From 7a02cfade80b2b6ed2562e74105bebfee90a87ec Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Tue, 24 Dec 2013 04:31:22 -0500 Subject: s390: implement sotruss support See commit 41b1792698a335d3a85381921a84a16e9635f36a for testcase. Note: while this works on s390x, the s390 code hangs when using -e. But it hangs regardless of this code (the hang seems to occur before the exit func is even called). I didn't look too closely at it as it seems to be an issue external to this file, so this code shouldn't make the situation any worse.
