In postreload.i.04.cse we have
(insn 1364 1363 1366 151 (set (reg:SI 174 [ T.882 ])
(neg:SI (reg/f:SI 732))) 75 {negsi2} (nil)
(expr_list:REG_EQUAL (const:SI (minus:SI (const_int -360
[0xfffffffffffffe98])
(symbol_ref:SI ("recog_data") [flags 0xc0] <var_decl
0xc24c1c recog_data>)))
(nil)))
This is a rather odd construct, as the negative of an address, isn't
really useful for much. Makes one wonder if maybe something has already
gone wrong earlier.
This odd construct confuses rs6000_machopic_legitimize_pic_address which
only handles (const (plus ...)).
