2021-10-07target/riscv: Add rev8 instruction, removing grev/greviPhilipp Tomsich
The 1.0.0 version of Zbb does not contain grev/grevi. Instead, a rev8 instruction (equivalent to the rev8 pseudo-instruction built on grevi from pre-0.93 draft-B) is available. This commit adds the new rev8 instruction and removes grev/grevi. Note that there is no W-form of this instruction (both a sign-extending and zero-extending 32-bit version can easily be synthesized by following rev8 with either a srai or srli instruction on RV64) and that the opcode encodings for rev8 in RV32 and RV64 are different.

2021-09-01target/riscv: Reorg csr instructionsRichard Henderson
Introduce csrr and csrw helpers, for read-only and write-only insns. Note that we do not properly implement this in riscv_csrrw, in that we cannot distinguish true read-only (rs1 == 0) from any other zero write_mask another source register -- this should still raise an exception for read-only registers. Only issue gen_io_start for CF_USE_ICOUNT. Use ctx->zero for csrrc. Use get_gpr and dest_gpr.

2021-05-11target/riscv: Consolidate RV32/64 32-bit instructionsAlistair Francis
This patch removes the insn32-64.decode decode file and consolidates the instructions into the general RISC-V insn32.decode decode tree. This means that all of the instructions are avaliable in both the 32-bit and 64-bit builds. This also means that we run a check to ensure we are running a 64-bit softmmu before we execute the 64-bit only instructions. This allows us to include the 32-bit instructions in the 64-bit build, while also ensuring that 32-bit only software can not execute the instructions.
