-DefLabel: Improves support for data allocation directives

Group

Input

Scope

Assembly Unit

Syntax

  -DefLabel

Arguments

None

Default

None

Description

Improves support for data allocation directives. On passing this option, the data directives (not associated to any label) get associated with previous defined labels (if exists). This inhibits the emission of temporary variables ( VARx) by assembler.

Example

The following listing shows the example for the -DefLabel.

Listing: Example -DefLabel


MySection: SECTION
TTab_TIT_45:    ; Modo 5

       DC.B    $FF,$FF,$FF,$FF,$FF,$FF,$FF,$FA,$90,$20,$00,$01,$4F,$FF

       DC.B    $C1,$FF,$FF,$FF,$FF,$FF,$FF,$F7,$64,$88,$00,$14,$BF,$FF
,$F5,$FF,$EF,$B8,$3F,$FE

       DC.B 5

       DC.W 3

mainLoop:

            RTS

With 
-DefLabel option 
OFF:

Output:

9-VAR00001         0   14 LOCAL FUNC      9 (MySection)

10-VAR00002       14   14 LOCAL FUNC      9 (MySection)

11-VAR00003       28   1 LOCAL  FUNC      9 (MySection)

12-VAR00004       29   3 LOCAL  FUNC      9 (MySection)

With 
-DefLabel option 
ON:

Output:

9-TTab_TIT_45      0   29 LOCAL FUNC      9 (MySection)

10-VAR00001        29  3  LOCAL FUNC      9 (MySection)

The input file when assembled with option -DefLabel, allocates the DC.B directives to symbol TTab_TIT_45 and DC.W to dummy variable VAR00001.
