 120         This is one character shorter, and lets people build on

 492
 493         * Makefile.in:  Change mkscript rule into one for ./mkscript

 503 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 504
 505         Major rewrite of how ld is configured.  The major idea
 506         is to use shell scripts to generate everything.
 507         * generic.em replaces ldtemplate.
 508         * Other *.em files replace various *.c files.
 509         A *.em file is a shell script that generates the corresponding
 510         ld__*.c file that implements an emulation.  This is usually
 511         a straight 'cat' of a here-document, possibly with substitutions.
 512         * Script files (*.sc) are places by *.sc-sh scripts.
 513         Again, these are simple shell scripts that 'cat'
 514         here-documents, usually with some substitutions.
 515         The output a *.sc-sh is a script file.
 516         * Each emulation is defined by a short shell script with
 517         extension *.sh that specifies the emulation-specific
 518         parameters (such as the name of the *.sh-sc and *.em
 519         files to use).
 520         * genscript.sh is the master shell script used to generate
 521         an emulation.  It is passed various argument, including
 522         the name a the emulation-speciic *.sh file that it
 523         "sources" to set variables to emulation-specifc parameters.
 524         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 525         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 526         * config/mh-foo:  Rename LDEMULATION names as appropriate
 527         (usually 'gldfoo' -> plain 'foo').
 528         * ldwrite.c:  Fixed a typo in a comment.
 529         * Makefile.in:  Major changes.  Removed some the sed
 530         magic to converts scripts, since that is now handled
 531         by genscripts.sh and the *.sc-sh scipt generators.
 532         * config.h:  Remove a bunch of macros defining emulations
 533         and targets.  This becomes one less file to edit when
 534         adding emulations or targets.
 535         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 536         emulation_name and target_name fields.
 537         * ldemul.c, ldemul.h:  Define some default functions used
 538         by most emulations (and remove from the *.em scripts).
 539         * ldemul.c (ldemul_choose_target):  Search the new
 540         ld_emulations array using a loop (instead of a hardwired
 541         nested if statement).
 542         Define the ld_emulation from the automatically-geenrated
 543         ldemul-list.h.  This means you no longer have to edit ldemul.c
 544         to add a new emulation.
 545         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 546         their expansions, since the former no longer exist.
 547         * PORTING:  A very rough first draft of a porting guide.
 548
 549         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 550         to be terminated by a new-line (instead of requiring a semicolon).
 551
 552 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 553
 554         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 555         tests for NULL pointers all over the place.
 556         * ldlang.c (lang_process): remember to relocate global symbols
 557         *after* relaxing has done it stuff.
 558
 559 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 560
 561         * config/mt-coff-h8300: use EMUL like everything else
 562         * ldlang.c: (print_padding_statement): print the right address.
 563         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms

 566 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 567
 568         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 569         * ldlang.c (print_data_statement): print the right address.
 570
 571 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 572
 573         * Makefile.in:  The rule for testing ld by re-linking itself
 574         via an intermediate -r link was moved to the ld1 rule
 575         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 576         which allows the bootstrap rule to work.
 577         * ldctor.c (find_constructors):  Don't create a constructor
 578         list if it is already defined (as would happen if ld is
 579         invoked by collect).
 580
 581 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 582
 583         * config/mh-sparc.h: now uses libgcc.a
 584         * ldmain.c: quit using exit
 585         * *sc: use *(COMMON) rather than [COMMON]
 586         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 587         to allow preprocessing of .l file.
 588         * Makefile.in: New ldlex.l mangling
 589         * ldexp.c (fold_binary): perform expressions with % and / in
 590         integer.
 591         * ldfile.c (open_a): open archives on VMS in a special way
 592
 593
 594 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 595
 596         * ldgram.y: map -M behave in the same way as -Map (sets file name
 597         to be "-".
 598         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 599         whether or not relaxing has been done.
 600         * ldmain.c: don't open a map file if it doesn't have a name
 601         * relax.c: all the brains have moved into bfd.
 602         * ldwrite.c: ammend comment

 607         partial link stage.
 608         * relax.c : added
 609         * config.h: if GNU960 defined, then default emulation mode is
 610         GLD960
 611         * ldexp.h, ldexp.c: map to file hooks
 612         * ldlang.c: map to file hooks
 613         * ldgram.y: added -Map -relax
 614         * ldlex.l: added -relax, -Map
 615         * ldmain.c: open map file
 616         * ldmisc.c: support for map file
 617         * ldwrite.c: new relax magic

 633
 634         * Makefile.in:  Pass -y to bison.  (Again;
 635         accidentally deleted by Rich.)
 636         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 637
 638 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 639

 646 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 647
 648         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 649           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 650           spaces following hyphens, bsd make can't cope.  added
 651           standards.text support and made it look like all the other
 652           makefiles.
 653
 654         * configure.in: configure now runs entirely in objdir so make file
 655           existence checks against ${srcdir}.  Mark this directory as
 656           target dependent.
 657
 658 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 659
 660         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 661           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 662           and mandir now keyed off datadir by default.
 663
 664 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 665
 666         * ldver.c:  Bumped version to 1.93.

 668
 669 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 670
 671         * config.h: h8 is now coff, not ieee
 672         * h8300hds.sc: reflect the same
 673
 674 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 675
 676         * ldver.c (ldversion()):  Update to 1.92.
 677         * ldctor.c: There are two places constructor sets
 678         can be defined.  One of them checked for an existing
 679         duplicate, the other didn't.  Unfortunately, the latter
 680         was called after the former ...
 681         So, factor out code for inserting a new element into
 682         constructor_name_list (after checking for a duplicate)
 683         into a new function add_constructor_name, and call
 684         it from both aforementioned places (ldlang_add_constructor
 685         and ldlang_check_for_constructors).
 686
 687 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 688
 689         * Makefile.in:  Rename .c files generated from ldtemplate

 693
 694         * Makefile.in: Take out the version number for install

 696
 697 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 698
 699         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 700         parameter, a format, and an arg pointer, and rename it to
 701         vfinfo().  Write info() in terms of new vfinfo().
 702         New einfo() is the same as info(), except it writes to stderr.
 703         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 704         ldmisc.c:  Replace "error" calls to info() by new einfo().

 708         * ldlex.l ldgram.y: made -V option do same as -v
 709         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 710         turned off
 711
 712 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 713          i386 aout changes from Bob Kukura
 714         * Makefile.in, config.h: added i386aout support
 715         * configure.in: fixed /h-{myhost} typo
 716         * ldgram.y: -MM now gives more boring map.
 717         * ldlang.c: now does D_PAGED flag the right way.
 718         * ldsym.c: -MM flags does the right thing.
 719
 720 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 721
 722         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 723         * ldlang.c (init_os):  Compensate for BFD change,
 724         where bfd_make_section now returns NULL for a duplicate
 725         section request, instead of the old section.

 727 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 728
 729         * ldver.c: Bump to version 1.91 (consistent with binutils).
 730
 731 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)

 737         Add or update copyright notices.
 738
 739 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 740
 741         * README: New file.
 742         * Makefile.in:  Changed installation directory name scheme
 743         to be consistent with gcc.  Also changed 'install'.
 744
 745 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 746
 747         * Makefile.in: new targets ld.mm, ld.me
 748
 749 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 750
 751         * Makefile.in, ldtemplate:  Need to use separate scripts
 752         for -n and -N options.  Yet more complication.
 753
 754 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 755
 756         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 757         work).  Add some lines to avoid Sun Make VPATH bugs.
 758
 759 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 760
 761         * news.sc: Add alignment for data segment.
 762         * ldtemplate: Add (yet another) script to get for -n or -N
 763         options.  (These need different alignment than ZMAGIC files.)
 764         * Makefile.in:  Add stuff for new foo.xn scripts.
 765         These are generated by replacing "ALIGN(0x...00)" by ".".
 766
 767 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 768
 769         * Makefile.in: new targets ld.ms, ld-index.ms
 770         ld.texinfo: remove tabs, other cleanups for texi2roff
 771
 772 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 773
 774         * ldmain.c (main): Make config.magic_demand_paged be true
 775         by default.  Don't the WP_TEXT and D_PAGED flags of
 776         output_bfd here; it's too late, so set it when output_bfd
 777         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 778         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 779         * ldlang.c: Remove some duplicate extern declarations.
 780         * ldgram.y: Fixes to -N and -n options.
 781         * Makefile.in:  Recognize upper case letters in sed script
 782         to remove assignments from script files.
 783         * ldtemplate:  Don't assukme that -N or -n options
 784         imply use of -r script.
 785         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 786
 787 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 788
 789         * ldtemplate: include bfd.h before sysdep.h.
 790
 791 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 792
 793         Restructure configuration scheme for bfd, binutils, ld.
 794
 795         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 796         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 797         Change some config names to match other dirs.
 798         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 799         get defined first.
 800         * config/:  Rename some config files to match up h-*.h names.
 801         Remove all the HOST_SYS definitions from the config files.
 802
 803 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 804
 805         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 806         * ldtemplate: Remove ldfile_add_library_path calls;
 807         just use the SEARCH_DIR commands in the script files.
 808         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 809         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 810         This is primarily intended for cross-linking, where you would
 811         place libaries in a different place than native libraries.
 812         Also, emulations made from ldtemplate now use $(srcdir).
 813         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 814         form; people can use the Makefile's LIB_PATH to override.
 815
 816 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 817
 818         * Makefile.in: fix target ld.dvi, add target ld.info
 819         ld.texinfo: make info filename ld.info
 820
 821 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 822
 823         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 824         Make).
 825         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 826         few BFD types & enums.
