[Vm-dev] ARM Simulator whitewash...

Hi All,
anyone with C chops looking for a challenge? The ARM code generator in
Cog is in a good state and we're supporting Squeak 5.0 Cog on ARM and
building Newspeak Cog VMs for ARM. But the same can't be said of the
simulator, with which we develop the code generator. Tim Rowledge recently
added support for floating point support for the ARM code generator, which
is great for floating point performance, but alas the simulator can't
simulate the generated vfp (virtual floating point) instructions. The
simulator is derived from Gdb's ARM support, see
http://www.squeakvm.org/svn/squeak/branches/Cog/processors/ARM/README
http://www.squeakvm.org/svn/squeak/branches/Cog/processors/ARM/gdb-7.6
Is anyone interested in fixing the ARM simulator so that it does correctly
simulate vfp instructions? If so, let me know and I can help you set up
the relevant environment.
_,,,^..^,,,_
best, Eliot
