1.29.0

[1.29.0] - 2024-09-09

Added

• New ContextSymbol.functionOwnerForMigration attribute.
  • Allows to override to which function a given rodata symbol should be
    migrated to.
  • Specially useful for unreferenced symbols.
  • WARNING: It is undefined behavior if during rodata migration the listed
    function does not exists on the given text section. For example this symbol
    may get lost in limbo.

Fixed

• Fix data references to symbols with adends (that have user declared sizes)
  being symbolized instead of just using an addend to the symbol.
  • This bug seems like was only happening if the referenced symbol was in the
    same section as the one who was referencing it.

1.28.1

[1.28.1] - 2024-08-19

Changed

• Avoid emitting "global" visibility on labels.
• Avoid emitting a rom offset comment on bss symbols.
• Change on gpRelHack behavior:
  • Emit .externs with dummy size at the top of the function for all the
    %gp_rel-accessed symbols within the function.

Fixed

• Fix function symbols and labels not acknowledging their parent file.
  • Used mainly for debugging purposes.

1.28.0

[1.28.0] - 2024-08-09

Added

• New SectionText.gpRelHack setting.
  • Turning it on changes all instructions that use a %gp_rel reloc into macro
    instructions that do not specify the relocation explicitly nor reference the
    $gp register.
  • This may even change some instruction mnemonics, like replacing addiu into
    la.
  • This is required by old assemblers that do not support explicit %gp_rel
    relocations, but instead they infer the relocation to be used by checking
    if the symbol was defined in the assembly file and its size fits on the
    passed -G parameter.
  • WARNING: It is the user's responsability to provide those symbol definitions
    to the assembler, otherwise those instructions will be expanded into
    multiple instructions and produce a shifted build.
• elfObjDisasm's readelf:
  • Add MIPS_SCOMMON and MIPS_SUNDEFINED support in symtab.
  • Use the section name in the ndx column instead of a plain number for
    OBJECTs and FUNCs.

Changed

• Try to detect function pointers used on tail call optimizations and try to not
  confuse them with detected jumptables.
• rabbitizer 1.12.0 or above is required.

Fixed

• Fix rodata addresses referenced only by other rodata symbols on the same
  file not being properly symbolized.
• elfObjDisasm's readelf:
  • Fix name column not displaying the section's name.
  • Fix relocation sections not displaying anything on the name columns for
    relocations relative to a section instead of a symbol.

1.27.0

[1.27.0] - 2024-07-10

Added

• gcc_except_table support.
  • This section type is used by C++ to implement exceptions.
  • There's no automatic detection for this kind of symbol, so it must be
    manually specified by the user.
• Add two new SymbolSpecialType: gccexcepttable and gccexcepttablelabel.
  • gccexcepttable symbols will be prefixed with ehtbl_, while
    gccexcepttablelabel will have a $LEH_ prefix.
• A new kind of customizable label type for ehtable labels:
  • GlobalConfig.ASM_EHTBL_LABEL: Allows to change the macro label for this
    specific kind of label.
  • Defaults to ehlabel.

1.26.1

[1.26.1] - 2024-06-30

Changed

• singleFileDisasm
  • Produce an error if input file does not exist instead of silently doing
    nothing at all.

Fixed

• elfObjDisasm
  • Fix wrong capitalization on elf symbol visibility.
  • Fix symbol visibility not being used on some linked elfs.
• Fix some function pointers not being properly symbolized.
  • Those function pointers may get wrongly identified as jumptables because the
    jumptable pattern and the function pointer tail call pattern is similar.

1.26.0

[1.26.0] - 2024-05-21

Added

• Add visibility attribute to symbols.
  • Allows to specify custom visibility, like weak or local, to each symbol.
• Read symbol binding from elf files as visibility automatically.

1.25.1

[1.25.1] - 2024-05-03

Fixed

• Fix an edge case where strings may not get correctly disassembled when they
  contain the escape character (\\).
• Fix some overlay symbols not being properly created.

1.25.0

[1.25.0] - 2024-04-22

Added

• R4000 ALLEGREX instruction set compatibility
  • Used by the PlayStation Portable (PSP) CPU.
• rabbitizer 1.10.0 or above is required.

1.24.3

[1.24.3] - 2024-04-24

Changed

• Instruction analysis now follow all branches during look ahead analysis.
  • Look ahead analysis consists on taking branches and trying to follow the
    control flow without interrumping the main function analysis.
  • Old behavior trigered the look ahead analysis on a branch, but if a second
    branch was found during the look ahead analysis then it was ignored and not
    taken. This lead to some pointers not being properly paired if the codegen
    emitted the %hi and %lo separated by too many branches.
  • New behavior do follows branches during look ahead analysis, improving
    symbol pairing but making a bit slower the time needed for the overall
    analysis.
• rabbitizer 1.9.4 or above is required.
  • Should fix some issues under Windows.

1.24.2

[1.24.2] - 2024-03-26

Added

• GlobalConfig.SYMBOL_ALIGNMENT_REQUIRES_ALIGNED_SECTION.
  • Only emit symbol alignment directives if those are not larger than the
    alignment of the disassembled section.
