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:

• Allocate
• For
• Let
• LetStmt

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.
