Further tests show that you're right about the non working kernel.
Should the iwmmxt arch be disabled by default on GCC 4.5? At least it would
make it clear that this arch is untested/not supported.

I tried applying this patch:

- [(set (match_operand:SI 0 "nonimmediate_operand" "=rk,r,r,rk,
m,z,r,?z,Uy,z")
+ [(set (match_operand:SI 0 "non

I tried removing the whole movsi section from the machine definition file
(iwmmxt.md) but if I do that GCC refuses to compile. Reading the GCC internals

Is it feasible to disable the affected instruction in the meantime, so that gcc
stops crashing? Or, if this comes from Thumb-2 support, maybe it's possible to
disable Thumb-2 support?
I'm basically loo

I would like to confirm that this bug affects gcc 4.4.2.
Compiling ffmpeg 0.5 triggers it in many places.
It may be a good idea to try to fix this in 4.5 if it's not fixed yet, before
Nov 30th which is the e
