Isa

Ribbon Bytecode Instruction Set Architecture

Overview
Instructions

This is the canonical instruction set architecture (ISA) definition for the Ribbon virtual machine bytecode.

Overview

Basic layout

The ISA is divided into Categories;

Categories are further divided into Mnemonic bases;

Mnemonics then contain tables describing each concrete instruction variation.

Example

callc and call_v are both under the call mnemonic, within the Control Flow category.

JIT-only Instructions

Instructions with a jit tag above their name are only available when Rvm is compiled with the jit option.

Encoding

We display the encoding of each instruction as segmented bytes. The Ribbon bytecode is always in little endian order, and we display these bytes as they are ordered in memory.

The opcode is shown first, as a two byte hexadecimal number.

Padding bytes are shown as __.

In addition to standard hex characters and underscores, we utilize operand encoding symbology, such as Rx, indicating the first register operand to use. Symbolic operand character sequences will begin with a capital letter, and will be the appropriate width for the operand’s bytes if they were shown in hex form.

Nybbles displayed with . continue the value to the left of them.

Some instructions take up multiple words. We display word boundaries as line breaks within the tables’ Encoding columns, with subsequent instruction address representations arranged lower within these lines. Where the number of words used is dynamic, a trailing line containing ... will be shown.

Example

An instruction with a u16 immediate operand will use the notation I. .., because it is 2 bytes.

Similarly, Register operands are simply R. or Rx, Ry, etc because they are 1-byte identifiers.

As a concrete example, store64c, an instruction which stores a 64-bit immediate value (encoded as Iy) to memory at the address in a designated register (encoded as R), offset by another 32-bit immediate value (encoded as Ix), has an encoding column entry like this:

Encoding
`2d` `00` `R.` `Ix` `..` `..` `..` `__` `Iy` `..` `..` `..` `..` `..` `..` `..`

Immediate Operands

Immediate operands are formatted with I; immediate in this context means that the value is literally encoded into the byte stream, rather than encoding a reference to the value. We allow up to 64-bit immediates for all operations that are binary or greater in arity; in all cases the bit size of the immediate operand and the bit size of the operation must match. (I.e. there is no ‘add 8 bit imm to 32 bit reg’ instruction.)

Where instructions utilizing immediate operands are commutative, the version of the instruction taking a constant will be suffixed with c.

For instructions that do not commute, the two constant versions will be suffixed with a and b respectively, indicating whether the constant is used on the left or right side.

Integer arithmetic

Instructions that perform integer arithmetic operations on values. Because we use two’s compliment integers, the signedness of the operands does not affect all operations. Where it does, the mnemonic will be prefixed with “u” or “s”, otherwise with “i”.

Where the size is < 64-bits, the least significant bits of the input value(s) are used, and the remainder of the output value is zeroed

i_neg

Performs integer negation on the provided value.
