Looks good.

Is there difference between "C2 (tier 4)" and "C2 (tier4)" in tier[][] except space?

Thanks, Vladimir

Hi,

can I please have a review for the following test-only change: http://cr.openjdk.java.net/~simonis/webrevs/2018/8198915 https://bugs.openjdk.java.net/browse/JDK-8198915 When I wrote this test back in 2015, the WhiteBox API was not powerful enough (or I simply wasn't smart enough to use it :) so I used a lot of -XX options in order to run a method three times in a round where every execution was done at another compilation level (i.e. interpreted, C1 and C2). Unfortunately, the required redefinition of compiler counters and thresholds massively slows down Graal as can be seen in the bug report. I've therefore changed the test to use the Whitbox API to achieve the same test compilation without the need to redefine the global JIT compiler counters and thresholds. Thank you and best regards, Volker
