Hi, Jeff:
Thanks. I fixed the bug. The problem is in GO_IF_LEGITIMATE_ADDRESS. In
the reload processing, find_reload function will check the operand address
whether it is effective. I traced the function, and found my
GO_IF_LEGITIMATE_ADDRESS macro thought the following address is strict
legitimate address:
mem/s:SI (plus:SI (reg/v/f:SI 91 [ frame ])
(const_int 4 [0x4]))
Of course it is not a valid address in strict mode. And a logical error was
found in my rice_reg_ok_for_base function. After fixing it, cc1 works well .
Thank you very much!
Daniel.tian
