// Since #19941, rustc can accept specifications on its library search paths.
// This test runs Rust programs with varied library dependencies, expecting them
// to succeed or fail depending on the situation.
// The second part of the tests also checks that libraries with an incorrect hash
// fail to be used by the compiler.
// See https://github.com/rust-lang/rust/pull/19941
//@ ignore-wasm32
//@ ignore-wasm64
// Reason: a C compiler is required for build_native_static_lib
