* 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.
|
|
* Makefile.in (install): Remove $(tooldir)/bin/gld before creating
the link to it.
|
|
* ldmain.c, ldsym.c: Use new bfd_is_com_section macro rather than
checking for equality to bfd_com_section.
|
|
* 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.

hoogen@shafer.cs.utah.edu, don't reread library symbol tables.
|
|
* ldfile.c (ldfile_open_command_file): pass file name to
lex_push_file.
* ldlex.l, ldgram.y: tidy up, parse INCLUDE and NOLOAD
* ldlang.c (wild_doit): make output sections inherit NEVER_LOAD
attribute.
|
|
* m68kcoff.sc-sh: define _end as well as end, for consistency with
aout.sc-sh.
* configure.in: accept *-ericsson-ose for any m68k CPU.
* ldwrite.c (write_rel): don't always set SEC_HAS_CONTENTS flag
for each output section.
|
|
macro bfd_asymbol_bfd as appropriate.
* Makefile.in: Un-duplicate ldlex.c dependency.
* condigure.in: Replace my_host case table by sourcing
../bfd/configure.host. Allow std-host as the default.
* ldmisc.c: Change logic for C++ name demangling: There is
no initial '_' to remove from stab-derived function names.
|
|
* ld.texinfo: new doc.
* ldgram.y, ldlex.l: understand -y<symbol>
* ldmain.c (Q_enter_file_symbols): if had -y, lookup symbol and
print info. (add_ysym): new function.
* ldsym.h: (ldsym_type): new define SYM_Y.
|
|
ldlang.h, ldlex.h, ldmain.h, ldmisc.h, ldsym.h, ldver.h, ldwarn.h,
ldwrite.h, relax.h: Replace all uses of EXFUN and PROTO ansi-glue
macros with PARAMS. Recreational cleanup. Update copyrights.
|
|
* ldlang.c (lang_size_sections): don't change size and address for
SEC_SHARED_LIBRARY sections rather than for SEC_NEVER_LOAD
sections.
|
|
in scripts, makes counted contructor lists work again.
|
|
|
|
* Support for i386-sysv.
configure.in: check for i386-*-sysv* and i386-*-sco*.
i386coff.sc-sh: rewrote to support SVR3 by default.
ldctor.c (find_constructors): preserve stat_ptr.
ldlang.c (wild_doit): initialize vma and size of new output
section to corresponding input section. This is required for
shared library support.
(lang_size_sections): don't modify vma and size of sections which
are never loaded (for shared libraries).
ldwrite.c (copy_and_relocate): copy the contents of any section
which has contents, not just sections which are loaded (for shared
libraries).
|
|
we allocate.
|
|
* ldmisc.c (demangle,vfinfo): use the new underscore info in bfd to
to demangle symbols better
|
|
* ldlang.c (lang_finish): don't warn if -e start symbol does not
exist when linking with -r.
|
|
* aout.sc-sh, m68kcoff.sc-sh: set __bss_start to the start of the
.bss segment.
|
|
* ldmain.c (linear_library): don't even think about processing
an object file if it's already been done
|
|
|
|
mri.o, relax.o): Indicate dependence on ldgram.h.
* ld.h (strip_symbols_type): Add value STRIP_SOME.
* ldgram.y (OPTION_RETAIN_SYMBOLS_FILE): New terminal token.
(lang_add_keepsyms_file): New function.
* ldlex.l: Handle "-retain-symbols-file".
* ldsym.c (keepsyms_file, kept_syms): New vars.
(process_keepsyms): New functihon; reads file, marks symbols for saving.
(write_file_locals): File symbols should always be kept.
(ldsym_write): Warn about "-retain-symbols-file" overriding "-S" and "-s".
Process retain-symbols file before setting symtab.
* ldsym.h (SYM_KEEP): New flag for ldsym_type flags.
(keepsyms_file, kept_syms): Declare them.
* ldmain.c (main): Non-fatal errors should still cause non-zero exit status
even with -r.

Added initial support for the z8k
* z8ksim.em, z8ksim.sc-sh, z8ksim.sh: new files
* configure.in, Makefile.in: modified to reflect above
* ldlang.c (lang_check): when linking conflicting architectures,
make the output file reflect at least one of the bad inputs.
|
|
* Makefile.in (install): if $(tooldir) exists, install ld in
$(tooldir)/bin.
|

please let me know, or plug them in yourself.

* Makefile.in, m68kcoff.sh, m68kcoff.sc-sh, config/m68k-coff.mt:
added m68k-coff emulation mode, stolen from a29k emulation.
Almost certainly wrong, but perhaps better than sun3.
Also fixed an error message in configure.in so that it started with
'***' like the other error messages do.
|
|
|
|
* ldlex.l: Moved comment() to end, since some compilers
otherwise have problems with input() used before it is defined.

* Makefile.in: map "ld" through program_transform_name when
installing.
|
|
* ldmisc.c: Use new libiberty version of cplus_demangle().
|
|
todays (960 now always uses little endian ordering).
|
|
* gld960.em (gld960_choose_target): the target depends on
HOST_BIG_ENDIAN_P.
|
|
abs_output_section is what is required.
* ldwrite.c (ldwrite): use malloc to allocate the largest space
used, and pass that down.
* relax.c,relax.h (write_relaxnorel): use the passed malloc area rather
than alloca.

* configure.in: accept all m68K family members.
* Makefile.in: always create installation directories.
|
|
chars in filenames
* ldexp.c (exp_unop): pass down abs_output_section - now can have
unary -ve constants.
* ldlang.c (lang_finish): warn when an entry symbol supplied on
the command line can't be found.
|
|
* ldlang.c (lang_output_section_statement_lookup): initilize new
field. (wild_doit): if new field is not set, then stop output
section from being loadable.
(lang_enter_output_section_statement): set the field from the
NOLOAD keyword
* ldgram.y: new synax for NOLOAD. Removes a shift/reduce too.

|
* PORTING: Removed, merged into ldint.texinfo.

cdtest.exp: A test program (copied from libg++/test-install)
that tests that constructor and destructors are handled
corrrectly.
