      Description

        This implements JEP 422: Linux/RISC-V Port.

        This Linux/RISC-V Port supports RV64GV, shorthand for RV64IMAFDV ISA extensions, and covers the templateInterpreter, C1 and C2, excluding AOT/JVMCI. All existing GCs are available on riscv, including ZGC and ShenandoahGC. The VectorAPI and ForeignAPI features are not supported for now.

        This has been tested with jtreg tier{1,2,3,4} and jcstress on HiFive Unmatched board. Dacapo, SPECjbb2015 and SPECjvm2008 benchmark tests are also carried out regularly. So it should be good enough to run most Java programs.
