pre-processed source
When compiling the attached pre-processed source for arm (-march=armv7-a
-mtune=cortex-a8) and using options -mfpu=neon -g -O1 I get an ICE.
kaltsi@kaltsnatty:~/tmp/ice$ arm-linux-gnueabi-gcc-4.5 -mfpu=neon -O1 -g -c
emit-rtl-ice.i
optimized.c: In function ‘move_16bit_to_32bit’:

Please submit a full bug report,

This does not happen if I leave the -g option out.
