* config/obj-elf.c (elf_file_symbol): When using ECOFF debugging,
	pass on the new file hook.

	* config/tc-alpha.c (alpha_fix_adjustable): Not quite the same as
	!alpha_force_relocation, as local LITERALs can be adjusted to be
	relative to the section.

* config/obj-elf.c (elf_frob_file): Move ECOFF debug processing to ...
	(elf_frob_file_after_relocs): ... here.  New function.
	* config/obj-elf.h (obj_from_file_after_relocs): New macro.
	* write.c (write_object_file): Call *frob_after_relocs after the
	call to write_relocs.

	* config/tc-alpha.c: Use new BFD_RELOC_ALPHA_ELF_LITERAL reloc.

	* config/tc-alpha.c (load_expression): Don't SET_VALUE on the section
	symbol, as this messes up linking.  Instead, expand the recursive call
	inline and change up the appropriate bits to get the 0x8000 offset
	in the reloc addend.

5ac34ac37e * Extensive changes to permit symbols to contain any expression
type and to delay the computation of the expression until the
	value is actually needed.  This permits setting symbols to values
	calculated based on object code size.  Expressions were changed to
	no longer be in a section, to stop the overloading of segment and
	expression type that previously occurred.

	Removed.
	(expr_section): Added (used for dummy symbols which hold
	intermediate expression values).

	sections now removed.

	sections and to simplify the parsing.
	* write.c (fix_new_internal): New static function.
	(fix_new): Removed sub_symbol argument.
	(fix_new_exp): New function, takes expression argument.
	* write.h: Prototype changes for fix_new and fix_new_exp.
