2.2.0

Added

• ProcessorType.CORTEX_A72
• LinkableSymbolType enum for generalized representation of symbol types (essentially functions vs. data)

4.0.0

Changed

• Discard .altinstructions section when linking
• Use SUBALIGN(0) for .bss sections
• Force literal pool at end of function for AARCH64 using -mpc-relative-literal-loads

Added

• -fno-optimize-sibling-calls flag added to AVR toolchain.
• -fno-pic flag added to the GNU_10_Toolchain to omit GOTs in patches (FEMs) against binaries that aren't dynamically linked. (see #245)
• Add methods to parse relocation symbols from object files.
• Extend parsed symbol dictionary to include LinkableSymbolType.
• Extend AssembledObject and BOM types to include relocation and unresolved symbols.
• Add separate data sections support to LLVM toolchain, and add general flag for including subsections

Changed

• Switch to standard GCC-like frontend for LLVM, which supports C attribute(weak)

• Pass -mmcu value to the AVR preprocessor.
• Raise a more descriptive error on toolchain failure.

Fixed

• Toolchain preprocess() method now returns the path to the preprocessed file.

3.0.0

Added

• Add call to flush a resource to disk in the script whenever a user downloads a resource from the GUI. (#277)
• Generate dynamic, runnable script based on GUI actions and display the script in the GUI. (#265)
• Add -f/--file option to ofrak gui command to pre-load some files into OFRAK before opening the GUI, so they can be explored right away (#266)
• Add -i/--import option to the CLI to import and discover additional OFRAK Python packages when starting OFRAK. (#269)
• Add Identifier to tag ComplexBlocks as LinkableSymbols and Analyzer to copy attributes from a ComplexBlock to its LinkableSymbol. (#226)
• Add method to create new LinkableSymbols from symbols defined in a patch file. (#226)

Changed

• Remove need to create Resources to pass source code and headers to PatchFromSourceModifier and FunctionReplaceModifier (#249)
• Choose Analyzer components which output the entirety of a view, rather than piece by piece, which would choose the wrong Analyzer sometimes. (#264)
• Generate LinkableBinary stubs as strong symbols, so linker use them to override weak symbols in patch (#259)
• Limit stub file creation for linkable BOMs to only those required by a patch. (#226)

Fixed

• Fix bug where ComponentExternalTool would raise an error when checking whether a tool was installed returned a non-zero exit value (#289)
• Fix bug where jumping to a multiple of 0x10 in the GUI went to the previous line (#254)
• Fix installing on Windows, as well as small GUI style fixes for Windows (#261)
• Fixed Uf2File identifier so that it correctly tags UF2 files with Uf2File (#283)

Added

• Add GUI features
  • Keyboard shortcuts (#210)

Changed

• Updates to Flash components: (#195)
  • Flash components now support more than one occurrence of the same field type in FlashAttributes.
  • FlashOobResourceUnpacker continues to unpack even if blocks do not perfectly align at end of the FlashOobResource (this is useful for real-world flash dumps).
• Tweak how errors are raised when auto-running components, so the actual root cause is not buried (#219)
• Show mapped resource captions on hover in the hex view (#221)
• Change how resources are stored to making deleting (and thus packing) much faster (#201)
• Use non-blocking asyncio.create_subprocess_exec calls in components (#53)

Fixed

• Fix bug where initially loaded GUI resource has collapsed children (#209)
• Fix bug in GUI where "jump to offset" feature in hex view rounded up instead of down (#243)
