Richard Henderson a9814e3e08 target/riscv: Minimize the calls to decode_save_opc ... The set of instructions that require decode_save_opc for unwinding is really fairly small -- only insns that can raise ILLEGAL_INSN at runtime. This includes CSR, anything that uses a *new* fp rounding mode, and many privileged insns. Since unwind info is stored as the difference from the previous insn, storing a 0 for most insns minimizes the size of the unwind info. Booting a debian kernel image to the missing rootfs panic yields - gen code size 22226819/1026886656 + gen code size 21601907/1026886656 on 41k TranslationBlocks, a savings of 610kB or a bit less than 3%.
