------- Comment #2 from rearnsha at gcc dot gnu dot org  2010-02-06 15:23 -------
Confirmed.  coproc_secondary_reload_class needs to be taught about
reg_equiv_mem (at a minimum).

ARM OABI is no longer a supported target

You tested with an EABI compiler.  The original report stated that the ICE
occurs with arm-linux configurations, i.e. OABI, but not with EABI
configurations.

For gcc 4.5 r171282, arm-none-linux-gnueabi, I can run this command without
error:

arm-none-linux-gnueabi-g++ ~/investigate/pr42949.i -B. -c -O1 -mfpu=vfp

It also works for trunk (r171212).

I therefore think this is fixed or has ceased to be, but it would be good to
get confirmation someone else.
