//! Primitive expressions: scalar arithmetic, comparisons and vector lanes.
//!
//! Laid out like `python/tvm_tirx/ir/prim/`: [`expr`] holds the scalar expressions,
//! [`vector_expr`] the vector ones and [`op`] the type-promoting operators. This module holds
//! [`expr_deep_equal`], from `prim/__init__.py`.

// An object registered under `prim` that no file has a block for yet is generated here, to be moved
// to the file of the Python module that defines it.
// tvm-ffi-stubgen(prefix): prim
// Names the hand-written wrappers use: the import section keeps them even when no generated block
// does.
// tvm-ffi-stubgen(import-object): tvm_ffi::Result
// tvm-ffi-stubgen(import-object): crate::ir::expr::Expr
// tvm-ffi-stubgen(import-object): crate::ir::expr::IntoExpr
