;; Added defgrp and changed cMerge to Microsoft C
|
|
;; Added copyright message and changed to 1.01
|

|
|
;; 3.xx.a 02/26/87 Walt Moore
|
|
;; Massive rework. Documentation coming.
|
|
;;
|
|
;; 3.xx.b 04/08/87 NeilK
|
|
;; Added parmH, which is like parmW except
|
|
;; that it reserves 4 bytes on frame.
|
|
;;
|
|
;; 3.xx.c 05/11/87 Walt Moore
|
|
;; Added <> to ?ap so that arg <DataOFFSET foo>

|
|
;;
|
|
;; 3.01 07/03/87 Walt Moore
|
|
;; parm_bytes_&procname is now generated for
|
|
;; all cProcs, and is the number of bytes of
|
|
;; parameters to the cProc.
|
|
;;
|
|
;; NO_BP added as a keyword to cProc which
|
|
;; causes all equates to be generated without
|
|
;; reference to BP for the procedure. All type
|
|
;; info is still generated, but the user must
|
|
;; supply any segment and base register.
|
|
;; ?NO_BP, if defined, makes this the default.
|
|
;;
|
|
;; USE_BP can be specified on the cProc line
|
|
;; to force the generation of BP in equates.
|
|
;;
|
|
;; Moved definition of xxxxBASE. The equ was to
|
|
;; a forward reference.
|
|
;;
|
|
;; Don't generate a warning for a nogen if only
|
|
;; parameters are present.
|
|
;;
|
|
;; Keywords for cProc, cBegin, cEnd, and registers
|
|
;; are now allowed to be either all upper case or
|
|
;; all lower case.
|
|
;;
|
|
;; Only generate warnings on pass 2.
|
|
;;
|
|
;; 3.02 07/06/87 Walt Moore
|
|
;; Boy did I screw up <nogen> If the text is
|
|
;; recognized as nogen, then process it as such,
|
|
;; else ignore it and generate frame as needed.
|
|
;;
|
|
;; 3.03 07/14/87 Walt Moore
|
|
;; Added <partial> keyword to the cBegin macro
|
|
;; to only allocate locals and save registers.
|
|
;; Used in conjunction with dispatching in the
|
|
;; Winthorn engine and drivers.
|
|
;;
|
|
;; Added cleanframe macro which will take the
|
|
;; frame down, but not generate the RET statement.
|
|
;; Used in conjunction with dispatching in the
|
|
;; Winthorn engine and drivers.
|
|
;;
|
|
;; 3.04 07/16/87 Walt Moore
|
|
;; globalD was generating off and seg name
|
|
;; without word ptr override, giving them a
|
|
;; dword attribute
|
|

|
|
;; .xcref cleanframe
|
|
;;
|
|
;; 3.06 07/24/87 Hans Spiller
|
|
;; 32 bit small model (?SMALL32):
|
|
;; new entry exit sequences using pseudoregs
|
|
;; mach independant register names (IAX, etc)
|
|
;; parmI/localI (int size variables)
|
|
;; mpush/mpop uses mach independant names
|
|
;; IPUSHF, IPOPF, IPUSHA,IPOPA,IIRET
|
|
;;
|
|
;; case sensitivity bugfix. the compiler
|
|
;; generates "CODE", not "Code"
|
|
;;
|
|
;; 32 bit issues as yet undone: allocation
|
|
;; macros for dealing with 32 bit mode far
|
|
;; pointers, globalI, staticI, parmR, saving
|
|
;; si,di vs. esi,edi,ebx
|
|
;;

|
|
;; 3.06d 05/02/88 Andy Padawer
|

|
|
;; 3.06e 08/31/88 Andy Padawer

|
|
;;
|
|
;; 3.06f 05/12/89 Mark Roberts
|
|
;; fix staticI, globalDP and add globalI
|
|
;;
|

|
|
;; 3.06h 01/25/90 Jan de Rie
|
|
;; add ?DFCODE to allow suppressing code segments
|
|
;;
|
|
;; Assembly macros for interfacing to C
|
|
;;
|
|
;; User settable conditional assembly flags used within the cmacros
|
|
;;
|
|
;; Memory model flags. Set only one of the following. memS is the
|
|
;; default. The symbols with ? are for defining from the command line
|
|
;; and the memx symbols are numeric symbols that can be set in your source
|
|
;; file prior to including this file.
|
|
;;
|
|
;; ?SMALL memS - small model
|
|
;; ?MEDIUM memM - medium model
|
|
;; ?LARGE memL - large model
|
|
;; ?COMPACT memC - compact model
|
|
;; ?HUGE memH - huge model
|
|
;; ?SMALL32 memS32 - 32 bit small model
|
|
;;
|
|
;; ?DF Define flag. If this flag is 0, then defines default segment
|
|
;; and group definitions based on the compiler flag. If this
|
|
;; flag is 1, then does not define any segments or groups.
|
|
;;
|
|
;; ?DFDATA Define Data Flag. If this flag is 0, then defines default
|
|
;; data segment and group definitions based on compiler flag.
|
|
;; If this flag is 1, then does not define any data segments
|
|
;; or groups.
|
|
;;
|
|
;; ?DFCODE Define Code Flag. If this flag is 0, then defines default
|
|
;; code segments based on the compiler flag. If this flag is 1,
|
|
;; then does not define the code segments. Inactive if
|
|
;; ?DF is 1.
|
|
;;
|
|
;; ?TF Tight flag. If this flag is 0, then use longer epilog
|
|
;; sequence that safely cleans up a stack frame. If this flag is
|
|
;; 1, then use more efficient epilog that assumes the stack is
|
|
;; valid (SP)
|
|
;;
|
|
;; ?WIN Windows flag. Enables generation of special prolog/epilog
|
|
;; for far procedures. Default value is 1 (Windows).
|
|
;;
|
|
;; ?COW Character Windows flag. To be used in conjunction with ?WIN,
|
|
;; If defined will not save DS for ?NODATA far prolog/epilog
|
|
;; (CW does not modify the DS on the stack).
|
|
;;
|
|
;; DOS5 If defined, then special far prolog/epilog seqeuences will not
|
|
;; include the INC/DEC BP instructions.
|
|
;;
|
|
;; ?PLM Calling convention flag. If this flag is 0, then the
|
|
;; calling convention used is that of C. If this flag
|
|
;; is 1, then the PL/M calling convention is used.
|
|
;; The default value is 1. The PL/M calling convention
|
|
;; is used by pascal, fortran, basic, and cobol.
|
|
;;
|
|
;; In the C calling convention, arguments are passed
|
|
;; in reverse order; arg0 is the last pushed, argn is the
|
|
;; first pushed. also, it is the callers responsibility
|
|
;; to remove the arguments from the stack upon a return
|
|
;; from a call.
|
|
;;
|
|
;; In the PL/M calling comvention, arguments are passed
|
|
;; as encountered; arg0 is the first pushed, argn is the
|
|
;; last pushed. also, it is the called procedure's
|
|
;; responsibility to remove parameters from the stack
|
|
;; before returning (using the RET n instruction)
|
|
;;
|
|
;; ?NODATA If defined, then no data segment or DGROUP is defined and
|
|
;; the special prolog/epilog sequences will not contain the
|
|
;; code needed to setup DS.
|
|
;;
|
|
;; ?CHKSTK If defined, then prolog sequences for cProcs with local
|
|
;; parameters will call the CHKSTK procedure to allocate
|
|
;; the stack space.
|
|
;;
|
|
;; ?CHKSTKPROC If defined, then this macro will be invoked to
|
|
;; perform the stack checking, otherwise the
|
|
;; standard stack checking procedure will be
|
|
;; performed. ?CHKSTKPROC must be declared
|
|
;; before the cmacros are included in the source
|
|
;; else the standard chkstk routine will be declared
|
|
;; as an external symbol.
|
|
;;
|
|
;; On entry to the user's stack checking procedure,
|
|
;; the frame has been setup except for allocating
|
|
;; local variable space and saving autosave registers.
|
|
;;
|
|
;; The user supplied macro is passed as an argument
|
|
;; the number of byte of stack space requested.
|
|
;;
|
|
;; ?PROFILE If defined then all far cBegin entries will have StartNMeas,
|
|
;; and all cEnd will have StopNMeas calls, StartNMeas and
|
|
;; StopNMeas will be defined as externfp
|
|
;;
|
|
;; ?NOPARMR If defined, then the "parmR" macro will not be defined.
|
|
;;
|
|
;; ?NOGLOBAL If defined, then the "globalx" macros will not be defined.
|
|
;;
|
|
;; ?NOSTATIC If defined, then the "staticx" macros will not be defined.
|
|
;;
|
|
;; ?NOEXTERN If defined, then the "externx" macros will not be defined.
|
|
;;
|
|
;; ?NOLABEL If defined, then the "labelx" macros will not be defined.
|
|
;;
|
|
;; ?NODEF If defined, then the "defx" macros will not be defined.
|
|
;;
|
|
;; ?NOPTR If defined, then "farptr & regptr" will not be defined.
|
|
;;
|
|
;; ?QUIET If defined, then only error messages will be issued to
|
|
;; the console. If undefined, then certain cmacro text will
|
|
;; be generated to the console.
|
|
;;
|
|
;; ?NOATOMIC If defined, then ATOMIC will be ignored (for giving real
|
|
;; frames to all procedures (and profiling).
|
|
;;
|
|
;; ?NO_BP If defined, then equates generated for parms and locals
|
|
;; will not explicitly reference BP.
|
|
;; IAX, ICX, IDX, IBX, ISP, IBP, ISI, IDI
|
|
;; these pseudo registers expand to either ax..., or eax...
|
|
;; depending upon 32bit mode being enabled. they should be
|
|
;; used whenever a pointer or integer is being used in order
|
|
;; to make source code machine independant

;; ?pp1 is the macro that generates the text equate for the
|
|
;; parameter. Two options exist, one for the C calling
|
|
;; convention where the last parameter was the first pushed onto
|
|
;; the stack ('C' convention), and one for the PL/M calling
|
|
;; convention where the first parameter was the first
|
|
;; pushed (also the same as ms-pascal).
|
|
;;
|
|
;; The text generated will be of one of two forms:
|
|
;;
|
|
;; name equ (type ptr [bp+(adj+offset)]) for C
|
|
;; or
|
|
;; name equ (type ptr [bp+adj+?po-offset]) for PL/M
|
|
;;
|
|
;;
|
|
;; For C, since parameters are pushed first last, the offset
|
|
;; plus the adjust will point to the correct parameter.
|
|
;;
|
|
;; For PL/M, since parameters are pushed first first, the offset
|
|
;; of a parameter is much more complicated. A known portion of
|
|
;; the offset can be computed when the text equate is generated.
|
|
;;
|
|
;; What is known is the number of garbage bytes between BP and
|
|
;; the nearest parameter (in this case the last parameter), and
|
|
;; also how many bytes of parameters have preceeded this parameter.
|
|
;;
|
|
;; What is unknown is how many total bytes of parameters there will
|
|
;; be, which affects all the generated text equates since the offset
|
|
;; from bp must be determined at some point.
|
|
;;
|
|
;; Well, the offset from BP can be computed with one variable if
|
|
;; the following is remembered:
|
|
;;
|
|
;; the offset of any parameter from the first parameter is always
|
|
;; the current parameter offset (?po).
|
|
;;
|
|
;; With this in mind, you just have to figure out where the first
|
|
;; parameter is, which is:
|
|
;;
|
|
;; bp + garbage adjustment + distance to first parameter
|
|
;; or
|
|
;; bp + ?adj + ?po
|
|
;;
|
|
;; This implies that any parameter can be defined as:
|
|
;;
|
|
;; bp + ?adj + ?po -%?po
|
|
;;
|
|
;; Make any sense?
|
|
;;
|
|
;; For PL/M, a chain of self-purging macros will be generated
|
|
;; which will pass the evaluated ?po to any previous incarnation
|
|
;; of the macro. This will allow the text equate to be generated
|
|
