gcc definitely has that option. One just has to rewrite some
parts of the ARM32 files. gcc also has options for variable
length instructions, and other nice stuff. I checked this
1-2 years ago when I wanted to write an inline math library
for RiscBSD. It was dropped because gcc could not be compiled
by ordinary users then.

I read a little in my ARM documentation in the weekend.
If it really is so that it is the LDM^ instruction that is
affected, then why not just replace it with LDM, and do the ^ part
with a separate instruction?

We need a better description of the bug, or some code that shows
the behaviour without crashing the machine.
