Requires a Broadwell machine, but was able to reproduce with an emulator:

Thank you for fixing this, @vpaprotsk. Please also remove the problem listing of the compiler/arguments/TestCodeEntryAlignment.java:

jdk/test/hotspot/jtreg/ProblemList.txt

Line 82 in 84ffe87

compiler/arguments/TestCodeEntryAlignment.java 8372703 generic-x64

Meanwhile, I will run testing on our side and report back with the results.

Thanks @vpaprotsk for fixing this. Looks good to me (if tests are OK).

[dafedafe]

I was wondering if there are any reason for this value (apart that it is enough for the test to pass. I just noticed that it has been increased already in the past).

[vpaprotsk]

The assert was suggesting 119k (and change..) so I rounded slightly up. I was going to ask (i.e. @TobiHartmann ?) if thats enough..

(Similarly, I am concerned that I am contributing to a larger JVM footprint, with my changes.. but I suppose 11k is comparatively insignificant in the grand scheme of things...)

Thanks for the review!
