| /* The actual values of the various bytecode operations. |
| |
| Other independent implementations of the agent bytecode engine will |
| rely on the exact values of these enums, and may not be recompiled |
| when we change this table. The numeric values should remain fixed |
| whenever possible. Thus, we assign them values explicitly here (to |
| allow gaps to form safely), and the disassembly table in |
| agentexpr.h behaves like an opcode map. If you want to see them |
| grouped logically, see doc/agentexpr.texi. |
| |
| Each line is of the form: |
| |
| DEFOP (name, size, data_size, consumed, produced, opcode) |
| |
| NAME is the name of the operation. |
| SIZE is the number of argument bytes that the operation takes from |
| the bytecode stream. |
| DATA_SIZE is the size of data operated on, in bits, for operations |
| that care (ref and const). It is zero otherwise. |
| CONSUMED is the number of stack elements consumed. |
| PRODUCED is the number of stack elements produced. |
| OPCODE is the operation's encoding. */ |
