XCSL-AArch64 Change Log

Current Version: v0.27

0.27.0

  • Defined new FirmwareManager class to manage metadata for target hardware
    • Built some trivial test files for testing chips/firmware drivers
  • Framework started (but not used) for allowing Xita to cross-compile to a number of architectures
  • Coming Soon: A new grammar parser is needed to continue development on the Firmware framework
    • Firmware drivers and chip files need to have special syntactic parsers to separate userspace development

0.26.0

  • Rewrite/organized a lot of the project's documentation for open source collaboration
  • Started laying out the memory allocation system (not used in stable version)
    • Started organizing backend interactions between memory allocator and data types system
  • Designed new firmware system to restrict how memory can be accessed directly in Xita
    • Updated syntax highlighter to recognize *.chip files and driver-specific keywords
  • Reorganized code from private codebase into Xita-AArch64 (e.g. rpi3-boot.s, rpi3-linker.ld)

0.25.0

  • Started building and refining documentation
    • Added a README to expressions
    • Modified Makefile and other scripts for small name changes (e.g. XCS -> Xita)
  • Started combing through all source files to add comments, READMEs, etc.

0.24.0

  • Initial Version as Open Source
    • Officially changed name to XCS from Xita

0.23.0

  • Added high-level managers:
    • Assembly Manager
    • Operator Manager
      • Many operators are not fully operational
      • Overrides are temporarily broken
  • Reworked high-level managers
    • Types Manager
    • Functions Manager
      • BUG: Functions are required to be enclosed in ( )
  • NOTE: Many changes in 0.23.0 have broken core functionalities and introduced shift conflicts. The new changes are correct, so these bugs will need to be resolved before 0.24

0.22.0

  • Added l.log() commands to trace comiler backend logic flow
    • Operators
    • Functions
    • Parameters
    • Constants
  • Added initial lazy type-checking to Functions/Parameters
    • Buggy, but frequently works
  • Added initial eager type-checking to Constants

0.21.0

  • Added "CHANGES.md" to track changes between versions in text
  • Added initial framework/shell of XCSL's new ContextManager
  • Added global logger to XCSL Internal
    • Rewrote all Code to use l.log(), rather than printf()
