Mantis 7 — README
Deterministic Native Compiler + Runtime + Loader
===========================

Mantis 7 is a minimal, deterministic, zero‑copy compiler toolchain.
It takes Mantis source code (.mt), compiles it into portable bytecode
(.mtn), translates that bytecode into native machine code (x86‑64 or
ARM64), embeds a position‑independent string runtime, and executes it
directly from RWX memory.

The entire pipeline is designed to be:
- deterministic
- architecture‑aware
- zero‑copy
- allocation‑safe
- fully native (no interpreter fallback)
- minimal and transparent


## 1. Architecture Overview

Mantis 7 consists of four major components:

### 1. Compiler (compiler.py)
   - Parses .mt source files
   - Emits MTN1 bytecode (portable ISA)
   - Embeds a string‑blob table for literals

### 2. Backends (backend_x64.py / backend_arm64.py)
   - Translate MTN1 bytecode → native machine code
   - Map builtin calls (-2 = concat, -3 = to_string) to runtime offsets
   - Produce a pure native function with correct calling convention

### 3. String Runtime (string_runtime.py)
   - Fully position‑independent machine‑code blob
   - Contains:
       __mantis_strlen
       __mantis_memcpy
       __mantis_string_concat
       __mantis_format_i64
   - Provides a bump‑allocated heap for string operations
   - build() returns (blob, offsets)

### 4. Loader (loader.py)
   - Loads .mtn or .mtnb bundles
   - Extracts string blob for dispatcher
   - Builds runtime blob + offsets
   - Calls backend with offsets
   - Appends runtime to native code
   - Executes the result directly from RWX memory


## 2. File Types

.mt      — Mantis source file  
.mtn     — Single‑module bytecode file  
.mtnb    — Multi‑module bundle (MTNB format)  
          Contains modules + assets + offsets


## 3. Bytecode Format (MTN1)

Header:
```
    [magic "MTN1"]
    [fn_count u32]
    For each function:
        [code_len u32]
        code_len × instruction:
            [op u8][a i32][b i32][c i32]
    [string_blob_size u32]
    [string_blob raw bytes]
```
Instruction size: 13 bytes  
All integers: little‑endian  
All strings: UTF‑8, null‑terminated in runtime


## 4. Builtin Calls

The compiler emits negative function indices for builtins:
```
-1  → print(...)          (not yet mapped natively)
-2  → concat(a, b)        → __mantis_string_concat
-3  → to_string(i64)      → __mantis_format_i64
```
Backends resolve these using runtime offsets provided by build().


## 5. Native Execution Model

The loader:

1. Reads bytecode
2. Extracts string blob for dispatcher
3. Builds runtime blob + offset table
4. Calls backend:
      - emit_x64(bytecode, rt_offsets)
      - emit_arm64(bytecode, rt_offsets)
5. Appends runtime blob to native code
6. Allocates RWX memory
7. Copies native code into executable memory
8. Calls the entry function as:
       int64_t entry(void)


## 6. CLI Usage

The CLI entry point is:
```
    python cli.py {run|bench|build} {file.mt|project/}
```
Commands:

```
run
```
Compiles and immediately executes a single `.mt` file or a project.

Examples:
```
    python cli.py run hello.mt
    python cli.py run project/
```
Behavior:
- Compiles source → .mtn
- Loads .mtn via loader
- Executes native code
- Prints return value


```
bench
```
Runs a benchmark loop over the compiled program.

Examples:

    python cli.py bench fib.mt
    python cli.py bench project/

Behavior:
- Compiles once
- Executes N times (configurable)
- Prints timing statistics


```
build
```
Compiles a file or project into a standalone .mtn or .mtnb bundle.

Examples:

    python cli.py build hello.mt
    python cli.py build project/

Behavior:
- Produces .mtn for single file
- Produces .mtnb for multi‑module project
- Does NOT execute the result


## 7. Runtime Functions

```Python
__mantis_strlen(rdi)
#    Returns length of null‑terminated string.

__mantis_memcpy(rdi, rsi, rdx)
#    Copies rdx bytes from rsi → rdi.
#    Returns rdi.

__mantis_string_concat(a, b)
#    Allocates new buffer from bump heap.
#    Copies a, then b.
#    Null‑terminates.
#    Returns pointer.

__mantis_format_i64(value)
#    Converts signed 64‑bit integer to ASCII.
#    Writes digits in reverse, handles sign, null‑terminates.
#    Returns pointer.
```

## 8. Determinism Guarantees

- No dynamic dispatch
- No reflection
- No GC
- No OS‑dependent behavior
- No heap fragmentation (bump allocator only)
- All code generation is pure and reproducible
- All runtime functions are pure machine code with fixed offsets


## 9. Supported Architectures

x86‑64 (System V ABI)
ARM64 (AArch64, Linux / macOS / iOS)


10. Example

hello.mt:

    x = 41
    print("Result: {x + 1}")

CLI:

    python cli.py run hello.mt

Output:

    Result: 42
