The result mismatches with eager when input has `inf`, since `inf * 0` will result to `nan` based on [IEEE_754](https://en.wikipedia.org/wiki/IEEE_754). Change the code gen to `f\"std::max({x}, decltype({x})(0))\"` to align with eager implementation as in https://github.com/pytorch/pytorch/blob/1deb75b5846c6bb39773a4f210379f983250d802/aten/src/ATen/native/cpu/TensorCompareKernel.cpp#L392\n\n**TestPlan**\n```\npython -u -m pytest test_cpu_repro.py -k test_relu_with_inf_value\n```\n\nPull Request resolved: https://github.com/pytorch/pytorch/pull/117622\nApproved by: https://github.com/jgong5, https://github.com/lezcano","shortMessageHtmlLink":"fix cpp backend relu codegen with inf input (<a class=\"issue-link js-issue-link\" data-error-text=\"Failed to load title\" data-id=\"2085758685\" data-permission-text=\"Title is private\" data-url=\"https://github.com/pytorch/pytorch/issues/117622\" data-hovercard-type=\"pull_request\" data-hovercard-url=\"/pytorch/pytorch/pull/117622/hovercard\" href=\"https://github.com/pytorch/pytorch/pull/117622\">pytorch#117622</a>)"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAAD5L-WSwA","startCursor":null,"endCursor":null}},"title":"Activity · michaelhan1208/ai-pytorch"}
