RFR[9u-dev]: 8150900: Implement diagnostic_pd

[Cheleswer Sahu]

Hi,

 

Please review the code changes for https://bugs.openjdk.java.net/browse/JDK-8150900.

 

Webrev Link: http://cr.openjdk.java.net/~csahu/8150900/webrev.00/

 

Enhancement Brief:  A new variant of flag "diagnostic_pd" is implemented. All flags which are diagnostic in nature and platform dependent can be placed

under this variant. These flags can be enable using  "-XX:+UnlockDiagnosticVMOptions".

At present I have placed 4 flags under "diagnostic_pd" 

1.        1. InitArrayShortSize

2.        2. ImplicitNullChecks

3.        3. InlineFrequencyCount

4.        4. PostLoopMultiversioning

 

 

Regards,

Cheleswer
