From 94c12cc7d196bab34aaa98d38521549fa1e5ef76 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 28 Sep 2006 16:56:43 +0200 Subject: [S390] Inline assembly cleanup. Major cleanup of all s390 inline assemblies. They now have a common coding style. Quite a few have been shortened, mainly by using register asm variables. Use of the EX_TABLE macro helps as well. The atomic ops, bit ops and locking inlines new use the Q-constraint if a newer gcc is used. That results in slightly better code. Thanks to Christian Borntraeger for proof reading the changes.
