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).

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.
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.

* 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.
gld960.em, h8300hms.em, h8300xray.em, lnk960.em, st2000.em,
vanilla.em: Rename all (generated) ld__*.c files to em_.c.
This is one character shorter, and lets people build on
SVR3 system. (ld__h8300xray.[co] was the killer there;
h8300xray.sc-sh is also overlong, but seems harmless.)
Based on a patch from Jonathan Ryshpan <hitachi!amito!jon>.
* Makefile.in (clean): Fix typo mostclean -> mostlyclean.
* configure.in: Add host isc.
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.
Tue Aug 18 13:41:36 1992 Ian Lance Taylor (ian@cygnus.com)
* configure.in: accept all m68K family members.
* Makefile.in: always create installation directories.
(1) reflect current name of linker (now "ld", not "gld");
(2) fill in missing portion of a reference to full manual;
(3) fix old random typo spotted while proofing above.
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.
* h8300hms.sc-sh, h8300hms.em: get -r right.
(size_input_section): maintain the delta information.
* ldlang.h: add new field to struct to contain delta info.
* relax.c (relax_section): complain if input not relaxable.
* ldlex.l : add '_', ',' and '$' to chars which can appear at the
start of a filename
* ldexp.c: lint
* ldlang.c(open_output): set the target arch and machine as soon
as we can. (lang_size_sections): use new macros for setting vma
* ldwrite.c: lint
of YACC (since it is not longer used in the Makefile).
Remove HOSTING_* definitions that are subsumed by the
ones added to Makefile.in. Removed most definitions of CC.
* config/{sparc,news,hp300bsd,decstation}.mh: Removed;
These are no longer needed.
rules, since these are used when building a distribution.
* Makefile.in (ldlex.c): Don't re-direct output, since that
leaves a bogus output files if it fails.
* ldexp.c, ldlang.c, ldmain.c: reflect this
* ldver.c: bump version to 1.97.1
* ldindr.c (add_indirect): when an edict declaring an indirect
symbol is found, make sure that any ideas about the symbol being
common are changed if it now known to be defined.
* ldmain.c (linear_library): complain once if archive isn't
ranlibbed.
* ldlang.h, ldlang.c: make room for and initialize the complain
once field.
* ldmain.c (main): take out ./ from library path, and close file
before unlinking. Make multiple defs of a symbol create an
unexecable file.
* ldmisc.c: fatal errosrs delete output file
bfd too #.
* ldexp.c, ldlang.c: now build memory shape tree in obstacks
rather than with raw malloc, makes it easier to track where memory
is going.
* ldsym.h, ldsym.c: create obstack for all global symbols too.
* ldwrite.c (ldwrite): moved malloc so only used when needed.
* sa29200-sc.sh: added support for .lit, data1 and data2 sections.
magic to converts scripts, since that is now handled
by genscripts.sh and the *.sc-sh scipt generators.
* config.h: Remove a bunch of macros defining emulations
and targets. This becomes one less file to edit when
adding emulations or targets.
* ldemul.h (struct ld_emulation_xfer_struct): Add
emulation_name and target_name fields.
* ldemul.c, ldemul.h: Define some default functions used
by most emulations (and remove from the *.em scripts).
* ldemul.c (ldemul_choose_target): Search the new
ld_emulations array using a loop (instead of a hardwired
nested if statement).
Define the ld_emulation from the automatically-geenrated
ldemul-list.h. This means you no longer have to edit ldemul.c
to add a new emulation.
* ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by
their expansions, since the former no longer exist.
* PORTING: A very rough first draft of a porting guide.
to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
* config/mh-foo: Rename LDEMULATION names as appropriate
(usually 'gldfoo' -> plain 'foo').
is to use shell scripts to generate everything.
* Each emulation is defined by a short shell script with
extension *.sh that specifies the emulation-specific
parameters (such as the name of the *.sh-sc and *.em
files to use).
* genscript.sh is the master shell script used to generate
an emulation. It is passed various argument, including
the name a the emulation-speciic *.sh file that it
"sources" to set variables to emulation-specifc parameters.
is to use shell scripts to generate everything.
* generic.em replaces ldtemplate.
* Other *.em files replace various *.c files.
A *.em file is a shell script that generates the corresponding
ld__*.c file that implements an emulation. This is usually
a straight 'cat' of a here-document, possibly with substitutions.
* Script files (*.sc) are places by *.sc-sh scripts.
Again, these are simple shell scripts that 'cat'
here-documents, usually with some substitutions.
The output a *.sc-sh is a script file.
* ldmain.c: quit using exit
* *.sc: use *(COMMON) rather than [COMMON]
* ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
to allow preprocessing of .l file.
* Makefile.in: New ldlex.l mangling
* ldexp.c (fold_binary): perform expressions with % and / in
integer.
* ldfile.c (open_a): open archives on VMS in a special way
* lderror.c: forgot to check in from a long while ago
to be "-".
* ldsym.c, ldlang.c: remember that size of a section is dependent on
whether or not relaxing has been done.
* ldmain.c: don't open a map file if it doesn't have a name
* relax.c: all the brains have moved into bfd.
* ldwrite.c: ammend comment
(2) restructure machine dependencies into separate chapter
(3) replace pretty, but quick to become obsolete, graph of BFD platforms
vs architectures with extended excerpt from (and ref to ) objdump -i.
* ldfile.c: include ctype.h
* ldmain.c: include the requried prototype headers
* ldwrite.c: get_reloc_upper_bound has been renamed
bfd_get_reloc_upper_bound
* Makefile.in: punt "fundamental" mode because it breaks my emacs
macros. install using INSTALL_PROGRAM and INSTALL_DATA. remove
spaces following hyphens, bsd make can't cope. added
standards.text support and made it look like all the other
makefiles.
* configure.in: configure now runs entirely in objdir so make file
existence checks against ${srcdir}. Mark this directory as
target dependent.
Thu Dec 5 22:46:16 1991 K. Richard Pixley (rich at rtl.cygnus.com)
* Makefile.in: idestdir and ddestdir go away. Added copyrights
and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
and mandir now keyed off datadir by default.
parameter, a format, and an arg pointer, and rename it to
vfinfo(). Write info() in terms of new vfinfo().
New einfo() is the same as info(), except it writes to stderr.
* ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
ldmisc.c: Replace "error" calls to info() by new einfo().
i386 aout changes from Bob Kukura
* Makefile.in, config.h: added i386aout support
* configure.in: fixed /h-{myhost} typo
* ldgram.y: -MM now gives more boring map.
* ldlang.c: now does D_PAGED flag the right way.
* ldsym.c: -MM flags does the right thing.
* ldtemplate: Add (yet another) script to get for -n or -N
options. (These need different alignment than ZMAGIC files.)
* Makefile.in: Add stuff for new foo.xn scripts.
These are generated by replacing "ALIGN(0x...00)" by ".".
by default. Don't the WP_TEXT and D_PAGED flags of
output_bfd here; it's too late, so set it when output_bfd
is created (in ldlang.c). Also fix setting of EXEC_P flag
* ldlang.c (ldlang_open_output): Set output_bfd->flags here.
* ldlang.c: Remove some duplicate extern declarations.
* ldgram.y: Fixes to -N and -n options.
* Makefile.in: Recognize upper case letters in sed script
to remove assignments from script files.
* ldtemplate: Don't assukme that -N or -n options
imply use of -r script.
* mkscript.c: Tweaking to correctly handle \n and \\ in input.
* ldtemplate: Remove ldfile_add_library_path calls;
just use the SEARCH_DIR commands in the script files.
* Makefile.in: Add LIB_PATH macro, which if set is used to replace
the SEARCH_DIR commands in the scripts (using ugly sed magic).
This is primarily intended for cross-linking, where you would
place libaries in a different place than native libraries.
Also, emulations made from ldtemplate now use $(srcdir).
* ldglda29k.sc: Change SEARCH_DIR commands to a conventional
form; people can use the Makefile's LIB_PATH to override.
* ldm88k.sc: "Clean up" script, so that ldm88kUr.sc and ldm88kr.sc
can be automatically generated.
* ldemul.c, configure.in, config.h, Makefile.in:
Add support for Sony NewsOS3.
* Makefile.in: Re-do the way ldemulation scipts and structures
are done. do we only need one or two files for each emulation
target (a TARGET.sc and optionally TARGET.c, if ldtemplate
isn't suitable). This gets rid of lots of extra source files.
