1d506c26d9
This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* 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. */
