  "message": "[NVPTX] Use sink registers instead of temp registers where possible. (#134957)\n\nPTX 7.1 introduces the concept of a \"sink\" register, `_`, which is a\nregister to which writes are ignored.\n\nThis patch makes us use sink registers where possible, instead of using\nexplicit temp registers.\n\nThis results in cleaner assembly, and also works around a problem we\nencountered in some private workloads.\n\n(Unfortunately the tablegen is not particularly clean. But then again,\nit\u0027s tablegen...)",
