I propose transforming: (InlineType .... (InlineType oop
where an `InlineType` references another `InlineType` node (maybe itself) through its `oop` input and with `Phi` or cast nodes in the subgraph in between into: (InlineType .... oop which requires cloning every cast or `Phi` nodes in the subgraph between the 2 `InlineType` nodes. That prevent sinfinite invocation of `PhiNode::push_inline_types_through` and cleans up the graph. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - more - more - cleanup - more - more - more - more - fix Changes: https://git.openjdk.org/valhalla/pull/2316/files Webrev: https://webrevs.openjdk.org/?repo=valhalla&pr=2316&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8302217 Stats: 444 lines in 5 files changed: 329 ins; 76 del; 39 mod Patch: https://git.openjdk.org/valhalla/pull/2316.diff Fetch: git fetch https://git.openjdk.org/valhalla.git pull/2316/head:pull/2316 PR: https://git.openjdk.org/valhalla/pull/2316
