SourceMapping: undefined callee warnings in Inductor CI test #437

Description

@FindHao

The test-from-pip CI job emits this warning in the Run tests step:

2026-09-14 17:43:56,425 - tritonparse.SourceMapping - WARNING - Callsite #loc49 references undefined callee #loc1

CI log: step 10, line 2459

Observed context:

  • Test: tests.gpu.test_inductor_e2e.InductorTracingTest.test_launches_carry_compilation_metadata.
  • Nearby lines also report #loc47 and #loc51 referencing undefined callee #loc1, and #loc18 referencing undefined callee #loc6.
  • The test and the CI job both pass despite these warnings.
  • Commit: ef213a884f4bc1ff5e26204e8c2fadde73db00b4 on main.

Please investigate and address these source-mapping warnings.
