[LLVMdev] How to add extern function declaratioin to llvm bc?

[Heming Cui]

Dear all,
    I am wondering if there is some API to add extern function declaration
to bc file. For example, as given below, I want to add the line "extern void
foo();" to my bc file with some llvm methods, how can I do this, please?


extern void foo();              // the llvm bc code is: declare void
@_Z3foov().          How can I add this line to llvm bc using some llvm
methods?

int main() {
  foo();
}
