//! CSX64 is effectively a cross-platform, custom 64-bit processor emulator featuring its own execution engine, machine code, assembly language, and linker.
//! It was originally intended to be an educational tool to teach assembly programming in a safe, well-defined, platform-independent framework.
//! This crate contains only the CSX64 library code (no application/cli).
//!
//! # Example of Usage
//!
//! ```
//! # use csx64::*;
//! // an example program just to show the assemble/link/execute process
//! let prog_name = "demo.asm";
//! let prog = r"
//! global main
//!
//! segment text
//! main:
//! mov edi, 5
//! mov esi, 4
//! add edi, esi
//!
//! mov eax, edi
//! ret
//! ";
//!
//! // assemble the assembly program into an object file
//! let obj = match asm::assemble(prog_name, &mut prog.as_bytes(), Default::default()) {
//! Ok(obj) => obj,
//! Err(e) => panic!("{}", e), // assemble errors (above program has no errors)
//! };
//!
//! // get a copy of the C standard library object files (implemented in CSX64 assembly)
//! let mut objs = asm::stdlib();
//! objs.push((String::from(prog_name), obj)); // add our object file(s) to the end
//!
//! // link the object files into an executable - we want the starting point to be `main`
//! let exe = match asm::link(objs, Some(("start", "main"))) {
//! Ok(exe) => exe,
//! Err(e) => panic!("{}", e), // link errors (above program has no errors)
//! };
//!
//! // create an emulator, load up the executable, and execute
//! let mut emu = exec::Emulator::new();
//! emu.init(&exe, &Default::default());
//! let (_, state) = emu.execute_cycles(u64::MAX);
//! assert_eq!(state, exec::StopReason::Terminated(9)); // should terminate with result 9
//! ```
