\subsection{PowerPC (64bit) Calling Convention}

\paragraph{Overview}

\begin{itemize}
\item Word size is 64 bits
\item Big endian (MSB) and litte endian (LSB) operating modes.
\item Apple Mac OS X/Darwin PPC is specified in "Mac OS X ABI Function Call Guide"\cite{ppcMacOSX}. It uses Big Endian (MSB).
\item Linux PPC 64-bit ABI is specified in "64-bit PowerPC ELF Application Binary Interface Supplement"\cite{ppcelf64abi} which is based on "System V ABI".
\end{itemize}


\paragraph{\product{dyncall} support}

\product{Dyncall} supports PowerPC (64bit) Big Endian and Little Endian ELF ABIs on System V systems (Linux, etc.), including syscalls. Mac OS X is not supported.
