(open_output): Set it after bfd open succeeds.
* ldmisc.c (vfinfo): Test it.
Changes from Peter Hoogenboom, hoogen@cs.utah.edu:
* ldsym.c (write_file_locals): Set the BSF_FILE flag for object symbols.
* ldemul.c: Support was added to allow emulation-specific processing to occur.
This support was added primarily for linker stub generation in the elf32-hppa
gld.
(ldemul_finish, ldemul_create_output_section_statements): New functions.
* ldemul.h: Support was added to allow emulation-specific processing to occur.
(As described above.) Added finish and create_output_section_statements fields
to ld_emulation_xfer_struct structure.
* ldlang.c: Add calls to emulation-specific routines.
(lang_process): Add call to ldemul_create_output_section_statements function.
(lang_process): Add call to a emulation-specific routine (and
some processing after the call).
* Makefile.in (ALL_EMULATIONS): Added em_alpha.o.
(em_alpha.c): New target; use alpha.sh and alpha.sc.
* config/alphaosf.mh (NATIVE_LIB_DIRS, HOSTING_CRT0): Define.
* config/alpha.mt: New file.
* emulparams/alpha.sh: New file.
* scripttempl/alpha.sc: New file.
* scripttempl/elf.sc: Only use OTHER_READONLY_SECTIONS and
OTHER_READWRITE_SECTIONS if relocating. Shell variables are not
expanded within them.
* config/mipsb-elf32.mt: New file.
* emulparams/elf32mipb.sh: New file.
* Makefile.in (em_elf32mipb.c): New target.
INPUT(), then change the file type to lang_input_file_is_l_enum.
* ldgram.y: In input_list, change lang_input_file_is_file_enum to
lang_input_file_is_search_file_enum so objects brought in using
INPUT() do a path lookup.
* ld.h (flag_is_weak): Define.
* ldlang.c (print_symbol): Mention whether symbol is weak.
(print_input_section): Print weak symbols as globals.
* ldmain.c (refize): Do not zero out BSF_WEAK flag.
(enter_global_ref): Do not warn if a weak symbol redefines a
global symbol. Do not let a weak symbol redefine a common symbol.
(enter_file_symbols): Treat weak symbols as global symbols.
(subfile_wanted_p): Do not pull in an object file from a archive
just to resolve an undefined weak symbol.
* ldmisc.c (vfinfo): Don't needlessly malloc space after a fatal
error; the error might be that malloc has run out of space.
* ldsym.c (write_file_locals): Treat weak symbols as global.
* configure.in (i[34]86-*-sysv4*, i[34]86-*-elf*): New targets;
use i386-elf.
* config/i386v4.mh: New file; set NATIVE_LIB_DIRS to /usr/ccs/lib.
* config/i386-elf.mt: New file; set EMUL to elf_i386.
* emulparams/elf_i386.sh: New file.
* scripttempl/elf.sc: Use ${NOP} as filler (defaults to 0).
* Makefile.in (NATIVE_LIB_DIRS): Define to be empty.
(ALL_EMULATIONS): Add em_elf_i386.o.
(GENSCRIPTS): Pass NATIVE_LIB_DIRS as sixth argument.
(em_elf_i386.c): New target, like other em_*.c targets.
($(LD_PROG)): Pass $(CFLAGS) to $(CC).
* genscripts.sh: Accept NATIVE_LIB_DIRS as sixth argument. If
nonempty, and configured for native, add it to LIB_PATH.
* emultempl/hppaosf.em (ld_hppaosf_emulation): Correct name for PA
ELF emulation is "elf32-hppa" not "elf-big".
(hppaosf_before_parse): Remove unneeded processing of environment variables.
* scripttempl/hppaosf.sc: Include .hppa_linker_stubs sections in
.text segment of output file.
* emulparams/hppaosf.sh (OUTPUT_FORMAT): Use elf32-hppa.
parallel without colliding on yacc's static file names. Without the
stub rule, make will try to start two yacc's concurrently which
fails because of yacc's static file names.
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.
(mips-idt-ecoff*): Added trailing '*'.
* config/mips-idtl.mt: New file; use EMUL of mipsidtl.
* mipsidtl.sh: New file; like mipsidt.sh, but little endian.
* Makefile.in (ALL_EMULATIONS): Added em_mipsidtl.o.
* ldindr.c (add_indirect): Keep more information in the alias
symbol chain.
* ldlang.c (wild_doit): Don't inherit NEVER_LOAD section
attribute from an input section.
* ldmain.c (Q_enter_file_symbols): Common section is NEVER_LOAD by
default. (Q_enter_file_symbos): Indirect symbols now are known by
their section, not a special symbol flag.
* ldsym.c (write_file_locals): Indirect symbols aren't local.
(write_file_globals): Write the mapping for an indirect symbol.
* relax.c (build_it): When forced to write a NEVER_LOAD section,
fill it with zeros.
* ldlang.c (lang_relocate_globals): avoid possible hang with
undefined but unreferenced symbols.
* relax.c (relax_section): don't complain if the script file isn't
relaxable but -relax is set
* mips.sc-sh: Put .scommon sections into .sbss section.
* ldmain.c (subfile_wanted_p): Preserve section of common symbols,
rather than always putting them in bfd_com_section.
* ldlang.c (lang_common): If a common symbol is not in
bfd_com_section, put in a section of the same name, rather than
always putting it in section COMMON.
* ldmain.c (subfile_wanted_p): If we already have a common
definition of a symbol, don't necessarily pull in an object file
that provides a non-common definition.
* ldlex.l (COMMAND): Accept -EB and -EL command line arguments,
returning OPTION_EB and OPTION_EL. gcc passes these to a MIPS
linker.
* ldgram.y (OPTION_EB, OPTION_EL): New tokens.
(command_line_option): Accept and ignore OPTION_EB and OPTION_EL.
* mips.sc-sh: New file. Ultrix, and hopefully other MIPS ECOFF
targets, linker script.
* mipslit.sh: New file. Little endian MIPS emulation.
* config/mips-lit.mt: New file. Use mipslit emulation.
* configure.in (mips-dec-ultrix*): Use target mips-lit.
* Makefile.in (ALL_EMULATIONS): Added em_mipslit.o.
(em_mipslit.c): New target. Uses mipslit.sh.
* ldwrite.c: Removed perform_relocation, copy_and_relocate, and
write_norel. All linking is now done via write_relax. Call
ldsym_write before calling write_relax.
* relax.c: Added copyright.
(write_relax): Renamed from write_relaxnorel. Added relocateable
argument. seclet_dump renamed to bfd_seclet_link.
* relax.h: Added copyright.
