;
|
|
;Purpose:
|
|
; This file defines the current memory model being used.
|
|
;
|
|
;*******************************************************************************
|
|
|
|
;==============================================================================
|
|
;
|
|
;Use the following defines to control processor/segment model
|
|
;
|
|
; -DI86 8086/8088 processor
|
|
; -DI286 80286 processor
|
|
; -DI386 80386 processor with 32-bit code/data segment
|
|
;
|
|
; -Dmem_S Small memory model (near code, near data)
|
|
; -Dmem_M Medium memory model (far code, near data)
|
|
; -Dmem_C Compact memory model (near code, fat data)
|
|
; -Dmem_L Large memory model (far code, far data)
|
|
;
|
|
; -DSS_NEQ_DGROUP SS and DS point to different segments
|
|
;
|
|
; default is -DI86 -Dmem_S
|
|
;
|
|
;==============================================================================
|
|
;
|
|
;The following variables are defined by this file:
|
|
; cpu 86, 286, or 386
|
|
; sizeC code distance; 1 = far code, 0 = near code
|
|
; sizeD data distance; 1 = far data, 0 = near data
|
|
; 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
|
|
; NPSIZE, FPSIZE size of near/far pointers
|
|
; CPSIZE, DPSIZE size of code/data pointers
|
|
; ISHIFT, LSHIFT bits to shift to convert byte to int/long
|
|
;
|
|
;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
|
|
; 16/32 bit register instructions:
|
|
; JRCXZ jump when rcx is zero
|
|
; CBI convert byte to int (al to rax)
|
|
; CAXDX convert rax to rax:rdx
|
|
; ZXAL, ZXBL, ZXCL, ZXDL zero extend al,bl,cl,dl to rax,rbx,rcx,rdx
|
|
; Pointer instructions:
|
|
; LPDS, LPES load data pointer with ES or DS
|
|
; PDS, PES segment overrides when pointer loaded as above
|
|
; PCS, PSS segment override to get at code/stack segment
|
|
; LFPDS, LFPES load far pointer with ES or DS
|
|
; FPDS, FPES segment overrides when pointer loaded as above
|
|
; CPTR data type of code pointer
|
|
; CPDIST distance of code (near/far)
|
|
; DNPTR, DFPTR define near/far pointer
|
|
; DCPTR, DDPTR define code/data pointer
|
|
; DCPTR?, DDPTR? define uninitialized code/data pointer
|
|
; CPWORD, DPWORD data type of code or data pointer
|
|
; Numeric type instructions:
|
|
; IWORD, LWORD, SWORD data type of int, long, short
|
|
; DINT, DLONG, DSHORT define int, long, short
|
|
; DFLOAT, DDOUBLE, DLDOUBLE define float, double, long double
|
|
; Offsets:
|
|
; codeoffset, dataoffset offsets from code and data segments
|
|
; API calls:
|
|
; APIDIST distance of API calls (near/far)
|
|
; APIEXT ApiName extrn declaration for an API function
|
|
;
|
|
;The following utility macros are provided:
|
|
; codeseg define/declare code segment
|
|
; error <msg> stop assembly with message
|
|

; _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 *
|
|
