--- Comment #3 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
cond_exec_process_insns is throwing a wobbly, since it is not expecting to
handle a jump insn (in this case a return).
(jump_insn 62 61 51 4 (parallel [
(return)
(set/f (reg/f:SI 13 sp)
(plus:SI (reg/f:SI 13 sp)
(const_int 16 [0x10])))
(set/f (reg:SI 3 r3)
(mem/c:SI (reg/f:SI 13 sp) [25 S4 A32]))
(set/f (reg:SI 4 r4)
(mem/c:SI (plus:SI (reg/f:SI 13 sp)
(const_int 4 [0x4])) [25 S4 A32]))
(set/f (reg:SI 5 r5)
(mem/c:SI (plus:SI (reg/f:SI 13 sp)
(const_int 8 [0x8])) [25 S4 A32]))
(set/f (reg:SI 15 pc)
(mem/c:SI (plus:SI (reg/f:SI 13 sp)
(const_int 12 [0xc])) [25 S4 A32]))
]) image.c:1709 -1
(expr_list:REG_UNUSED (reg:SI 15 pc)
(expr_list:REG_UNUSED (reg:SI 3 r3)
(expr_list:REG_CFA_RESTORE (reg:SI 5 r5)
(expr_list:REG_CFA_RESTORE (reg:SI 4 r4)
(expr_list:REG_CFA_RESTORE (reg:SI 3 r3)
(nil))))))
-> return)
Seems to work with 4.7, so a regression.
