[9] RFR (S): 8150349: Reduce the execution time of the hotspot_compiler_3 group

[Vladimir Kozlov]

I am fine with removal of adler32 and bmi testing from JPRT runs because we don't have a plan to touch them.
But code related to CRC32, CRC32c and string may be touched soon for some platforms.
What if we created hotspot_compiler_4 group for them? How much time it would take to run it on slow platforms?

Thanks,
Vladimir
