/* 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. */
