Mads Ager	690b8e0ac9	JVM_IR: Optimize null checks. ... Introduce lowering to remove null checks for primitive type expressions and replace them with true/false. Side-effects are preserved. Generate ifnull/ifnonnull instructions for null checks instead of materializing a null literal for an equality check.	2019-01-19 09:43:43 +01:00
Alexander Udalov	5b58eb8491	Remove LANGUAGE_VERSION from non-coroutine codegen tests ... Most of these tests used this directive as a way to opt in to a new language feature, and most of those features are already stable for a long time, so no opt-in is needed. Some other tests used the directive to opt out from a language feature, replace those by the `LANGUAGE` directive. One test used the directive to test behavior that actually depended on the API version; use `API_VERSION` directive there instead.	2018-12-20 12:53:23 +01:00
Dmitry Petrov	78b69cad77	Support lateinit local vars in redundant null check elimination ... Lateinit local vars are guaranteed to be non-null after store. So we mark such stores as storing non-null value (could be useful for some other constructs, too), and optimize null checks accordingly.	2017-08-31 11:28:08 +03:00
