We will first give an overview of the current state of the QEMU RISC-V implementation. Thereafter, we will present the DecodeTree tool, which will be available with the next QEMU release. DecodeTree is a code generator included in QEMU that can generate the program logic for extracting and decoding opcodes and operands from a formal instruction list of the target architecture. This enables the structured implementation of just-in-time compilations to guarantee that the QEMU implementation meets the ISA specification. As such, we completely replaced the existing RISC-V RV32GC and RV64GC implementations by DecodeTree generations in the next official QEMU release, which is expected in spring 2019. We will demonstrate the DecodeTree applications by the example of RISC-V ISA subset configurations.","lang":"eng"}]}
