> The RISC-V port was originally developed at Huawei Technologies, then integrated into OpenJDK 19.
>
> The 17u version of the port has continued to be maintained in the openjdk/riscv-port-jdk17u repo later
> and has been tested for several months. There are few changes to shared HotSpot code (mostly the main
> one is C1 conditional move/branch support for RISC-V). As required by 17u maintainer, changes to shared
> code has been kept to a minimum. Only enabling shared changes are incorporated and these changes are
> properly guarded with macro RISCV. So this 17u port should not breaking existing code and, although it is
> a large patch, finally integrating it into 17u upstream should be low risk.
>
> Testing on linux-riscv64 platform:
> - [x] Bootcycle (release & fastdebug build)
> - [x] Tier1-4 tests (release build)
> - [x] Benchmark workloads (Dacapo, SPECJbb2015, SPECJVM2008, Renaissance. release build)
