Changelog for v3.2 release

  • added algorithm to deduplicate consecutive data lines in formatted disassembly (greatly reduces disassembly size for data objects)
  • removed TESTING label for some code blocks that have proven themselves to be useful and stable
  • applied minor updates to object hints (MK2.EXE, PACMANVR.EXE)

Changelog for v3.1 release

  • added algorithm to rename duplicate globals to avoid name clashing (unique labels are important/helpful when trying to recompile disassembly as one huge blob)
  • added support for loop instruction (treated like call/jumps, i.e. loop targets contribute to branch analysis and are replaced with labels in formatted disassembly)
  • added script to compile wcdatool using Cython (no performance gain yet as wcdatool's Python sources have not yet been decorated/optimized for Cython)
  • fixed minor copy&paste mistake (references to non-existing variables in module_miscellaneous.py)
  • updated object hints for Pac-Man VR
  • overhauled a number of comments (clarification/updates/typos)
  • added wcdatool's usage information to README.md
  • applied a number of minor changes to README.md

Changelog for v3.0 release

  • added support for TBYTES (thanks to halamix2 for adding to this) (e.g. FATAL.EXE, PYL.EXE)
  • implemented workaround for fixup records lacking a target offset (although not entirely sure what those are actually about) (e.g. FATAL.EXE, PYL.EXE)
  • added support for call/jump stubs (i.e. call/jumps instructions with targets that only are determined at runtime via fixup records) (e.g. MK2.EXE)
  • added 'fixup takes precedence' logic for branch targets (i.e. fixups targets are considered more trustworthy and may override branch targets determined by objdump)
  • added feature to suggest possible object hints for code objects (based on the observation that data regions in code objects usually get access sizes assigned to them)
  • added preliminary support for a branch tracing disassembler (disabled by default, not ready for production yet)
  • applied many additional minor fixes/changes

Changelog for v2.0 release

  • comprehensive rewrite of the entire tool:
    • no longer monolithic, sources now split into separate modules
    • disassembler now centered around fixup records
    • overhauled and verified almost all of the source code
  • rebranded to 'wcdatool'

Changelog for v1.0 release

  • initial release
  • monolithic (everything in one single source file)
  • originally named 'wcdctool' (Watcom Decompilation Tool)
