ADDITIONAL SYSTEM INFORMATION :
Ubuntu (Docker) on arm32 (Raspberry Pi 4)

A DESCRIPTION OF THE PROBLEM :
Background Info: I'm one of the JaCoCo developers and do OpenJDK CI builds on arm (Raspberry Pi 4) to test latest Java versions with JaCoCo.

Since changeset 57111:dff8053bdb74 (8234610: MaxVectorSize set wrongly when UseAVX=3 is specified after JDK-8221092 Reviewed-by: kvn, vlivanov) the build fails with the following error:


For target hotspot_variant-server_support_adlc__adlc_run_exec:
Ideal node missing: R8RegP
assert fails /workspace/src/hotspot/share/adlc/archDesc.cpp 484: Failed lookup of ideal node

Please find the fill build log here: https://gist.github.com/marchof/6104cd32701b3d4dce11b1af832a3cb0


REGRESSION : Last worked in version 14
