;cruntime.inc - multi-model assembly macros for interfacing to HLLs

; Copyright (c) Microsoft Corporation. All rights reserved.
|
||||
;
|
||||
;Purpose:
|
||||
; This file defines the current memory model being used.
|
||||
;
|
||||
;*******************************************************************************
|
||||
|
||||
;==============================================================================
|
||||
;
|
||||
;Use the following defines to control processor/segment model
|
||||
;
|
||||
; default is -DI86 -Dmem_S
|
||||
;
|
||||
;==============================================================================
|
||||
;
|
||||
;The following variables are defined by this file:
|
||||
; cpu 86, 286, or 386
|
||||
; mmodel english name of the memory model, i.e. "Medium"
|
||||
; ISIZE, LSIZE, NSIZE size of ints, longs, shorts
|
||||
; FLTSIZE, DBLSIZE, LDBLSIZE size of float, double, long double
|
||||
;
|
||||
;The following macros allow easy writing of combined 16/32 bit code:
|
||||
;
|
||||
; 16/32 bit registers:
|
||||
; rax, rbx, rcx, rdx, expand to native registers (rax = eax or ax)
|
||||
; rsi, rdi, rsp, rbp
|
||||
; CBI convert byte to int (al to rax)
|
||||
; Numeric type instructions:
|
||||
; IWORD, LWORD, SWORD data type of int, long, short
|
||||
; DFLOAT, DDOUBLE, DLDOUBLE define float, double, long double
|
||||
;
|
||||
;The following utility macros are provided:
|
||||
; codeseg define/declare code segment
|
||||
; error <msg> stop assembly with message
|
||||
; display <msg> display a message, unless QUIET defined
|
||||
; _if cond <instruction> assemble instruction only if cond is TRUE
|
||||
; _ife cond <instruction> assemble instruction only if cond is FALSE
|
||||
; _ifd symbol <instruction> assemble instruction only if symbol defined
|
||||
; _ifnd symbol <instruction> assemble instruction only if symbol not defined
|
||||
;
|
||||
; lab LabelName assembles to "LabelName:" If DEBUG is defined
|
||||
; LabelName is made public
|
||||
;
|
||||
; JS* (ex. JSE,JSZ,JSB ...) assemble to "je short","jz short","jb short"
|
||||
;
|
||||
; Cmacro look alikes
|
||||
; static* Name, InitialValue, Repeat defines a static variable of type *
|
||||
; global* Name, InitialValue, Repeat defines a global variable of type *
|
||||
; label* Name, {PUBLIC,PASCAL,C} defines a label of type *
|
||||
