Thanks. I am working for it now.
But I have a question about how to debug the cc1 with libgcc1.c.
because if I run the cc1 to build the libgcc2.c, lots of errors
occurred.
Run the cc1 with the command:
./cc1 -g -I../../rice-gcc-4.3.0/gcc
-I../../rice-gcc-4.3.0/gcc/../include
../../rice-gcc-4.3.0/gcc/libgcc2.c
here is the error message:
../../rice-gcc-4.3.0/gcc/libgcc2.c:32:21: error: tconfig.h: No such

Did I do something wrong?
Please give me some advice.
Thank you very much.
