Summary of changes/additions to the ASxxxx Assemblers from Ver- sion 5.11 to Version 4.11. 2015_06_27 Version 5.10 Update 1 This update for Version 5.10 of the ASxxxx Cross Assemblers includes fixes for the following errors: (1) The as6500 assembler incorrectly assembled cpx # and cpy # instructions. (2) An error in asmain.c inhibited the listing of all .if.. assembly directives. 2014_10_31 Version 5.10 (1) Rewrite of listing to relocated listing translation code in the assembler and the linker base code. The Assemblers now create a .lst to .rst hint file with the extension .hlr (when both .lst and .rel files are created by the assembler). (2) Add as6100 assembler (Intersil IM6100 / Harris HM6100) (3) Add as78k0s assembler (Renesas/NEC 78K/0S) 2013_05_12 Version 5.00 Update 6 This update for Version 5.00 of the ASxxxx Cross Assemblers rolls up updates 1, 2, 3, 4, and 5 with fixes for the following: (1) Fix asscmp assembler (pre-increment on fetch). (2) Fix aslink error reporting for PC relative modes. 2012_08_01 Version 5.00 Update 5 Update_05 for the ASxxxx Assembler and Linker Version 5.00 (use 'pkunzip -d u05500.zip' for extraction with MS-DOS) (use 'unzip -L -a u05500.zip' for extraction with Linux) See the note about merging this update with the asxv5pxx distribution. This update for Version 5.00 of the ASxxxx Cross Assemblers rolls up updates 1, 2, 3, and 4 with the addition of a new assembler and fixes: (1) A new cross assembler for the Fairchild F8 microprocessor (or Mostek 3870). (2) Minor syntactical changes for ANSI C compatability, fix type conversion warnings, and update the various build, make, and test files. Update 4 Items (1) The AS8048 base opcode value for the JMPP instruction should be B3 and NOT 83. (2) The AS8051 assembler calculates incorrect offsets when using the program counter, ".", as a destination in the instructions having a PC-Relative addressing mode. These instructions include: jbc, jb, jbn, jc, jnc, jz, jnz, cjne, and djnz. Update 3 Items (1) A new cross assembler for the Fairchild F8 microprocessor (or Mostek 3870). (2) Minor syntactical changes for ANSI C compatability, fix type conversion warnings, and update the various build, make, and test files. (3) New cross assemblers for STMicroelectronics ST6, ST7, and STM8 microprocessors. (4) An ASlink list file update error fix (-u option) causing some errors not to be inserted into the created .rst file. (5) An additional ASxxxx assembler option (-v) which enables checking for out of range signed / unsigned values in symbol equates and arithmetic operations. This option has some ambiguities as internally the assemblers use unsigned arithmetic for calculations. (e.g. for a 2-byte machine -32768 and 32768 are both represented as 0x8000) Update 2 Items (1) When using the assembler directive .end to specify the code entry address the assembler fails to set the variable .__.END. as a global. Therefor the value of .__.END. is not passed to the linker and the start address frame is always zero. (2) The linker will fail to create a start address frame when there is no code generated within the area/bank referenced by the .__.END. variable. Update 1 Items (1) The newest versions of gcc (and perhaps other compilers) give warnings about missing arguments in the fprintf() function. This update replaces fprintf(arg1, arg2) with fprintf(arg1, "%s", arg2) in each affected line of code. (2) The newest versions of gcc (and perhaps other compilers) have defined 'getline' as a standard function in 'stdio.h'. This conflicts with the function 'getline()' in the ASxxxx package. All references to 'getline()' have been changed to 'nxtline()'. Before merging the asxv5pxx directory and subdirectories with the V5.00 distribution the following files/directories must be deleted: [asxv5pxx\asf2mc8\f8mch.c [asxv5pxx\asf2mc8\f8adr.c [asxv5pxx\asf2mc8\f8pst.c [asxv5pxx\asf2mc8\f8.h [asxv5pxx\asxmak\vc6\asf2mc8] [asxv5pxx\asxmak\vs05\asf2mc8] 2011_07_24 Version 5.00 Update 4 This update for Version 5.00 of the ASxxxx Cross Assemblers includes fixes for the following errors: (1) The AS8048 base opcode value for the JMPP instruction should be B3 and NOT 83.

(2) An ASlink list file update error fix (-u option) causing some errors not to be inserted into the created .rst file. (3) An additional ASxxxx assembler option (-v) which enables checking for out of range signed / unsigned values in symbol equates and arithmetic operations. This option has some ambiguities as internally the assemblers use unsigned arithmetic for calculations.

Therefor the value of .__.END. is not passed to the linker and the start address frame is always zero. (2) The linker will fail to create a start address frame when there is no code generated within the area/bank referenced by the .__.END. variable. Update 1 Items (1) The newest versions of gcc (and perhaps other compilers) give warnings about missing arguments in the fprintf() function.

(2) The newest versions of gcc (and perhaps other compilers) have defined 'getline' as a standard function in 'stdio.h'. This conflicts with the function 'getline()' in the ASxxxx package. All references to 'getline()' have been changed to 'nxtline()'. 2010_04_01 Version 5.00 Update 2 This update for Version 5.00 of the ASxxxx Cross Assemblers includes fixes for the following errors: (1) When using the assembler directive .end to specify the code entry address the assembler fails to set the variable .__.END. as a global. Therefor the value of .__.END. is not passed to the linker and the start address frame is always zero. (2) The linker will fail to create a start address frame when there is no code generated within the area/bank referenced by the .__.END. variable. 2010_03_03 Version 5.00 Update 1 This update for Version 5.00 of the ASxxxx Cross Assemblers includes fixes for the following errors: (1) The newest versions of gcc (and perhaps other compilers) give warnings about missing arguments in the fprintf() function. This update replaces fprintf(arg1, arg2) with fprintf(arg1, "%s", arg2) in each affected line of code.

All references to 'getline()' have been changed to 'nxtline()'. 2009_04_01 (Version 5.00) Added a general purpose macro processor to the ASxxxx assem- blers. Added true (t), false (f), and true or false (tf) condition- als to the .if / .else / .endif construct. The conditionals .ift, .iff, and .iftf allow replacement of the .else directive making the .if / .endif construct more readable. e.g. .ift if condition is true An alternate .if construction has been added to the ASxxxx assemblers: e.g. .if eq,... if argument == 0 The immediate conditional statements have been added to the ASxxxx assemblers. These conditionals can replace the .if / ... / .endif construct for a single assembler source line: e.g. .iifeq arg label: .word 0x1234 The alternate immediate conditional statements have also been added to the ASxxxx assemblers: e.g. .iif eq,arg label: .word 0x1234 The listing options for the ASxxxx assemblers has been up- dated to enable/disable any of the following parameters from be- ing output to a generated listing file: err error codes loc code location bin assembler binary code eqt symbolic equates / if evaluations cyc machine cycles lin assembler source line number src assembler source code pag paging control lst listing of .list / .nlist md macro definition me macro expansion meb macro expansion binary code ! sets the listing mode to !(.list) or !(.nlist) before applying the sublist options e.g. .nlist (lst,pag) ; disable .list/.nlist listing ; and pagination The NOT parameter, !, is used to set the listing mode to the opposite sense of the .list or .nlist directive. For example: .nlist (!) is equivalent to .list and .list (!) is equivalent to .nlist To enable listing and simultaneously disable the cycle count use the directive: .nlist (!,cyc) or if you wish to suppress the listing of the .list / .nlist directives: .nlist ; disables all listing .nlist (!,lst) ; enables all listing except : .list (...) and .nlist Normally the .list and .nlist directives are not evaluated when encountered within a FALSE conditional block. This default behavior can be modified by specifying a non zero argument in the .list or .nlist directive: .nlist 1,(!,lst) ; enables listing even within ; a FALSE conditional block The .bndry assembler directive has been added to ASxxxx. The .bndry directive changes the current location address to be evenly divisible by a specified integer value. e.g. .org 0 .bndry 4 ; . == 0 .org 1 .bndry 4 ; . == 4 2009_02 Added the Cypress PSoc (M8C) ASM8C assembler to ASxxxx. 2008_09 Added the 8048 (8021, 8022, and 8041) AS8048 assembler to Asxxxx. 2008_02 Added the SC/MP ASSCMP assembler to ASxxxx. 2008_02_03 (Version 4.11 Update 4) An update to the AS2650 assembler to fix the following errors: 1) The indexed addressing mode generates invalid code by using the first argument register as the index register: (addr = 0x1234) loda r0,[addr,r1] 0C F2 34 this should give 0D F2 34 2) The index addressing mode did not generate an addressing error when the first argument register was not r0: stra r1,[addr,r2] should give an error, the source must be r0 loda r2,[addr,r3] should give an error, the destination must be r0 3) The S2650 auto increment and decrement indexing modes always perform the register update before the register is used. i.e. +Rn or -Rn. The assembler now accepts +Rn or Rn+ as meaning pre-increment and -Rn or Rn- as meaning pre-decrement. The AS2650 assembler tstscn files have been updated for testing the assemblers. 2007_10_21 (Version 4.11 Fix) In the AS6816 assembler the instruction ANDP gives wrong object code. Changed from 37 2A to 37 3A. 2007_04_01 (Version 4.11 Update 3) An update to the ASPIC assembler and associated fix to ASLINK: 1) Change the pic addressing to lo/hi from hi/lo byte ordering. 2) The update fixes an error in the pic17 series LCALL instruction. 3) A rewrite of the pic18 series assembler to change the PC addressing from 1 per 16-bit word to 1 per 8-bit byte and add the extended instruction set. 4) Modify the Linker Merge Mode processing to take into account the discarded low order bits for PC Relative Addressing. 5) New tstscn files for testing the assemblers. 2006_11_01 (Version 4.11 Optional Update 2) 1) OS9 definition files and an OS9 assembler module which creates the OS9 header, code and data areas, and the module CRC block: os9_mod.def OS9 Module Definitions os9_sys.def OS9 Sytem Definitions os9_mod.asm OS9 Module Begin / End Code 2) a program, s19os9, to post-process assembled OS9 modules in S19 format into binary OS9 modules with the appropriate header checksum and module CRC values calculated. 3) new make and project files which may be used to compile the s19os9 program. 2006_11_01 (Version 4.11 Optional Update 01) The .list and .nlist directives are now modified by .if / .else / .endif processing so that they are active only in a TRUE clause. The .page and .include directives are now modified by the .list and .nlist directives so that pagination occurs only when listing is active. The new default functionality for the .list, .nlist and .page directives may be modified by including an optional argument in the directive as shown here for the the .list directive: .list arg a non-zero argument invokes the directive irrespective of the .if / .else / .endif status. 2006_07_26 (Version 4.11 Patch 01) The assembly of a direct page instruction with a numeric constant causes a program crash when a .rel file is created. e.g.: andb *0x02 The use of a symbolic constant or symbol plus a a constant compiles normally. val = 0x02 andb *val andb *extern+0x01 The assemblers effected are: as6809 as6812 ash8 aspic Summary of changes/additions to the ASxxxx Assemblers from Version 4.10 to Version 4.11. 1. Incorporated the patches contained in p01410.zip which corrected a coding error that affected BANKS containing multiple ABS areas or mixed AREA types. 2. Incorporated the patches contained in p02410.zip which corrected improper use of R_USGN in most addressing modes in AS6500. This caused unexpected errors in V4.xx because of the ASxxxx core change to 32-bit in- tegers and arithmetic. 3. Incorporated the patches contained in p03410.zip which corrected errors in the .local and .globl assembler directive processing routine that introduced unwanted side effects for variable and symbol definition files. These effects included improper definitions and incor- rect error warnings. 4. The following new subdirectories and their files have been added to the asxtst directory: * areabank Area and Bank Processing Test This directory contains several test programs: ts.asm (single file - multiple areas), tm1.asm and tm2.asm (multiple file - multiple areas), and tbm.asm, tbm1.asm, and tbm2.asm ( multiple file - multiple areas within a bank) and several other files which verify the correct operation of the linker when used with a single linked file, multi- ple linked files having no banking, and multiple linked files with banking. These reference files show in detail how the .area and .bank directives work together. * equtst Equate Processing Test This directory contains a test file for verifying the operation of the .globl, .local, .equ, .gblequ, and .lclequ directives and the =, ==, and =: equalities. * inctst Nested Include File Test * itst Include File Error Reporting Test 5. Incorporated the updates contained in u01410.zip which added 10 undocumented 8085 instructions to the AS8085 assembler. 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. 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. 7. 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. 8. Problem: Aslink creates output files for banks with no output data. Fix: Aslink now deletes any created output file for banks with no data. 9. 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. 10. Incorporated the patches contained in p02400.zip for file ds8adr.c to correct for an error in the direct page addressing mode of AS8xCxxx. 11. Incorporated the patches contained in p03400.zip for file rabmch.c to correct for an error in the processing of the "ret cc" instruction. 12. Made many corrections to internal code comments.
