[PATCH] S/390: Extend jmp_buf data structure
- From: Andreas Krebbel <krebbel at linux dot vnet dot ibm dot com>
- To: libc-alpha at sourceware dot org
- Date: Mon, 9 Dec 2013 16:55:52 +0100
- Subject: [PATCH] S/390: Extend jmp_buf data structure
- Authentication-results: sourceware.org; auth=none
Hi,
the attached patch reserves space in the jmp_buf data structure for
future extensions.
Apart from the extra bytes also a flags field is added which might
help to ease such extensions in the future a bit.
Any comments?
Bye,
-Andreas-
