Compilation Process

1

Source Code

The input code file (C, Rust, etc.) is first validated and preprocessed.

2

Optimization

The compiler optimizes control flow, data structures, and memory access patterns.

3

WebAssembly Generation

The final WebAssembly binary is generated with validation against the WASM spec.

.wasm
