# [SMDOC] CacheIR Opcodes
# =======================
# This file defines all CacheIR opcodes and their arguments.
#
# Each op has the following attributes:
#
# name
# ====
# Opcode name. Convention is to use a name ending in *Result for ops that store
# to the IC's output register.
#
# shared
# ======
# If true, Baseline and Ion use the same CacheIRCompiler code for this op.
# If false, the op must be implemented in both BaselineCacheIRCompiler and
# IonCacheIRCompiler.
#
# transpile
# =========
# Whether this op can be transpiled to MIR by WarpCacheIRTranspiler.
#
# cost_estimate
# =========
# Score of an individual CacheIR Opcode's contribution to the overall score for
# each stub. This score is based off of the cost of the masm calls made by the op's
# implementation. The higher the score the more costly the op is.
#
# How to decide the cost estimate for a CacheIROp:
# 0 points - Generates no code
# 1 point - 1-5 simple masm ops, no callVM or callWithABI
# 2 points - 5-20 masm ops, no callVM or callWithABI
# 3 points - 20+ masm ops, no callVM or callWithABI
# 4 points - callWithABI
# 5 points - callVM
# 6 points - more than one callWithABI or callVM
#
# In the case of the op not being shared, default to counting the Baseline
# implementation.
#
# If the cost estimate is different based off of what branch of a conditional
# is taken, assign the score of the branch with the highest cost.
#
# Note:
# Currently, the scoring is tentative. It is in place to provide an
# estimate for the cost of each op. The scoring will be refined.
#
# custom_writer (optional)
# ========================
# If true, the generated CacheIRWriter method will be private and has a trailing
# '_'. This is useful for ops that need custom CacheIRWriter logic on top of the
# generated code.
#
# args
# ====
# List of arguments encoded in the bytecode stream. There are three argument
# kinds:
#
# - Id (ObjId, ValId, ...): refers to either an IC input or a value defined by
# a previous CacheIR instruction. This is encoded as integer in the bytecode
# stream.
#
# - Field (ObjectField, StringField, ...): specific value is stored in the stub
# data and the bytecode stream stores the offset of this field. This means the
# CacheIR is not specialized for particular values and code can be shared.
#
# - Immediate (BoolImm, Int32Imm, JSOpImm, ...): a value baked directly into
# the bytecode stream. This is useful for bits of state that need to be
# available to all CacheIR compilers/transpilers.
#
# If there's an argument named 'result', the generated CacheIRWriter method will
# return a new OperandId of this type.
