+/* ELF executable support for BFD.
+   Copyright 1991, 92, 93, 94, 95, 96, 97, 1998 Free Software Foundation, Inc.
+
+   Written by Fred Fish @ Cygnus Support, from information published
+   in "UNIX System V Release 4, Programmers Guide: ANSI C and
+   Programming Support Tools".  Sufficient support for gdb.
+
+   Rewritten by Mark Eichin @ Cygnus Support, from information
+   published in "System V Application Binary Interface", chapters 4
+   and 5, as well as the various "Processor Supplement" documents
+   derived from it. Added support for assembler and other object file
+   utilities.  Further work done by Ken Raeburn (Cygnus Support), Michael
+   Meissner (Open Software Foundation), and Peter Hoogenboom (University
+   of Utah) to finish and extend this.

+/* Problems and other issues to resolve.
+
+   (1)	BFD expects there to be some fixed number of "sections" in
+        the object file.  I.E. there is a "section_count" variable in the
+	bfd structure which contains the number of sections.  However, ELF
+	supports multiple "views" of a file.  In particular, with current
+	implementations, executable files typically have two tables, a
+	program header table and a section header table, both of which
+	partition the executable.
+
+	In ELF-speak, the "linking view" of the file uses the section header
+	table to access "sections" within the file, and the "execution view"
+	uses the program header table to access "segments" within the file.
+	"Segments" typically may contain all the data from one or more
+	"sections".
+
+	Note that the section header table is optional in ELF executables,
+	but it is this information that is most useful to gdb.  If the
+	section header table is missing, then gdb should probably try
+	to make do with the program header table.  (FIXME)
+
+   (2)  The code in this file is compiled twice, once in 32-bit mode and
+	once in 64-bit mode.  More of it should be made size-independent
+	and moved into elf.c.
+
+   (3)	ELF section symbols are handled rather sloppily now.  This should
+	be cleaned up, and ELF section symbols reconciled with BFD section
+	symbols.
+
+   (4)  We need a published spec for 64-bit ELF.  We've got some stuff here
+	that we're using for SPARC V9 64-bit chips, but don't assume that
+	it's cast in stone.
