[LLVMdev] Operand, instruction

[help__me_please]

Can you tell how to use vector globally? I mean, i am able to add entries to 
a vector in a basicblock, but whenever a basicblock function call is
returned, the vector becomes empty. So how to use data structures globally?
And one thing, where is main ( or same kind of) function in llvm?
Thanks for you reply.
