error for _muldi3.o

[Shinpei Kato]

Hello,

I got following error messages during porting GCC to a new arch.

../../gcc-3.3.3/gcc/libgcc2.c:366: internal compiler error: in assemble_integer, at varasm.c:1984
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL: http://gcc.gnu.org/bugs.html > for instructions.
make[2]: *** [libgcc/./_muldi3.o] Error 1
make[2]: Leaving diretory `$BUILD_DIR/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/BUILD_DIR/gcc'

I think this is my fault not gcc because MIPS doesn't have this error.
Anyway what muldi3 means? I think it's related to the muldi3 insn since at 366 of libgcc2.c seems for muldi3 insn. 
However, if I remove the insns of mult for DImode (means there are only mult insns for SImode), the same error occurs.
This error is caused by $ARCH.md, isn't it? Or other files?
Could you see or guess what's wrong? I hope your advice.

Regards,
