IMO is a bit suspicious that FP<->int conversions in mips.md operate on both FP
operands, i.e:
(define_insn "fix_truncdfsi2_insn"
[(set (match_operand:SI 0 "register_operand" "=f")
(fix:SI (match_operand:DF 1 "register_operand" "f")))]
...and similar patterns... , as well as:
(define_insn "floatsidf2"
[(set (match_operand:DF 0 "register_operand" "=f")
(float:DF (match_operand:SI 1 "register_operand" "f")))]
...and similar patterns.
One would expect a constraint that describes integer regs for output operand in
the former case and integer regs for input operand in the later case.
