reading. Two sets of changes:
* New flags for debugging the readers.
--debug-dump=syms
--debug-dump=line
--debug-dump=frames
These (currently accepted but nonfunctional) are intended to
create output in the style of (that is, identical to)
/usr/bin/readelf --syms
/usr/bin/readelf --debug-dump=line
/usr/bin/readelf --debug-dump=frames
respectively. The plan is that flaws in these readers can then
be easily found by diff-ing the output against that from readelf.
Also, a new flag --trace-symtab-patt=<object filename pattern>
which is used to limit all debuginfo-related debug info to the
set of shared object names matching the given pattern. This
facilitates extracting the debuginfo details of one specific
shared object, which is usually what is required, rather than
having to wade through megabytes of junk from every object in
the process.
* Propagate the avma/svma/image address-naming scheme
(as described at the top of debuginfo.c) through large parts of
readelf.c and readdwarf.c.
