Message

Missing review: 1 & 9

Since v2:
- Extract decode_64bit_enabled()
- Remove unreachable 32-bit code

Since v1:
- Fixed '!is_double' check (rth)
- Rebased (removing tcg_temp_free calls)
- Simplified MULT[U].G (rth)
- Added R-b

Philippe Mathieu-Daudé (9):
  target/mips: Extract decode_64bit_enabled() helper
  target/mips: Simplify Loongson MULTU.G opcode
  target/mips: Re-introduce OPC_ADDUH_QB_DSP and OPC_MUL_PH_DSP
  target/mips: Convert Loongson DDIV.G opcodes to decodetree
  target/mips: Convert Loongson DIV.G opcodes to decodetree
  target/mips: Convert Loongson [D]DIVU.G opcodes to decodetree
  target/mips: Convert Loongson [D]MOD[U].G opcodes to decodetree
  target/mips: Convert Loongson [D]MULT[U].G opcodes to decodetree
  target/mips: Remove unreachable 32-bit code on 64-bit Loongson Ext
