After expand, the newly created 16bit big endian load becomes:

(insn 688 687 689 (set (reg:HI 482)
        (mem:HI (reg/v/f:SI 189 [ ptr ]) [0 MEM[base: ptr_110, offset: 0B]+0 S2
A8])) /vol/gcc/src/hg/trunk/local/gcc/java/jcf-parse.c:1622 -1
     (nil))

(insn 689 688 690 (set (reg:SI 483)
        (ashift:SI (subreg:SI (reg:HI 482) 0)
            (const_int 16 [0x10])))
/vol/gcc/src/hg/trunk/local/gcc/java/jcf-parse.c:1622 -1
     (nil))

(insn 690 689 0 (set (reg/v:SI 185 [ min_line ])
        (lshiftrt:SI (reg:SI 483)
            (const_int 16 [0x10])))
/vol/gcc/src/hg/trunk/local/gcc/java/jcf-parse.c:1622 -1
     (expr_list:REG_EQUAL (zero_extend:SI (reg:HI 482))
        (nil)))

I don't understand why those two loads. Also, the HI load is not split into 2
QI ones.
