| * This will break whenever the contents of StructType are rearranged. |

| * |
| * Declares that the expected size of Type is "size". |
| * |
| * MTERP_CONSTANT(name, value) |
| * |
| * Declares that the expected value of "name" is "value". Useful for |
| * enumerations and defined constants that are inaccessible to the |
| * assembly source. (Note this assumes you will use the same name in |
| * both C and assembly, which is good practice.) |
| * |
| * In all cases the "name" field is the label you will use in the assembler. |
| * |
| * The "value" field must always be an actual number, not a symbol, unless |
| * you are sure that the symbol's value will be visible to both C and |
| * assembly sources. There may be restrictions on the possible range of |
| * values (which are usually provided as immediate operands), so it's best |
| * to restrict numbers assuming a signed 8-bit field. |
| * |
| * On the assembly side, these just become "name=value" constants. On the |
| * C side, these turn into assertions that cause the VM to abort if the |
| * values are incorrect. |
