It was\r\nrequested that we could have non-SSE2 builds of the standard library available\r\nso they could continue to use vanilla releases and nightlies.\r\n\r\n[ff]: https://bugzilla.mozilla.org/show_bug.cgi?id=1253202"},"comment":{"url":"https://api.github.com/repos/rust-lang/rust/issues/comments/192164822","html_url":"https://github.com/rust-lang/rust/pull/32034#issuecomment-192164822","issue_url":"https://api.github.com/repos/rust-lang/rust/issues/32034","id":192164822,"user":{"login":"petevine","id":12054457,"avatar_url":"https://avatars.githubusercontent.com/u/12054457?v=3","gravatar_id":"","url":"https://api.github.com/users/petevine","html_url":"https://github.com/petevine","followers_url":"https://api.github.com/users/petevine/followers","following_url":"https://api.github.com/users/petevine/following{/other_user}","gists_url":"https://api.github.com/users/petevine/gists{/gist_id}","starred_url":"https://api.github.com/users/petevine/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/petevine/subscriptions","organizations_url":"https://api.github.com/users/petevine/orgs","repos_url":"https://api.github.com/users/petevine/repos","events_url":"https://api.github.com/users/petevine/events{/privacy}","received_events_url":"https://api.github.com/users/petevine/received_events","type":"User","site_admin":false},"created_at":"2016-03-04T07:41:45Z","updated_at":"2016-03-04T07:41:45Z","body":"On the off-chance someone actually tries to create binaries with this target (and not just `libstd`) I'd advise putting explicit `C(XX)FLAGS` in the `mk` file. \r\n\r\nI have no idea about msvc's default codegen on 32-bit but it's probably not i586."}}
