   1 Sun Sep 13 20:30:10 1992  Ian Lance Taylor  (ian@cygnus.com)
   2
   3         * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
   4         .word is < -32768 or > 32767.  The -J flag causes the error to be
   5         ignored.  This is to catch over-sized switches generated by gcc on
   6         systems which don't support the broken .word hack.
   7         as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
   8         write.c (fixup_segment): check for signed .word overflow if
   9         WARN_SIGNED_OVERFLOW_WORD.
  10
  11         * write.c (fixup_segment): fixed missing parens in expression
  12         checking for byte or word overflow.

  19         the strerror, like perror does.

 362
 363         * read.c, obj-coffbfd.c : fix h8300 specific bit rot
 364
 365         * expr.c (operand): if can't work out what sort of operand it is,
 366         then look through FLT_CHARS for a hint.

 369
 370         * Makefile.in, configure.in: removed traces of namesubdir,
 371           -subdirs, $(subdir), $(unsubdir), some rcs triggers.  Forced
 372           copyrights to '92, changed some from Cygnus to FSF.

 374 Tue Feb 25 14:17:15 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 375
 376         * expr.c: If an expression is single comma, then return with
 377         SEG_ABSENT rather than an error - since the sparc front end does
 378         really strange things with things like fbge,a
 379
 380         * as.h: include bfd.h if using many sections
 381         * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
 382         local labels didn't work.
 383         * listing.c (list_symbol_table): don't core dump when there's no
 384         symbol there.
 385         * write.c, write.h: call fix_new with the right number of args on
 386         the H8.
 387         * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
 388         errors nices

 390 Sat Feb 22 12:26:28 1992  Steve Chamberlain  (sac at rtl.cygnus.com)
 391
 392         * app.c: MRI compatibility - allow single quote to start a string.
 393         * as.c: fix typo recently introduced.
 394         * as.h : Don't include aout/reloc.h - it's not right for COFF!
 395         * expr.c: Much rewriting, to accomodate MRI syntax for
 396         expressions. Also easier to read now.
 397         * listing.c: Put back defuns
 398         * read.c: modified to accept MRI syntax, put back listing pseudo
 399         ops so that an assembler built with NO_LISTING ignores list ops
 400         rather than pukes.
 401         * write.c, write.h: fixs - only keep a reloc type in a fix if the target
 402         machine is a SPARC or a 29K.
 403         * config/obj-aout.c: added s_sect pseudo op
 404         * config/obj-coffbfd.c: lints, set the filehdr flags right and
 405         fill in the timestamp.
 406         * config/obj-coffbfd.h: Since we don't include aout/reloc.h
 407         anymore, define all the relocs which the tc-<x> bit will use so we
 408         can translate from them to the coff types.
 409         * config/tc-a29k.c: reloc_type isn't ane enum any more
 410         * config/tc-m68k.c: Added NO_RELOC definition.

 413
 414         * Makefile.in: put header files before C source for TAGS; remove
 415           references to non-existent syscalls.h.
 416
 417         * read.c, write.c subsegs.c: back out the .bss changes.
 418
 419 Fri Feb 21 01:08:48 1992  Minh Tran-Le (TRANLE@INTELLICORP.COM)
 420
 421         * symbols.c (local_label_name): symbols now start with ^A.
 422
 423         * read.c, subsegs.c, write.c obj-coff.c: added handling of
 424           `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
 425           generate these sections.  .align: will use NOP_OPCODE or 0
 426           for padding. This is just for being nice to the
 427           disassembler.
 428
 429         * expr.c (operand): changed to generate local label "\001L0"
 430           starting with a ^A so that it is recognized as a local label.
 431
 432         * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
 433
 434 Fri Feb 21 01:08:48 1992  K. Richard Pixley  (rich@cygnus.com)
 435
 436         * Makefile.in, configure.in, doc: use the doc.  Build it, install
 437           it, clean it, etc.
 438
 439 Tue Feb 18 02:21:25 1992  K. Richard Pixley  (rich at cygnus.com)
 440
 441         * read.c: white space and comments only.
 442
 443         * configure.in: use the new atof-ns32.c for ns32k.
 444
 445         * write.c: comment change only.
 446
 447 Mon Feb 17 07:51:06 1992  K. Richard Pixley  (rich at cygnus.com)
 448
 449         * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
 450           rather than abort.
 451
 452         * nearly everything.  flush ChangeLog, package as gas-1.92.1.
 453           ChangeLog's prior to this are sketchy at best.  I have logs.
 454           They just aren't ChangeLogs.
