Hi Andrew
                I am newbie. There are many headers and classes, I do not know how to use to add dwarf info to bc file.
                Can  you show me the demo or example, is there any info about how to use these classes step by step.

Have a look at the DebugInfo API.

include/llvm/DebugInfo/*

It requires using the C++ API instead of the C API.

Hi,
                I create the function  A with llvm api, and make implement about function, that function A call function B, and add some write/read operation of variants to function A. and compile it to machine code, run it debug it.
                And I want to debug the function A, is there any ways I can add some dwarf info (or debug info ), so that I can the check variant ‘s value is ok.
