machina
Manage and execute assembly at runtime.
Crossplatform?
Yap.
Why?
Emulators, JIT, dynarec, etc.
Example
extern crate machina;
extern crate sam; // just to keep it simple
use ;
use Memory;

extern crate machina;
#[macro_use]
extern crate sam; // just to keep it simple
use machina::cache::{Cache, STUB};
use machina::memory::Memory;
fn main() {
let asm = format!("mov rax, {}", STUB); // fill in a dummy address
let dummy = 64;
let address = &dummy as *const _; // address of dummy
let cache = Cache::new(true); // optimize?
let memory = Memory::new(1); // 1 page = 4096 bytes
cache.insert("mov_rax_x".to_string(), sam!(x64 => &asm)); // create the bytes at compile time via sam
memory.emit_bytes(cache.get_stub("mov_rax_x", address as u64)) // get "mov_rax_x" and fill in a dynamic address
let rax = memory.execute(); // returns rax
}
