Dear all,
I'm continuing this port and have run into something strange, if I add
a constraints.md file with only this:
(define_constraint "I"
"A signed 16-bit constant (for arithmetic instructions)."
(and (match_code "const_int")
(match_test "SMALL_OPERAND (ival)")))
(Like one of the constraints from the mips port).
And add a :
(include "constraints.md")
to my md file, I get these during the compilation:

Any ideas why this happens when I add a constraint to my machine description?
As always, thank you very much for your time,
