target/riscv: Initial introduction of the RISC-V target This ports over the RISC-V architecture from Qemu. This is currently a very barebones transition. No code hooking or any fancy stuff. Currently, you can feed it instructions and query the CPU state itself. This also allows choosing whether or not RISC-V 32-bit or RISC-V 64-bit is desirable through Unicorn's interface as well. Extremely basic examples of executing a single instruction have been added to the samples directory to help demonstrate how to use the basic functionality. 2019-03-08 18:06:28 +00:00			`obj-y += translate.o op_helper.o cpu_helper.o cpu.o csr.o fpu_helper.o pmp.o`

target/riscv: Activate decodetree and implemnt LUI & AUIPC for now only LUI & AUIPC are decoded and translated. If decodetree fails, we fall back to the old decoder. Backports commit 2a53cff418335ccb4719e9a94fde55f6ebcc895d from qemu 2019-03-18 19:41:19 +00:00

target/riscv: Convert RV64I load/store insns to decodetree this splits the 64-bit only instructions into its own decode file such that we generate the decoder for these instructions only for the RISC-V 64 bit target. Backports commit 7e45a682edc32ba90d6955215f062210531b835b from qemu 2019-03-18 20:02:12 +00:00			`decode32-y = $(SRC_PATH)/target/riscv/insn32.decode`

target/riscv: Split RVC32 and RVC64 insns into separate files This eliminates all functions in insn_trans/trans_rvc.inc.c, so the entire file can be removed.
