9084
+; There are two types of calls: "call" and "call_value".
9085
+;
9086
+; Each of these types of calls are then expanded into one of:
9087
+;
9088
+;      _const          - A call to a constant address, such as a symbol
9089
+;                      reference or a fixed location
9090
+;
9091
+;      _label          - This should be the same as _const, except that for
9092
+;                      some reason the RTL and matching rules are separate.
9093
+;                      Hence we have a separate rule for this.
9094
+;
9095
+;      _mem            - The memory address we wish to jump to is stored in
9096
+;                      memory somewhere, and we have only a pointer.  In this
9097
+;                      case, we load that pointer straight to the PC and go.
9098
+;
9099
+;      _var            - The address to jump to is given as an offset to a
9100
+;                      register, such as X+R3.  This is an indirect jump.
9101
+;                      Although we support it, it does require different RTL
9102
+;                      code.
