|

| 8 | ; This file provides macro definitions for NASM files.

| 12 | ; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
|
|---|
| 13 | ; For example, to define a structure called mytype containing a longword,
|
|---|
| 14 | ; a word, a byte and a string of bytes, you might code
|
|---|
| 15 | ;
|
|---|
| 16 | ; struc mytype
|
|---|
| 17 | ;
|
|---|
| 18 | ; mt_long: resd 1
|
|---|
| 19 | ; mt_word: resw 1
|
|---|
| 20 | ; mt_byte: resb 1
|
|---|
| 21 | ; mt_str: resb 32
|
|---|
| 22 | ;
|
|---|
| 23 | ; endstruc
|
|---|
| 24 | ;
|
|---|
| 25 | ; Below macros are help to map the C types and the RESB family of pseudo-instructions.
|
|---|
| 26 | ; So that the above structure definition can be coded as
|
|---|
| 27 | ;
|
|---|
| 28 | ; struc mytype
|
|---|
| 29 | ;
|
|---|
| 30 | ; mt_long: CTYPE_UINT32 1
|
|---|
| 31 | ; mt_word: CTYPE_UINT16 1
|
|---|
| 32 | ; mt_byte: CTYPE_UINT8 1
|
|---|
| 33 | ; mt_str: CTYPE_CHAR8 32
|
|---|
| 34 | ;
|
|---|
| 35 | ; endstruc
|
|---|
| 36 | %define CTYPE_UINT64 resq
|
|---|
| 37 | %define CTYPE_INT64 resq
|
|---|
| 38 | %define CTYPE_UINT32 resd
|
|---|
| 39 | %define CTYPE_INT32 resd
|
|---|
| 40 | %define CTYPE_UINT16 resw
|
|---|
| 41 | %define CTYPE_INT16 resw
|
|---|
| 42 | %define CTYPE_BOOLEAN resb
|
|---|
| 43 | %define CTYPE_UINT8 resb
|
|---|
| 44 | %define CTYPE_CHAR8 resb
|
|---|
| 45 | %define CTYPE_INT8 resb
|
|---|
| 46 |
|
|---|
| 47 | %define CTYPE_UINTN resd
|
|---|
| 48 | %define CTYPE_INTN resd
