I don't understand where you are trying to emit the call instruction.
Why do you only have the name?  What language are you compiling?

Certainly calling lookup_name seems wrong.

Given a CALL_EXPR, you can use get_callee_fndecl to find the caller.

At the RTL level, you can usually use TARGET_ENCODE_SECTION_INFO and
SYMBOL_REF_FLAG to good effect.  Or look at how ARM handles
ENCODED_LONG_CALL_ATTR_P via TARGET_STRIP_NAME_ENCODING.
