[jira] [Updated] (GROOVY-7473) ineffient code generation

     [ https://issues.apache.org/jira/browse/GROOVY-7473?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jochen Theodorou updated GROOVY-7473:
-------------------------------------
    Component/s:     (was: bytecode)
                     (was: class generator)
                 Static compilation

>                 Key: GROOVY-7473
>                 URL: https://issues.apache.org/jira/browse/GROOVY-7473
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation
>    Affects Versions: 2.4.3
>            Reporter: Laurenz Tontsch
>              Labels: performance

> Groovy 2.4.3 generates not the most effient byte code of a simple statement like "in".
> e.g. The following statement:
> If object.stringProperty in ["State1", "State2", "State3"
> gets complied in:
> if (DefaultTypeTransformation.booleanUnbox((ScriptBytecodeAdapter.createList(new Object[] { "State1", "State2", "State3" }) == null ? 1 : 0) != 0 ? Boolean.valueOf(object.getStringProperty() == null) : Boolean.valueOf(DefaultGroovyMethods.isCase(ScriptBytecodeAdapter.createList(new Object[] { "State1", "State2 ", "State3" }), object. getStringProperty ()))))
> instead of this a more effient construct would be the usage of an static list
> e.g.
> static List<String> l1;
> static {
>         l1 = new LinkedList<String>();
>         l1.add("State1");
>         l1.add("State2");
>         l1.add("State3");
> }
> if (DefaultTypeTransformation.booleanUnbox((l1 == null ? 1 : 0) != 0 ? Boolean.valueOf(object.getStringProperty() == null) : Boolean.valueOf(DefaultGroovyMethods.isCase(l1, object. getStringProperty ()))))
