- The ASxxxx assembler and linker have been updated to move
- byte index, direct page mode, and byte pc relative address
- checking from the assembler to the linker. This change has al-
- lowed the following enhancements:
-
- 1. The .setdp directive now has a common format for all
- AS68xx assemblers.
-
- 2. Direct page variables may be externally defined with
- their addresses resolved at link time.
-
- 3. Byte index offsets may be external references and
- resolved at link time.
-
- 4. Byte pc relative instructions (i.e. branches) may
- reference external labels or labels in other areas.
-
-
- The ASxxxx assemblers (using the -f or -ff option) can
- generate a listing file which flags the data that will be relo-
- cated by the linker.
-
- The REL file format now has an additional directive for pag-
- ing information and has additional flags for page0, page, and
- unsigned byte formats. The new linker is compatible with the
- first version of the ASxxxx assemblers.
-
- The remaining changes are related to non-portable code found
- while porting the assemblers to a motorola 68030 system.
