// Purpose:     A quick test of whether we can decode opcodes properly.  This
8
//              test bypasses the assembler, and is useful when the assembler
9 70 dgisselq
//      isn't working.  Now that we've got the assembler running, this code
10
//      isn't nearly as useful anymore.

//
12 70 dgisselq
//      Even more, now that we switched instruction sets, this code is all the
13
//      more useless ... until updated.
