Struct CodeGen 

pub struct CodeGen { /* private fields */ }

Implementations

impl CodeGen

pub fn codegen_program( &mut self, program: &Program, type_map: HashMap<usize, Type>, statement_types: HashMap<(String, usize), Type>, ) -> Result<String, CodeGenError>

Generate LLVM IR for entire program

pub fn codegen_program_with_config( &mut self, program: &Program, type_map: HashMap<usize, Type>, statement_types: HashMap<(String, usize), Type>, config: &CompilerConfig, ) -> Result<String, CodeGenError>

Generate LLVM IR for entire program with custom configuration

This allows external projects to extend the compiler with additional builtins that will be declared and callable from Seq code.

pub fn codegen_program_with_ffi( &mut self, program: &Program, type_map: HashMap<usize, Type>, statement_types: HashMap<(String, usize), Type>, config: &CompilerConfig, ffi_bindings: &FfiBindings, ) -> Result<String, CodeGenError>

Generate LLVM IR for entire program with FFI support

This is the main entry point for compiling programs that use FFI.

impl CodeGen

pub fn can_specialize(&self, word: &WordDef) -> Option<SpecSignature>

Check if a word can be specialized and return its signature if so

pub fn codegen_specialized_word( &mut self, word: &WordDef, sig: &SpecSignature, ) -> Result<(), CodeGenError>

Generate a specialized version of a word.

This creates a register-based function that passes values directly in CPU registers instead of through the 40-byte %Value stack.

The generated function:

• Takes primitive arguments directly (i64 for Int/Bool, double for Float)
• Returns the result in a register (not via stack pointer)
• Uses musttail for recursive calls to guarantee TCO
• Handles control flow with phi nodes for value merging

Example output for fib ( Int -- Int ):

define i64 @seq_fib_i64(i64 %arg0) {
  ; ... register-based implementation
}

impl CodeGen

pub fn new() -> Self

pub fn new_pure_inline_test() -> Self

Create a CodeGen for pure inline testing. Bypasses the scheduler, returning top of stack as exit code. Only supports operations that are fully inlined (integers, arithmetic, stack ops).

pub fn set_aux_slot_counts(&mut self, counts: HashMap<String, usize>)

Set per-word aux stack slot counts from typechecker (Issue #350)

Trait Implementations

impl Default for CodeGen

fn default() -> Self

Returns the “default value” for a type.
