- This is the changes file, that explains what has changed over the
- revisions: current revision "2.0"
-
- 1.0 - Original <released but never really spreaded>
-
- 1.1 - Changed a lot of for( ... < ...) into for( ... != ...)
- Corrected a hilarious bug in err_undefs. (Missing { }). How
- did NASM65 ever work without those ??
- Added noisy tokenizer for TOS version. (Nat!/1991)
-
- -- INBETWEEN -- <start>
- 1.0:- Patch for bug that was intermittently corrected in 1.1 (Nat!/1991)
- ^-----{ NOTE!
- -- INBETWEEN -- <end>
-
- 1.1 - Improved int_suckin a bit. Also directive_suckin.
-
- 1.2 - Deimproved some code, made it MSDOS portable. Heavy optimization
- work did strangely enough not pay off anywhere (don't ask me why)
- on paper it looked quite substantial.
- Streamlined I/O further, fixed some bugs in support programs.
- Now forward branches that go over the top give at least a hint,
- where the branch might have been (doesn't work well with macros
- includes and the like).
-
- 2.0 Argh! This is already v2.0, a few additions I needed to incorporate
- to 'effortlessly' assemble FTOE (my own gigantic game (har har))
- unfortunately forced a major redesign in the object module
- structure. .DS now creates holes in the binary instead of
- just dropping zeroes. For Display lists and other stuff which
- should lie on page boundaries an -a option has been added.
- (Sorry no GC yet -> 3.0). Some code has been de-inlined to get the
- assembler to a targeted < 50K. More bugfixes than I hoped would
- be neccessary (probably added quite a lot with this version).
- A selection:
- Numerous bugs and improvements in support programs
- more_space -- only worked for two segments
- clean_labels -- did not clean labels
-
- Made the assembler much more usable by countless bug fixes and
- improvements.
-
- FOR A REAL RELEASE, VERSION WILL BE SET BACK TO 1.0
-
- 1.0 UNIX portability apparently achieved. Looks good right now.

- ---------------------------------------------------------------------------
- 23.Nov.1991: added REPT to the list of directives. added NASM as an (unused)
- enveloping program. No bug fixes! (looks good right now). Improved
- makefiles and the like
-

- NLINK65 v1.2
- NLIB65 v1.0
- ---------------------------------------------------------------------------
- 29.Dez.1991: recompiled with PURE-C, beautified it up a bit source code
- wise
- NASM65 v1.5
- NLINK65 v1.3
- NLIB65 v1.1
- ---------------------------------------------------------------------------
- 16.Jan.1992: Added ARGV support via PCVSTART.O, made AMIGA
- compatibilty changes thanx to dinadan@mcshh.hanse.de
- NASM65 v1.6 Fixed a typing error in code.h for PHILOSOPHICAL
- NLINK65 v1.4 code. Fixed filename extension memory clobber bug
- NLIB65 v1.2 Object files made prettier a bit. Dinadan fixed two
- DISASM65 v1.7 bugs (one each) in XTRCTBIN & CHKFFFF. Fixed one bug
- XTRCTBIN v1.1 in MD_SUCK (for 680[234]0 machinery)
- DEMAC65 v1.4 XTRCTBIN now (hopefully) converts Atari binaries into
- CHKFFFF v1.1 C64 & AppleII binaries. UNIX portablity achieved
- yet once again (har har). Cut filenames in error
- messages. Added C64 and AppleII to disassembler.
-
- ---------------------------------------------------------------------------
- 18.Sep.1992: Fixed 'date' bug in "changes.txt" for last rev. (har)
- Fixed two really atrocious bugs.
- Fixed one lame (but TOUGH to trace down) nfree()
- bug.
- To remain compatible with some bogus 32-bit
- NASM65 v2.0 compilers, I needed to incorporate a change in the
- NLINK65 v2.0 filestructure. This means that the object files go
- NLIB65 v2.0 downwards incompatible from now on!! This also gave
- DISASM65 v1.8 me the chance to increase the identifier length in
- XTRCTBIN v1.2 the object table to 32 characters. You PASCAL-
- DEMAC65 v1.5 like coders, can now write (and link)
- CHKFFFF v1.2 THIS_VARIABLE_COUNTS_MICE .byte 2
- CRLF155 v1.7 THIS_VARIABLE_COUNTS_SHEEP .byte 234
-
- (It should be possible, that) old objects can be extracted from libraries,
- but old objects can not be added. Due to an error in the library code,
- libraries generated on INTEL (BIGENDIAN) machinery were never compatible.
- This has been fixed.
- Unfortunately for those users downward compatibility has been lost!
-
- Made a full hearted attempt at providing PC compatibility. Since that
- system sucks even more than previously suspected, I can't make any
- guarantees about stability. As soon as the PC goes to 32-bit, this should
- work just dandy. My once beautiful source has been now littered with
- 'huge' pointers, ridiculous casts and other kludgey stuff.
-
- Again to the port to MSDOS. Everything seems to work except the damned
- linker. TC3.0 couldn't deal with huge pointers correctly and TC2.0 (I
- dunno) code chokes somewhere, sometime unpredictably. I think this is
- fixed now with the nfree() fix.
