Luau-disasmthis is my really fucking shit attempt at writing a luau disassembler.luau-disasm can both compile lua(u) scripts into luau bytecode, and disassemble luau bytecode from files.see here for the disassembly of a compiled version of Dex V2.disclaimersuh yeah expect bugs and stuffusageluau-disasm currently does not provide prebuilt binaries and will require building from source. for now, this project isn't for the average end user.Available options: -h, --help: Display this help message. -c, --compile: Enable compilation mode.

AzoteAzote is the faster and lightweight disassembler for AArch64.TODOAdd AArch32 support.Add x86 support.Possibly SVE extension support ?FeaturesExtremely fast and tinny in size.Supports all instructions of ARMv8.3 including (SIMD, NEON, FP16,...).No dependencies on platform specific APIs (it should run on all platforms).Supports switching to aliases instructions.Supports FPC and Delphi.For each decoded instruction, it provides all the necessary info for a good analysis.Built with unique feature "Patches" which explains why it's fast and lightweight.Fast & lightweightADTAzote decodes instructions based on highly optimized arbitrary decision tree (ADT) which was generated using the same algorithm uses by GNU Binutils. However, I improved it to fits Azote needs as follow:Uses single instruction for testing (only test) rather than three instruction (mov,shift and test). As a result, the generated code remains small and faster.When the last node is not sealed, the tree shots the instruction that has the highest number of set bits of its mask. As a result, the disasm guarantees that it will never confuse between two similar instruction. Also, when disassembling, it will never waste time to do semantic checks that allow to distinguish between those two instructions.The same rules above applies to aliases instructions.PatchesWhile current available solutions push instructions variants into their tables and decode operands based on a search of pattern match between the instruction and the variant. Azote does not do that! Azote decodes operands against the standard decoder and applies patches to fix the result (patches were already generated on the fly). As a result:Azote's table remains small because

RopperYou can use ropper to display information about binary files in different file formatsand you can search for gadgets to build rop chains for different architectures (x86/X86_64, ARM/ARM64, MIPS/MIPS64, PowerPC/PowerPC64, SPARC64).For disassembly ropper uses the awesome Capstone Framework.InstallInstall Capstone with PyPi:$ sudo pip install capstoneInstall filebytes with PyPi:$ sudo pip install filebytesOptional (not needed to run ropper just to look for gadgets):Install Keystone:$ sudo pip install keystone-engineInstall and execute Ropper$ python setup.py install$ ropperYou can also install Ropper with pipIf you want, you can use Ropper without installationIf you don't want to install filebytes, filebytes is a submodule of the ropper repository.
