Unreleased

1.8.2 - 2024-01-28

Fixed

• Fix Windows issue on which symbols were not properly being paired.
  • This was caused because of a misuse of the type widths on the Python binding.

1.8.1 - 2023-12-25

Changed

• Minor cleanups on Rust code.
• Enabled -Werror=type-limits in the Makefile.

Fixed

• getBranchVramGeneric returns an unsigned type instead of a signed one.

1.8.0 - 2023-11-12

Added

• Add flag_r5900DisasmAsData member to the Instruction class.
  • This flag allows to fine-tune R5900 instruction set that are affected by the global gnuMode option.
    • Currently these instructions are: trunc.w.s, cvt.w.s, vclipw and vsqrt.
  • TrinaryValue.TRUE forces the instruction to be disassembled as data.
  • TrinaryValue.FALSE bypasses the global checks for disassembling a word as data. A word will still be disassembled as data if it can't be decoded.
  • TrinaryValue.NONE leaves this decision to the global settings.
• Add flag_r5900UseDollar member to the Instruction class.
  • TrinaryValue.TRUE forces the use of dollar signs ($) on R5900's VU instructions.
  • TrinaryValue.FALSE forces disassembling to not use of dollar signs ($) on R5900's VU instructions.
  • TrinaryValue.NONE leaves this decision to the global settings.

1.7.10 - 2023-09-24

Added

• Add Python binding for rabbitizer.__version_info__

Changed

Fixed

• Fix bug where the buffer size for a decoded instruction would be computed wrongly if the passed extraLJust parameter plus the global opcodeLJust option resulted in a negative value.

1.7.4 - 2023-06-13

Added

Fixed

• Fix getInstrIndexAsVram taking the upper 8 bits instead of 4 bits for the vram calculation

1.6.0 - 2023-04-17

Added

• Adds gnuMode to the configuration.

  • Enabled by default.
  • Turning this mode off makes the div $0, pseudo instruction to not be used

Changed

• Removed special treatment for R5900's trunc.w.s.
  • cvt.w.s and trunc.w.s will be decoded as-is when gnuMode is turned off.
