+Somebody clever observed that, the more actual addresses you have in the

+address it needs, you should omit it from the debug info, to make
+linking faster.

+@code{SOFUN_ADDRESS_MAYBE_MISSING} indicates that a particular set of
+hacks of this sort are in use, affecting @code{N_SO} and @code{N_FUN}
+entries in stabs-format debugging information.  @code{N_SO} stabs mark
+the beginning and ending addresses of compilation units in the text
+segment.  @code{N_FUN} stabs mark the starts and ends of functions.
+
+@code{SOFUN_ADDRESS_MAYBE_MISSING} means two things:
+@itemize @bullet
+
+@item
+@code{N_FUN} stabs have an address of zero.  Instead, you should find the
+addresses where the function starts by taking the function name from
+the stab, and then looking that up in the minsyms (the linker/
+assembler symbol table).  In other words, the stab has the name, and
+the linker / assembler symbol table is the only place that carries
+the address.
+
+@item
+@code{N_SO} stabs have an address of zero, too.  You just look at the
