# [SMDOC] LIR Opcodes
# =======================
# This file defines all LIR opcodes as well as LIR opcode class
# definitions. It is parsed by GenerateLIRFiles.py at build time to
# create LIROpsGenerated.h. Each opcode consists of a
# name and a set of attributes that are described below. Unless
# marked as required, attributes are optional.
#
# name [required]
# ====
# Opcode name.
# Possible values:
#   - opcode string: used as the name for LIR opcode.
#
# gen_boilerplate
# ===============
# Used to decide to generate LIR boilerplate.
#   - true (default): auto generate boilerplate for this LIR opcode
#   - false: do not generate boilerplate for this LIR opcode
#
# result_type
# ===========
# Specifies the result type that is produced by this LIR instruction.
# The result type can be any of the following: WordSized, BoxedValue,
# or Int64.
#   - attribute not specified (default): there is no result produced
#     by this LIR instruction
#   - result type: sets result type for this LIR instruction
#
# operands
# ========
# A list of operands to the LIR node. Each operand will be
# passed into and set in the instruction's constructor. A simple getter
# will also be auto generated for the operand. Each operand in the
# following list is defined by its name and an type.
# The type can be WordSized, BoxedValue, or Int64.
#
#   For example:
#     operands:
#       lhs: BoxedValue
#       rhs: WordSized
#
#   Will result in:
#     explicit LInstanceOfV(const LBoxAllocation& lhs, const LAllocation& rhs)
#         : LInstructionHelper(classOpcode) {
#       setBoxOperand(lhsIndex, lhs);
#       setOperand(rhsIndex, rhs);
#     }
#     const LAllocation* rhs() { return getOperand(0); }
#
#     static const size_t lhsIndex = 0;
#     static const size_t rhsIndex = BOX_PIECES;
#
#   - attribute not specified (default): no code generated
#   - list of operand names with their types: operand getters and setters
#     are generated and passed into the constructor
#
# arguments
# =========
# A list of non-LIR node arguments to the LIR op class constructor
# that are passed along with the operands. The arguments require
# both a name and a full type signature for each item in the list.
#
# For example:
#   offset: size_t
#   type: MIRType
#
# For each argument a private variable declaration will be autogenerated
# in the LIR op class, as well as simple accessor for that variable. The
# above arguments list will result in the following declarations and
# accessors:
#
#   size_t offset_;
#   MIRType type_;
#
#   size_t offset() const { return offset_; }
#   MIRType type() const { return type_; }
#
#   - attribute not specified (default): no code generated
#   - argument list: argument names and their full type signature
#
# num_temps
# ========
# Specifies the number of temporary virtual registers, LDefinitions, used by
# this LIR op.
#   - attribute not specified (default): number of temps is set to 0
#   - number of LDefinition temps: sets number of temps max 15
#
# call_instruction
# ================
# Used to define call instructions.
#   - attribute not specified (default): no code generated
#   - true: generates a call to setIsCall in the op's constructor
#
# mir_op
# ======
# If a LIR instruction corresponds one-to-one with a particular MIR
# instruction, this will generate a method that returns that MIR
# instruction.
#   - attribute not specified (default): no code generated
#   - true: generates a method to return MIR instruction
#   - mir string: returns this specified MIR instruction
