1 Thu Nov 28 13:21:41 1991 Steve Chamberlain (sac at rtl.cygnus.com)
3 * config/obj-coff-bfd: made multiple sections with subsections
7 Mon Nov 25 17:26:22 1991 Steve Chamberlain (sac at cygnus.com)
9 * as.c: (perform_an_assembly_pass): moved declaration of i to
10 avoid a syntax error. Now always create the three default
11 sections when in MANY_SEGMENTS mode.
12 * as.h: New improved way of specifying MANY_SEGMENTS
13 * configure.in: hds object format is now coff-bfd
14 * subsegs.h: add line numbers and section stuff to the
15 segment_info structure. (But go back later and fix.. this is
19 Thu Oct 24 17:25:59 1991 Steve Chamberlain (steve at rtl.cygnus.com)
21 * config/obj-coff.c (obj_coff_dim): Allows newline to end a
24 Mon Oct 21 09:25:33 1991 Steve Chamberlain (steve at rtl.cygnus.com)
26 * configure.in: added ebmon entry.
27 * output-file.c (output_file_create, output_file_close) added
29 * write.c: more bfd support
30 * config/obj-coff.c config/obj-coff.h use bfd for swapping
32 * tc-a29k: added the reloc types we support now
35 Mon Oct 14 11:44:03 1991 Roland H. Pesch (pesch at cygnus.com)
37 * doc/Makefile (as.ms): one more sed workaround for texi2roff
38 (as.mm, as.me): new targets
40 Fri Oct 11 18:18:37 1991 Roland H. Pesch (pesch at cygnus.com)
42 * doc/Makefile: new targets as.info, as.ms
43 doc/as.texinfo: minor changes for texi2roff-2
44 Makefile.in: revise 'doc' target.
46 Fri Jan 4 12:48:22 EST 1991 Jay Fenlason (hack@ai.mit.edu)
48 * messages.c Moved as_perror from input-scrub.c Modified the
49 error messages to look better.
51 * output-file.c Don't call as_fatal, just call exit()
53 expr.c Slightly improve checking for foo-foo case in
54 clean_up_expression(). Detect foo: bar: ... foo-bar...
56 Tue Dec 4 16:29:20 EST 1990 Jay Fenlason (hack@ai.mit.edu)
58 * m68k.c Fixed an obscure bug involving AOFF mode with a
59 large constant displacement (Was forgetting to output the
62 make-gas.com Added a three line patch from Eric Youngdale that
63 makes it possible to submit make-gas.com to a batch queue.
65 Wed Nov 21 15:07:51 EST 1990 Jay Fenlason (hack@ai.mit.edu)
67 * vms.c (VMS_TBT_Routine_END) Add a four line patch from
70 Tue Nov 13 14:02:15 EST 1990 Jay Fenlason (hack@ai.mti.edu)
72 * vms-dbg.c (VMS_DBG_record()) Another one character patch from
75 Mon Oct 29 15:49:21 EST 1990 Jay Fenlason (hack@ai.mit.edu)
77 * read.c Replace some as_warn calls with as_bad.
79 Fri Oct 26 15:21:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
81 * i386.c, i860.c, ns32k.c Add const changes.
83 Mon Oct 22 14:04:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
85 * sparc.c Add const changes.
87 * make-gas.com define const= for VMS, since many older versions of
88 GCC don't work correctly with const under VMS.
90 Thu Oct 18 12:44:11 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
92 * i860.c i860-opcode.h Added patches from rgb@mcc.com
94 * read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
95 Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
96 patches, so debugging GCC output now works.
98 * hash.c (hash_grow) Remember to blank out the wall entry in the new
99 hash table. This is important on systems where malloc() returns
100 non-zero storage. . .
102 Tue Oct 16 10:11:35 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
104 * output-file.c (output_file_create) if output filename is given as
105 '-', write to stdout.
107 * m68k.c Finally get the PCREL code to work right. Add relaxation of
108 PCREL stuff This small fix from Ken Woodland
109 (kenny%datacube.uucp@uunet.uu.net).
111 * m68k.c Added some const declarations to constants. (md_relax_table,
112 md_pseudo_table, etc. . .)
114 Thu Oct 11 11:15:10 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
116 * Makefile, read.c, write.c Include the i860 port.
117 (New files i860.c i860-opcode.h i860.h)
119 * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
122 * (all over) Raeburn's const hacking. This reduces the data-space size by
123 declaring many tables, etc, as 'const'.
125 Mon Oct 22 22:48:22 1990 John Gilmore (gnu at cygint)
127 Make gas work if you turn on the know() checks.
129 * app.c: Only pass a single space through: the one after
130 the opcode. All other whitespace is removed, to match the
131 expectations of the parser in read.c.
133 * as.h: Remove obsolete comments. Remove JF's NDEBUG so
134 that know() can really work if you turn it on. Make
135 SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
137 * expr.c (operand): Change BITS_PER_INT to 8*sizeof(int).
139 * input-scrub.c: strlen("\0") doesn't return 1...
140 (as_where): Add space after line number in errors, like gcc.
142 * m68k.c (s_bss): Fake .bss into data section 255.
143 We can't cope with a real "BSS section" yet, but we can at
144 least do the right thing less efficiently (with lots of
147 * read.c: Turn lots of as_warn()'s into as_bad()'s.
149 * read.h (SKIP_WHITESPACE): Replace last instance of ASSERT()
152 * sparc.c (s_seg): We can't put frags into the BSS segment
153 yet, so just fake bss seg as 255th data segment.
155 * vax.c: Remove \'s from continued macro *parameters*. These
156 must have been added after the last time someone turned on
159 * write.c (relax_segment): Refine what we know() about the
160 symbols referenced during relaxation.
162 * Makefile (OTHER_ALIGN): Remove, handled in tables now.
163 Flip options a bit. These options really ought to go
166 Sun Oct 21 03:57:21 1990 John Gilmore (gnu at cygint)
170 * expr.c, write.c: Missing semicolon after know().
172 * write.c (fixup_segment): Allow pc-relative accesses to undefined
173 external symbols. Previously this would turn off pc-rel calc
174 of displacement, while leaving pc-rel opcode alone, botching.
176 * m68k.c (m68k_ip): Allow pc-relative effective addresses
177 for source operands. "pea" instructions are a good example
178 where we can shorten from abs long to pc+16bit.
179 (md_convert_frag): Fix "JBSR" comments to refer to "JSR", the
180 actual instruction. Insert comments about bug in 68000 bcc
181 and dbcc long code (that doesn't get exercised much). Add
182 comments about long pcrel displacements for -pic. Remove
183 "this code has not been tested" comment.
184 (md_estimate_size_before_relax): Now that fixup_segment
185 doesn't shortcircuit pc-relative fixups for undefined symbols,
186 only output them if -pic; else turn them absolute, which is
187 slightly faster. More JBSR->JSR comments.
188 (md_parse_options): Parse -pic.
190 Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint)
192 * Make sparc assembler more compatible with Sun assembler.
193 sparc.c: reformat pseudo-op table to match main table.
194 (md_assemble): Add SPECIAL_CASE_FDIV to assemble FDIV*
195 instructions as fdiv followed by fmovs to get around chip bug.
196 (s_common, s_seg): Accept "bss" section name.
197 (md_assemble): Handle "set" instructions with absolute
198 operands, that only take one instruction rather than two.
199 sparc-opcode.h (fdiv*): Mark instructions "S"pecial.
200 subsegs.c (subseg_change): Move tail pointer too.
201 symbols.c (colon): Allow new definitions to override .comm symbols,
202 as in VMS. Sun CC depends on this.
203 write.c (new_fix): Always take r_type argument, not just on sparc.
204 Chain fixP's in order, using tail pointer, so relocation
205 records come out in forward order like Sun as. Remove SPARC
207 write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
209 * am29k.c: Use s_align_bytes rather than a local copy.
211 * read.c (s_align): Rather than ifdef it, make two functions,
212 s_align_bytes and s_align_ptwo. Individual pseudo-op tables
213 can call whichever one they like.
215 * write.c (append): Move from append.c to here.
216 append.c: Remove file.
218 * Makefile (MDSRC, mdsrc): Easy way to edit all md.c's.
219 Fix options. Add option for -DDEBUG for know() and assert().
220 Remove append.c, am29k.h. Don't build special read-sparc.o.
221 Remove sparc.h. "make clean" removes am29k .o's. Add
222 dependencies on reloc.h.
224 Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint)
226 * Generalize sparc extensions to relocation info. Gas now
227 keeps relocation information internally in a different format
228 than how it is stored in the resulting .o. md_ri_to_bytes()
229 converts to external format. md_reloc_size says how large
230 each relocation record is in external format.
231 sparc.h: Remove this file. Rename to reloc.h. Rename struct
232 to reloc_info_generic.
233 reloc.h: Add relocation types for AMD 29000.
234 read.c, write.c: Always call fix_new with reloc-type argument.
235 write.c (emit_relocations): Make md_ri_to_bytes write directly
236 to output area rather than overwriting its argument then
238 md.h: Declare md_reloc_size and md_ri_to_bytes.
239 i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
240 (md_reloc_size): Specify correct value.
241 (md_ri_to_bytes): Convert format from internal to external.
243 write.c (write_object_file): Call md_section_align() which
244 rounds section sizes up if desired.
245 sparc.c (md_section_align): Round to 8 byte boundary.
246 i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align): Nop.
248 Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint)
250 Changes in support of the AMD 29000 version of gas.
252 * am29k-opcode.h: Add dummy entry to end so we can examine
253 item N+1 without exceeding table.
255 * am29k.h: New include file, derived from sparc.h. Kludged
256 together, still needs major work to get relocation working.
258 * am29k.c: New file, derived from sparc.c.
259 Put 29k-specific ASM29K pseudo-ops into table.
260 Change comment_chars to ASM29K.
261 Change s_seg to s_use.
262 Change s_sparc_align to s_29k_align, default operand to 4.
263 (define_some_regs): Define special register names.
264 (md_begin): Preprocess opcode table to mash together all
265 the variants of single opcodes. This simplifies later handling.
266 Call define_some_regs to preset special reg names.
267 (parse_operand): Add, parses out an operand from a stmt.
268 (machine_ip): Simplify, since 29K is simpler asm language.
269 Handle the various keyletters in the opcode table.
272 Handle include files in the assembler, with a .include
274 * as.h (input_scrub_include_file): declare.
275 * as.c (perform_an_assembly_pass): Avoid buffer hacking.
276 Start us off in text segment.
277 * read.c (read_a_source_file): Take a name as argument,
278 internalize all buffer handling. Don't start a new text
279 subsegment on each entry. Actually use the start and end
280 pointers returned by input_scrub_next_buffer.
281 (s_include): Call input_scrub_include_file for .include.
282 * input-scrub.c: Fix comments.
283 (struct input_save): Add, for saving state at .include.
284 (input_scrub_push, input_scrub_pop): Add, push & pop state.
285 (input_scrub_begin): Initialize next_saved_file.
286 (input_scrub_end): Free buffer.
287 (input_scrub_include_file): Add, to include a file.
288 (input_scrub_close): Add, to close a file.
289 (input_scrub_next_buffer): Set buffer-start address for
290 caller. If we hit EOF and were included, pop to previous file.
291 * input-file.c: Remove old includes. Remove old file-descriptor
292 hacking code, that was commented out.
293 (struct saved_file): Add, for saving state at .include.
294 (input_file_push, input_file_pop): Add, push & pop state.
295 (input_file_open): Don't buffer all files in one place.
296 (input_file_close): Add, close input file.
297 * input-file.h: Declare new functions.
298 * app.c: (struct app_save): Add, for saving state at .include.
299 (app_push, app_pop): Add, push and pop state.
300 (do_scrub_next_char): Move its static state variables out so
301 they can be saved and restored.
304 * app.c: Allow overriding of character meanings by machine
305 dependent strings. Avoid wiring character constants into app.c.
306 (do_scrub_begin): New meanings override old ones, not "OR" them.
307 Only handle /* comments if / is not already in use.
308 (do_scrub_next_char): Reorganize mass of nested if's
309 into a switch for speed. Don't assume ';' is line terminator.
310 Reorganize switch on characters, into a switch on their (machine-
311 dependent) lexer table meanings.
314 Encapsulate knowledge of segment types in fewer places.
315 This allows us to add the "SEG_REGISTER" type, as well as
316 providing flexibility for eventual COFF/ELF support.
317 * struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
318 set_symbol_segment, set_symbol_segment_keep_ext,
319 segment_name): Define macros to encapsulate this info.
320 * as.h: Remove externs for seg_name, seg_N_TYPE, N_TYPE_seg.
321 * symbols.c (symbol_new): Change 'type' arg to 'seg'.
322 * expr.c, i386.c, m68k.c, ns32k.c, read.c, symbols.c, vax.c,
324 * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of
325 md_estimate_size_before_relax.
326 * expr.c, read.c: Change 'type' arg to symbol_new.
327 * read.c, symbols.c, vax.c, write.c: Move md.h to end of includes.
330 Allow expressions to evaluate to registers.
331 * as.h: Add SEG_REGISTER.
332 * struc-symbol.h: Add fake N_REGISTER type.
333 * subseg.c: Add types to tables.
334 * expr.c (operand): Symbols of SEG_REGISTER type are
335 immediately evaluated like those of SEG_ABSOLUTE.
336 (clean_up_expression): Clean up SEG_REGISTER exprs.
339 Allow machine descriptions to cleanly extend the set of
341 * expr.c (operand): Call md_operand before rejecting an
342 operand as unacceptable.
344 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
345 * am29k.c (md_operand): Use this for %% and & prefix operators.
348 Allow machine descriptions to cleanly permit symbols to be
349 predefined upon first usage.
350 * symbols.c (symbol_find_or_make): Call md_undefined_symbol
351 before making an undefined symbol.
353 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
354 * am29k.c (md_undefined_symbol): use this for the local and
355 global register names; since there are hundreds of them, it
356 only defines them upon their first use.
357 * expr.c (operand): Call symbol_find_or_make rather than
358 roll our own undefined symbols.
361 Miscellaneous changes:
363 * as.h (know): Make this useful if DEBUG defined.
365 * write.h: Support SPARC-like relocation throughout all
368 * read.c (read_a_source_file): Report the name of invalid
369 pseudo-ops. Don't double-report junk characters. Close the
370 input file, which gas never used to do.
371 (ignore_rest_of_line): Report junk chars in ascii if
373 (s_ignore): Ignore entire statement; used for 'listing
374 control' statements from ASM29K, e.g. .eject.
376 * read.c (s_lsym): Handle register equates too.
378 * read.c: Add most ASM29K pseudo-ops to the master table.
379 Not all are implemented yet.
381 * cond.c: New file, for functions implementing conditional
382 assembly pseudo-ops: .ifdef, .ifndef, .else, .endif, .ifseq,
383 .ifsne, .end. So far, they are just stubbed out.
385 * read.c (pobegin): Allow the machine dependent pseudo-op
386 table to override the generic one. Remove #ifdef SPARC
387 on .word, since it can now be overridden.
389 * expr.c (operand): Support radix-2 constants. Kill off
390 support for octals with digits '8' and '9'. Initial steps
391 toward more general support for local-labels.
393 * symbols.h (symbol_table_lookup): Remove macro, change all
394 occurrences (in read.c, expr.c, symbols.c) to symbol_find.
396 * read.h (is_end_of_line): Define for external use.
398 * i386.c (alloca): Use builtin_alloca or include or extern.
400 * Makefile: Add ALL and all: entries. Add asm29k entries.
401 Add cond.c and cond.o. Remove special handling for messages.o.
404 Thu Sep 27 13:43:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
406 * m68k.c (get_num) Fix so that 1:w is treated properly.
408 * Makefile Replace references to a.out.h with a.out.gnu.h
410 Tue Sep 25 15:50:36 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
412 * sparc.c (md_number_to_imm) Fix so that RELOC_32 locations contain
413 zero, so that it will work with some sparc loaders which don't assume
414 that the locations in question do. A xix line patch from Michael Bloom
415 (usc!srhqla!quad1!psivax!ttidca!mb@zaphod.mps.ohio-state.edu)
417 Mon Sep 24 11:43:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
419 * as.c #include <sys/types.h> if _POSIX_SOURCE defined. This because
420 <signal.h> uses pid_t that's defined in it.
422 * m68k.c reverse the sense of -l option, and allow :w and :l to
423 override the default size of AOFF indexes.
425 Also, allow -l to shorten branches to unknown labels from LONG to WORD.
427 Thu Sep 13 17:05:09 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
429 * vax.c (md_parse_option) Don't print a warning msg if given -J
431 Wed Sep 5 14:26:14 EDT 1990 Jay Fenlason
433 * expr.c (operand) Don't get garbaged high-order bits when given a
434 lot of leading zeroes.
436 Tue Sep 4 11:40:21 EDT 1990 Jay Fenlason
438 * read.c (pseudo_set) Compain if we're setting the symbol to the
439 difference of two symbols which are in different frags. (We can't
440 find out how far apart they are.)
442 Wed Aug 15 12:18:58 EDT 1990 Jay Fenlason
444 * m68k.c (m68k_ip_op) Dyke out the code that deals with parsing
445 :[wl] at the end of expressions since it is handled in get_num()
446 and this was putting the result in the wrong place anyway.
447 Corrected a couple of other references to ->isiz instead of con?->e_siz
449 Mon Aug 13 15:53:46 EDT 1990 Jay Fenlason
451 * read.c Handle .align specially on the sparc, or any other machine
452 where OTHER_ALIGN is defined. Added option and comments about it
455 Fri Aug 10 12:24:33 EDT 1990 Jay Fenlason
457 * m68k.c (get_num) Handle SEG_PASS1 expressions.
459 Mon Aug 6 16:32:29 EDT 1990 Jay Fenlason
461 * write.c (fixup_segment) Added two patches for the NS32k
462 and SEQUENT A six line patch from Ian Dall
463 (asgard!aegir!hugin!augean!sibyl!ian@munnari.oz.au)
465 Wed Aug 1 13:30:48 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
467 * m68k.c Include REGISTER_PREFIX ifdefs.
469 * write.c Include LOCAL_LABEL() and DOT_LABEL_PREFIX feature.
471 * vax.c (md_parse_option) Accept -H option.
473 * vms.c New version of case hasher, etc. These from Eric Youngdale
474 <YOUNGDALE@v6550c.nrl.navy.mil>
476 Fri Jul 20 13:39:02 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
478 * README Added README.APOLLO and README.COFF stuff
480 Wed Jul 18 16:29:22 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
482 * Makefile Added option for SEQUENT_COMPATABILITY
484 * ns32k.c Add configurable syntax feature from
485 ian@sibyl.eleceng.ua.oz@augean.ua.oz.au
486 and SEQUENT_COMPATABILITY
488 * ns32k-opcode.h Add configurable syntax feature.
490 Mon Jul 16 11:44:14 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
492 * write.c (relax_segment) On ns32k, add fragP->fr_pcrel_adjust to
494 (fixup_segment) On ns32k, don't subtract size from
495 add_number on pcrel external symbols.
497 * ns32k.c (md_relax_table) Use correct max displacements.
498 This is a six-line patch from ian@sibyl.eleceng.ua.oz.au
500 * ns32k.c (md_atof, convert_iif) Emit floating point numbers in
501 the correct byte order. A seven line patch from
502 ian@sibyl.eleceng.ua.oz.au
504 * ns32k.c (all over) Some lint fixes.
506 Mon Jul 9 13:17:00 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
508 * app.c (do_scrub_next_char) If a comment is #{whitespace}
509 don't treat the next line as comment also.
511 * m68k.c (...) Accept apc@(num:[wl]), etc.
513 * i386.c (md_assemble) Get bitfields correct when doing cross
514 assembly to 386. A two line patch from Michael Bloom.
515 (usc!srhqla!quad1!ttidca!mb@zaphod.mps.ohio-state.edu).
517 * README.APOLLO a new file with vasta@apollo's name, address
520 * make-gas.com Deleted references to gdb source files.
522 Fri Jul 6 14:34:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
524 * i386.c Ignore the .optim directive
526 * input-file.c Change from _IOLBF to _IOFBF in setbuffer emulation
529 Mon Jun 18 15:36:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
531 * sparc.c #ifdef DONTDEF s_sparc_align, since it isn't called from
534 Fri Jun 15 15:53:30 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
536 * vax.c (md_parse_option) make the code agree with the documentation

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

740 * expr.c Replace the generic_buffer hack with a more portable one */
742 * atof-generic.c (atof_generic) Ignore trailing zeroes after a decimal
743 point. For some reason trailing zeroes (but not trailing nonzeroes) were
744 causing loss of precision. I don't know why. . .
746 * vms.c Change copyright notice. Install changes from Kenneth Adelman
747 (adelman@tgv.com) for c++? (A dozen lines or so)

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

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

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

914 allow one to set a symbol to the difference of two other symbols.
916 * ns32k.c (convert_iif): Moved size_so_far+=size and size=0 inside
917 the check for a valid type.
919 * sparc-opcode.h: Modified the entries for std "q,[1+i]", "D,[1+i]",

995 for HP-UX from Chris Hanson (cph@kleph.ai.mit.edu).
997 * m68k-opcode.h: Reorder movem insns so gdb will see the ones using the
998 register list syntax first.
1000 * symbols.c (colon): Give more useful error messages when something was
1001 defined as a .comm and is now trying to be defined locally.
1002 Also, redefining a symbol is a fatal, not a warning.
1004 * m68k.c: Fixed a bug in using bignums as literal bit patterns for
1005 floating-point numbers.
1007 (In version 1.31) Jay Fenlason (hack)

1044 * Made ". = X" and ".set .,X" equivalent to ".org X".

1046 currently assembling to.
1048 (In version 1.27) Jay Fenlason (hack)

1132 * Re-fixed _vfprintf stuff (?).
1134 * Made "movem REG, ADDR" work.
1136 * Improved preprocessing, without temporary files.
1140 * Don't produce an undefined empty symbol for ".globl foo," (a line
1141 ending with a comma).
1143 * Fixed a bug wherein ".long X" became ".long 0" on the Sparc.
1145 * Fixed a bug which caused many "#APP" "#NO_APP" pairs to dump core.
1147 * Fixed calls to _doprnt to call _vfprintf #ifndef NO_VARARGS.
1151 * Merged HP-UX changes from Chris Hanson (cph@zurich.ai.mit.edu).
1153 * flonum-multip.c: Renamed to flonum-mult.c.
1155 * m-hpux.h: Created.
1157 * m68k.c (bcopy): Fixed.
1161 * struct-symbol.h: Renamed to struc-symbol.h.
1165 * vax.c: Added a quick fix for the offset of fixed-width branches not
1166 fitting in the field given.
1168 * gdb-lines.c, read.c: Added support for .gdline and .gdbline
1173 * read.c, atof-generic.c: Fixed bugs in reading in floating-point
1176 * m68k-opcode.h: Made "fmovep a0@, fp0" work.
1180 * write.c: Fixed an obscure bug in relaction that would occasionally
1181 cause the assembler to stop relaxing when it really had at least one
1186 * m68k*: Allow register lists in fmovem.
1188 * Added more floating-point exponents.
1190 * Print an error message on exponent overflow.
1194 * Fixed floating point bugs that made it generate incorrect numbers for
1195 values over 10^16 or so.
1199 * Fixed bug wherein you couldn't forward reference local label 0.
1203 * m68k.c, m68k-opcode.h: Added support for fmovem with register lists.
1205 * Fixed an obscure bug having to do with generating PC-relative
1206 addressing mode for things in the middle of the instruction instead of

1211 * *.*: Modified copyright notices to reflect new General Public
1214 * Makefile: Added copyright notice.
1216 Fri Feb 17 09:42:01 1989 Jay Fenlason (hack at spiff)
1218 * Patched frags.c so that new frags start out bzero()ed.

1222 * Added patches from pace to files as.h i386.c i386-opcode.h
1223 imull foo,%eax no longer gets assembled into the 32-64 bit
1224 multiply, which clobbers %edx behind gcc's back
1226 jcxz/jecxz were backwards
1228 There was a bug when using %ebp as a base register with no
1231 Instructions like andb $0xffffff, %al used to put out too many
1234 The splitting jump instructions across frags could happen when
1235 obstack_room()==6 too.
