[v2,0/6] target/mips: Convert nanoMIPS LSA opcode to decodetree

Message

Philippe Mathieu-Daudé Nov. 12, 2024, 5:20 p.m. UTC

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 (6):
  target/mips: Introduce decode tree bindings for microMIPS ISA
  target/mips: Introduce decode tree bindings for nanoMIPS ISA
  target/mips: Have gen_[d]lsa() callers add 1 to shift amount argument
  target/mips: Decode LSA shift amount using decodetree function
  target/mips: Convert microMIPS LSA opcode to decodetree
  target/mips: Convert nanoMIPS LSA opcode to decodetree
