tilelang.language.print module#

This module provides macros and utilities for debugging TileLang (tl) programs. It includes functionality to print variables, print values in buffers, and conditionally execute debug prints.

tilelang.language.print.print(obj: Any, msg: str = '') → PrimExpr#

A generic print function that handles both TIR buffers and primitive expressions.

  • If the input is a TIR buffer, it prints its values, but only on the first thread (tx=0, ty=0, tz=0).

  • If the input is a TIR primitive expression, it prints its value directly.

Parameters:

  • obj (Any) – The object to print. It can be either a tir.Buffer or tir.PrimExpr.

  • msg (str) – An optional message to include in the print statement.

Returns:

The TIR expression for the debug print operation.

Return type:

tir.PrimExpr

Raises:

ValueError – If the input object type is unsupported.
