+ * JavaScript operation bytecodes.  If you need to allocate a bytecode, look
+ * for a name of the form JSOP_UNUSED* and claim it.  Otherwise, always add at
+ * the end of the table.
+ *
+ * Includers must define an OPDEF macro of the following form:
+ *
+ * #define OPDEF(op,val,name,image,length,nuses,ndefs,prec,format) ...
+ *
+ * Selected arguments can be expanded in initializers.  The op argument is
+ * expanded followed by comma in the JSOp enum (jsopcode.h), e.g.  The value
+ * field must be dense for now, because jsopcode.c uses an OPDEF() expansion
+ * inside the js_CodeSpec[] initializer.
+ *
+ * Field        Description
+ * op           Bytecode name, which is the JSOp enumerator name
+ * value        Bytecode value, which is the JSOp enumerator value
+ * name         C string containing name for disassembler
+ * image        C string containing "image" for pretty-printer, null if ugly
+ * length       Number of bytes including any immediate operands
+ * nuses        Number of stack slots consumed by bytecode, -1 if variadic
+ * ndefs        Number of stack slots produced by bytecode
+ * prec         Operator precedence, zero if not an operator
+ * format       Bytecode plus immediate operand encoding format
+ *
+ * Precedence   Operators               Opcodes
+ *  1           let (x = y) z, w        JSOP_LEAVEBLOCKEXPR

+ *
+ * The push-numeric-constant operators, JSOP_ZERO, JSOP_NUMBER, etc., have
+ * lower precedence than the member operators emitted for the . operator, to
+ * cause the decompiler to parenthesize the . left operand, e.g. (0).foo.
+ * Otherwise the . could be taken as a decimal point.  We use the same level
+ * 16 for function expressions too, to force parenthesization.
