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.
