tilelang.errors
===============

.. py:module:: tilelang.errors

.. autoapi-nested-parse::

   Render source-location hints embedded in compiler error messages.

   C++ passes append a machine-readable location line to error messages when the
   relevant IR node carries a source span (see `src/span_utils.h`):


     --> /abs/path/to/kernel.py:21:1

   `enrich_error` rewrites the exception message in place (same exception type)
   to a clang/python-style snippet:

       tvm.error.InternalError: The layout for fragment C_local ...
         --> /abs/path/to/kernel.py:21:1
          |
       21 |     C_local = T.alloc_fragment((block_M, block_N), accum_dtype)
          |     ^

Module Contents
---------------

.. py:function:: enrich_error(exc)

   Append a rendered source snippet to a compiler error, when available.

   The exception object is returned unchanged (type and traceback preserved);
   only its message args are rewritten. Rendering failures fall back to the
   original message silently.
