c06e55d99a changes from gas-2.3/binutils-2.4 dist (details in branch log msgs, changelogs) 1994-05-27 16:58:05 +00:00
Ian Lance Taylor
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.

0a6ffe9cfd Remove ppc.em; do it all in nlmconv instead. 1994-03-12 03:19:27 +00:00

c361ce46c5 * configure.in (powerpc-*-elf*): New target; use ppc-elf32.
* config/ppc-elf32.mt: New file.
	* emulparams/elf32ppc.sh: New file.
	* emultempl/ppc.em: New file.
	* Makefile.in (ALL_EMULATIONS): Added em_elf32ppc.o.
	(em_elf32ppc.c): New target; uses elf32ppc.sh, ppc.em and elf.sc.
	(EMULATION_OFILES): Added dependencies on ldexp.h and ldlang.h.

8ddef5528d * ldfile.c (ldfile_open_command): Don't try .ld extension.
It wasn't documented (or likely used) and wastes time.
	(try_open): If EXTEN is empty, don't try it.

	* ldctor.c, lderror.c, ldexp.c, ldfile.c, ldindr.c, ldlang.c,
	ldlex.l, ldmain.c, ldmisc.c, ldsym.c, ldver.c, ldwarn.c,
	ldwrite.c, lexsup.c, mri.c, relax.c: Replace DEFUN macro calls
	with normal function declarations.

	* Move *.em to emultempl/*.em.  Move *.sh to emulparams/*.sh.
	Move *.sc-sh to scripttempl/*.sc.
	* {emultempl,emulparams,scripttempl}/README: New files.
	* sh.em, st2000.em, z8ksim.em, h8300hms.em, h8500hms.em: Files
	removed, replaced with generic.em.
	* h8300.sh, h8500.sh, h8300.sc, h8500.sc: Renamed from
	 h8[35]00hms.s[ch].  Change their contents to omit the "hms".

	* *.em (*_get_script): Return script name instead of script contents.
	* ldlang.c (lang_process): Change caller.

	* ldlex.l, ldgram.y: Recognize -m option.
	Check for input files after *all* options in grammar.
	* ldmain.c (main): Check for -m options.  Add default directory
	for -m.

	* mkscript.c: File removed.
	* genscripts.sh: Take two more parameters, tooldirlib and libdir,
	to add to the default LIB_PATH.
	Look for input files in the new subdirectories.
	Create the scripts in emulations subdirectory and don't filter
	them through mkscript.
	* configure.in: Make the emulations subdirectory.

	* Makefile.in: Account for all of the above changes.
	Remove unused .SUFFIXES.  Get libgcc.a path with gcc
	-print-libgcc-file-name instead of $(libdir)/libgcc.a.
	Put CFLAGS last in the compilation rules.
	Add -I../bfd to INCLUDES so sysdep.h is found.

	* ldfile.c (try_open): If opening without the extension fails,
	try with the extension even if -v or -V was given.
	had_script is imported (from ldgram.y), not exported.
