Thank you for your reply!

I tried to use this in the following code:

 tree func_decl =3D gimple_call_fndecl(stmt); // stmt is the function call
statement
function* f =3D DECL_STRUCT_FUNCTION(func_decl);
std::cerr << get_name(f->decl) << std::endl;

However, it seems the last line throws an exception as follows:

during GIMPLE pass: XXX  // here XXX is my pass name
internal compiler error: Segmentation fault
...

That seems strange. Does that seem familiar to you by any chance? Thank
you!

Best,
Shuai
