// There used to be assert! checks in the compiler to error on encountering
// files starting or ending with < or > respectively, as a preventive measure
// against "fake" files like <anon>. However, this was not truly required,
// as rustc has other checks to verify the veracity of a file. This test includes
// some files with < and > in their names and prints out their output to stdout,
// expecting no errors.
// See https://github.com/rust-lang/rust/issues/73419

//@ ignore-cross-compile
// Reason: the compiled binary is executed
//@ ignore-windows
// Reason: Windows refuses files with < and > in their names
