Macro freezing Poasm

(1/1)

Vortex:
Hi Pelle,

Poasm is freezing while trying to assemble the code below. The assembler does not return back the control to the command prompt. The problem is the retx macro :


--- Code: ---PUBLIC start

ExitProcess PROTO :DWORD

includelib \PellesC\Lib\Win64\kernel32.lib

retx MACRO

     db 0C3h

retx ENDM
 
.code

start:

    mov     rcx,20
    mov     rdx,10
    call    main
    invoke  ExitProcess,0

OPTION PROLOGUE:NONE
OPTION EPILOGUE:NONE

main PROC

    mov   rax,rcx
    add   rax,rdx
;   ret           ; ret is ignored
    retx          ; Poasm is freezing
                  ; at this point
;   db    0C3h

main ENDP

OPTION PROLOGUE:PrologueDef
OPTION EPILOGUE:EpilogueDef

END

--- End code ---

Test with Poasm Version 12.00.1

Hello,

The retn instruction is the best option to terminate the procedure but the assembler should not freeze as I mentioned in my first posting.


--- Code: ---PUBLIC start

ExitProcess PROTO :DWORD

includelib \PellesC\Lib\Win64\kernel32.lib

retx MACRO

     db 0C3h

retx ENDM
 
.code

start:

    mov     rcx,20
    mov     rdx,10
    call    main
    invoke  ExitProcess,0

OPTION PROLOGUE:NONE
OPTION EPILOGUE:NONE

main PROC

    mov   rax,rcx
    add   rax,rdx
    retn

main ENDP

OPTION PROLOGUE:PrologueDef
OPTION EPILOGUE:EpilogueDef

END
--- End code ---

Pelle:
I will look at it...

Pelle:
This seems easily fixed by using the correct syntax:

--- Code: ---retx MACRO
     db 0C3h
ENDM

--- End code ---
