A simple script 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 designed for production use.
This script requires the following:
- Vlang compiler
- Clang
- Strip utility
$ vroom [path/to/file.v or path/to/dir] -o [output_executable]
$ vroom ./example.v -o example.elf
Using V 0.3.1 840370f as a baseline on x86_64.
| Tool/Compiler | Command | Binary size |
|---|---|---|
| Vroom (clang/gc) | vroom example -o example.elf | 44 kB |
| V tcc | v example -prod -gc none -o ex.elf | 92 kB |
| clang 12.0.1 | v example -prod -gc none -o s.c && clang -Oz s.c -o ex.elf | 157 kB |
| gcc 11.2.1 | v example -prod -gc none -o s.c && gcc -Os s.c -o ex.elf | 177 kB |
