  I'm trying to port jit of JavaScriptCore to mips, but I failed to
implement Branch(Add Sub Mul)32 for mips since
I don't know a simple way to do overflow detection on MIPS like ARM or X86.

is it possible to remove these Overflow detect in jit runtime?  or who
can tell me a simple way to do Overflow detect on MIPS?

Best Regards
