tvm_tirx.tirx.transform.AnnotateEntryFunc

tvm_tirx.tirx.transform.AnnotateEntryFunc()

Infer and mark an unambiguous TIRx entry function.

Sets tirx.is_entry_func when the module contains only one function and it is TIRx, or when exactly one function is externally exposed and it is a TIRx function.

Returns:

fpass (tvm_tirx.ir.transform.Pass) – The result pass

Examples

import tvm_tirx as tvm
from tvm_tirx.script import ir as I, tirx as T
from tvm_tirx.tirx import transform as tr

@I.ir_module
class Before:
    @T.function(private=True)
    def main():
        pass

@I.ir_module
class Expected:
    @T.function(private=True)
    def main():
        T.func_attr({"tirx.is_entry_func": True})

def run_pass():
    return tr.AnnotateEntryFunc()(Before)

tvm.ir.assert_structural_equal(run_pass(), Expected)
