fn static_addr_of(
    &self,
    cv: Self::Value,
    align: Align,
    kind: Option<&str>
) -> Self::Value

fn codegen_static(&self, def_id: DefId, is_mutable: bool)

fn add_used_global(&self, global: Self::Value)

Mark the given global value as “used”, to prevent a backend from potentially removing a static variable that may otherwise appear unused.

Static variables in Rust can be annotated with the #[used] attribute to direct the rustc compiler to mark the variable as a “used global”.

#[used]
static FOO: u32 = 0;
