Why you used #if !defined() instead of #ifndef? We usually use #ifndef when checking one parameter. Thanks, Vladimir On 1/24/14 1:42 AM, Lindenmaier, Goetz wrote: Hi,
please review and test this small change: http://cr.openjdk.java.net/~goetz/webrevs/8032634-1-ifdef/ Please also review it for jdk8u. There are concerns that the OrderAccess operations we added to accesses of /thead/state for ppc64 harm performance on other platforms. Thus this change adds guards #ifdef PPC64 around it. Best regards, Goetz.
