3427 leaves a bogus output files if it fails.
3429 * config/sparc.mh: Fix HOSTING_LIBS so it has a chance of working.

3509 Wed Apr 22 12:48:42 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3511 * ldlex.l: added CMDFILENAMECHAR state so that you can lex
3512 different sorts of filenames on the command line than in a script.
3514 Mon Apr 20 22:37:04 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3516 * Makefile.in: rework CFLAGS so that they can be passed on the

3538 without $(program_prefix), since that's what gcc expects.
3540 Sat Apr 4 17:44:06 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3542 * ldlex.l, ldgram.y, ldlex.h: Rewrote lexer. Now it's much nicer.

3610 * Makefile.in: Change mkscript rule into one for ./mkscript
3611 (for the sake of makes that don't realize they're the same).
3612 * PORTING: Add more details.
3613 * genscripts.sh: Add more tailorability of DATA_ALIGNMENT.
3615 Mon Feb 17 12:04:36 1992 Per Bothner (bothner at cygnus.com)
3617 * Makefile.in, and new files hp300bsd.sh, config/mh-hp300bsd,
3618 config/mt-hp300bsd: New port to hp300 running BSD.
3620 Sat Feb 15 13:59:54 1992 Per Bothner (bothner at cygnus.com)
3622 Major rewrite of how ld is configured. The major idea
3623 is to use shell scripts to generate everything.
3624 * generic.em replaces ldtemplate.
3625 * Other *.em files replace various *.c files.
3626 A *.em file is a shell script that generates the corresponding
3627 ld__*.c file that implements an emulation. This is usually
3628 a straight 'cat' of a here-document, possibly with substitutions.
3629 * Script files (*.sc) are places by *.sc-sh scripts.
3630 Again, these are simple shell scripts that 'cat'
3631 here-documents, usually with some substitutions.
3632 The output a *.sc-sh is a script file.
3633 * Each emulation is defined by a short shell script with
3634 extension *.sh that specifies the emulation-specific
3635 parameters (such as the name of the *.sh-sc and *.em
3637 * genscript.sh is the master shell script used to generate
3638 an emulation. It is passed various argument, including
3639 the name a the emulation-speciic *.sh file that it
3640 "sources" to set variables to emulation-specifc parameters.
3641 * config/mt-foo: Changed EMUL=GLDFOO_EMULATION_NAME
3642 to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
3643 * config/mh-foo: Rename LDEMULATION names as appropriate
3644 (usually 'gldfoo' -> plain 'foo').
3645 * ldwrite.c: Fixed a typo in a comment.
3646 * Makefile.in: Major changes. Removed some the sed
3647 magic to converts scripts, since that is now handled
3648 by genscripts.sh and the *.sc-sh scipt generators.
3649 * config.h: Remove a bunch of macros defining emulations
3650 and targets. This becomes one less file to edit when
3651 adding emulations or targets.
3652 * ldemul.h (struct ld_emulation_xfer_struct): Add
3653 emulation_name and target_name fields.
3654 * ldemul.c, ldemul.h: Define some default functions used
3655 by most emulations (and remove from the *.em scripts).
3656 * ldemul.c (ldemul_choose_target): Search the new
3657 ld_emulations array using a loop (instead of a hardwired
3658 nested if statement).
3659 Define the ld_emulation from the automatically-geenrated
3660 ldemul-list.h. This means you no longer have to edit ldemul.c
3661 to add a new emulation.
3662 * ldmain.c: Replace {GLD,LNK}960_EMULATION_NAME by
3663 their expansions, since the former no longer exist.
3664 * PORTING: A very rough first draft of a porting guide.
3666 * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
3667 to be terminated by a new-line (instead of requiring a semicolon).
3669 Mon Feb 10 16:21:02 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3671 * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
3672 tests for NULL pointers all over the place.
3673 * ldlang.c (lang_process): remember to relocate global symbols
3674 *after* relaxing has done it stuff.
3676 Thu Feb 6 11:40:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3678 * config/mt-coff-h8300: use EMUL like everything else
3679 * ldlang.c: (print_padding_statement): print the right address.
3680 * Makefile.in, config.h, ldemul.c: renamed h8300hds to h8300hms
3683 Tue Feb 4 15:28:01 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3685 * ldlex.l: Put pack -noinhibit-exec and -sort-common
3686 * ldlang.c (print_data_statement): print the right address.
3688 Thu Jan 30 17:51:53 1992 Per Bothner (bothner at cygnus.com)
3690 * Makefile.in: The rule for testing ld by re-linking itself
3691 via an intermediate -r link was moved to the ld1 rule
3692 instead of the ld2 rule. This allows ld2 and ld3 to be identical,
3693 which allows the bootstrap rule to work.
3694 * ldctor.c (find_constructors): Don't create a constructor
3695 list if it is already defined (as would happen if ld is
3696 invoked by collect).
3698 Wed Jan 29 08:35:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3700 * config/mh-sparc.h: now uses libgcc.a
3701 * ldmain.c: quit using exit
3702 * *sc: use *(COMMON) rather than [COMMON]
3703 * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
3704 to allow preprocessing of .l file.
3705 * Makefile.in: New ldlex.l mangling
3706 * ldexp.c (fold_binary): perform expressions with % and / in
3708 * ldfile.c (open_a): open archives on VMS in a special way
3711 Tue Jan 28 10:18:16 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3713 * ldgram.y: map -M behave in the same way as -Map (sets file name
3715 * ldsym.c, ldlang.c: remember that size of a section is dependent on
3716 whether or not relaxing has been done.
3717 * ldmain.c: don't open a map file if it doesn't have a name
3718 * relax.c: all the brains have moved into bfd.
3719 * ldwrite.c: ammend comment
3721 Fri Jan 24 14:23:46 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3723 * Makefile.in: added relax, also made three stage go through a
3726 * config.h: if GNU960 defined, then default emulation mode is
3728 * ldexp.h, ldexp.c: map to file hooks
3729 * ldlang.c: map to file hooks
3730 * ldgram.y: added -Map -relax
3731 * ldlex.l: added -relax, -Map
3732 * ldmain.c: open map file
3733 * ldmisc.c: support for map file
3734 * ldwrite.c: new relax magic
3736 Thu Dec 19 18:49:51 1991 John Gilmore (gnu at cygnus.com)
3738 * Makefile.in, config/tm-*.h: Clean up make output, only
3739 pass DEFAULT_EMULATION to ldmain.c.
3741 Wed Dec 18 15:02:47 1991 Per Bothner (bothner at cygnus.com)
3743 * ldver.c: Bump to version 1.94.
3745 Tue Dec 10 04:07:23 1991 K. Richard Pixley (rich at rtl.cygnus.com)
3747 * Makefile.in: infodir belongs in datadir.
3749 Mon Dec 9 16:26:43 1991 Per Bothner (bothner at cygnus.com)
3751 * Makefile.in: Pass -y to bison. (Again;
3752 accidentally deleted by Rich.)
3753 * news.sc, ldgld68k.sc: Define __end as well as _end.
3755 Sat Dec 7 17:19:26 1991 Steve Chamberlain (sac at rtl.cygnus.com)
3757 * ldindr.h: added to contain prototypes of ldindr.c
3758 * ldfile.c: include ctype.h
3759 * ldmain.c: include the requried prototype headers
3760 * ldwrite.c: get_reloc_upper_bound has been renamed
3761 bfd_get_reloc_upper_bound
3763 Fri Dec 6 23:29:26 1991 K. Richard Pixley (rich at rtl.cygnus.com)
3765 * Makefile.in: punt "fundamental" mode because it breaks my emacs
3766 macros. install using INSTALL_PROGRAM and INSTALL_DATA. remove
3767 spaces following hyphens, bsd make can't cope. added
3768 standards.text support and made it look like all the other
3771 * configure.in: configure now runs entirely in objdir so make file
3772 existence checks against ${srcdir}. Mark this directory as
3775 Thu Dec 5 22:46:16 1991 K. Richard Pixley (rich at rtl.cygnus.com)
3777 * Makefile.in: idestdir and ddestdir go away. Added copyrights
3778 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
3779 and mandir now keyed off datadir by default.
3781 Wed Dec 4 23:36:55 1991 Per Bothner (bothner at cygnus.com)
3783 * ldver.c: Bumped version to 1.93.
3784 * Makefile.in: Pass -y to bison.
3786 Mon Nov 25 18:28:40 1991 Steve Chamberlain (sac at cygnus.com)
3788 * config.h: h8 is now coff, not ieee
3789 * h8300hds.sc: reflect the same
3791 Thu Nov 14 19:55:09 1991 Per Bothner (bothner at cygnus.com)
3793 * ldver.c (ldversion()): Update to 1.92.
3794 * ldctor.c: There are two places constructor sets
3795 can be defined. One of them checked for an existing
3796 duplicate, the other didn't. Unfortunately, the latter
3797 was called after the former ...
3798 So, factor out code for inserting a new element into
3799 constructor_name_list (after checking for a duplicate)
3800 into a new function add_constructor_name, and call
3801 it from both aforementioned places (ldlang_add_constructor
3802 and ldlang_check_for_constructors).
3804 Wed Nov 13 15:17:43 1991 Per Bothner (bothner at cygnus.com)
3806 * Makefile.in: Rename .c files generated from ldtemplate
3807 to have names starting with ld__. This helps 'make clean'.
3809 Tue Nov 12 18:36:50 1991 Steve Chamberlain (sac at cygnus.com)
3811 * Makefile.in: Take out the version number for install
3812 * m88kbcs.sc: put in contructor blocks.
3814 Mon Nov 11 18:47:33 1991 Per Bothner (bothner at cygnus.com)
3816 * ldmisc.c, ldmisc.h: Re-write info() to take a filename
3817 parameter, a format, and an arg pointer, and rename it to
3818 vfinfo(). Write info() in terms of new vfinfo().
3819 New einfo() is the same as info(), except it writes to stderr.
3820 * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
3821 ldmisc.c: Replace "error" calls to info() by new einfo().
3823 Mon Nov 11 09:57:32 1991 Steve Chamberlain (steve at cygnus.com)
3825 * ldlex.l ldgram.y: made -V option do same as -v
3826 * Makefile.in: Added $(MINUS_G) flag so debugging can be
3829 Sun Nov 3 16:37:37 1991 Steve Chamberlain (steve at cygnus.com)
3830 i386 aout changes from Bob Kukura
3831 * Makefile.in, config.h: added i386aout support
3832 * configure.in: fixed /h-{myhost} typo
3833 * ldgram.y: -MM now gives more boring map.
3834 * ldlang.c: now does D_PAGED flag the right way.
3835 * ldsym.c: -MM flags does the right thing.
3837 Sun Nov 3 15:00:03 1991 Per Bothner (bothner at cygnus.com)
3839 * configure.in: Fixed typo. Also, a fix for hp300bsd.
3840 * ldlang.c (init_os): Compensate for BFD change,
3841 where bfd_make_section now returns NULL for a duplicate
3842 section request, instead of the old section.
3844 Thu Oct 17 15:27:13 1991 Per Bothner (bothner at cygnus.com)
3846 * ldver.c: Bump to version 1.91 (consistent with binutils).
3848 Wed Oct 16 12:27:08 1991 Per Bothner (bothner at cygnus.com)
3850 * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
3851 ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
3852 ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
3853 ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
3854 Add or update copyright notices.
3856 Mon Oct 14 23:55:27 1991 Per Bothner (bothner at cygnus.com)
3859 * Makefile.in: Changed installation directory name scheme
3860 to be consistent with gcc. Also changed 'install'.
3862 Mon Oct 14 17:30:02 1991 Roland H. Pesch (pesch at cygnus.com)
3864 * Makefile.in: new targets ld.mm, ld.me
3866 Mon Oct 14 17:27:24 1991 Per Bothner (bothner at cygnus.com)
3868 * Makefile.in, ldtemplate: Need to use separate scripts
3869 for -n and -N options. Yet more complication.
3871 Fri Oct 11 22:40:46 1991 John Gilmore (gnu at cygnus.com)
3873 * Makefile.in: Avoid using $< in explicit Make rules (it doesn't
3874 work). Add some lines to avoid Sun Make VPATH bugs.
3876 Fri Oct 11 16:42:22 1991 Per Bothner (bothner at cygnus.com)
3878 * news.sc: Add alignment for data segment.
3879 * ldtemplate: Add (yet another) script to get for -n or -N
3880 options. (These need different alignment than ZMAGIC files.)
3881 * Makefile.in: Add stuff for new foo.xn scripts.
3882 These are generated by replacing "ALIGN(0x...00)" by ".".
3884 Fri Oct 11 15:43:04 1991 Roland H. Pesch (pesch at cygnus.com)
3886 * Makefile.in: new targets ld.ms, ld-index.ms
3887 ld.texinfo: remove tabs, other cleanups for texi2roff
3889 Fri Oct 11 13:51:54 1991 Per Bothner (bothner at cygnus.com)
3891 * ldmain.c (main): Make config.magic_demand_paged be true
3892 by default. Don't the WP_TEXT and D_PAGED flags of
3893 output_bfd here; it's too late, so set it when output_bfd
3894 is created (in ldlang.c). Also fix setting of EXEC_P flag
3895 * ldlang.c (ldlang_open_output): Set output_bfd->flags here.
3896 * ldlang.c: Remove some duplicate extern declarations.
3897 * ldgram.y: Fixes to -N and -n options.
3898 * Makefile.in: Recognize upper case letters in sed script
3899 to remove assignments from script files.
3900 * ldtemplate: Don't assukme that -N or -n options
3901 imply use of -r script.
3902 * mkscript.c: Tweaking to correctly handle \n and \\ in input.
3904 Fri Oct 11 10:29:27 1991 Steve Chamberlain (steve at cygnus.com)
3906 * ldtemplate: include bfd.h before sysdep.h.
3908 Fri Oct 11 04:24:45 1991 John Gilmore (gnu at cygnus.com)
3910 Restructure configuration scheme for bfd, binutils, ld.
3912 * include/sys/h-*.h: Move to bfd/hosts/h-*.h.
3913 * configure.in: Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
3914 Change some config names to match other dirs.
3915 * *.c: Include bfd.h before sysdep.h, so ansidecl and PROTO()
3917 * config/: Rename some config files to match up h-*.h names.
3918 Remove all the HOST_SYS definitions from the config files.
3920 Tue Oct 8 16:00:57 1991 Per Bothner (bothner at cygnus.com)
3922 * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
3923 * ldtemplate: Remove ldfile_add_library_path calls;
3924 just use the SEARCH_DIR commands in the script files.
3925 * Makefile.in: Add LIB_PATH macro, which if set is used to replace
3926 the SEARCH_DIR commands in the scripts (using ugly sed magic).
3927 This is primarily intended for cross-linking, where you would
3928 place libaries in a different place than native libraries.
3929 Also, emulations made from ldtemplate now use $(srcdir).
3930 * ldglda29k.sc: Change SEARCH_DIR commands to a conventional
3931 form; people can use the Makefile's LIB_PATH to override.
3933 Tue Oct 8 14:51:21 1991 Roland H. Pesch (pesch at cygnus.com)
3935 * Makefile.in: fix target ld.dvi, add target ld.info
3936 ld.texinfo: make info filename ld.info
3938 Fri Oct 4 21:51:58 1991 John Gilmore (gnu at cygnus.com)
3940 * Makefile.in: Avoid using $< in non-suffix rules (breaks on Sun
3942 * ldfile.c, ldlang.c, ldmain.c, ldwrite.c: Cope with renames of a
3943 few BFD types & enums.
3950 version-control: never
