Dear GCC Developers,
I have problems with a dlx backend, which I have ported to GCC 4.1.1.
During compilation of gcc I get warnings about missing mode definitions
in the machine description file. The following instruction template is
affected:
---snip---
;;
;; calls that return int in r1
;;
(define_insn "call_val_internal_return_r1"
[(parallel [(set (reg:SI 1)
(call (match_operand:QI 0 "sym_ref_mem_operand" "")
(match_operand 1 "" "i")))
(clobber (reg:SI 31))])]
""
"jal\\t%S0%("
[(set_attr "type" "jump")
(set_attr "mode" "none")])
---snap---
I think the warning is caused by the second parameter of the set
instruction, right? But I don't know where to specify the source mode. I
had already a look into the GCC Internals Manual without success.
Any suggestions how to fix this problem?
Regards,
Markus Franke
