  "message": "Fix the wasm32-unknown-unknown target feature/cfg bug\n\nCurrently, `parse_cfg` calls `build_configuration`, which calls\n`default_configuration`, which calls\n`sess.target.singlethread(\u0026sess.internal_target_features)`. But\n`sess.internal_target_features` hasn\u0027t been set at this point and is\nempty!\n\nThis commit moves the setting of `sess.internal_target_features` before\nthe `parse_cfg` call to fix this ordering bug. This results in the\n`cfg(target_has_threads)` being correctly set on\n`wasm32-unknown-unknown` when `-Ctarget-feature\u003d+atomics` is specified.\n\nNote: I have plans to make this kind of ordering bug\ndifficult/impossible in a follow-up (e.g. #161432).\n",
