Note: read-only CSRs are not listed, as they do not participate in the definition of syntactic dependencies.

\section{Source and Destination Register Listings}
\label{sec:source-dest-regs}

This section provides a concrete listing of the source and destination registers for each instruction.
These listings are used in the definition of syntactic dependencies in Section~\ref{sec:memorymodel:dependencies}.

The term ``accumulating CSR'' is used to describe a CSR that is both a source and a destination register, but which carries a dependency only from itself to itself.

Instructions carry a dependency from each source register in the ``Source Registers'' column to each destination register in the ``Destination Registers'' column, from each source register in the ``Source Registers'' column to each CSR in the ``Accumulating CSRs'' column, and from each CSR in the ``Accumulating CSRs'' column to itself, except where annotated otherwise.

Key:

$^A$Address source register

$^D$Data source register

$^\dagger$The instruction does not carry a dependency from any source register to any destination register

$^\ddagger$The instruction carries dependencies from source register(s) to destination register(s) as specified
