// Running rustc with the -Z emit-stack-sizes
// flag enables diagnostics to seek stack overflows
// at compile time. This test compiles a rust file
// with this flag, then checks that the output object
// file contains the section "stack_sizes", where
// this diagnostics information should be located.
// See https://github.com/rust-lang/rust/pull/51946

//@ ignore-windows
//@ ignore-apple
// Reason: this feature only works when the output object format is ELF.
// This won't be the case on Windows/OSX - for example, OSX produces a Mach-O binary.
