Can we simply change isMethodPointerConstant() in loadAddressConstantInSnippet() to chkMethodPointerConstant()? https://github.com/eclipse/omr/blob/efe8caf43537270e978f504215342bfba466f0b0/compiler/aarch64/codegen/OMRTreeEvaluator.cpp#L5355

That solution looks reasonable to me.

knn-k commented 1 year ago

I opened PR https://github.com/eclipse/omr/pull/7033 as the fix.

@knn-k : can you open a 0.40 PR in openj9-omr for this fix please?

knn-k commented 1 year ago

I opened https://github.com/eclipse-openj9/openj9-omr/pull/176 for v0.40.0.

knn-k commented 1 year ago

I think this issue can be closed.

0xdaryl commented 1 year ago

Fixed in 0.40.
