A program to build the smallest Vlang executable possible. Please note that this may break executables or make cryptic errors. Also, this is a short PoC about executable optimization for V and it was not recommend for production use.
This program requires the following:
- Vlang compiler
- C Compiler (one of Tcc, Gcc or Clang)
- Strip utility (Optional)
- UPX utility (Optional)
Use GUI
or command line
$ vroom [path/to/file.v or path/to/dir] -o [output_executable]
$ vroom ./example.v -o example.elf
Using V 0.3.3 791ef4b as a baseline on x86_64.
