2025-10-28ZJIT: Print percentage of GuardType failureMax Bernstein
2025-10-28ZJIT: Count GuardType instructionsMax Bernstein
We can measure how many we can remove by adding type information to C functions, etc.

2025-10-28ZJIT: Stop computing offset on gen_push_opndsTakashi Kokubun
Once we add register spill, the C stack will have not only spilled basic block params but also spilled VRegs. We won't know how many stack slots are used for spilled VRegs until alloc_regs, so you can't compute an offset as of writing LIR.

2025-10-28ZJIT: Specialize Array#pop for no argument case (#14933)Aiden Fox Ivey
Fixes https://github.com/Shopify/ruby/issues/814 This change specializes the case of calling `Array#pop` on a non frozen array with no arguments. `Array#pop` exists in the non-inlined C function list in the ZJIT SFR performance burndown list. If in the future it is helpful, this patch could be extended to support the case where an argument is provided, but this initial work seeks to elide the ruby frame normally pushed in the case of `Array#pop` without an argument.

2025-10-28[ruby/json] Use Vector API in the Java ExtensionScott Myron
Overview This PR uses the [jdk.incubator.vector module](https://docs.oracle.com/en/java/javase/20/docs/api/jdk.incubator.vector/jdk/incubator/vector/package-summary.html) as mentioned in [issue #739](https://github.com/ruby/json/issues/739) to accelerate generating JSON with the same algorithm as the C extension. The PR as it exists right now, it will attempt to build the `json.ext.VectorizedEscapeScanner` class with a target release of `16`. This is the first version of Java with support for the `jdk.incubator.vector` module. The remaining code is built for Java 1.8. The code will attempt to load the `json.ext.VectorizedEscapeScanner` only if the `json.enableVectorizedEscapeScanner` system property is set to `true` (or `1`). I'm not entirely sure how this is packaged / included with JRuby so I'd love @byroot and @headius's (and others?) thought about how to potential package and/or structure the JARs. I did consider adding the `json.ext.VectorizedEscapeScanner` to a separate `generator-vectorized.jar` but I thought I'd solicit feedback before spending any more time on the build / package process. Benchmarks Machine M1 Macbook Air Note: I've had trouble modifying the `compare.rb` I was using for the C extension to work reliability with the Java extension. I'll probably spend more time trying to get it to work, but as of right now these are pretty raw benchmarks. Below are two sample runs of the real-world benchmarks. The benchmarks are much more variable then the C extension for some reason. I'm not sure if HotSpot is doing something slightly different per execution.

trace_getinstancevariable (#14969) We treat getinstancevariable differently from other opcodes: it does not look at the stack for its self operand, but instead looks at `cfp->self`. In some cases, we might see the `trace_` variant in the front-end, so make sure we treat that the same. Example repro: ``` def test @foo end 28.times do test end trace = TracePoint.trace(:call) do |tp| puts tp.method_id end trace.enable do 30.times do test end end ```
