I propose to check the support level in configure and report it to the user. It is trivial to check the platform with a case block. The compiler name can be detect by builtin macro names like ``__clang__``.\r\n\r\nA message at build time makes support tier more obvious to the user. It might even nudge some vendors to contribute fixes and build bots.\r\n\r\nExample:\r\n\r\n```\r\nchecking for PEP 11 support tier... x86_64-pc-linux-gnu/gcc has tier 1 (supported)\r\n```\r\n\r\n```\r\nchecking for PEP 11 support tier... wasm32-unknown-emscripten/clang is not supported\r\n...\r\nconfigure: creating Modules/Setup.local\r\nconfigure: creating Makefile\r\nconfigure:\r\n\r\nIf you want a release build with all stable optimizations active (PGO, etc),\r\nplease run ./configure --enable-optimizations\r\n\r\nconfigure:\r\n\r\nPlatform \"wasm32-unknown-emscripten\" with compiler \"clang\" is not supported by\r\nCPython core team, see https://peps.python.org/pep-0011/ for more information.\r\n```","author":{"url":"https://github.com/tiran","@type":"Person","name":"tiran"},"datePublished":"2022-06-04T10:52:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/93491/cpython/issues/93491"}
