Build

From the project root:

cmake -S . -B build
cmake --build build

Design direction

The long-term compiler architecture is planned around:

Vesper source
    ↓
Lexer / Parser
    ↓
AST
    ↓
Static Type System
    ↓
Vesper IR
    ↓
Vesper-specific optimizations
    ↓
LLVM IR
    ↓
LLVM
    ↓
Native code

Potential future areas include:

• native compilation
• LLVM backend
• improved numeric types
• ownership and memory-model features
• efficient multidimensional arrays
• SIMD
• parallel loops
• GPU computing
• C interoperability
• scientific-computing libraries

Features should only be marked as stable in the language documentation after they are implemented and tested.
