+# [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.
