re PR target/47551 (ICE when reloading neon registers from out-of-range offsets)
gcc/
PR target/47551
* config/arm/arm.c (coproc_secondary_reload_class): Handle
structure modes. Don't check neon_vector_mem_operand for
vector or structure modes.
gcc/testsuite/
PR target/47551
* gcc.target/arm/neon-modes-2.c: New test.
