CW6.3 Assembler - Problem with conditional assembly directives

[bigmac]

Hello all,

CW assembler has a rich set of conditional assembly directives.  I typically would utilize something like the following construct to prevent the multiple definition of a particular label -

  ifndef  LABEL_NAME

LABEL_NAME  equ  <expression>

  endif

  ifndef  LABEL_NAME

LABEL_NAME:

  [<assembly instructions, macros, data, etc>]   ; Optional

  endif

These examples seem to work just fine.  However, the problem seems to be when the label refers to a macro definition.  The label name remains undefined, resulting in error messages about duplicate macro definitions.

  include "908_macros.inc"    ifndef  ILOP ILOP:     MACRO     ; Reset MCU using illegal opcode          DC.B  $8D          ENDM  endif

 The above does not work if the macro is also defined with the file "908_macros.inc".  The only work-around that I so far have been able to find, is to create a dummy label, in addition to the macro name.

  include "908_macros.inc"    ifndef  _ILOP _ILOP:    ; Reset MCU using illegal opcodeILOP:     MACRO          DC.B  $8D          ENDM  endif

However, in addition to being unwieldy, this method becomes problematic should the include be not modifiable to provide the dummy variable, e.g. such as "derivative.inc".

I wonder if others, who make extensive use of assembly macros, have previously encountered this problem, and perhaps have an alternative "fix".  Maybe this is a bug in the assembler, that has never been fixed, or perhaps this was intentional in the design of the assembler.

Regards,

Mac

As you, I'm facing the same problem since many years ago... I always need to create a label for every macro definition. That's in CW 3.1, 4.6 and also 6.1

Maybe a solution or fix can help us both!
