1 Mon Nov 25 17:26:22 1991 Steve Chamberlain (sac at cygnus.com)
3 * as.c: (perform_an_assembly_pass): moved declaration of i to
4 avoid a syntax error. Now always create the three default
5 sections when in MANY_SEGMENTS mode.
6 * as.h: New improved way of specifying MANY_SEGMENTS
7 * configure.in: hds object format is now coff-bfd
8 * subsegs.h: add line numbers and section stuff to the
9 segment_info structure. (But go back later and fix.. this is
13 Thu Oct 24 17:25:59 1991 Steve Chamberlain (steve at rtl.cygnus.com)
15 * config/obj-coff.c (obj_coff_dim): Allows newline to end a
18 Mon Oct 21 09:25:33 1991 Steve Chamberlain (steve at rtl.cygnus.com)
20 * configure.in: added ebmon entry.
21 * output-file.c (output_file_create, output_file_close) added
23 * write.c: more bfd support
24 * config/obj-coff.c config/obj-coff.h use bfd for swapping
26 * tc-a29k: added the reloc types we support now
29 Mon Oct 14 11:44:03 1991 Roland H. Pesch (pesch at cygnus.com)
31 * doc/Makefile (as.ms): one more sed workaround for texi2roff
32 (as.mm, as.me): new targets
34 Fri Oct 11 18:18:37 1991 Roland H. Pesch (pesch at cygnus.com)
36 * doc/Makefile: new targets as.info, as.ms
37 doc/as.texinfo: minor changes for texi2roff-2
38 Makefile.in: revise 'doc' target.
40 Fri Jan 4 12:48:22 EST 1991 Jay Fenlason (hack@ai.mit.edu)
42 * messages.c Moved as_perror from input-scrub.c Modified the
43 error messages to look better.
45 * output-file.c Don't call as_fatal, just call exit()
47 expr.c Slightly improve checking for foo-foo case in
48 clean_up_expression(). Detect foo: bar: ... foo-bar...
50 Tue Dec 4 16:29:20 EST 1990 Jay Fenlason (hack@ai.mit.edu)
52 * m68k.c Fixed an obscure bug involving AOFF mode with a
53 large constant displacement (Was forgetting to output the
56 make-gas.com Added a three line patch from Eric Youngdale that
57 makes it possible to submit make-gas.com to a batch queue.
59 Wed Nov 21 15:07:51 EST 1990 Jay Fenlason (hack@ai.mit.edu)
61 * vms.c (VMS_TBT_Routine_END) Add a four line patch from
64 Tue Nov 13 14:02:15 EST 1990 Jay Fenlason (hack@ai.mti.edu)
66 * vms-dbg.c (VMS_DBG_record()) Another one character patch from
69 Mon Oct 29 15:49:21 EST 1990 Jay Fenlason (hack@ai.mit.edu)
71 * read.c Replace some as_warn calls with as_bad.
73 Fri Oct 26 15:21:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
75 * i386.c, i860.c, ns32k.c Add const changes.
77 Mon Oct 22 14:04:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
79 * sparc.c Add const changes.
81 * make-gas.com define const= for VMS, since many older versions of
82 GCC don't work correctly with const under VMS.
84 Thu Oct 18 12:44:11 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
86 * i860.c i860-opcode.h Added patches from rgb@mcc.com
88 * read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
89 Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
90 patches, so debugging GCC output now works.
92 * hash.c (hash_grow) Remember to blank out the wall entry in the new
93 hash table. This is important on systems where malloc() returns
96 Tue Oct 16 10:11:35 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
98 * output-file.c (output_file_create) if output filename is given as
101 * m68k.c Finally get the PCREL code to work right. Add relaxation of
102 PCREL stuff This small fix from Ken Woodland
103 (kenny%datacube.uucp@uunet.uu.net).
105 * m68k.c Added some const declarations to constants. (md_relax_table,
106 md_pseudo_table, etc. . .)
108 Thu Oct 11 11:15:10 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
110 * Makefile, read.c, write.c Include the i860 port.
111 (New files i860.c i860-opcode.h i860.h)
113 * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
116 * (all over) Raeburn's const hacking. This reduces the data-space size by
117 declaring many tables, etc, as 'const'.
119 Mon Oct 22 22:48:22 1990 John Gilmore (gnu at cygint)
121 Make gas work if you turn on the know() checks.
123 * app.c: Only pass a single space through: the one after
124 the opcode. All other whitespace is removed, to match the
125 expectations of the parser in read.c.
127 * as.h: Remove obsolete comments. Remove JF's NDEBUG so
128 that know() can really work if you turn it on. Make
129 SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
131 * expr.c (operand): Change BITS_PER_INT to 8*sizeof(int).
133 * input-scrub.c: strlen("\0") doesn't return 1...
134 (as_where): Add space after line number in errors, like gcc.
136 * m68k.c (s_bss): Fake .bss into data section 255.
137 We can't cope with a real "BSS section" yet, but we can at
138 least do the right thing less efficiently (with lots of
141 * read.c: Turn lots of as_warn()'s into as_bad()'s.
143 * read.h (SKIP_WHITESPACE): Replace last instance of ASSERT()
146 * sparc.c (s_seg): We can't put frags into the BSS segment
147 yet, so just fake bss seg as 255th data segment.
149 * vax.c: Remove \'s from continued macro *parameters*. These
150 must have been added after the last time someone turned on
153 * write.c (relax_segment): Refine what we know() about the
154 symbols referenced during relaxation.
156 * Makefile (OTHER_ALIGN): Remove, handled in tables now.
157 Flip options a bit. These options really ought to go
160 Sun Oct 21 03:57:21 1990 John Gilmore (gnu at cygint)
164 * expr.c, write.c: Missing semicolon after know().
166 * write.c (fixup_segment): Allow pc-relative accesses to undefined
167 external symbols. Previously this would turn off pc-rel calc
168 of displacement, while leaving pc-rel opcode alone, botching.
170 * m68k.c (m68k_ip): Allow pc-relative effective addresses
171 for source operands. "pea" instructions are a good example
172 where we can shorten from abs long to pc+16bit.
173 (md_convert_frag): Fix "JBSR" comments to refer to "JSR", the
174 actual instruction. Insert comments about bug in 68000 bcc
175 and dbcc long code (that doesn't get exercised much). Add
176 comments about long pcrel displacements for -pic. Remove
177 "this code has not been tested" comment.
178 (md_estimate_size_before_relax): Now that fixup_segment
179 doesn't shortcircuit pc-relative fixups for undefined symbols,
180 only output them if -pic; else turn them absolute, which is
181 slightly faster. More JBSR->JSR comments.
182 (md_parse_options): Parse -pic.
184 Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint)
186 * Make sparc assembler more compatible with Sun assembler.
187 sparc.c: reformat pseudo-op table to match main table.
188 (md_assemble): Add SPECIAL_CASE_FDIV to assemble FDIV*
189 instructions as fdiv followed by fmovs to get around chip bug.
190 (s_common, s_seg): Accept "bss" section name.
191 (md_assemble): Handle "set" instructions with absolute
192 operands, that only take one instruction rather than two.
193 sparc-opcode.h (fdiv*): Mark instructions "S"pecial.
194 subsegs.c (subseg_change): Move tail pointer too.
195 symbols.c (colon): Allow new definitions to override .comm symbols,
196 as in VMS. Sun CC depends on this.
197 write.c (new_fix): Always take r_type argument, not just on sparc.
198 Chain fixP's in order, using tail pointer, so relocation
199 records come out in forward order like Sun as. Remove SPARC
201 write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
203 * am29k.c: Use s_align_bytes rather than a local copy.
205 * read.c (s_align): Rather than ifdef it, make two functions,
206 s_align_bytes and s_align_ptwo. Individual pseudo-op tables
207 can call whichever one they like.
209 * write.c (append): Move from append.c to here.
210 append.c: Remove file.
212 * Makefile (MDSRC, mdsrc): Easy way to edit all md.c's.
213 Fix options. Add option for -DDEBUG for know() and assert().
214 Remove append.c, am29k.h. Don't build special read-sparc.o.
215 Remove sparc.h. "make clean" removes am29k .o's. Add
216 dependencies on reloc.h.
218 Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint)
220 * Generalize sparc extensions to relocation info. Gas now
221 keeps relocation information internally in a different format
222 than how it is stored in the resulting .o. md_ri_to_bytes()
223 converts to external format. md_reloc_size says how large
224 each relocation record is in external format.
225 sparc.h: Remove this file. Rename to reloc.h. Rename struct
226 to reloc_info_generic.
227 reloc.h: Add relocation types for AMD 29000.
228 read.c, write.c: Always call fix_new with reloc-type argument.
229 write.c (emit_relocations): Make md_ri_to_bytes write directly
230 to output area rather than overwriting its argument then
232 md.h: Declare md_reloc_size and md_ri_to_bytes.
233 i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
234 (md_reloc_size): Specify correct value.
235 (md_ri_to_bytes): Convert format from internal to external.
237 write.c (write_object_file): Call md_section_align() which
238 rounds section sizes up if desired.
239 sparc.c (md_section_align): Round to 8 byte boundary.
240 i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align): Nop.
242 Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint)
244 Changes in support of the AMD 29000 version of gas.
246 * am29k-opcode.h: Add dummy entry to end so we can examine
247 item N+1 without exceeding table.
249 * am29k.h: New include file, derived from sparc.h. Kludged
250 together, still needs major work to get relocation working.
252 * am29k.c: New file, derived from sparc.c.
253 Put 29k-specific ASM29K pseudo-ops into table.
254 Change comment_chars to ASM29K.
255 Change s_seg to s_use.
256 Change s_sparc_align to s_29k_align, default operand to 4.
257 (define_some_regs): Define special register names.
258 (md_begin): Preprocess opcode table to mash together all
259 the variants of single opcodes. This simplifies later handling.
260 Call define_some_regs to preset special reg names.
261 (parse_operand): Add, parses out an operand from a stmt.
262 (machine_ip): Simplify, since 29K is simpler asm language.
263 Handle the various keyletters in the opcode table.
266 Handle include files in the assembler, with a .include
268 * as.h (input_scrub_include_file): declare.
269 * as.c (perform_an_assembly_pass): Avoid buffer hacking.
270 Start us off in text segment.
271 * read.c (read_a_source_file): Take a name as argument,
272 internalize all buffer handling. Don't start a new text
273 subsegment on each entry. Actually use the start and end
274 pointers returned by input_scrub_next_buffer.
275 (s_include): Call input_scrub_include_file for .include.
276 * input-scrub.c: Fix comments.
277 (struct input_save): Add, for saving state at .include.
278 (input_scrub_push, input_scrub_pop): Add, push & pop state.
279 (input_scrub_begin): Initialize next_saved_file.
280 (input_scrub_end): Free buffer.
281 (input_scrub_include_file): Add, to include a file.
282 (input_scrub_close): Add, to close a file.
283 (input_scrub_next_buffer): Set buffer-start address for
284 caller. If we hit EOF and were included, pop to previous file.
285 * input-file.c: Remove old includes. Remove old file-descriptor
286 hacking code, that was commented out.
287 (struct saved_file): Add, for saving state at .include.
288 (input_file_push, input_file_pop): Add, push & pop state.
289 (input_file_open): Don't buffer all files in one place.
290 (input_file_close): Add, close input file.
291 * input-file.h: Declare new functions.
292 * app.c: (struct app_save): Add, for saving state at .include.
293 (app_push, app_pop): Add, push and pop state.
294 (do_scrub_next_char): Move its static state variables out so
295 they can be saved and restored.
298 * app.c: Allow overriding of character meanings by machine
299 dependent strings. Avoid wiring character constants into app.c.
300 (do_scrub_begin): New meanings override old ones, not "OR" them.
301 Only handle /* comments if / is not already in use.
302 (do_scrub_next_char): Reorganize mass of nested if's
303 into a switch for speed. Don't assume ';' is line terminator.
304 Reorganize switch on characters, into a switch on their (machine-
305 dependent) lexer table meanings.
308 Encapsulate knowledge of segment types in fewer places.
309 This allows us to add the "SEG_REGISTER" type, as well as
310 providing flexibility for eventual COFF/ELF support.
311 * struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
312 set_symbol_segment, set_symbol_segment_keep_ext,
313 segment_name): Define macros to encapsulate this info.
314 * as.h: Remove externs for seg_name, seg_N_TYPE, N_TYPE_seg.
315 * symbols.c (symbol_new): Change 'type' arg to 'seg'.
316 * expr.c, i386.c, m68k.c, ns32k.c, read.c, symbols.c, vax.c,
318 * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of
319 md_estimate_size_before_relax.
320 * expr.c, read.c: Change 'type' arg to symbol_new.
321 * read.c, symbols.c, vax.c, write.c: Move md.h to end of includes.
324 Allow expressions to evaluate to registers.
325 * as.h: Add SEG_REGISTER.
326 * struc-symbol.h: Add fake N_REGISTER type.
327 * subseg.c: Add types to tables.
328 * expr.c (operand): Symbols of SEG_REGISTER type are
329 immediately evaluated like those of SEG_ABSOLUTE.
330 (clean_up_expression): Clean up SEG_REGISTER exprs.
333 Allow machine descriptions to cleanly extend the set of
335 * expr.c (operand): Call md_operand before rejecting an
336 operand as unacceptable.
338 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
339 * am29k.c (md_operand): Use this for %% and & prefix operators.
342 Allow machine descriptions to cleanly permit symbols to be
343 predefined upon first usage.
344 * symbols.c (symbol_find_or_make): Call md_undefined_symbol
345 before making an undefined symbol.
347 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
348 * am29k.c (md_undefined_symbol): use this for the local and
349 global register names; since there are hundreds of them, it
350 only defines them upon their first use.
351 * expr.c (operand): Call symbol_find_or_make rather than
352 roll our own undefined symbols.
355 Miscellaneous changes:
357 * as.h (know): Make this useful if DEBUG defined.
359 * write.h: Support SPARC-like relocation throughout all
362 * read.c (read_a_source_file): Report the name of invalid
363 pseudo-ops. Don't double-report junk characters. Close the
364 input file, which gas never used to do.
365 (ignore_rest_of_line): Report junk chars in ascii if
367 (s_ignore): Ignore entire statement; used for 'listing
368 control' statements from ASM29K, e.g. .eject.
370 * read.c (s_lsym): Handle register equates too.
372 * read.c: Add most ASM29K pseudo-ops to the master table.
373 Not all are implemented yet.
375 * cond.c: New file, for functions implementing conditional
376 assembly pseudo-ops: .ifdef, .ifndef, .else, .endif, .ifseq,
377 .ifsne, .end. So far, they are just stubbed out.
379 * read.c (pobegin): Allow the machine dependent pseudo-op
380 table to override the generic one. Remove #ifdef SPARC
381 on .word, since it can now be overridden.
383 * expr.c (operand): Support radix-2 constants. Kill off
384 support for octals with digits '8' and '9'. Initial steps
385 toward more general support for local-labels.
387 * symbols.h (symbol_table_lookup): Remove macro, change all
388 occurrences (in read.c, expr.c, symbols.c) to symbol_find.
390 * read.h (is_end_of_line): Define for external use.
392 * i386.c (alloca): Use builtin_alloca or include or extern.
394 * Makefile: Add ALL and all: entries. Add asm29k entries.
395 Add cond.c and cond.o. Remove special handling for messages.o.
398 Thu Sep 27 13:43:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
400 * m68k.c (get_num) Fix so that 1:w is treated properly.
402 * Makefile Replace references to a.out.h with a.out.gnu.h
404 Tue Sep 25 15:50:36 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
406 * sparc.c (md_number_to_imm) Fix so that RELOC_32 locations contain
407 zero, so that it will work with some sparc loaders which don't assume
408 that the locations in question do. A xix line patch from Michael Bloom
409 (usc!srhqla!quad1!psivax!ttidca!mb@zaphod.mps.ohio-state.edu)
411 Mon Sep 24 11:43:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
413 * as.c #include <sys/types.h> if _POSIX_SOURCE defined. This because
414 <signal.h> uses pid_t that's defined in it.
416 * m68k.c reverse the sense of -l option, and allow :w and :l to
417 override the default size of AOFF indexes.
419 Also, allow -l to shorten branches to unknown labels from LONG to WORD.
421 Thu Sep 13 17:05:09 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
423 * vax.c (md_parse_option) Don't print a warning msg if given -J
425 Wed Sep 5 14:26:14 EDT 1990 Jay Fenlason
427 * expr.c (operand) Don't get garbaged high-order bits when given a
428 lot of leading zeroes.
430 Tue Sep 4 11:40:21 EDT 1990 Jay Fenlason
432 * read.c (pseudo_set) Compain if we're setting the symbol to the
433 difference of two symbols which are in different frags. (We can't
434 find out how far apart they are.)
436 Wed Aug 15 12:18:58 EDT 1990 Jay Fenlason
438 * m68k.c (m68k_ip_op) Dyke out the code that deals with parsing
439 :[wl] at the end of expressions since it is handled in get_num()
440 and this was putting the result in the wrong place anyway.
441 Corrected a couple of other references to ->isiz instead of con?->e_siz
443 Mon Aug 13 15:53:46 EDT 1990 Jay Fenlason
445 * read.c Handle .align specially on the sparc, or any other machine
446 where OTHER_ALIGN is defined. Added option and comments about it
449 Fri Aug 10 12:24:33 EDT 1990 Jay Fenlason
451 * m68k.c (get_num) Handle SEG_PASS1 expressions.
453 Mon Aug 6 16:32:29 EDT 1990 Jay Fenlason
455 * write.c (fixup_segment) Added two patches for the NS32k
456 and SEQUENT A six line patch from Ian Dall
457 (asgard!aegir!hugin!augean!sibyl!ian@munnari.oz.au)
459 Wed Aug 1 13:30:48 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
461 * m68k.c Include REGISTER_PREFIX ifdefs.
463 * write.c Include LOCAL_LABEL() and DOT_LABEL_PREFIX feature.
465 * vax.c (md_parse_option) Accept -H option.
467 * vms.c New version of case hasher, etc. These from Eric Youngdale
468 <YOUNGDALE@v6550c.nrl.navy.mil>
470 Fri Jul 20 13:39:02 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
472 * README Added README.APOLLO and README.COFF stuff
474 Wed Jul 18 16:29:22 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
476 * Makefile Added option for SEQUENT_COMPATABILITY
478 * ns32k.c Add configurable syntax feature from
479 ian@sibyl.eleceng.ua.oz@augean.ua.oz.au
480 and SEQUENT_COMPATABILITY
482 * ns32k-opcode.h Add configurable syntax feature.
484 Mon Jul 16 11:44:14 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
486 * write.c (relax_segment) On ns32k, add fragP->fr_pcrel_adjust to
488 (fixup_segment) On ns32k, don't subtract size from
489 add_number on pcrel external symbols.
491 * ns32k.c (md_relax_table) Use correct max displacements.
492 This is a six-line patch from ian@sibyl.eleceng.ua.oz.au
494 * ns32k.c (md_atof, convert_iif) Emit floating point numbers in
495 the correct byte order. A seven line patch from
496 ian@sibyl.eleceng.ua.oz.au
498 * ns32k.c (all over) Some lint fixes.
500 Mon Jul 9 13:17:00 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
502 * app.c (do_scrub_next_char) If a comment is #{whitespace}
503 don't treat the next line as comment also.
505 * m68k.c (...) Accept apc@(num:[wl]), etc.
507 * i386.c (md_assemble) Get bitfields correct when doing cross
508 assembly to 386. A two line patch from Michael Bloom.
509 (usc!srhqla!quad1!ttidca!mb@zaphod.mps.ohio-state.edu).
511 * README.APOLLO a new file with vasta@apollo's name, address
514 * make-gas.com Deleted references to gdb source files.
516 Fri Jul 6 14:34:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
518 * i386.c Ignore the .optim directive
520 * input-file.c Change from _IOLBF to _IOFBF in setbuffer emulation
523 Mon Jun 18 15:36:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
525 * sparc.c #ifdef DONTDEF s_sparc_align, since it isn't called from
528 Fri Jun 15 15:53:30 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
530 * vax.c (md_parse_option) make the code agree with the documentation
531 on the behaviour of the -d option.
533 Thu Jun 7 14:23:54 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
535 * atof-ieee.c (gen_to_words) Assemble 0r-0 correctly.

679 * messages.c New function: as_bad This is like as_warn, except
680 -W doesn't disable it, and calling it inhibits production of an
681 object file and causes a non-zero exit code.
683 Tue Feb 13 14:25:53 EST 1990 hack@wookumz
684 * Makefile Include G0 and LOADLIBES for Sequent Symmetry.
685 Based on a small patch from Johan Widen (jw@sics.se)

734 * expr.c Replace the generic_buffer hack with a more portable one */
736 * atof-generic.c (atof_generic) Ignore trailing zeroes after a decimal
737 point. For some reason trailing zeroes (but not trailing nonzeroes) were
738 causing loss of precision. I don't know why. . .

840 Many anonymous entries have been attributed to Jay Fenlason (hack).
842 Thu Aug 17 15:53:57 1989 Jay Fenlason (hack at apple-gunkies.ai.mit.edu)
844 * Makefile: Removed $< references that seem
845 to choke some versions of make.

848 large frags (larger than frags.chunk_size).
850 * app.c (do_scrub_next_char): Have it ignore any characters

883 Wed Aug 2 12:55:?? 1989 Jay Fenlason (hack at apple-gunkies.ai.mit.edu)
885 * sparc.c (comment_chars[]): Removed '|' because it was causing
886 problems. Probably not the best fix, since I suspect other
887 assemblers (68020) may get | in .stabs also, and the 68020 needs
888 the '|' comment character.

908 allow one to set a symbol to the difference of two other symbols.
910 * ns32k.c (convert_iif): Moved size_so_far+=size and size=0 inside
911 the check for a valid type.

989 for HP-UX from Chris Hanson (cph@kleph.ai.mit.edu).
991 * m68k-opcode.h: Reorder movem insns so gdb will see the ones using the
992 register list syntax first.
994 * symbols.c (colon): Give more useful error messages when something was
995 defined as a .comm and is now trying to be defined locally.
996 Also, redefining a symbol is a fatal, not a warning.
998 * m68k.c: Fixed a bug in using bignums as literal bit patterns for
999 floating-point numbers.
1001 (In version 1.31) Jay Fenlason (hack)

1137 * Fixed a bug wherein ".long X" became ".long 0" on the Sparc.
1139 * Fixed a bug which caused many "#APP" "#NO_APP" pairs to dump core.
1141 * Fixed calls to _doprnt to call _vfprintf #ifndef NO_VARARGS.
1145 * Merged HP-UX changes from Chris Hanson (cph@zurich.ai.mit.edu).
1147 * flonum-multip.c: Renamed to flonum-mult.c.
1149 * m-hpux.h: Created.
1151 * m68k.c (bcopy): Fixed.
1155 * struct-symbol.h: Renamed to struc-symbol.h.
1159 * vax.c: Added a quick fix for the offset of fixed-width branches not
1160 fitting in the field given.
1162 * gdb-lines.c, read.c: Added support for .gdline and .gdbline
1167 * read.c, atof-generic.c: Fixed bugs in reading in floating-point
1170 * m68k-opcode.h: Made "fmovep a0@, fp0" work.
1174 * write.c: Fixed an obscure bug in relaction that would occasionally
1175 cause the assembler to stop relaxing when it really had at least one
1180 * m68k*: Allow register lists in fmovem.
1182 * Added more floating-point exponents.
1184 * Print an error message on exponent overflow.
1188 * Fixed floating point bugs that made it generate incorrect numbers for
1189 values over 10^16 or so.
1193 * Fixed bug wherein you couldn't forward reference local label 0.
1197 * m68k.c, m68k-opcode.h: Added support for fmovem with register lists.
1199 * Fixed an obscure bug having to do with generating PC-relative
1200 addressing mode for things in the middle of the instruction instead of

1216 * Added patches from pace to files as.h i386.c i386-opcode.h
1217 imull foo,%eax no longer gets assembled into the 32-64 bit
1218 multiply, which clobbers %edx behind gcc's back
1220 jcxz/jecxz were backwards
1222 There was a bug when using %ebp as a base register with no
1225 Instructions like andb $0xffffff, %al used to put out too many
1228 The splitting jump instructions across frags could happen when
1229 obstack_room()==6 too.
