The currently supported directives are:
| Name | Description |
|---|---|
| .align | Align next data item on specified byte boundary (0=byte, 1=half, 2=word, 3=double) |
| .ascii | Store the string in the Data segment but do not add null terminator |
| .asciz | Store the string in the Data segment and add null terminator |
| .byte | Store the listed value(s) as 8 bit bytes |
| .data | Subsequent items stored in Data segment at next available address |
| .double | Store the listed value(s) as double precision floating point |
| .end_macro | End macro definition. See .macro |
| .eqv | Substitute second operand for first. First operand is symbol, second operand is expression (like #define) |
| .extern | Declare the listed label and byte length to be a global data field |
| .float | Store the listed value(s) as single precision floating point |
| .globl | Declare the listed label(s) as global to enable referencing from other files |
| .half | Store the listed value(s) as 16 bit halfwords on halfword boundary |
| .include | Insert the contents of the specified file. Put filename in quotes. |
| .macro | Begin macro definition. See .end_macro |
| .section | Allows specifying sections without .text or .data directives. Included for gcc comparability |
| .space | Reserve the next specified number of bytes in Data segment |
