Updated! Any reasons why?

I think this broke SDXL compilation with Sorry, CI results have been very noisy, particularly this morning. I also filed nod-ai/SHARK-TestSuite#286 for the poor failure mode in that workflow a few days ago (was hoping that would be noticed here during review and resolved, but I should have commented too). |

BTW please add PR descriptions in the future. I'm not sure from the logs and code if this was expected to change lowering paths and affect existing models, for example. |

Reverts #17847 This broke SDXL rocm pipeline tests on mi300, see #17847 (comment). The tests aren't showing error messages (`root:benchmark_sdxl_rocm.py:31 Command failed with error: b''`) so I can't easily tell what the issue is, nod-ai/SHARK-TestSuite#286 is filed to improve the situation there.
