回复： please help understanding what's the relationship of hotspot compiler c1 and c2 ？

Hi,
Server VM will use C2, in this mode
which method processes 'volatile' operations like method do_StoreField in  src/share/vm/c1/c1_LIRGenerator.cpp?


Thank you !

Hi,
    When use tiered compilation (default enable in jdk8),tiered  VM can use C1 and C2 both [1].Client VM will use C1 and Server VM will use C2.


Thanks,
