The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Fixed

• Fix some instructions missing their corresponding AccessType.

1.12.0 - 2024-07-21

Added

• RegistersTracker.getJrRegData.
  • Does what the old RegistersTracker.getJrInfo method does, but it returns an actual object instead of an nullable tuple and offers extra information.
• RegistersTracker.processBranch.
  • Allows tracking which registers has been used to decide branching.

Deprecated

• RegistersTracker.getJrInfo.
  • Use RegistersTracker.getJrRegData instead.

1.11.2 - 2024-07-16

Added

• Implement the rfe ("Restore From Exception") instruction.

Fixed

• Fix pmfhl, pmthl, vilwr and viswr missing the .fmt specifier.

1.11.1 - 2024-07-12

Added

• Instruction.isFunctionCall: Checks if the given instruciton is a function call.
  • If config.toolchainTweaks_treatJAsUnconditionalBranch is turned off then j instructions will be considered as function calls too. Useful for tail call optimizations.

Fixed

• Fix registers not being cleared after a j tail call, which was messing with the pointer pairing logic.

1.11.0 - 2024-05-22

Added

• New global configuration:
  • misc_expandJalr: If True then jalr instructions will be always emitted with two operands. Otherwise the rd register will be omitted if it is $ra and will be used explicitly if it isn't $ra. Defaults to False.

Fixed

• Fix crash in Rust bindings for to Rust 1.78.
  • This happens because slice.get_unchecked now performs OoB checks in debug builds, which is is triggered when trying to dereference unsized C arrays.
• Fix heap corruption in Rust bindings (#62)
  • The C API was returning string sizes without accounting for the null terminator, which produced issues on the Rust size which was not manually including it.

1.10.0 - 2024-04-22

Added

• Add PSP's ALLEGREX instruction set support.
• The global regNames.r4000AllegrexVfpuControlNamedRegisters option controls if named registers should be used for the VFPU control registers of the R4000 ALLEGREX.
• Utils.floatRepr_32From16 function.
  • Converts a half float to a single precision float.
  • Both the argument and the return value correspond to their hex representation instead of an actual float.

Changed

• Cleanups in tests code.

Fixed

• Fix typo on C++ bindings.
  • The registers getters of the R5900 instruction class was checking for the wrong operands.

1.9.5 - 2024-04-03

Changed

• Consider r5900's paddub as a possible move instruction.
• Internal rework to avoid allocating memory when calculating required buffer size for disassembly.
  • This is part of the RabbitizerInstruction_getSizeForBuffer function.
  • This change may help recent Windows specific issues.

1.9.4 - 2024-03-18

Changed

• Always use named registers for R5900's VU instructions.

1.9.3 - 2024-03-17

Fixed

Fixed

• Fix possible stack overflow if immOverride is larger than 255 bytes.

1.9.1 - 2024-02-18

Fixed

• Fix PyPI releases being broken due to a GHA update.

1.9.0 - 2024-02-18

Added

• Implement neg pseudo.

Changed

• Instruction.getProcessedImmediate now raises an exception if the instruction does not contain an immediate field.
• Instruction.getInstrIndexAsVram now raises an exception if the instruction does not contain an jump label field.
• Instruction.getBranchOffset now raises an exception if the instruction does not contain an branch label field.
• Extend Python's Instruction documentation.
  • Thanks to @Dragorn421 (PR #53)

Deprecated

• Instruction.isImplemented: Use Instruction.isValid instead.

1.8.3 - 2024-01-28

Fixed

• Fix Windows issue where jumptables where not properly identified.
  • Caused because of an issue on RegistersTracker.getJrInfo not using the correct type width for the return value on the Python binding.

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.
