RFR 8190887 Stub code marking missing from some x86 generated stub routines

[Paul Sandoz]

Hi,

Please review this patch to ensure all generated stub code is printed when -XX:+PrintStubCode is set. Some generators were not participating and their code was not printed out.

I eyeballed the x86_64 output. I dunno if there are some explicit sanity tests.

Is it worth updating the generators for x86_32? (more awkward to eyeball).

Thanks,
Paul.
