I'm not objecting to this patch, which is fine as it goes, but I think that the real test for cross compiling isn't a different build and target platform, but a different build and target sysroot. You're often building for EL 9 on an EL 8 machine, and that really does need to be treated as cross compilation. ------------- PR Comment: https://git.openjdk.org/jdk/pull/16873#issuecomment-1831441045
