Hi, please consider. Inspired by [JDK-8313800](https://bugs.openjdk.org/browse/JDK-8313800). RISC-V also treats x8/fp as a callee-saved scratch register for some time, and it is freely used by C2-generated code. Therefore, any code in SA that uses getFP() in a compiled frame is very likely to come to grief.
