Consider a reduced version of gcc.c-torture/compile/calls.c:
typedef void *(*T)(void);
void
f1 (void)
{
((T) 0)();
}
arm-none-eabi-gcc -O2 triggers an ICE

This failure started happening sometime between

FWIW, the only change to the arm target in this time interval is:

* config/arm/arm.c (arm_legitimize_address): Split absolute addresses
to alow matching ARM pre-indexed addressing mode.
