Subject: [PATCH v3 01/16] x86/boot: do not create unwind tables
Date: Fri, 15 Apr 2016 14:33:01 +0200	[thread overview]
Message-ID: <1460723596-13261-2-git-send-email-daniel.kiper@oracle.com> (raw)
In-Reply-To: <1460723596-13261-1-git-send-email-daniel.kiper@oracle.com>

This way .eh_frame section is not included in *.lnk and *.bin files.
Hence, final e.g. reloc.bin file size is reduced from 408 bytes to
272 bytes and it contains only used code and data.

Suggested-by: Jan Beulich <jbeulich@suse.com>
