The following adds documentation for internal function details. I
have populated the internal function tables via macro expansion
of the internal-fn.def file, so it's quite boiler-plate and asks
for manual amending in more complicated places.
Without such a place it's quite difficult to tell people to document
things when they add new internal functions. We might want to split
the table into two, separating direct internal functions from others.
I have added some overall sentences related to internal functions
and builtins but left the API section as a FIXME.
I'm not sure we need a separate index - I have used IFN_ prefixes
which separates them nicely. Removing those would warrant a
separate index.
I've placed the contents after the GENERIC/GIMPLE chapters.
I have looked over the generated pdf and it looks reasonable.
Is this OK to push in this state? Or is "bad" documentation
worse than none?
Thanks,
Richard.

+@chapter Internal Functions in GENERIC and GIMPLE
+@cindex internal functions
+@cindex @file{internal-fn.def}
+
+In addition to builtin functions specified in @file{builtins.def} and
+friends the GENERIC and GIMPLE intermediate languages use calls with
+pre-defined semantics that are inline expanded to RTL rather than to
+calls or lowered at some point during optimziation.
+
+Internal functions work like tree operation codes in that they are
+not strongly typed so there are no variants like @code{BUILT_IN_SIN}
+and @code{BUILT_IN_SINF} but just a single @code{IFN_SIN}.
+
+Internal functions are declared in @file{internal-fn.def}.
