  "message": "Reapply \"[Codegen] Use local binders for optimization flags in codegen (#24220)\" (#24333)\n\nPreviously, I made a workaround in\nhttps://github.com/iree-org/iree/commit/1b75890ac8093dd9b74b8110833bd2a46b3da7f0.\nThe main reason is that all the codegen pipeline tests were anchor on a\nsingle pass (e.g., `XXXLowerExecutableTargetPass`), which makes plumbing\nthrough options infeasible.\n\nAfter migrating to the real pipeline transformations, we are able to use\nthe option in whole pipeline tests; we can drop the old workaround from\niree-opt changes.\n\nThe revision introduces the option for each backend (default `O0`) and\nuse local binders to apply the optimization flags. It drops the\n`XXX::FromFlags::get()` uses from Codegen.\n\nThe additional change is updating the default value in `Passes.td` to\nnot apply optimization level. It was a workaround when we abused the\npass for optimization control. Now all the pipeline tests use textual\npass pipelines, so we no longer need the workaround.\n\nci-extra: linux_x64_clang_tsan\n\n---------\n\nSigned-off-by: hanhanW \u003chanhan0912@gmail.com\u003e",
