Summary of changes/additions to the ASxxxx Assemblers from
Version 4.00 to Version 4.10.
1. Added new assemblers for the Zilog EZ80, Zilog Z8, Sig-
netics 2650, and Fujitsu F2MC8(L,FX) processors.
2. Added the processor cycle count option (-c) to all pro-
cessors.
3. Several of the assemblers (ASZ80, ASRAB, AS6805,
AS6808, AS6812, ASF2MC8, ...) now support subsets or
supersets of their basic opcodes by the use of assem-
bler specific directives.
4. Added .ifeq, .ifne, .iflt, .ifgt, .ifle, and .ifge con-
ditional assembly directives.
5. Added support for the Tandy Color Computer Disc Basic
binary file format to ASLINK.
6. Updated the assembler and linker source code to support
16-Bit and 32-Bit compilers. Tested with Borland Turbo
C++ 3.0 and Symantec 7.2 C/C++ 16-Bit compilers, and
with Visual C++ 6.0, Cygwin, DJGPP V02.03, and Linux
32-Bit compilers.
7. Problem:
When an area size is equal to the 'address space size'
the size parameter is reported as 0. (A normal condi-
tion caused by address rollover to 0.) Aslink inter-
preted this as a 0 size.
Fix:
A new area 'Output Code Flag' bit was defined to indi-
cate when data is defined in an area. ASxxxx and
Aslink have been updated to set and process this area
flag bit.
8. Problem:
The use of the .end assembler directive in an Asxxxx
assembler would cause Aslink to output the optional
start address in all output files.
Fix:
Updated Aslink to output the optional start address
only in the output file associated with the area/bank
containing the .end directive.
9. Problem:
Aslink creates output files for banks with no output
data.
Fix:
Aslink now deletes any created output file for banks
with no data.
10. Incorporated the patches contained in p01400.zip for
files t1802.asm and 1802pst.c to correct for an error
in the opcodes generated for the BM, BL, and BNF
mnemonics.
11. Incorporated the patches contained in p02400.zip for
file ds8adr.c to correct for an error in the direct
page addressing mode of AS8xCxxx.
12. Incorporated the patches contained in p03400.zip for
file rabmch.c to correct for an error in the processing
of the "ret cc" instruction.
13. Made many corrections to internal code comments.
