Dalvik

This repository contains several modules that implement different functionality

dalvikdex

This module is used for parsing data from .dex files

• Adler32 verification
• SHA-1 verification
• String parsing
• Type ID parsing
• Prototype ID parsing
• Method ID parsing
• Field ID parsing
• Method parsing
• Field parsing

dalvikinst

This module is used for decoding Dalvik bytecode

• const-string
• invoke-virtual
• return-void
• return

Note: dalvikinst might support other instructions, but if they are not on this list that means they have not been tested yet

dalvikvm

This module is used for interpreting decoded Dalvik bytecode

• Bytecode interpretation
• Standard library

Performance notes

• VecReader and its convenience functions(read_u16, read_u32, etc) probably add a lot of overhead, but its probably fine as long as its only used when parsing something
• opt-level in release profile probably needs to be changed to 2(or maybe even 3) for better performance

General code notes

• Result<(), Box<dyn Error>> <- That doesnt look like a good idea
• The entirety of dalvikinst is horrible
• I have no idea how to cleanly make instruction invocation in DalvikVm(maybe clean up dalvikinst and put something like an execute function in each of the instruction implementations in dalvikinst?)
