+Tasks:
+\begin{itemize}
+\item
+Utterly stomp out C functions' prologues and epilogues; i.e., the
+stuff to do with the C stack.
+\item
+Any other required tidying up.
+\end{itemize}
+
+HPPA specific notes:
+\begin{itemize}
+\item
+The HP linker is very picky about symbols being in the appropriate
+space (code vs. data).  When we mangle the threaded code to put the
+info tables just prior to the code, they wind up in code space
+rather than data space.  This means that references to *_info from
+un-mangled parts of the RTS (e.g. unthreaded GC code) get
+unresolved symbols.  Solution:  mini-mangler for .c files on HP.  I
+think this should really be triggered in the driver by a new -rts
+option, so that user code doesn't get mangled inappropriately.
+\item
+With reversed tables, jumps are to the _info label rather than to
+the _entry label.  The _info label is just an address in code
+space, rather than an entry point with the descriptive blob we
+talked about yesterday.  As a result, you can't use the call-style
+JMP_ macro.  However, some JMP_ macros take _info labels as targets
+and some take code entry points within the RTS.  The latter won't
+work with the goto-style JMP_ macro.  Sigh.  Solution: Use the goto
+style JMP_ macro, and mangle some more assembly, changing all
+"RP'literal" and "LP'literal" references to "R'literal" and
+"L'literal," so that you get the real address of the code, rather
+than the descriptive blob.  Also change all ".word P%literal"
+entries in info tables and vector tables to just ".word literal,"
+for the same reason.  Advantage: No more ridiculous call sequences.
+\end{itemize}
