But I'm not sure that this matters here, since:
(insn 58 57 59 3 (set (subreg:SI (reg:DI 316 [ iftmp.3_114 ]) 0)
(ne:SI (reg/f:DI 469 [ current_scope.1_1->bindings ])
(const_int 0 [0])))
"/althome/mips/v6/src/gcc/gcc/c/c-decl.me.c":915 501 {*sne_zero_disi}
(expr_list:REG_DEAD (reg/f:DI 469 [ current_scope.1_1->bindings ])
(nil)))
can put only 0 or 1 in the SUBREG, can't it?
