3.2.10 Intermediate Dump Options
</H2>

<P>
The following options are provided for the purpose of retargetting
and debugging the compiler. They provide a means to dump the intermediate
code (iCode<A NAME="1213"></A>) generated by the compiler in human readable
form at various stages of the compilation process. More on iCodes
see chapter <A HREF="node187.html#sub:The-anatomy-of">9.1</A> ''The anatomy of the compiler''.

<UL>
<LI>[<B>--dumpraw<A NAME="1217"></A></B>] This option
will cause the compiler to dump the intermediate code into a file
of named <I>&lt;source filename&gt;.dumpraw</I> just after the intermediate
code has been generated for a function, i.e. before any optimizations
are done. The basic blocks<A NAME="1219"></A> at this stage ordered
in the depth first number, so they may not be in sequence of execution.
</LI>
<LI>[<B>--dumpgcse<A NAME="1220"></A></B>] Will create
a dump of iCodes, after global subexpression elimination<A NAME="1221"></A>,
into a file named <I>&lt;source filename&gt;.dumpgcse.</I>
</LI>
<LI>[<B>--dumpdeadcode<A NAME="1223"></A></B>] Will
create a dump of iCodes, after deadcode elimination<A NAME="1224"></A>,
into a file named <I>&lt;source filename&gt;.dumpdeadcode.</I>
</LI>
<LI>[<B>--dumploop<A NAME="1226"></A></B>] Will create
a dump of iCodes, after loop optimizations<A NAME="1227"></A>,
into a file named <I>&lt;source filename&gt;.dumploop.</I>
</LI>
<LI>[<B>--dumprange<A NAME="1229"></A></B>] Will
create a dump of iCodes, after live range analysis<A NAME="1230"></A>,
into a file named <I>&lt;source filename&gt;.dumprange.</I>
</LI>
<LI>[<B>--dumlrange<A NAME="1232"></A></B>] Will
dump the life ranges<A NAME="1233"></A> for all symbols.
</LI>
<LI>[<B>--dumpregassign<A NAME="1234"></A></B>] Will
create a dump of iCodes, after register assignment<A NAME="1235"></A>,
into a file named <I>&lt;source filename&gt;.dumprassgn.</I>
</LI>
<LI>[<B>--dumplrange<A NAME="1237"></A></B>] Will
create a dump of the live ranges of iTemp's
</LI>
<LI>[<B>--dumpall<A NAME="1238"></A></B>] Will cause
all the above mentioned dumps to be created.
