Previously implemented:

  • AddSubMOp
  • BranchMOp

Newly implemented:

  • CompareMOp
  • ShiftRotateMOp (flags and shift amount overflow aren't implemented)
  • LogicalFlagsMOp

Not (yet) implemented:

  • LogicalMOp
  • ReadSpecialMOp (maybe this should not be in AluBranchMOp?)

Testing:

  • All rename_execute_retire tests pass with unit::alu_branch (test_rename_execute_retire_*_real)
  • Need more thorough testing of input/output values (probably a different PR)
