Hello, I am sorry to rush mails. But I found the patch I sent was already included in GCC4.4.0 libgcc2.h. So please ignore my previous mail.
Returning to original problem,apparently L_bswapdi2 is somewhere defined. But I could not find L_bswapdi2 defined anywhere. Where and how is it defined ? #ifdef L_bswapdi2 DItype __bswapdi2 (DItype u) Masahiro Ariga
