// When compiling cdylibs or bins, only #[no_mangle] symbols are exported.
//
// Dylibs aren't supported, since they re-export all public symbols of all statically linked
// dependencies. In practice that means that all of the core crate is re-exported, which crashes the
// LLVM BPF target because of varargs, > 5 arguments, and all the other usual reasons. See
// https://github.com/rust-lang/rust/blob/0039d73/compiler/rustc_codegen_ssa/src/back/linker.rs#L1685
//
// staticlib and rlib don't link, they just store bitcode in .a/.rlib so they are not relevant.
