NewSphinxCmm Examples

[Emil_halim]

Hi all,

Here is an other Example that showing you how to mix C-- & Masm codes.

NoteWell:
=======
1-  NewSphinxC extended the extern keyword so that it will accept an external block of decelerations.

Code Select Expand


extern {
  cdecl GetStrLen();   // declares external function
  cdecl Ten();             // declares external function
  byte  buffer;            // declares external data
  byte  hw;                // declares external data
}
   

2- using  EXTERNDEF keyword in Masm block to external data of function those declared outside Masm code block and you entend to use them in Masm block.

3- the Masm code block started with .model  directive  with term 'c' which is a calling convention.

4- MasmPlgIn allows some c-- features with masm code blcok .

Hi All,

Here is another Example that mix SphinxC and HJWasm.

some roles you have to care of.

1- masm block of code must started with term '^^' and end with the same term.
2- masm bolck will extract from sphinxc then compile and later linked with alink.
3- this process will accomplished by MasmPlgIn , you have not use the cpu directive.
4- MasmPlgIn will specify tha path of include directory.
5- take care of function call convention , it may crash your code.


the next masm code was taken from http://www.masmforum.com/board/index.php?topic=14696.105
it determines the cpu of computer.

Hi all

Here is the cmm version of Michael Webster's code timing macros.http://masm32.com/board/index.php?topic=49.0

I have converted to CMM, there was a small problem when i tried to do that.

the problem is , how to put the code in-between the 2 CMM macro and let it works just like masm code. i uesd a trick , which is that at the end of first macro i puted this code

Code Select Expand


        call label
    @label:                              /* Start test loop                             */   
      ?aligncode  16                     /* Optimal loop alignment for P6               */   
   

it push the current address in the stack . and puted this in the front of second macro

Code Select Expand


         dec  __counter__loop__counter__
        jz    @F
        jmp DSDWORD[ESP];
     
      @@:
        ESP += 4;

so it jumps to the end of first macro if the counter is greater than zero.

Here is the macros [ cntrcmm.inc ]

Hi All

MOV vs PUSH ticks comparison from http://masm32.com/board/index.php?topic=6324.0

so , this converted example shows you that how it is so easy to convert masm code to NewSphinxCmm then using CMM stunning features.

Hi all,

Hi All,

This demo will show you that , how it is so easy to create Function Address Table which holds the address of functions then later you can call them in a certain order.

also it shows you how to code the same function in many deferent syntax way , such as c style , asm style , c-- style .......

finally it shows you how easy to make a benchmark test to see the deferent speed of some cods.

Hi ALL,

To use ilink32 of Borland , just first download a BorlandC++ trail version in your system.

then try the next Example , needs NewSphinxCmm version 256.

Hi ALL,

In this Demo i have changed the  __acrtused procedure in the c0nt.asm to be like that

Code Select Expand


;----------------------------------------------------------------------
; Startup code

EXTRN           cmmstratup:NEAR  ; Added By Emil Halim

_TEXT           SEGMENT  DWORD USE32 PUBLIC 'CODE'

                public __acrtused
__acrtused      PROC NEAR   

                jmp   cmmstratup              ; Added By Emil Halim                 
                               
__acrtused      ENDP



then OnExit directive will assemble it with tasm32 see below.

also i remove the underscore from _main so that it will call CMM main.

so the cmmstratup cmm code holds the startup code , you can modify it as you wish.

Here is the CMM demo
