;
; Macro for the PVALIDATE instruction, defined in AMD APM volume 3.
; NASM feature request URL: https://bugzilla.nasm.us/show_bug.cgi?id=3392753
;
%macro PVALIDATE       0
    DB 0xF2, 0x0F, 0x01, 0xFF
%endmacro

;
; Macro for the RMPADJUST instruction, defined in AMD APM volume 3.
; NASM feature request URL: https://bugzilla.nasm.us/show_bug.cgi?id=3392754
;
%macro RMPADJUST       0
    DB 0xF3, 0x0F, 0x01, 0xFE
%endmacro

; NASM provides built-in macros STRUC and ENDSTRUC for structure definition.
; For example, to define a structure called mytype containing a longword,
; a word, a byte and a string of bytes, you might code
;
; struc   mytype
;
;  mt_long:      resd    1
;  mt_word:      resw    1
;  mt_byte:      resb    1
;  mt_str:       resb    32
;
; endstruc
;
; Below macros are help to map the C types and the RESB family of pseudo-instructions.
; So that the above structure definition can be coded as
;
; struc   mytype
;
;  mt_long:      CTYPE_UINT32    1
;  mt_word:      CTYPE_UINT16    1
;  mt_byte:      CTYPE_UINT8     1
;  mt_str:       CTYPE_CHAR8     32
;
; endstruc
