BishengJDK 11 now brings the template interpreter and backends of C1/C2 compiler to the RISC-V world. We supports RV64G (G used to be represent the IMAFD base and extensions of RISC-V ISA) with BV (bit-manipulation and vector extensions) on the way, and the compressed instructions are out of plan.
Please refer to the building suggestions.
BishengJDK follows GPLv2 with Classpath Exception,see License。
Features:
We almost cover all components of jdk11, except AOT/Graal and Shenandoah GC. The Shenandoah GC will comming soon in the near future, and AOT and Graal is depending. Note that the OpenJDK community has disabled the features in Oracle builds in JDK16.
B/V extensions
Intrinsics
Considerations:
Frame layout
Cross-modifying code
Comparing to other architecutures, more efforts were paid in the code genaration for addressing the short offset of branch instructions, the no-flag-register architecture, the simplest addressing mode and so on.
