Hi,
Thanks for taking care of RISC-V at the same time.
I think it would be cleaner if we do following for the RISC-V part:

Looks reasonable to me. Thanks for the update.
FYI: I have performed tier1-3 tests on linux-riscv64 board, result looks good.
Thanks for the review @coleenp and @RealFYang. |

Going to push as commit 5a259d8.
Your commit was automatically rebased without conflicts. |
The mirror needs to be stored in the frame for native calls also on AArch64 and RISC-V (as it is on other platforms).
See JDK-8303153 for more info.
Passes tier1-5 tests on AArch64. Done basic tests on RISC-V using QEmu.
