It's checking if `OPENJDK_TARGET_CPU` is aarch64, but that's the global target for the whole configuration. It should be checking if the current compiler target is aarch64. Before calling `FLAGS_SETUP_CFLAGS_CPU_DEP`, variables for this are setup. In this case you should be using `FLAGS_CPU` and `FLAGS_OS` instead of `OPENJDK_TARGET_CPU` and `OPENJDK_TARGET_OS`. ------------- PR Comment: https://git.openjdk.org/jdk/pull/27073#issuecomment-3275110912
