|

// Also note that all target features listed here must be purely additive: for target_feature 1.1 to
|
|
// be sound, we can never allow features like `+soft-float` (on x86) to be controlled on a

// per-function level, since we would then allow safe calls from functions with `+soft-float` to

// need to be treated very carefully to avoid introducing unsoundness! This often affects features

|
// that enable/disable hardfloat support (see https://github.com/rust-lang/rust/issues/116344 for an
|
