In
(insn 37 86 40 4 t.f:9 (parallel [
(set (reg:SI 2 cx [74])
(const_int 0 [0x0]))
(set (reg/f:SI 5 di [72])
(plus:SI (ashift:SI (reg:SI 2 cx [74])
(const_int 2 [0x2]))
(reg/f:SI 5 di [72])))
(set (mem/s/j:BLK (reg/f:SI 5 di [72]) [0 line+80 A32])
(const_int 0 [0x0]))
(use (reg:SI 0 ax [73]))
(use (reg:SI 2 cx [74]))
]) 856 {*rep_stossi} (expr_list:REG_DEAD (reg:SI 0 ax [73])
(expr_list:REG_UNUSED (reg/f:SI 5 di [72])
(expr_list:REG_UNUSED (reg:SI 2 cx [74])
(nil)))))
the MEM_EXPR of
(set (mem/s/j:BLK (reg/f:SI 5 di [72]) [0 line+80 A32])
(const_int 0 [0x0]))
is bogus, it should be line, not line+80. Does forwprop adjust MEM_EXPRs
properly?
