Since v2:
- Fix translator_ld() calls
- Add support for 48-bit nanoMIPS opcodes
- Convert Load Immediate opcode
---

Prepare buildsys to decode micro/nanoMIPS opcodes using
the decodetree script.
Simplify gen_lsa/dsa() and convert micro/nanoMIPS LSA
opcode to decodetree.

Philippe Mathieu-Daudé (16):
  target/mips: Extract gen_base_index_addr() helper
  target/mips: Extract generic gen_lx() helper
  target/mips: Convert Octeon LX instructions to decodetree
  target/mips: Call translator_ld() in translate_insn() callees
  target/mips: Have gen_[d]lsa() callers add 1 to shift amount argument
  target/mips: Decode LSA shift amount using decodetree function
  target/mips: Introduce decode tree bindings for MIPS16e ASE
  target/mips: Introduce decode tree bindings for microMIPS ISA
  scripts/decodetree: Add support for 48-bit instructions
  target/mips: Introduce decode tree bindings for nanoMIPS ISA
  target/mips: Convert microMIPS LSA opcode to decodetree
  target/mips: Convert nanoMIPS LSA opcode to decodetree
  target/mips: Add gen_li() helper
  target/mips: Convert microMIPS LI opcode to decodetree
  target/mips: Convert MIPS16e LI opcodes to decodetree
  target/mips: Convert nanoMIPS LI opcodes to decodetree
