From 51a6b0c59a6170fc6a40221ef9b261b82856d315 Mon Sep 17 00:00:00 2001 From: Bodo Stroesser Date: Thu, 5 May 2005 16:15:38 -0700 Subject: [PATCH] uml: s390 preparation, sighandler interface abstraction s390 passes parameters in registers. So the only safe way to find out the address of signal context, error-address and error-type (trap_no), which are passed to signal handlers as parameters, is to declare these parameters. So I inserted an subarch-specific macro which holds the declaration of parameters for signal handlers.
