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

 413
 414         * Makefile.in (install): Install second copy in $(tooldir)/bin

 485 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 486
 487         * Makefile.in:  Change mkscript rule into one for ./mkscript

 498
 499         Major rewrite of how ld is configured.  The major idea
 500         is to use shell scripts to generate everything.
 501         * generic.em replaces ldtemplate.
 502         * Other *.em files replace various *.c files.
 503         A *.em file is a shell script that generates the corresponding
 504         ld__*.c file that implements an emulation.  This is usually
 505         a straight 'cat' of a here-document, possibly with substitutions.
 506         * Script files (*.sc) are places by *.sc-sh scripts.
 507         Again, these are simple shell scripts that 'cat'
 508         here-documents, usually with some substitutions.
 509         The output a *.sc-sh is a script file.
 510         * Each emulation is defined by a short shell script with
 511         extension *.sh that specifies the emulation-specific
 512         parameters (such as the name of the *.sh-sc and *.em
 513         files to use).
 514         * genscript.sh is the master shell script used to generate
 515         an emulation.  It is passed various argument, including
 516         the name a the emulation-speciic *.sh file that it
 517         "sources" to set variables to emulation-specifc parameters.
 518         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 519         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 520         * config/mh-foo:  Rename LDEMULATION names as appropriate
 521         (usually 'gldfoo' -> plain 'foo').
 522         * ldwrite.c:  Fixed a typo in a comment.
 523         * Makefile.in:  Major changes.  Removed some the sed
 524         magic to converts scripts, since that is now handled
 525         by genscripts.sh and the *.sc-sh scipt generators.
 526         * config.h:  Remove a bunch of macros defining emulations
 527         and targets.  This becomes one less file to edit when
 528         adding emulations or targets.
 529         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 530         emulation_name and target_name fields.
 531         * ldemul.c, ldemul.h:  Define some default functions used
 532         by most emulations (and remove from the *.em scripts).
 533         * ldemul.c (ldemul_choose_target):  Search the new
 534         ld_emulations array using a loop (instead of a hardwired
 535         nested if statement).
 536         Define the ld_emulation from the automatically-geenrated
 537         ldemul-list.h.  This means you no longer have to edit ldemul.c
 538         to add a new emulation.
 539         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 540         their expansions, since the former no longer exist.
 541         * PORTING:  A very rough first draft of a porting guide.
 542
 543         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 544         to be terminated by a new-line (instead of requiring a semicolon).
 545
 546 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 547
 548         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 549         tests for NULL pointers all over the place.
 550         * ldlang.c (lang_process): remember to relocate global symbols
 551         *after* relaxing has done it stuff.
 552
 553 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 554
 555         * config/mt-coff-h8300: use EMUL like everything else
 556         * ldlang.c: (print_padding_statement): print the right address.
 557         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms

 560 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 561
 562         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 563         * ldlang.c (print_data_statement): print the right address.
 564
 565 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 566
 567         * Makefile.in:  The rule for testing ld by re-linking itself
 568         via an intermediate -r link was moved to the ld1 rule
 569         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 570         which allows the bootstrap rule to work.
 571         * ldctor.c (find_constructors):  Don't create a constructor
 572         list if it is already defined (as would happen if ld is
 573         invoked by collect).
 574
 575 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 576
 577         * config/mh-sparc.h: now uses libgcc.a
 578         * ldmain.c: quit using exit
 579         * *sc: use *(COMMON) rather than [COMMON]
 580         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 581         to allow preprocessing of .l file.
 582         * Makefile.in: New ldlex.l mangling
 583         * ldexp.c (fold_binary): perform expressions with % and / in
 584         integer.
 585         * ldfile.c (open_a): open archives on VMS in a special way
 586
 587
 588 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 589
 590         * ldgram.y: map -M behave in the same way as -Map (sets file name
 591         to be "-".
 592         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 593         whether or not relaxing has been done.
 594         * ldmain.c: don't open a map file if it doesn't have a name
 595         * relax.c: all the brains have moved into bfd.
 596         * ldwrite.c: ammend comment

 601         partial link stage.
 602         * relax.c : added
 603         * config.h: if GNU960 defined, then default emulation mode is
 604         GLD960
 605         * ldexp.h, ldexp.c: map to file hooks
 606         * ldlang.c: map to file hooks
 607         * ldgram.y: added -Map -relax
 608         * ldlex.l: added -relax, -Map
 609         * ldmain.c: open map file
 610         * ldmisc.c: support for map file
 611         * ldwrite.c: new relax magic
 612
 613 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)

 627
 628         * Makefile.in:  Pass -y to bison.  (Again;
 629         accidentally deleted by Rich.)
 630         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 631
 632 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 633
 634         * ldindr.h: added to contain prototypes of ldindr.c

 640 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 641
 642         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 643           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 644           spaces following hyphens, bsd make can't cope.  added
 645           standards.text support and made it look like all the other
 646           makefiles.
 647
 648         * configure.in: configure now runs entirely in objdir so make file
 649           existence checks against ${srcdir}.  Mark this directory as
 650           target dependent.
 651
 652 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 653
 654         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 655           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 656           and mandir now keyed off datadir by default.
 657
 658 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 659
 660         * ldver.c:  Bumped version to 1.93.
 661         * Makefile.in:  Pass -y to bison.
 662
 663 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 664
 665         * config.h: h8 is now coff, not ieee
 666         * h8300hds.sc: reflect the same
 667
 668 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 669
 670         * ldver.c (ldversion()):  Update to 1.92.
 671         * ldctor.c: There are two places constructor sets
 672         can be defined.  One of them checked for an existing
 673         duplicate, the other didn't.  Unfortunately, the latter
 674         was called after the former ...
 675         So, factor out code for inserting a new element into
 676         constructor_name_list (after checking for a duplicate)
 677         into a new function add_constructor_name, and call
 678         it from both aforementioned places (ldlang_add_constructor
 679         and ldlang_check_for_constructors).
 680
 681 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 682
 683         * Makefile.in:  Rename .c files generated from ldtemplate
 684         to have names starting with ld__.  This helps 'make clean'.

 686 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 687
 688         * Makefile.in: Take out the version number for install
 689         * m88kbcs.sc: put in contructor blocks.
 690
 691 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 692
 693         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 694         parameter, a format, and an arg pointer, and rename it to
 695         vfinfo().  Write info() in terms of new vfinfo().
 696         New einfo() is the same as info(), except it writes to stderr.
 697         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 698         ldmisc.c:  Replace "error" calls to info() by new einfo().
 699
 700 Mon Nov 11 09:57:32 1991  Steve Chamberlain  (steve at cygnus.com)
 701
 702         * ldlex.l ldgram.y: made -V option do same as -v
 703         * Makefile.in: Added $(MINUS_G) flag so debugging can be

 707          i386 aout changes from Bob Kukura
 708         * Makefile.in, config.h: added i386aout support
 709         * configure.in: fixed /h-{myhost} typo
 710         * ldgram.y: -MM now gives more boring map.
 711         * ldlang.c: now does D_PAGED flag the right way.
 712         * ldsym.c: -MM flags does the right thing.
 713
 714 Sun Nov  3 15:00:03 1991  Per Bothner  (bothner at cygnus.com)
 715
 716         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 717         * ldlang.c (init_os):  Compensate for BFD change,
 718         where bfd_make_section now returns NULL for a duplicate
 719         section request, instead of the old section.

 721 Thu Oct 17 15:27:13 1991  Per Bothner  (bothner at cygnus.com)
 722
 723         * ldver.c: Bump to version 1.91 (consistent with binutils).
 724
 725 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 726
 727         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 728         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 729         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 730         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 731         Add or update copyright notices.
 732
 733 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 734
 735         * README: New file.
 736         * Makefile.in:  Changed installation directory name scheme
 737         to be consistent with gcc.  Also changed 'install'.
 738
 739 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 740
 741         * Makefile.in: new targets ld.mm, ld.me
 742
 743 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 744
 745         * Makefile.in, ldtemplate:  Need to use separate scripts
 746         for -n and -N options.  Yet more complication.
 747
 748 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 749
 750         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 751         work).  Add some lines to avoid Sun Make VPATH bugs.
 752
 753 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 754
 755         * news.sc: Add alignment for data segment.
 756         * ldtemplate: Add (yet another) script to get for -n or -N
 757         options.  (These need different alignment than ZMAGIC files.)
 758         * Makefile.in:  Add stuff for new foo.xn scripts.
 759         These are generated by replacing "ALIGN(0x...00)" by ".".
 760
 761 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 762
 763         * Makefile.in: new targets ld.ms, ld-index.ms
 764         ld.texinfo: remove tabs, other cleanups for texi2roff
 765
 766 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 767
 768         * ldmain.c (main): Make config.magic_demand_paged be true
 769         by default.  Don't the WP_TEXT and D_PAGED flags of
 770         output_bfd here; it's too late, so set it when output_bfd
 771         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 772         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 773         * ldlang.c: Remove some duplicate extern declarations.
 774         * ldgram.y: Fixes to -N and -n options.
 775         * Makefile.in:  Recognize upper case letters in sed script
 776         to remove assignments from script files.
 777         * ldtemplate:  Don't assukme that -N or -n options
 778         imply use of -r script.
 779         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 780
 781 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 782
 783         * ldtemplate: include bfd.h before sysdep.h.
 784
 785 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 786
 787         Restructure configuration scheme for bfd, binutils, ld.
 788
 789         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 790         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 791         Change some config names to match other dirs.
 792         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 793         get defined first.
 794         * config/:  Rename some config files to match up h-*.h names.
 795         Remove all the HOST_SYS definitions from the config files.
 796
 797 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 798
 799         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 800         * ldtemplate: Remove ldfile_add_library_path calls;
 801         just use the SEARCH_DIR commands in the script files.
 802         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 803         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 804         This is primarily intended for cross-linking, where you would
 805         place libaries in a different place than native libraries.
 806         Also, emulations made from ldtemplate now use $(srcdir).
 807         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 808         form; people can use the Makefile's LIB_PATH to override.
 809
 810 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 811
 812         * Makefile.in: fix target ld.dvi, add target ld.info
 813         ld.texinfo: make info filename ld.info
 814
 815 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 816
 817         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 818         Make).
 819         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 820         few BFD types & enums.
