in common ARM code :-( (I know that there's an FPU emulator in
more recent kernels.)
