# riscv64 (RISC-V ELF)
Provide an implementation of the platform specific API as required in
[`api.h`](../api.h) according to the `RISC-V ELF ABI`.
## Notes: RISC-V ABI
- Integer/pointer arguments via `x10` - `x17`
- Integer/pointer return values via `x10` - `x11`
- Callee saved registers `x2`, `x8` - `x9`, `x18` - `x27`, `f8` - `f9`, `f18` - `f27`
