internal compiler error: in reload_combine_note_use, at postreload.c:1093

[daniel tian]

I have ported gcc4.0.2  to 32bit RISC chip. But internal compiler
error happened: in reload_combine_note_use, at postreload.c:1093 . I
tracked the code with insight.  error occurred in "CASE REG", when the
register number is larger than FIRST_PSEUDO_REGISTER. Does this mean
the reload register allocation failed?  What I know is that there is
no pseudo register used after reload completed (Is this right?).

Can anyone give me some advice?

Any suggestion is appreciated.
Thank you very much.
