--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
I am not sure if this is related or not, but for a raspberry pi cross compiler
(arm-linux-gnueabihf) and gcc/testsuite file gcc.dg/vect/pr57558-2.c,
it seems to compile ok at -O2, but not at -O3:
./gcc.dg/vect/pr57558-2.c
during RTL pass: expand
./gcc.dg/vect/pr57558-2.c: In function ‘foo’:
./gcc.dg/vect/pr57558-2.c:9:13: internal compiler error: in gen_movdi, at
config/arm/arm.md:5257
