Hi,

thanks for testing the code. The MIPS code generator generates MIPS III 
instruction set by default, but if SLJIT_MIPS_32_64 is defined to 1, it also 
uses some MIPS 32 instructions, such as SEB or CLZ. I couldn't find a way to 
automatically detect MIPS 32 so far, but I would be grateful if somebody could 
tell me how to do it.

Regards,
Zoltan
