+.IX Item "--change-pathname old=new"
+When converting debugging information using \fB\-\-debugging\fR, for
+every pathname that starts with \fIold\fR, replace the matching part
+by \fInew\fR. This is intented to map pathnames between different
+debugging tools, or when parts of the object file(s) had their
+pathnames recorded in a different build environment. Note that only
+leading directory name components might be changed that way, since the
+trailing filename could be recorded elsewhere as well (depending on the
+debugging format of the input file).
+.IP "\fB\-\-basename\fR"
+.IX Item "--basename"
+When converting debugging information using \fB\-\-debugging\fR, for
+every pathname, strip all leading directory information. This option
+takes precedence over any \fB\-\-change\-pathname\fR option. For some
+debugging formats that cannot handle long filenames, this options is
+implied (notably, some COFF debugging formats).

+ element in D1, an array its DT_ARY (its first DT_ARY in a
+ multi-dimensional array). In contrast, AVR COFF expects this most
+ important derived type specifier in the upmost Dn slot that is
+ allocated at all (i. e. that is != 0).
+
+ Generic COFF says that "Any symbol that satisfies more than one
+ condition [... for AUX entries] should have a union format in its
+ auxiliary entry." AVR COFF uses sepearate AUX entries for multiple
+ derived types, and in some cases (like the ISFCN one), even puts
+ the most important one into the last allocated AUX entry. We
+ join/split them here at the border as well. Note that when
+ generating AUX entries (where we need to split them), the n_numaux
+ field must already have been set up properly (e. g. in
+ binutils/wrcoff.c) since the entry renumbering and pointerization
+ would not work otherwise. Thus, we only split the information into
+ multiple records if n_numaux > 1. For similar reasons, we keep
+ n_numaux > 1 on input to keep the appropriate AUX entries
+ allocated, so a symbol can be reconstructed if it is being passed
+ through one of the GNU tools.
+
+ Note that this adjustment is called after the symbol itself has
+ been swapped in, but before the AUX entries are swapped in. This
+ is the only hook available that could swap (or merge) AUX entries
+ at all, so we have to operate on the external AUX entries still. */
