6cc7365e2b * emultempl/elf32.em (gld${EMULATION_NAME}_check_ld_so_conf): New
static function, if ${host} = ${target}.
	(gld${EMULATION_NAME}_after_open): Call check_ld_so_conf to find a
	needed shared library if ${host} = $[target}.

169df8d594 * emultempl/elf32.em (gld${EMULATION_NAME}_check_needed): Check
the SONAME if it is available.
	(gld${EMULATION_NAME}_stat_needed): Use the SONAME, not the
	filename, when checking for conflicting library versions.  Don't
	assume that the suffix is only numbers and dots.

625489271d * emultempl/elf32.em (gld${EMULATION_NAME}_stat_needed): Warn if
it looks like we might be linking in two different versions of the
	same shared library.  Based on a patch from H J Lu <hjl@zoom.com>.

8055e7a883 * emultempl/elf32.em (global_stat): New file static variable.
(gld${EMULATION_NAME}_try_needed): Call stat_needed to make sure
	that the file has not already been included under another name.

uses it.

ed753c2049 Add Linux style directory searching.
* configure.tgt: Add i386lelf to targ_extra_emuls for
	i[345]86-*-linuxaout* and i[345]86-*-linuxoldld.  For
	i[345]86-*-linux*, set targ_emul to i386lelf, and add elf_i386 to
	targ_extra_emuls.
	* emulparams/i386lelf.sh: New file, a copy of elf_i386.sh.
	* emultempl/elf32.em: If TARGET_IS_i386lelf, use autoconf
	recommended mechanism to define DIR and struct dirent.
	(libcmp): New static function use only when TARGET_IS_i386lelf.
	(gld${EMULATION_NAME}_open_dynamic_archive): Likewise.
	* Makefile.in (ALL_EMULATIONS): Add ei386lelf.o
	(ei386lelf.c): New target.

7fb9ca5fc2 Let the user change the dynamic linker used by ELF code.
* ld.h (args_type): Add new field interpreter.
	* lexsup.c (parse_args): Add dynamic-linker to longopts, and
	handle it.
	* ldmain.c (main): Initialize command_line.interpreter to NULL.
	* emultempl/elf32.em (gld${EMULATION_NAME}_before_allocation): Get
	the ELF backend to return the .interp section.  If
	command_line.interpreter is not NULL, set the contents of .interp
	to it.
	* ld.texinfo: Mention -dynamic-linker.

2a9fa50cd8 Add support for ELF shared libraries.
* ld.h (ld_config_type): Add field dynamic_link.
	* ldmain.c (main): Initialize config.dynamic_link to false.  Warn
	on attempts to use -r with -relax, -call_shared or -s.
	* lexsup.c (longopts): Separate OPTION_CALL_SHARED from
	OPTION_NON_SHARED.  Add OPTION_IGNORE.  Adjust macro values
	accordingly.  Add "dy" and "non_shared" options.  Change "Qy" to
	OPTION_IGNORE for now.  Handle OPTION_CALL_SHARED and
	OPTION_NON_SHARED by setting dynamic_link field accordingly.
	Handle OPTION_IGNORE by ignoring it.  Clear dynamic_link field for
	-r and -Ur.
	* ldfile.c (ldfile_open_file): If config.dynamic_link is true, try
	opening a file with a .so extension first.
	* emultempl/elf32.em: New file.
	* emulparams/elf32_sparc.sh (TEXT_START_ADDR): Change to 0x10000.
	(NONPAGED_TEXT_START_ADDR): Likewise.
	(TEMPLATE_NAME): Define as elf32.
	(DATA_PLT): Define.
	* emulparams/elf_i386.sh (TEMPLATE_NAME): Define as elf32.
	* scripttempl/elf.sc: Add placement for new dynamic sections.
	Don't use CREATE_OBJECT_SYMBOLS.  Define _etext, _edata and _end
	outside of any section.  Don't use ALIGN(8); just let one section
	VMA follow another.  Put .dynbss in .bss.  Don't mention debugging
	sections; they'll be handled correctly anyhow.
	* Makefile.in (eelf_i386.c): Depend upon elf32.em, not generic.em.
