I get this same ICE while compiling gcc.c-torture/execute/scal-to-vec2.c at -O1
with a 4.7 configured with  --with-arch=armv7-a --with-fpu=vfp
--with-float=hard .


(gdb) p debug_rtx(insn)
(insn 357 1038 1041 (set (reg:SI 14 lr)
        (zero_extend:SI (mem/u/c:HI (symbol_ref/u:SI ("*.LC0") [flags 0x2]) [0
S2 A16]))) t.c:49 161 {*arm_zero_extendhisi2_v6}
     (nil))
$4 = void

Both arm_zero_extendhisi2 and arm_zero_extendhisi2_v6 are missing
pool_range/neg_pool_range .
