# vmassembler - VMProtect 2 Virtual Instruction Assembler
|
|
|
|
vmassembler is a small C++ project which uses [flex](https://en.wikipedia.org/wiki/Flex_(lexical_analyser_generator)) and [bison](https://www.gnu.org/software/bison/manual/) to parse `.vasm` files and assemble virtual instructions. The project inherits [vmprofiler](https://githacks.org/vmp2/vmprofiler) which is used to identify vm handler's, provide them with a name, immidate value size, and other meta data to aid in assembling virtual instructions.

### Contents
|
|
|
|
The repo contains the following notable folders and files:
|
|
|
|
* `dependencies/` - vmprofiler is the only dependency for this project...
|
|
* `src/` - source code for the vmassembler...
|
|
* `compiler.cpp` - responsible for encoding and encrypting virtual instructions...
|
|
* `parser.cpp` - a singleton class which is used in `parser.y`...
|
|
* `parser.y` - bison rules for parsing tokens. This contains only a handful of rules...
|
|
* `lexer.l` - lex rules for the vmassembler...
|
|
|
|
### Usage Requirements
|
|
|
|
In order to use the virtual instruction assembler you must first have a few values at hand. The required values are listed below:
|
|
|
|
* `vm_entry rva` - relative virtual address to a vm_entry...
|
|
* `image base` - image base value from optional headers... |
