RFR: 8349539: [leyden] Allow dumping nmethods that reference archived hidden klasses
by Aleksey Shipilev 11 Feb '25

11 Feb '25

WIP. I have yet to see if this has a good performance impact. Studying the bailout reasons for JavacBenchApp, I notices the majority of nmethod store bailouts are due to referencing the hidden klasses. Those checks seem to be from the initial commit. I wonder if we can actually skip hidden klass checks, now that we archive lots of those since invokedynamic AOT was implemented. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/33/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=33&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349539 Stats: 4 lines in 1 file changed: 2 ins; 0 del; 2 mod Patch: https://git.openjdk.org/leyden/pull/33.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/33/head:pull/33 PR: https://git.openjdk.org/leyden/pull/33

RFR: 8349748: [leyden] ciEnv::register_method should lock the correct queue lock
by Aleksey Shipilev 11 Feb '25

11 Feb '25

Mainline code locks `MethodCompileQueue_lock` in `ciEnv::register_method`. But with Leyden-s `UseGlobalCompileQueueLock = false`, we have separate locks, per compile queue. So it seems to stand to reason we should be locking those locks, not a global one. I have not been able to attribute this gap to any bug or performance issue, but I think we better fix this proactively. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/37/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=37&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349748 Stats: 1 line in 1 file changed: 0 ins; 0 del; 1 mod Patch: https://git.openjdk.org/leyden/pull/37.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/37/head:pull/37 PR: https://git.openjdk.org/leyden/pull/37

RFR: 8349722: [leyden] Option to block until preloading is complete
by Aleksey Shipilev 11 Feb '25

11 Feb '25

During one of the meetings, @iwanowww suggested there is a diagnostic option to block the execution until all preloaded code is finished loading. For the Java application, it would then look as if the entirety of preload code was loaded "instantaneously", which helps to estimate the performance floor for a given workload. I have found no such option in current Leyden prototype, though, so this RFE should implement one. This is indeed helpful, especially combined with #32, which allows to run with only C2. ------------- Commit messages: - Fix Changes: https://git.openjdk.org/leyden/pull/36/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=36&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349722 Stats: 7 lines in 2 files changed: 6 ins; 0 del; 1 mod Patch: https://git.openjdk.org/leyden/pull/36.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/36/head:pull/36 PR: https://git.openjdk.org/leyden/pull/36

RFR: 8349457: [leyden] Workaround Leyden problems with -XX:-TieredCompilation
by Aleksey Shipilev 11 Feb '25

11 Feb '25

Currently, supplying `-XX:-TieredCompilation` would break with Leyden workflows, because the archive-backed code cache heap would only be created if `SegmentedCodeCache` is enabled. With default compilation policy, this happens normally when tiered compilation is enabled, but not without it. There are other minor peculiarities that we need to handle, which are exposed with `runtime/cds` + `-XX:-TieredCompilation` runs. This prevents us from testing C2-only Leyden configs and studying compilation dynamics without tiered policy getting in the way. Additional testing: - [x] Ad-hoc Leyden experiments now work with `-XX:-TieredCompilation`: the C2-only code is being stored and loaded successfully from the CDS archive - [x] `runtime/cds` now passes with `-XX:-TieredCompilation` - [ ] `runtime/cds` still passes by default (i.e. with tiered compilation) ------------- Commit messages: - More fixes - Fix Changes: https://git.openjdk.org/leyden/pull/32/files Webrev: https://webrevs.openjdk.org/?repo=leyden&pr=32&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8349457 Stats: 38 lines in 3 files changed: 29 ins; 4 del; 5 mod Patch: https://git.openjdk.org/leyden/pull/32.diff Fetch: git fetch https://git.openjdk.org/leyden.git pull/32/head:pull/32 PR: https://git.openjdk.org/leyden/pull/32
