Member Data Documentation

annotations

ffi::Map<ffi::String, ffi::Any> tvm::tirx::ForNode::annotations

Additional annotations about the loop.

These annotations can be used as auxiliary hint to future transformations. An annotation should not change the control flow semantics of the loop and can be ignored in most passes.

body

Stmt tvm::tirx::ForNode::body

The body of the for loop.

extent

PrimExpr tvm::tirx::ForNode::extent

The extent of the iteration.

kind

ForKind tvm::tirx::ForNode::kind

The kind of the for loop.

loop_var

PrimVar tvm::tirx::ForNode::loop_var

The loop variable.

min

PrimExpr tvm::tirx::ForNode::min

The minimum value of iteration.

step

ffi::Optional<PrimExpr> tvm::tirx::ForNode::step

The loop step. It is one if not specified.

thread_binding

ffi::Optional<IterVar> tvm::tirx::ForNode::thread_binding

Only valid when kind == ForKind::kThreadBinding The context thread that this loop variable bounds to.
