11 operating system kernel. This document specifies the BPF instruction
134 instruction has one or more conformance groups of which it is a member.
152 BPF has two instruction encodings:
154 * the basic instruction encoding, which uses 64 bits to encode an instruction
155 * the wide instruction encoding, which appends a second 64 bits
156   after the basic instruction for a total of 128 bits.
158 Basic instruction encoding
161 A basic instruction is encoded as follows::
177     The format of these bits varies by instruction class
180     The instruction class (see `Instruction classes`_)
227 Wide instruction encoding
230 Some instructions are defined to use the wide instruction encoding,
232 the basic instruction format contain a pseudo instruction
270 The three least significant bits of the 'opcode' field store the instruction class:
298   the operation code, whose meaning varies by instruction class
312 **instruction class**
313   the instruction class (see `Instruction classes`_)
409 The ``MOVSX`` instruction does a move operation with sign extension.
429 The ``NEG`` instruction is only defined when the source bit is clear
438 The byte swap instructions use instruction classes of ``ALU`` and ``ALU64``
518 is in units of 64-bit instructions relative to the instruction following
519 the jump instruction.  Thus 'PC += 1' skips execution of the next
520 instruction if it's a basic instruction or results in undefined behavior
521 if the next instruction is a 128-bit wide instruction.
573 caller, and are referenced by offset from the instruction following the call
574 instruction, similar to ``JA``.  The offset is encoded in the 'imm' field of
575 the call instruction. An ``EXIT`` within the program-local function will
621   The instruction class (see `Instruction classes`_)
727 Instructions with the ``IMM`` 'mode' modifier use the wide instruction
729 basic instruction to hold an opcode subtype.
755 * code_addr(imm) gets the address of the instruction at a specified relative offset in number of (64-bit) instructions
771 index in the set associated with the BPF program containing the instruction.
785 carried over from classic BPF. These instructions used an instruction
