[LLVMdev] Need guidance regarding MachineFunctionPass

[John Criswell]

Dear Sachin,

Your description of the problem contains too few details; no one will be 
able to diagnose the problem you're having.  You need to provide more 
information on what, exactly, is not working as you expected.

Regards,

John Criswell
