Stefan Karlsson has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains two additional commits since the last revision: - Merge remote-tracking branch 'upstream/master' into 8329629_do_code_blob - 8329629: GC interfaces should work directly against nmethod instead of CodeBlob ------------- Changes: - all: https://git.openjdk.org/jdk/pull/18653/files - new: https://git.openjdk.org/jdk/pull/18653/files/e10683e2..1c2bdaea Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=18653&range=01 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=18653&range=00-01 Stats: 5545 lines in 115 files changed: 3743 ins; 1387 del; 415 mod Patch: https://git.openjdk.org/jdk/pull/18653.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18653/head:pull/18653 PR: https://git.openjdk.org/jdk/pull/18653
