[Bug target/23783] New: gcc.c-torture/compile/calls.c triggers an ICE

["kazu at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

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

/home/kazu/calls.c: In function 'f1':

This failure started happening sometime between
2005-08-30 07:00UTC and 2005-09-02 07:00UTC.

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

2005-09-01  Nicolas Pitre <nico@cam.org>

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