-risc-v: 'c.unimp' instruction decoded as 'c.addi4spn fp, 0'
-
-QEMU 3.1 incorrectly decodes the "c.unimp" instruction (opcode 0x0000) as an "addi4spn fp, 0" when either of the two following bytes are non-zero. This is because the ctx->opcode value used when decoding the instruction is actually filled with a 32-bit load (to handle normal uncompressed instructions) but when a compressed instruction is found only the low 16 bits are valid. Other reserved/illegal bit patterns with the addi4spn opcode are also incorrectly decoded.
-
-I believe that the switch to decodetree on master happened to fix this issue, but hopefully it is helpful to have this recorded somewhere. I've included a simple one line patch if anyone wants to backport this.

-Thanks.  If you spin a full patch (ie, "git commit -s" and then "git show") I can drop it on riscv-qemu-3.1, our backports branch.  Otherwise hopefully we got the bug via the decodetree conversion.
-
-Since this bug isn't present in the decodetree version of the riscv decoder, we might as well just close this as fix-released; we won't be doing more point-releases of QEMU versions as old as 3.1.
