--- Comment #3 from Martin Husemann <martin at netbsd dot org> ---
Matt asked for the instruction involved - I think it is this:
(insn 245 244 246 51 (set (mem:HI (reg/v/f:SI 1 %r1 [orig:67 sup ] [67]) [2
*sup_104+0 S2 A16])
(plus:HI (subreg:HI (mem/u/c:SI (plus:SI (mult:SI (reg/v:SI 0 %r0
[orig:81 count ] [81])
(const_int 4 [0x4]))
(symbol_ref:SI ("DECPOWERS") [flags 0x40] <var_decl
0x7f22fe60 DECPOWERS>)) [3 DECPOWERS S4 A32]) 0)
(const_int -1 [0xffffffff])))
