Get the parameter attributes of the call.

Return the function being called if this is a direct call, otherwise return null (if it's an indirect call).

Set the parameter attributes of the call.

This static method is like a constructor. It will create an appropriate call site for a Call, Invoke or CallBr instruction, but it can also create a n

Get the calling convention of the call.

Set the calling convention of the call.

Tests whether a pass name starts with a valid prefix for a default pipeline alias.

Return the intrinsic ID of the intrinsic called by this CallSite, or Intrinsic::not_intrinsic if the called function is not an intrinsic, or if this C

Determine whether the passed iterator points to the callee operand's Use.

Tests if this call site is marked as a tail call.

Whether or not we should populate a PassInstrumentationCallbacks's class to pass name map. This is for optimization purposes so we don't populate it
