\chapter{The Compiler}
\subsection{File Types}
There are a number of different kinds of object files, distinguished
by extension.
\begin{center}
\begin{tabular}{l|l}
\emph{extension} & \multicolumn{1}{c}\emph{file type} \\\hline
\tt .oak & Oaklisp source file \\
\tt .omac & Macroexpanded Oaklisp source file \\
\tt .ou & Assembly file, not peephole optimized \\
\tt .oc & Assembly file, peephole optimized \\
\tt .oa & Assembled object file
\end{tabular}
\end{center}
\gv{compiler-from-extension}
\doc{The extension of the input files the compiler will read.
Default \df{".oak"}. This variable is in the compiler locale.}
\gv{compiler-to-extension}
\doc{The extension the the output files the compiler will produce.
Default \df{".oa"}. This variable is in the compiler locale.}
\gv{compiler-noisiness}
\doc{The amount of noise the compiler should produce; zero for none, 1
for a little, and 2 for a lot. Default value is 1, but the
\df{oakliszt} batch file compiler sets it to zero. This variable is
in the compiler locale.}
\subsection{Object File Formats}
\subsection{Compiler Internals}
Some compiler internals documentation. Very sketchy, just enough to
give people a vague idea of what the internal program representation
is and what the various passes are for.
