Function target_features_cfg

Source 
pub(crate) fn target_features_cfg(
    sess: &Session,
    allow_unstable: bool,
) -> Vec<Symbol>
Expand description

Used to generate cfg variables and apply features. Must express features in the way Rust understands them.

We do not have to worry about RUSTC_SPECIFIC_FEATURES here, those are handled outside codegen.
