  "message": "Reapply \"[Codegen][GPU] Add range information to GPU dispatch IDs\" (#19361) (#19372)\n\nThis reverts commit cb5be1dbd3560f692578c137eadbb413b41e44c7.\r\n\r\nCompaled to the previous revision, this one works around a correctness\r\nbug in dataflow analysis that\u0027s being fixed by removing the analysis\r\nafter SCF-\u003eCF.\r\n\r\n---\r\n\r\nFirst, this patch implements InferIntRangeInterface for\r\nhal.interface.workgroup.{size,id,count} using a local upper_bound\r\nattribute.\r\n\r\nThen, it adds a -iree-codegen-gpu-propagate-dispatch-size-bounds pass\r\nthat adds these upper_bounds identifiers to the interface.workgroup\r\noperations and to gpu.thread_id based on static information available\r\nlate in the codegen pipeline.\r\n\r\nThen, it uses -optimize-int-arithmetic to optimize indexing after\r\n-lower-affine, getting rid of a bunch of \"if the input\u0027s negative\" logic\r\nthat isn\u0027t actually needed in many of our kernels.\r\n\r\nIt also ensures that these upper_bound values propagate to LLVM.",
