ofrak-patch-maker-v4.0.0

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)
• Treat weak symbols as "undefined" in BOM, so alternative, strong definitions can be searched
• 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.
