…an-DPC Remove unused `#[link_name = "m"]` attributes These were perhaps supposed to be `#[link(name = "m")]` but linking libm should be handled by the libc crate anyway. They should have triggered a compile error: rust-lang#47725
…acement, r=matthewjasper Validate built-in attribute placement Closes rust-lang#54584, closes rust-lang#47725, closes rust-lang#54044. I've changed silently ignoring some incorrectly placed attributes to errors. I'm not sure what the policy is since this can theoretically break code (should they be warnings instead? does it warrant a crater run?).
This fails to link with

#[link(name = "foobar")]
, the error is the expectedld: cannot find -lfoobar

libstd
using#[link_name = "m"] extern {...}
, so I wonder if those actually have any effect either.The text was updated successfully, but these errors were encountered:
