[Mono-list] Moonlight and FPU support

Hi all
 
I have been battling for the past few days to get everything in place to
get moonlight running on our embedded arm platform (processor is an
ARM926EJ-Sid(wb) ).  I finally get all the dependencies in place, but
when it comes to running the glassyclock example, I get a 'should not be
reached' error from within inssel.c.  This turns out to be a catchall
exception thrown when compiling mono with no hardware FPU support (the
SOFT_FLOAT_IMPL) flag.
 
Is my understanding from this that moonlight will not run on hardware
without hardware floating point support, or is it a case of implementing
the missing functionality to get this working.  There does seem to be
other instructions implemented in inssel-float.brg that target a
platform with software based FPU (for example CEE_STIND_R8, whereas
CSS_STIND_R4 does not).
 
Regards
 
Matt
