Doxygen treats a number of different forms of comment blocks as comments that are intended to be included in documentation that it generates. Among these are comment lines that begin...

TR_EscapeAnalysis::fixupNode expects awrtbari Node to have a parent

1

As was reported in a [comment in issue #18074](https://github.com/eclipse-openj9/openj9/issues/18074#issuecomment-1708866308), code in [`TR_EscapeAnalysis::fixupNode`](https://github.com/eclipse-openj9/openj9/blob/999dfbcdc1edaee518235d900f94763dcf16491e/runtime/compiler/optimizer/EscapeAnalysis.cpp#L5613-L5633) that rewrites an `awrtbari` operation as an `astorei` check whether its parent is a check node or a...

Methods to access class depth and flags

2

There are several places in the JIT compiler that generate IL to access the `classDepthAndFlags` field of `j9class`. This introduces methods in `TR_J9VMBase` to do that, as has previously been...

Once upon a time, the JIT compiler's opcodes had the letter i as a prefix if the operation was indirect — `iiload`, `ibstore`, and so on. Those opcodes were renamed...

[0.48.0] Adjust bound for out-of-line call to StringUTF16.toBytes

1

Recognized Call Transformer generates IL that implements an inline version of `StringUTF16.toBytes` for values in the range [0,0x3fffffff], and that falls back to calling the Java implementation otherwise. In JDK...

java.lang.IllegalAccessException thrown for jdk.internal.misc.Unsafe.theUnsafe in Valhalla vt_standard testing

8

Many test failures are seen in recent PR sanity.functional testing with {x|z|a|p}linuxvalst (i.e., vt_standard) for pull requests #20112 and #20332. In most, if not all, cases `IllegalAccessExceptions` are thrown. I...

Prevent expanding sanity for Valhalla testing

5

The `sanity` test target is expanded to `sanity.functional,sanity.openjdk`. However, for Valhalla-specific testing, such as `xlinuxval`, the only test targets that are supported are `sanity.functional` and `extended.functional`. The `sanity.openjdk` is supported...
