	# svd2rust uses proc-macro2, which decides at runtime whether to use
	# rustc's proc-macro based on whether calling it panics or not. i.e. it
	# uses std::panic::catch_unwind. This means that it aborts if panic=abort.
	# The latest version of proc-macro2 fixes this, provided rustc is >=
	# 1.57.0. So we can return to using panic=abort once we have updated to
	# 1.57.0 or later and updated proc-macro2.
