Subject: [RFC PATCH u-boot 03/12] linker_lists: declare entries and lists externally visible
Date: Wed,  3 Mar 2021 05:12:02 +0100	[thread overview]
Message-ID: <20210303041211.26945-4-marek.behun@nic.cz> (raw)
In-Reply-To: <20210303041211.26945-1-marek.behun@nic.cz>

Use the `__visible` macro to declare entires and lists declared by
ll_entry_declare() and ll_entry_declare_list() externally visible, so
that when building with LTO the compiler does not optimize this data
away.
