    TableGen supports the 'foreach' block, which textually replicates +the loop body, substituting iterator values for iterator references in the +body. Example:

    + +
    +
    +foreach i = [0, 1, 2, 3] in {
+  def R#i : Register<...>;
+  def F#i : Register<...>;
+}
+
    +
    + +

    This will create objects R0, R1, R2 and +R3. foreach blocks may be nested. If there is only +one item in the body the braces may be elided:
