Hi, This PR fixes various issues with `TypeAryPtr` and `TypeAryKlassPtr`. It starts with me trying to tighten the properties (`flat`, `null_free`, etc) of these classes, then fixing all the revealed issues until there are no crashes or wrong results left.
Please take a look and leave your reviews, thanks a lot. ------------- Commit messages: - Tighten the type system around array properties and fix related issues Changes: https://git.openjdk.org/valhalla/pull/1755/files Webrev: https://webrevs.openjdk.org/?repo=valhalla&pr=1755&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8372113 Stats: 448 lines in 18 files changed: 166 ins; 144 del; 138 mod Patch: https://git.openjdk.org/valhalla/pull/1755.diff Fetch: git fetch https://git.openjdk.org/valhalla.git pull/1755/head:pull/1755 PR: https://git.openjdk.org/valhalla/pull/1755
