+// History
+//==============================================================
+// 02/20/00 Initial version
+// 08/17/00 Changed predicate register macro-usage to direct predicate
+//          names due to an assembler bug.
+// 02/06/02 Corrected .section statement
+// 05/20/02 Cleaned up namespace and sf0 syntax
+// 02/06/03 Reordered header: .section, .global, .proc, .align;
+//          added missing bundling
+
+//
+// Assembly macros
