Benjamin Peterson 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 three additional commits since the last revision: - use space instead of :: - Merge branch 'master' into perfmap-stub-entries - 8383709: Linux perf map should record individual stubs StubRoutines blobs bundle many individually-named stubs into a single BufferBlob, so perf profiles previously attributed all samples inside those blobs to the enclosing blob name (e.g. "StubRoutines (compiler stubs)"). Walk the StubCodeDesc list and emit a line per descriptor, so perf can name the actual stub. ------------- Changes: - all: https://git.openjdk.org/jdk/pull/31007/files - new: https://git.openjdk.org/jdk/pull/31007/files/dd8cd113..0e095b9d Webrevs: - full: https://webrevs.openjdk.org/?repo=jdk&pr=31007&range=01 - incr: https://webrevs.openjdk.org/?repo=jdk&pr=31007&range=00-01 Stats: 42949 lines in 2061 files changed: 30064 ins; 6260 del; 6625 mod Patch: https://git.openjdk.org/jdk/pull/31007.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31007/head:pull/31007 PR: https://git.openjdk.org/jdk/pull/31007
