Bastian Koppelmann	177726afb8	target/riscv: make ADD/SUB/OR/XOR/AND insn use arg lists ... manual decoding in gen_arith() is not necessary with decodetree. For now the function is called trans_arith as the original gen_arith still exists. The former will be renamed to gen_arith as soon as the old gen_arith can be removed. Backports commit f2ab1728675772cd475a33f4df3d2f68a22c188f from qemu	2019-03-19 05:17:54 -04:00
Bastian Koppelmann	cb7c94fbc4	target/riscv: Move gen_arith_imm() decoding into trans_* functions ... gen_arith_imm() does a lot of decoding manually, which was hard to read in case of the shift instructions and is not necessary anymore with decodetree.

Bastian Koppelmann	11e2b9c410	target/riscv: Convert RVXI arithmetic insns to decodetree ... we cannot remove the call to gen_arith() in decode_RV32_64G() since it is used to translate multiply instructions.

Bastian Koppelmann	5e5b3e9ea9	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 15:54:17 -04:00
