On hppa64-hp-hpux*, I think we still have the same bug.  Combine is
still generating an insn that reload can't handle:

(insn 16 15 17 0 (asm_operands/v ("") ("") 0 [
            (mem/s/v/j:HI (mem/u/c:DI (lo_sum:DI (plus:DI (reg:DI 27 %r27)
                            (high:DI (symbol_ref:DI ("_const_32") <var_decl 8000
03fffef92340 _const_32>)))
                        (unspec:DI [
                                (symbol_ref:DI ("_const_32") <var_decl 800003fff
ef92340 _const_32>)
                            ] 2)) [0 S8 A64]) [0 _const_32+0 S2 A32])
        ]
         [
            (asm_input:HI ("X"))
        ] ("/test/gnu/gcc-3.3/gcc/gcc/testsuite/gcc.dg/torture/asm-subreg-1.c")
12) -1 (nil)
    (nil))
