hi, David,
thank you for your reply, I checked my .s file and find there
indeed many ".set mips32r2" directive, but In the command I transfer
the .cpp file to .s file, I added the option "-march=loongson2f -
mtune=loongson2f", I don't know why the ".set mips32r2" directive were
added in the .s file. do you know how to remove that kind of directive
when I transfer the .cpp to .s file.
Thandk you very much!
