Struct CompiledSpec 

pub struct CompiledSpec {
    pub name: String,
    pub src: Option<String>,
    pub bytes: Vec<u8>,
    pub ast: Arc<UOp>,
    pub var_names: Vec<String>,
    pub global_size: Option<[usize; 3]>,
    pub local_size: Option<[usize; 3]>,
    pub buf_count: usize,
}

Compilation result carrying source (JIT) or bytes (AOT).

Different backends need different information:

• LLVM JIT: needs source code to compile during runtime
• CUDA: needs PTX/CUBIN bytes to load
• Metal: needs metallib bytes to load

This design allows the RuntimeFactory to access whatever it needs without requiring separate code paths for JIT vs AOT backends.

Fields

name: String

Entry point function name

src: Option<String>

Source code (for JIT backends like LLVM) Set to Some(…) for LLVM JIT, None for AOT backends

bytes: Vec<u8>

Compiled bytes (for AOT backends like CUDA/Metal) Empty for LLVM JIT, populated for AOT backends

ast: Arc<UOp>

Original AST for cache key construction via hash consing

var_names: Vec<String>

Variable names in order for populating vars array at runtime. Includes thread_id at the end if threading is enabled.

global_size: Option<[usize; 3]>

Global work size for dispatch (GPU backends, CPU threading) For CPU threading: [thread_count, 1, 1]

local_size: Option<[usize; 3]>

Local work size for dispatch (GPU backends)

buf_count: usize

Number of buffer arguments (for CIF construction at compile time).
