This update for Version 4.11 of the ASxxxx Cross Assemblers includes 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: (assume 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 'a' error, the source must be r0 loda r2,[addr,r3] should give an 'a' 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. Merge the update asxv4pxx directory and subdirectories with the V4.11 distribution. The following files will be overwritten: [asxv4pxx/as2650] s26adr.c s26mch.c t2650.asm t2650e.asm [asxv4pxx\asxxhtml] asxupt.htm You must recompile the AS2650 assembler to incorporate the update. *---*---*---*---*

This update for Version 4.11 of the ASxxxx Cross Assemblers includes 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.

This update for Version 4.11 of the ASxxxx Cross Assemblers includes: 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. Merge the update asxv4pxx directory and subdirectories with the V4.11 distribution. Note: It is recommended that Optional Update 01 also be installed to update the default pagination behavior of the ASxxxx Assemblers .list, nlist, .page, and .include directives. Prepare your OS9 module as described in os9_mod.asm. os9_mod.asm contains a working OS9 module which can be built using the included module.asm and bldmod.bat files. Once you have assembled your module into an s19 file use the program s19os9 to create the binary OS9 module file. The program s19os9 is invoked from the command line: s19os9 mod.s19 -o mod.bin where mod.s19 is the input s19 file and mod.bin is the os9 binary output file. The following OS9 Driver assembler program shows the steps required when creating an OS9 Driver using the os9_mod.asm file. os9_mod.asm loads the os9_mod.def and os9_sys.def files, defines the software interrupt macro os9, and creates the os9 driver header and crc blocks. ;**** ; Step 1: ; Use the .define assembler directive ; to insert the parameters into the ; os9_mod.asm's header structure. ; ; Note: See the file os9_mod.asm for ; parameter names and definitions. ; .define OS9_ModNam, "LSTNAM" .define OS9_Typ, "PRGRM" .define OS9_Lng, "OBJCT" .define OS9_Att, "REENT" .define OS9_Rev, "1" .define OS9_ModExe, "LSTENT" .define OS9_ModMem, "LSTMEM" ; Step 2: ; Set the symbol OS9_Module equal to 1 ; and .include the file os9_mod.asm.

This update for Version 4.11 of the ASxxxx Cross Assemblers modifies the functionality of the .list, .nlist, .page, and .include directives. 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 .list directive: .list arg a non-zero argument invokes the directive irrespective of the .if / .else / .endif status. Merge the update asxv4pxx directory and subdirectories with the V4.11 distribution. The following files will be overwritten: [asxv4pxx\asxxsrc]: asexpr.c aslex.c aslist.c asmain.c asout.c asxxxx.h [asxv4pxx\asxxhtml] asxupt.htm You must recompile all the ASxxxx assemblers to incorporate the update.

ASxxxx: 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 constant compiles normally. val = 0x02 andb *val andb *extern+0x01 The assemblers effected are: as6809 as6812 ash8 aspic Merge the patch asxv4pxx directory and subdirectories with the V4.11 distribution.
