// `no_builtins` is an attribute related to LLVM's optimizations. In order to ensure that it has an

// effect on link-time optimizations (LTO), it should be added to function declarations in a crate.

// This test uses the `llvm-filecheck` tool to determine that this attribute is successfully

|
|
// being added to these function declarations.
