tvm_tirx.ir.Var#

class tvm_tirx.ir.Var(name=None, ty=None, loc=UNKNOWN_LOC, *, name_hint=None)#

Bases: _CallableExprWithOp

A canonical local variable in the IR.

Parameters:
  • name (str, optional) – The display name. Variables with the same name remain distinct bindings.

  • ty (Optional[Type or str]) – The variable type, or MissingType when omitted. A string denotes a primitive dtype; "handle" denotes a pointer to void.

  • loc (Location, optional) – Location that points to the original source code.

  • name_hint (str, optional) – Keyword-only alternative to name; supply exactly one name spelling.

property name#
Var.expr_ty()#

Return this expression’s primitive result type.

Var.equal(other, loc=UNKNOWN_LOC)#
Parameters:

loc (Location)

Var.astype(dtype, loc=UNKNOWN_LOC)#
Parameters:

loc (Location)

Var.script(*, name=None, show_meta=False, int_dtype='int32', float_dtype='void', verbose_expr=False, indent_spaces=4, print_line_numbers=False, num_context_lines=-1, path_to_underline=None, path_to_annotate=None, obj_to_underline=None, obj_to_annotate=None, extra_config=None)#

Print TVM IR into TVMScript text format

Parameters:
  • name (Optional[str] = None) – The name of the object

  • show_meta (bool = False) – Whether to print the meta data of the object

  • int_dtype (str = "int32") – The default data type of integer

  • float_dtype (str = "void") – The default data type of float

  • verbose_expr (bool = False) – Whether to print the detailed definition of each variable in the expression

  • indent_spaces (int = 4) – The number of spaces for indentation

  • print_line_numbers (bool = False) – Whether to print line numbers

  • num_context_lines (int = -1) – The number of lines of context to print before and after the line to underline.

  • path_to_underline (Optional[List[AccessPath]] = None) – Object path to be underlined

  • path_to_annotate (Optional[Dict[AccessPath, str]] = None) – Object path to be annotated

  • obj_to_underline (Optional[List[tvm_ffi.Object]] = None) – Object to be underlined

  • obj_to_annotate (Optional[Dict[tvm_ffi.Object, str]] = None) – Object to be annotated

  • extra_config (Optional[dict] = None) – Dialect-specific configuration passed through to PrinterConfig.extra_config, including ir.prefix for the IR namespace alias (default "I"). Keys are conventionally namespaced as “<dialect>.<knob>”, e.g. {"tirx.prefix": "T"}.

Returns:

script (str) – The TVM Script of the given TVM IR

Return type:

str

Var.show(style=None, *, name=None, show_meta=False, int_dtype='int32', float_dtype='void', verbose_expr=False, indent_spaces=4, print_line_numbers=False, num_context_lines=-1, path_to_underline=None, path_to_annotate=None, obj_to_underline=None, obj_to_annotate=None, extra_config=None)#

Print highlighted TVMScript.

Parameters:

  • float_dtype (str = "void") – The default data type of float

  • verbose_expr (bool = False) – Whether to print the detailed definition of each variable in the expression

  • indent_spaces (int = 4) – The number of spaces for indentation

  • print_line_numbers (bool = False) – Whether to print line numbers

  • num_context_lines (int = -1) – The number of lines of context to print before and after the line to underline.

  • path_to_underline (Optional[List[AccessPath]] = None) – Object path to be underlined

  • path_to_annotate (Optional[Dict[AccessPath, str]] = None) – Object path to be annotated

  • obj_to_underline (Optional[List[tvm_ffi.Object]] = None) – Object to be underlined
