# FIXME(#126180): This test doesn't actually run anywhere, because the only
# CI job that sets RUSTBUILD_FORCE_CLANG_BASED_TESTS runs very few tests.
# This test makes sure the embed bitcode in elf created with
# lto-embed-bitcode=optimized is valid llvm BC module.

//! Smoke test to make sure the embed bitcode in elf created with
//! `--plugin-opt=-lto-embed-bitcode=optimized` is valid llvm BC module.
//!
//! See <https://github.com/rust-lang/rust/issues/84395> where passing
//! `-lto-embed-bitcode=optimized` to lld when linking rust code via `linker-plugin-lto` doesn't
//! produce the expected result.
//!
//! See PR <https://github.com/rust-lang/rust/pull/98162> which initially introduced this test.
