[LLVMdev] set line number debug info

[Abhirup Ghosh]

Hi,
      I am new to LLVM infrastructure. Recently I am trying to set the debug
info for an instruction. The main aim is to set the source line number of an
instruction. Can anyone please show how to do that?
      I think  that setMetadata method in Instruction class is to be used.
But how do I create MDNode* consisting of desired source line number. Source
line number can be extracted from the instruction-debug-info using
getMetadata method and then using getLineNumber method from DILocation
class. Unfortunately DILocation class does not have any function like
setLinenumber.
