 147         putting them in the symbol table.
 148         * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not
 149         M68KCOFF.
 150
 151         * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
 152         section.
 153
 154         * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
 155         comment_chars, line_comment_chars and line_seperator_chars
 156         consistently const, and always initialized them.  Included read.h.
 157
 158 Thu Nov  5 17:55:41 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
 159

 165
 166         * obj-coff.c (callj_table): Delete global variable.
 167         (obj_emit_relocations): Define it locally here, and only if
 168         TC_I960 is defined.
 169
 170         * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name.
 171         (m68k_ip): Don't warn about bignum used as float bit-pattern.
 172
 173         * obj-coff.c: Replaced ANSI and non-ANSI function declarations

 175
 176         * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length
 177         of 2.
 178
 179         * tc-i960.c: Missed a couple of 0->NO_RELOC conversions.
 180
 181         * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
 182         so widening works consistently.
 183
 184 Wed Oct 28 08:52:34 1992  Ken Raeburn  (raeburn@cygnus.com)
 185
 186         * version.c: Put conditional "const" before version_string, not
 187         before dummy function for VMS.  Now version 1.91.03.
 188
 189         * app.c (do_scrub_next_char): Need double-\ before `000' to show
 190         printed rep of null character.
 191
 192 Fri Oct 23 14:40:38 1992  Ian Lance Taylor  (ian@cygnus.com)
 193
 194         * obj-coffbfd.c (write_object_file): check return value of
 195         bfd_close_all_done.
 196
 197 Tue Oct 20 12:18:08 1992  Ian Lance Taylor  (ian@cygnus.com)
 198
 199         * Support for i386-sysv.
 200         obj-coffbfd.c (do_relocs_for, write_object_file): set segment
 201         addresses to reasonable sizes.  New define ZERO_BASED_SEGMENTS can
 202         be used to set them all to zero as was done before.
 203         (fill_section): segment addresses now set in write_object_file.
 204         (fill_section): Don't set STYP_NOLOAD for .bss section.
 205         (fixup_segment): 386 uses strange common symbol format.
 206         tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
 207         compatibility with SVR3.2 linker.

 214         * configure.in: differentiate between SunOS 4 and Solaris2 for Sun4
 215         hosts, use the sysv configuration for solaris2
 216
 217 Mon Oct  5 09:28:57 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 218
 219          fix i960+non-bfd coff bit rot.
 220         * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
 221         support for C source listings. (obj_coff_endef): look in the right
 222         part of the symbol for the symbol name
 223
 224         * tc-m68k.c (get_num): make it work for all segments, not just the
 225         first three.
 226

 235 Tue Sep 29 12:22:52 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 236
 237         * obj-coffbfd.c (write_object_file): don't fixup for the z8k
 238         * tc-z8k.c: lots of bug fixes
 239
 240 Tue Sep 29 10:51:55 1992  Ian Lance Taylor  (ian@cygnus.com)
 241
 242         * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
 243         #elif, since it is not supported by old compilers.
 244         ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
 245         couple of expressions in tc-m68k.c.
 246
 247 Mon Sep 28 21:18:24 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 248
 249         * read.c (cons): If NO_RELOC is defined, use it.
 250
 251         * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
 252
 253 Fri Sep 25 18:18:52 1992  Ian Lance Taylor  (ian@cygnus.com)
 254
 255         * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
 256         local labels to start with a .) and set REGISTER_PREFIX to %.
 257         tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.
 258
 259 Fri Sep 25 17:53:43 1992  John Gilmore  (gnu@cygnus.com)
 260
 261         * messages.c:  Comment changes.
 262

 264
 265         * as.h: Test if __STDC__ is defined only, don't test its value.
 266         * messages.c: If __STDC__ is not defined, define NO_STDARG.
 267

 272
 273 Tue Sep 22 13:02:07 1992  Sean Eric Fagan  (sef@cygnus.com)
 274
 275         * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
 276         sections starting from zero, rather than making them consecutive.
 277         This makes subsequent reloc calculations easier, esp if the object
 278         format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
 279         allocate lcomm in .data rather than in .bss.  It seems that some
 280         tools can't cope with a non-zero sized bss before linkage.
 281
 282 Tue Sep 22 15:10:51 1992  Ken Raeburn  (raeburn@cambridge.cygnus.com)
 283
 284         * tc-m68k.c: Replace "enum m68k_architecture" with "int"
 285         throughout.  That enum no longer means what we thought it meant.
 286
 287         * tc-m68k.c (md_assemble, md_parse_option): Handle new
 288         "-mno-688[58]1" options.

 290         * tc-m68k.c: Added CPU32 support.
 291
 292 Fri Sep 18 08:02:18 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 293
 294         * tc-m68k.c (m68k_ip): An(disp) is not pc relative.
 295
 296 Tue Sep 15 17:25:05 1992  Jim Wilson  (wilson@sphagnum.cygnus.com)
 297
 298         * Makefile.in (as.new): Remove dependence on LOCAL_LOADLIBES.

 302
 303         * Makefile.in (install): if $(tooldir) exists, install as in
 304         $(tooldir)/bin.
 305
 306 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
 307
 308         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
 309         .word is < -32768 or > 32767.  The -J flag causes the error to be
 310         ignored.  This is to catch over-sized switches generated by gcc on
 311         systems which don't support the broken .word hack.
 312         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
 313         write.c (fixup_segment): check for signed .word overflow if
 314         WARN_SIGNED_OVERFLOW_WORD.
 315
 316         * write.c (fixup_segment): fixed missing parens in expression
 317         checking for byte or word overflow.
 318
 319         * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD.
 320         obj-coffbfd.c (fixup_segment): check for signed .word overflow if
 321         WARN_SIGNED_OVERFLOW_WORD.
 322
 323         * obj-coffbfd.c (fixup_segment): fixed missing parens in
 324         expression checking for byte or word overflow.
 325
 326 Fri Sep 11 10:21:04 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 327
 328         Support for i386 coff
 329         * obj-coffbfd.h : added stuff
 330         * tc-i386.c (tc_coff_fix2rtype): new function
 331         * tc-i386.h : new coff defines
 332
 333 Thu Sep 10 09:23:15 1992  Ian Lance Taylor  (ian@cygnus.com)
 334
 335         * input-scrub.c (input_scrub_push): call input_file_begin, not
 336         input_scrub_begin.
 337         messages.c (as_perror): print ": " between the passed in error and
 338         the strerror, like perror does.
 339
 340 Wed Sep  9 11:06:25 1992  Ian Lance Taylor  (ian@cygnus.com)
 341
 342         * Makefile.in: use gas_target instead of modifying target_cpu.
 343         From Steve Chamberlain:
 344         Makefile.in: Handle m68*-*-coff*.
 345         read.c, read.h: add mult argument to s_space
 346
 347         * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
 348          Motorola and MIT syntax; gas can now assemble either type of
 349          file.
 350         tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
 351         From Steve Chamberlain:
 352         m68kcoff.mt: for m68k COFF.
 353         obj-coffbfd.c: (fixup_mdeps) added
 354          (size_section) removed bad sanity check
 355          (fill_section) added rs_machine_dependent case
 356          (write_object_file) call fixup_mdeps
 357          (fixup_segment) set fx_subsy to 0.

 713 Fri Mar 13 15:45:44 1992  K. Richard Pixley  (rich@cygnus.com)
 714
 715         * Makefile.in: install the man page.
 716
 717         * Makefile.in: pass down MAKEINFO explicitly on info.
 718
 719 Fri Mar 13 08:03:03 1992  Steve Chamberlain  (sac@thepub.cygnus.com)
 720
 721         * flonum-const.c: renamed flonum-konst.c to stop dos name
 722         conflict.
 723
 724 Thu Mar 12 04:42:38 1992  K. Richard Pixley  (rich@cygnus.com)
 725
 726         * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
 727           tc-m68k.h to te-sun3.h.
 728
 729 Wed Mar 11 23:32:42 1992  K. Richard Pixley  (rich@cygnus.com)
 730
 731         * configure.in: vxworks68 gets te-sun3.h.
 732
 733         * expr.c: remove limitation that local_labels_dollar or
 734           local_labels_fb must be < 10.
 735
 736         * symbols.c: remove local_labels_dollar, replace with a function
 737           interface for a sparse array.  All users adjusted.
 738
 739         * te-sun3.h: add LOCAL_LABELS_DOLLAR.
 740
 741 Fri Mar  6 21:57:18 1992  K. Richard Pixley  (rich@cygnus.com)
 742
 743         * Makefile.in: added check target.
 744
 745 Tue Mar  3 15:45:56 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
 746
 747         * Makefile.in: added tooldir and program_prefix.
 748
 749 Sun Mar  1 04:43:19 1992  Michael Tiemann  (tiemann@cygnus.com)
 750
 751         * write.{c,h} (fix_new): Make these declarations consistent.
 752
 753 Sat Feb 29 13:59:10 1992  Michael Tiemann  (tiemann@cygnus.com)
 754
 755         * Makefile.in (strerror.o): Add rule so that broken Sun make can
 756         work in subdirs.
 757
 758 Wed Feb 26 19:26:28 1992  Steve Chamberlain  (sac at thepub.cygnus.com)
 759
 760         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
 761
 762         * expr.c (operand): if can't work out what sort of operand it is,
 763         then look through FLT_CHARS for a hint.
 764
 765 Wed Feb 26 18:04:40 1992  K. Richard Pixley  (rich@cygnus.com)
 766
 767         * Makefile.in, configure.in: removed traces of namesubdir,
 768           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
 769           copyrights to '92, changed some from Cygnus to FSF.
 770
 771 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 772
 773         * expr.c: If an expression is single comma, then return with
 774         SEG_ABSENT rather than an error - since the sparc front end does
 775         really strange things with things like fbge,a
 776
 777         * as.h: include bfd.h if using many sections
 778         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
 779         local labels didn't work.
 780         * listing.c (list_symbol_table): don't core dump when there's no
 781         symbol there.
 782         * write.c, write.h: call fix_new with the right number of args on
 783         the H8.
 784         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
 785         errors nices
 786
 787 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 788
 789         * app.c: MRI compatibility - allow single quote to start a string.
 790         * as.c: fix typo recently introduced.
 791         * as.h : Don't include aout/reloc.h - it's not right for COFF!
 792         * expr.c: Much rewriting, to accomodate MRI syntax for
 793         expressions. Also easier to read now.
 794         * listing.c: Put back defuns
 795         * read.c: modified to accept MRI syntax, put back listing pseudo
 796         ops so that an assembler built with NO_LISTING ignores list ops
 797         rather than pukes.
 798         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
 799         machine is a SPARC or a 29K.
 800         * config/obj-aout.c: added s_sect pseudo op
 801         * config/obj-coffbfd.c: lints, set the filehdr flags right and
 802         fill in the timestamp.
 803         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
 804         anymore, define all the relocs which the tc-<x> bit will use so we
 805         can translate from them to the coff types.
 806         * config/tc-a29k.c: reloc_type isn't ane enum any more
 807         * config/tc-m68k.c: Added NO_RELOC definition.
 808
 809 Fri Feb 21 06:21:07 1992  K. Richard Pixley  (rich@rtl.cygnus.com)
 810
 811         * Makefile.in: put header files before C source for TAGS; remove
 812           references to non-existent syscalls.h.
 813
 814         * read.c, write.c subsegs.c: back out the .bss changes.
 815
 816         * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
 817
 818         * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
 819
 820         * a.out.h: removed.
 821
 822 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
 823
 824         * symbols.c (local_label_name): symbols now start with ^A.
 825
 826         * read.c, subsegs.c, write.c obj-coff.c: added handling of
 827           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
 828           generate these sections.  .align: will use NOP_OPCODE or 0
 829           for padding. This is just for being nice to the
 830           disassembler.
 831
 832         * expr.c (operand): changed to generate local label "\001L0"
 833           starting with a ^A so that it is recognized as a local label.
 834
 835         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
 836
 837         * tc-i386.c: tc-i386.c: added handling of the following opcodes:
 838           i/o opcodes - inb, inw, outb and outw.  string manipulation with
 839           att syntax - scmp, slod, smov, ssca, ssto.
 840
 841         * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
 842           to just after .file .
 843
 844           In obj_crawl_symbol_chain() where it tries to put the external
 845           symbols apart, with the condition:
 846             (!S_IS_DEFINED(symbolP) &&
 847              !S_IS_DEBUG(symbolP) &&
 848              !SF_GET_STATICS(symbolP))
 849           it was moving too many symbols out. So I switch it back to the
 850           condition:
 851             (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
 852
 853           In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
 854           so that we don't use the F_RELFLG which make the linker complain
 855           that somebody has stripped the relocation info.
 856
 857           Also, the AIX ld program require that the relocation table
 858           is sorted by r_vaddr like the standard ATT assembler does.
 859
 860           [he also changed the sizeof(struct ...)'s into the coff
 861           style FOOSZ macros.  I'm not sure this is right, but I can't
 862           remember why.  xoxorich.]

 864 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
 865
 866         * Makefile.in, configure.in, doc: use the doc.  Build it, install
 867           it, clean it, etc.
 868
 869 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
 870
 871         * read.c: white space and comments only.
 872
 873         * configure.in: use the new atof-ns32.c for ns32k.
 874
 875         * write.c: comment change only.
 876
 877         * tc-m88k.[hc]: pulled in from hack's unfinished work.  These
 878           aren't yet integrated.
 879
 880         * tc-i860.[hc]: blew off the dust.  Something must still be done
 881           about conflicting relocation types.
 882
 883         * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
 884           real thing.
 885
 886         * tc-i960.c, tc-sparc.c: white space and comments only.
 887
 888         * tc-a29k.h: delete duplicate macro definition.
 889
 890         * new file atof-ns32k.c copied from hack's last unreleased gas.
 891
 892 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
 893
 894         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
 895           rather than abort.
 896
 897         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
 898           ChangeLog's prior to this are sketchy at best.  I have logs.
 899           They just aren't ChangeLogs.
