libcalls (that are made in the current module) at the beginning of the assembly
file. The class “Module” does not maintain any list of the libcalls
made during the program. Although, it maintains lists of all the global

Traversing each instruction and its operand to find if any libcall has been
invoked seems to be very very costly. Is there some other way to find the
libcalls that are made in module? <o:p></o:p></span></font></p>
