Use build-pass in ui tests where appropriate 2019-10-28 19:00:00 -05:00			`// build-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 16:51:35 -05:00			`#![allow(dead_code)]`
Add `#[allow(improper_ctypes)]` to slew of cases that need e.g. `repr(C)`. See also rust-lang/rust#53858. 2018-08-31 08:51:35 -05:00			`#![allow(improper_ctypes)]`

rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 15:13:15 -05:00			`// pretty-expanded FIXME #23616`

add rust_dbg_extern_identity_TwoDoubles to prevent check-fast failure 2013-04-14 00:15:46 -05:00			`struct TwoDoubles {`
remove the `float` type It is simply defined as `f64` across every platform right now. A use case hasn't been presented for a `float` type defined as the highest precision floating point type implemented in hardware on the platform. Performance-wise, using the smallest precision correct for the use case greatly saves on cache space and allows for fitting more numbers into SSE/AVX registers. If there was a use case, this could be implemented as simply a type alias or a struct thanks to `#[cfg(...)]`.
