Hi Alex,
This appears to be a reload bug. Before reload we have:
(call_insn 12 (call:HI (mem:HI (mem:HI (plus:HI (reg:HI R14)
(const_int 2))))
(const_int 0))
After reload this becomes:
(insn 17 (set (reg:HI R14)
(mem:HI (plus:HI (reg:HI R14)
(const_int 2)))))
(call_insn 12 (call:HI (mem:HI (reg:HI R14))
(const_int 0)))
The uploaded patch fixes this but, not being a reload expert, I am not sure
if this is the correct way to solve the problem. It also seems suspicious that
if this is a generic reload problem, then why has it not been reported and
fixed before now ?
