Detailed Description

A variable node in the IR.

A variable is uniquely identified by its address.

Each variable is only bound once in the following nodes:

Member Data Documentation

◆ _type_child_slots

constexpr const uint32_t tvm::tir::VarNode::_type_child_slots = 1

staticconstexpr

◆ _type_key

constexpr const char* tvm::tir::VarNode::_type_key = "tir.Var"

staticconstexpr

◆ name_hint

String tvm::tir::VarNode::name_hint

The hint to the variable name.

Note: Each variable is uniquely identified by its address.

◆ type_annotation

Type tvm::tir::VarNode::type_annotation

type annotation of the variable.

It is an optional field that provides a refined type of the variable than dtype.

See also: tvm/ir/type.h for discussion of relations between runtime::DataType and Type.

The documentation for this class was generated from the following file:
