[LLVMdev] opt problem

[Jianing Zhao]

Hi,

When I use the opt --insert-block-profiling command, there is " opt: Unknown command line argument '-insert-block-profiling'." 

When I use the opt -insert-edge-profiling t1.bc -o t1profile.bc, there is an error "Invalid MODULE_CODE_FUNCTION record" .

Does anyone know how to solve the problem? Thanks very much!

Best,

Jianing
