// An `.eh_frame` section in an object file is a symptom of an UnwindAction::Terminate
// being inserted, useful for determining whether or not unwinding is necessary.
// This is useless when panics would NEVER unwind due to -C panic=abort. This section should
// therefore never appear in the emit file of a -C panic=abort compilation, and this test
// checks that this is respected.
// See https://github.com/rust-lang/rust/pull/112403

//@ only-linux
// FIXME(Oneirical): the DW_CFA symbol appears on Windows-gnu, because uwtable
// is forced to true on Windows targets (see #128136).
