rust/tests/run-make/ice-dep-cannot-find-dep/rmake.rs

// This test case creates a situation where the crate loader would run
// into an ICE (internal compiler error) when confronted with an invalid setup where it cannot
// find the dependency of a direct dependency.
//
// The test case makes sure that the compiler produces the expected
// error message but does not ICE immediately after.
//
// See https://github.com/rust-lang/rust/issues/83045

//@ only-x86_64
//@ only-linux
// Reason: This is a platform-independent issue, no need to waste time testing
// everywhere.

// NOTE: We use `bare_rustc` below so that the compiler can't find liba.rlib
//       If we used `rustc` the additional '-L rmake_out' option would allow rustc to
//       actually find the crate.
