Struct CContext 

pub struct CContext {
    pub hoisted_declarations: Vec<String>,
    /* private fields */
}

Context for C code generation, tracking variable names and SSA inlining.

Fields

hoisted_declarations: Vec<String>

Function-scope declarations for hoisted variables (emitted before kernel body).

Implementations

impl CContext

pub fn new( ref_counts: HashMap<u64, usize>, scope_escaping: HashSet<u64>, ) -> Self

pub fn get(&self, uop: &Arc<UOp>) -> &str

Get the C expression for a UOp. Panics if not registered.

pub fn register(&mut self, id: u64, expr: String)

Register a name/expression for a UOp ID.

pub fn should_inline(&self, id: u64) -> bool

Check if a value should be inlined (single-use, expression-safe).

pub fn next_name(&mut self, prefix: &str) -> String

Generate a unique variable name with given prefix.

pub fn indent(&self) -> String

Get current indentation string.

pub fn push_indent(&mut self)

Increase indentation depth.

pub fn pop_indent(&mut self)

Decrease indentation depth.

pub fn register_reduce_pending( &mut self, reduce_id: u64, acc_name: String, dtype: DType, )

Register a pending reduce final load.

pub fn take_pending_reduces(&mut self) -> HashMap<u64, (String, DType)>

Take all pending reduces.

pub fn emit_expr( &mut self, uop: &Arc<UOp>, expr: String, prefix: &str, kernel: &mut Vec<String>, ) -> String

Emit a C expression, either as an inline expression or a variable declaration. Returns the name/expression to reference this value.

Variables that escape their declaration scope are hoisted: declared at function scope and assigned at current depth. This prevents “use of undeclared identifier” errors when the linearizer places a shared node inside a loop but consumers exist outside the loop.
