8242210: [lworld] TestCallingConvention::test36 spuriously fails #13

wants to merge 1 commit into from

@TobiHartmann TobiHartmann commented Apr 7, 2020


  • G1 pre- and post-barriers used when (un-)packing arguments for the calling convention can call into the runtime which screws up argument registers. Save all registers until JDK-8232094 is fixed in mainline (it's the slow path anyway).
  • SignatureStream::as_value_klass triggers a SystemDictionary lookup which acquires the ProtectionDomainSet_lock. When used from fieldDescriptor::print_on_for when some debug printing flags are enabled, this conflicts with the tty_lock. We should simply use get_value_field_klass instead. Also, we should handle null as a vale for non-flattened fields.
  • TraceDeoptimization needs to handle re-allocation of the inline type return value.

I've also added a new StressCC option to the ValueTypeTest suite to randomly restrict some compilation to C1 and thereby stress test the calling convention.
