Jochen Theodorou updated GROOVY-11842:
--------------------------------------
Attachment: screenshot-1.png
> Invokedynamic first invocation should not have a line with IndyInterface
> ------------------------------------------------------------------------
>
> Key: GROOVY-11842
> URL: https://issues.apache.org/jira/browse/GROOVY-11842
> Project: Groovy
> Issue Type: Improvement
> Reporter: Jochen Theodorou
> Priority: Major
> Attachments: improved_indy.svg, screenshot-1.png
>
>
> As can be seen in the IndyInterfaceUsageTest there is a stack trace element
> showing IndyInterface. This is bad for inlining and general performance.
> !improved_indy.svg!
> of course a programm like
> {code:Java}
> int foo(){1}
> int a
> for (int i=0; i<MAX; i++) {
> a = foo()
> }
> {code}
> is not much of a test for anything. It was supposed to show better inlining,
> but unlike Groovy 3 all later Groovy version fail to unroll the loop and
> eliminate the assignment to a for later executions. The graph though shows
> that the branch performance is better than Groov 3 or 4. Not only in the long
> run, but also on start.
