[PATCH bpf-next v1 0/3] bpf, riscv: Add compressed instructions to rv64 JIT

2020-07-20 Thread Luke Nelson
This patch series enables using compressed riscv (RVC) instructions in the rv64 BPF JIT. RVC is a standard riscv extension that adds a set of compressed, 2-byte instructions that can replace some regular 4-byte instructions for improved code density. This series first modifies the JIT to support
