/* ELF executable support for BFD.
 
 
   Copyright (C) 1991-2015 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.
