[LLVMdev] arithmetical operands signedness

[Jonas Paulsson]

Hi,

my target handles operands of multiplying instructions differently based on signedness. 

I wonder then how I would do instruction selection based on the operands signs?

The mul instruction sets a nsw for signed, but when i try unsigned ops, there is no wrap flag at all. I'm not sure this is enough information to work with, or?
