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

 408
 409         * Makefile.in (install): Install second copy in $(tooldir)/bin
 410         without $(program_prefix), since that's what gcc expects.

 479
 480 Thu Feb 20 17:43:46 1992  Per Bothner  (bothner at cygnus.com)
 481
 482         * Makefile.in:  Change mkscript rule into one for ./mkscript
 483         (for the sake of makes that don't realize they're the same).
 484         * PORTING:  Add more details.
 485         * genscripts.sh:  Add more tailorability of DATA_ALIGNMENT.
 486
 487 Mon Feb 17 12:04:36 1992  Per Bothner  (bothner at cygnus.com)
 488

 492 Sat Feb 15 13:59:54 1992  Per Bothner  (bothner at cygnus.com)
 493
 494         Major rewrite of how ld is configured.  The major idea
 495         is to use shell scripts to generate everything.
 496         * generic.em replaces ldtemplate.
 497         * Other *.em files replace various *.c files.
 498         A *.em file is a shell script that generates the corresponding
 499         ld__*.c file that implements an emulation.  This is usually
 500         a straight 'cat' of a here-document, possibly with substitutions.
 501         * Script files (*.sc) are places by *.sc-sh scripts.
 502         Again, these are simple shell scripts that 'cat'
 503         here-documents, usually with some substitutions.
 504         The output a *.sc-sh is a script file.
 505         * Each emulation is defined by a short shell script with
 506         extension *.sh that specifies the emulation-specific
 507         parameters (such as the name of the *.sh-sc and *.em
 508         files to use).
 509         * genscript.sh is the master shell script used to generate
 510         an emulation.  It is passed various argument, including
 511         the name a the emulation-speciic *.sh file that it
 512         "sources" to set variables to emulation-specifc parameters.
 513         * config/mt-foo:  Changed EMUL=GLDFOO_EMULATION_NAME
 514         to EMUL=foo. (The GLDFOO_EMULATION_NAMEs have bee removed.)
 515         * config/mh-foo:  Rename LDEMULATION names as appropriate
 516         (usually 'gldfoo' -> plain 'foo').
 517         * ldwrite.c:  Fixed a typo in a comment.
 518         * Makefile.in:  Major changes.  Removed some the sed
 519         magic to converts scripts, since that is now handled
 520         by genscripts.sh and the *.sc-sh scipt generators.
 521         * config.h:  Remove a bunch of macros defining emulations
 522         and targets.  This becomes one less file to edit when
 523         adding emulations or targets.
 524         * ldemul.h (struct ld_emulation_xfer_struct):  Add
 525         emulation_name and target_name fields.
 526         * ldemul.c, ldemul.h:  Define some default functions used
 527         by most emulations (and remove from the *.em scripts).
 528         * ldemul.c (ldemul_choose_target):  Search the new
 529         ld_emulations array using a loop (instead of a hardwired
 530         nested if statement).
 531         Define the ld_emulation from the automatically-geenrated
 532         ldemul-list.h.  This means you no longer have to edit ldemul.c
 533         to add a new emulation.
 534         * ldmain.c:  Replace {GLD,LNK}960_EMULATION_NAME by
 535         their expansions, since the former no longer exist.
 536         * PORTING:  A very rough first draft of a porting guide.
 537
 538         * ldgram.y, ldlex.l, lexsup.c: Changes to allow an assignment
 539         to be terminated by a new-line (instead of requiring a semicolon).
 540
 541 Mon Feb 10 16:21:02 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 542
 543         * ldexp.c, ldlang.c: added new idea "abs_output_section", removes
 544         tests for NULL pointers all over the place.
 545         * ldlang.c (lang_process): remember to relocate global symbols
 546         *after* relaxing has done it stuff.
 547
 548 Thu Feb  6 11:40:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 549
 550         * config/mt-coff-h8300: use EMUL like everything else
 551         * ldlang.c: (print_padding_statement): print the right address.
 552         * Makefile.in, config.h, ldemul.c: renamed  h8300hds to h8300hms
 553
 554
 555 Tue Feb  4 15:28:01 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 556
 557         * ldlex.l: Put pack -noinhibit-exec and -sort-common
 558         * ldlang.c (print_data_statement): print the right address.
 559
 560 Thu Jan 30 17:51:53 1992  Per Bothner  (bothner at cygnus.com)
 561
 562         * Makefile.in:  The rule for testing ld by re-linking itself
 563         via an intermediate -r link was moved to the ld1 rule
 564         instead of the ld2 rule.  This allows ld2 and ld3 to be identical,
 565         which allows the bootstrap rule to work.
 566         * ldctor.c (find_constructors):  Don't create a constructor
 567         list if it is already defined (as would happen if ld is
 568         invoked by collect).
 569
 570 Wed Jan 29 08:35:39 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 571
 572         * config/mh-sparc.h: now uses libgcc.a
 573         * ldmain.c: quit using exit
 574         * *sc: use *(COMMON) rather than [COMMON]
 575         * ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
 576         to allow preprocessing of .l file.
 577         * Makefile.in: New ldlex.l mangling
 578         * ldexp.c (fold_binary): perform expressions with % and / in
 579         integer.
 580         * ldfile.c (open_a): open archives on VMS in a special way
 581
 582
 583 Tue Jan 28 10:18:16 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 584
 585         * ldgram.y: map -M behave in the same way as -Map (sets file name
 586         to be "-".
 587         * ldsym.c, ldlang.c: remember that size of a section is dependent on
 588         whether or not relaxing has been done.
 589         * ldmain.c: don't open a map file if it doesn't have a name
 590         * relax.c: all the brains have moved into bfd.
 591         * ldwrite.c: ammend comment
 592
 593 Fri Jan 24 14:23:46 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 594
 595         * Makefile.in: added relax, also made three stage go through a
 596         partial link stage.
 597         * relax.c : added
 598         * config.h: if GNU960 defined, then default emulation mode is
 599         GLD960
 600         * ldexp.h, ldexp.c: map to file hooks
 601         * ldlang.c: map to file hooks
 602         * ldgram.y: added -Map -relax
 603         * ldlex.l: added -relax, -Map
 604         * ldmain.c: open map file
 605         * ldmisc.c: support for map file
 606         * ldwrite.c: new relax magic
 607
 608 Thu Dec 19 18:49:51 1991  John Gilmore  (gnu at cygnus.com)
 609
 610         * Makefile.in, config/tm-*.h:  Clean up make output, only
 611         pass DEFAULT_EMULATION to ldmain.c.
 612

 619         * Makefile.in: infodir belongs in datadir.
 620
 621 Mon Dec  9 16:26:43 1991  Per Bothner  (bothner at cygnus.com)
 622
 623         * Makefile.in:  Pass -y to bison.  (Again;
 624         accidentally deleted by Rich.)
 625         * news.sc, ldgld68k.sc:  Define __end as well as _end.
 626
 627 Sat Dec  7 17:19:26 1991  Steve Chamberlain  (sac at rtl.cygnus.com)
 628
 629         * ldindr.h: added to contain prototypes of ldindr.c
 630         * ldfile.c: include ctype.h
 631         * ldmain.c: include the requried prototype headers
 632         * ldwrite.c: get_reloc_upper_bound has been renamed

 634
 635 Fri Dec  6 23:29:26 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 636
 637         * Makefile.in: punt "fundamental" mode because it breaks my emacs
 638           macros.  install using INSTALL_PROGRAM and INSTALL_DATA.  remove
 639           spaces following hyphens, bsd make can't cope.  added
 640           standards.text support and made it look like all the other
 641           makefiles.
 642
 643         * configure.in: configure now runs entirely in objdir so make file
 644           existence checks against ${srcdir}.  Mark this directory as
 645           target dependent.
 646
 647 Thu Dec  5 22:46:16 1991  K. Richard Pixley  (rich at rtl.cygnus.com)
 648
 649         * Makefile.in: idestdir and ddestdir go away.  Added copyrights
 650           and shift gpl to v2.  Added ChangeLog if it didn't exist. docdir
 651           and mandir now keyed off datadir by default.
 652
 653 Wed Dec  4 23:36:55 1991  Per Bothner  (bothner at cygnus.com)
 654
 655         * ldver.c:  Bumped version to 1.93.
 656         * Makefile.in:  Pass -y to bison.
 657
 658 Mon Nov 25 18:28:40 1991  Steve Chamberlain  (sac at cygnus.com)
 659
 660         * config.h: h8 is now coff, not ieee
 661         * h8300hds.sc: reflect the same
 662
 663 Thu Nov 14 19:55:09 1991  Per Bothner  (bothner at cygnus.com)
 664
 665         * ldver.c (ldversion()):  Update to 1.92.
 666         * ldctor.c: There are two places constructor sets
 667         can be defined.  One of them checked for an existing
 668         duplicate, the other didn't.  Unfortunately, the latter
 669         was called after the former ...
 670         So, factor out code for inserting a new element into
 671         constructor_name_list (after checking for a duplicate)
 672         into a new function add_constructor_name, and call
 673         it from both aforementioned places (ldlang_add_constructor
 674         and ldlang_check_for_constructors).
 675
 676 Wed Nov 13 15:17:43 1991  Per Bothner  (bothner at cygnus.com)
 677
 678         * Makefile.in:  Rename .c files generated from ldtemplate
 679         to have names starting with ld__.  This helps 'make clean'.
 680
 681 Tue Nov 12 18:36:50 1991  Steve Chamberlain  (sac at cygnus.com)
 682
 683         * Makefile.in: Take out the version number for install
 684         * m88kbcs.sc: put in contructor blocks.
 685
 686 Mon Nov 11 18:47:33 1991  Per Bothner  (bothner at cygnus.com)
 687
 688         * ldmisc.c, ldmisc.h:  Re-write info() to take a filename
 689         parameter, a format, and an arg pointer, and rename it to
 690         vfinfo().  Write info() in terms of new vfinfo().
 691         New einfo() is the same as info(), except it writes to stderr.
 692         * ldemul.c, ldexp.c, ldlang.c, ldlnk960.c, ldmain.c, ldwrite.c,
 693         ldmisc.c:  Replace "error" calls to info() by new einfo().

 696
 697         * ldlex.l ldgram.y: made -V option do same as -v
 698         * Makefile.in: Added $(MINUS_G) flag so debugging can be
 699         turned off
 700
 701 Sun Nov  3 16:37:37 1991  Steve Chamberlain  (steve at cygnus.com)
 702          i386 aout changes from Bob Kukura
 703         * Makefile.in, config.h: added i386aout support
 704         * configure.in: fixed /h-{myhost} typo
 705         * ldgram.y: -MM now gives more boring map.
 706         * ldlang.c: now does D_PAGED flag the right way.
 707         * ldsym.c: -MM flags does the right thing.

 710
 711         * configure.in:  Fixed typo.  Also, a fix for hp300bsd.
 712         * ldlang.c (init_os):  Compensate for BFD change,
 713         where bfd_make_section now returns NULL for a duplicate
 714         section request, instead of the old section.

 717
 718         * ldver.c: Bump to version 1.91 (consistent with binutils).
 719
 720 Wed Oct 16 12:27:08 1991  Per Bothner  (bothner at cygnus.com)
 721
 722         * Makefile.in, config.h, ld.h, ldemul.c, ldexp.c, ldexp.h,
 723         ldgram.y, ldlex.l, ldlnk960.c, ldmain.c, ldmisc.c, ldmisc.h,
 724         ldsym.c, ldsym.h, ldtemplate, ldvanilla.c, ldver.c, ldver.h,
 725         ldwarn.c, ldwarn.h, ldwrite.c, ldwrite.h, mkscript.c:
 726         Add or update copyright notices.
 727
 728 Mon Oct 14 23:55:27 1991  Per Bothner  (bothner at cygnus.com)
 729
 730         * README: New file.
 731         * Makefile.in:  Changed installation directory name scheme
 732         to be consistent with gcc.  Also changed 'install'.
 733
 734 Mon Oct 14 17:30:02 1991  Roland H. Pesch  (pesch at cygnus.com)
 735
 736         * Makefile.in: new targets ld.mm, ld.me
 737
 738 Mon Oct 14 17:27:24 1991  Per Bothner  (bothner at cygnus.com)
 739
 740         * Makefile.in, ldtemplate:  Need to use separate scripts
 741         for -n and -N options.  Yet more complication.
 742
 743 Fri Oct 11 22:40:46 1991  John Gilmore  (gnu at cygnus.com)
 744
 745         * Makefile.in:  Avoid using $< in explicit Make rules (it doesn't
 746         work).  Add some lines to avoid Sun Make VPATH bugs.
 747
 748 Fri Oct 11 16:42:22 1991  Per Bothner  (bothner at cygnus.com)
 749
 750         * news.sc: Add alignment for data segment.
 751         * ldtemplate: Add (yet another) script to get for -n or -N
 752         options.  (These need different alignment than ZMAGIC files.)
 753         * Makefile.in:  Add stuff for new foo.xn scripts.
 754         These are generated by replacing "ALIGN(0x...00)" by ".".
 755
 756 Fri Oct 11 15:43:04 1991  Roland H. Pesch  (pesch at cygnus.com)
 757
 758         * Makefile.in: new targets ld.ms, ld-index.ms
 759         ld.texinfo: remove tabs, other cleanups for texi2roff
 760
 761 Fri Oct 11 13:51:54 1991  Per Bothner  (bothner at cygnus.com)
 762
 763         * ldmain.c (main): Make config.magic_demand_paged be true
 764         by default.  Don't the WP_TEXT and D_PAGED flags of
 765         output_bfd here; it's too late, so set it when output_bfd
 766         is created (in ldlang.c).  Also fix setting of EXEC_P flag
 767         * ldlang.c (ldlang_open_output):  Set output_bfd->flags here.
 768         * ldlang.c: Remove some duplicate extern declarations.
 769         * ldgram.y: Fixes to -N and -n options.
 770         * Makefile.in:  Recognize upper case letters in sed script
 771         to remove assignments from script files.
 772         * ldtemplate:  Don't assukme that -N or -n options
 773         imply use of -r script.
 774         * mkscript.c:  Tweaking to correctly handle \n and \\ in input.
 775
 776 Fri Oct 11 10:29:27 1991  Steve Chamberlain  (steve at cygnus.com)
 777
 778         * ldtemplate: include bfd.h before sysdep.h.
 779
 780 Fri Oct 11 04:24:45 1991  John Gilmore  (gnu at cygnus.com)
 781
 782         Restructure configuration scheme for bfd, binutils, ld.
 783
 784         * include/sys/h-*.h:  Move to bfd/hosts/h-*.h.
 785         * configure.in:  Revise to symlink sysdep.h to ../bfd/hosts/h-xxx.h.
 786         Change some config names to match other dirs.
 787         * *.c:  Include bfd.h before sysdep.h, so ansidecl and PROTO()
 788         get defined first.
 789         * config/:  Rename some config files to match up h-*.h names.
 790         Remove all the HOST_SYS definitions from the config files.
 791
 792 Tue Oct  8 16:00:57 1991  Per Bothner  (bothner at cygnus.com)
 793
 794         * ldexp.h, ldlang.h: Change enum boolean -> enum bfd_boolean.
 795         * ldtemplate: Remove ldfile_add_library_path calls;
 796         just use the SEARCH_DIR commands in the script files.
 797         * Makefile.in: Add LIB_PATH macro, which if set is used to replace
 798         the SEARCH_DIR commands in the scripts (using ugly sed magic).
 799         This is primarily intended for cross-linking, where you would
 800         place libaries in a different place than native libraries.
 801         Also, emulations made from ldtemplate now use $(srcdir).
 802         * ldglda29k.sc:  Change SEARCH_DIR commands to a conventional
 803         form; people can use the Makefile's LIB_PATH to override.
 804
 805 Tue Oct  8 14:51:21 1991  Roland H. Pesch  (pesch at cygnus.com)
 806
 807         * Makefile.in: fix target ld.dvi, add target ld.info
 808         ld.texinfo: make info filename ld.info
 809
 810 Fri Oct  4 21:51:58 1991  John Gilmore  (gnu at cygnus.com)
 811
 812         * Makefile.in:  Avoid using $< in non-suffix rules (breaks on Sun
 813         Make).
 814         * ldfile.c, ldlang.c, ldmain.c, ldwrite.c:  Cope with renames of a
 815         few BFD types & enums.
