Re: invalid insn generated
I have already have both and it still does that.
It seems that after we get here, nothing would stop gcc from emiting
such an invalid insn (tem = emit_insn (gen_move_insn (out, in));). So
I think that maybe the problem is that I got there with these in and
out arguments.

the emit_insn which should emit a move insn gets as out a register
from class D and as in the Stack pointer.
In my port there is no insn which can write directly from sp to d. so
the emitted insn is invalid and the compilation terminates.
What might be the problem?
Is it possible to arrive to this point with such arguments and later
to fix it or does the problem begin earlier somewhere.
This tends to mean that you haven't set REGISTER_MOVE_COST correctly.
You need to make sure that moves between register class D and the
stack pointer have a cost greater than 2. If you are unlucky you may
have to introduce a secondary reload.

That's correct. You need to figure out how to make that not happen.
(That was the actually the goal of my suggestion, although I didn't say
it, and I guess it was not helpful in any case.)

invalid insn generated
Hi,
In my port I get to gen_reload to the lines
/* If IN is a simple operand, use gen_move_insn. */
else if (OBJECT_P (in) || GET_CODE (in) == SUBREG)
{
static int xxx;
xxx = OBJECT_P (in);
tem = emit_insn (gen_move_insn (out, in));
/* IN may contain a LABEL_REF, if so add a REG_LABEL_OPERAND note. */
mark_jump_label (in, tem, 0);
}
the emit_insn which should emit a move insn gets as out a register
from class D and as in the Stack pointer.
In my port there is no insn which can write directly from sp to d. so
the emitted insn is invalid and the compilation terminates.
What might be the problem?
Is it possible to arrive to this point with such arguments and later
to fix it or does the problem begin earlier somewhere.
Thanks, Roy.
