1 Fri Oct 11 18:18:37 1991 Roland H. Pesch (pesch at cygnus.com)
3 * doc/Makefile: new targets as.info, as.ms
4 doc/as.texinfo: minor changes for texi2roff-2
5 Makefile.in: revise 'doc' target.
7 Fri Jan 4 12:48:22 EST 1991 Jay Fenlason (hack@ai.mit.edu)
9 * messages.c Moved as_perror from input-scrub.c Modified the
10 error messages to look better.
12 * output-file.c Don't call as_fatal, just call exit()
14 expr.c Slightly improve checking for foo-foo case in
15 clean_up_expression(). Detect foo: bar: ... foo-bar...
17 Tue Dec 4 16:29:20 EST 1990 Jay Fenlason (hack@ai.mit.edu)
19 * m68k.c Fixed an obscure bug involving AOFF mode with a
20 large constant displacement (Was forgetting to output the
23 make-gas.com Added a three line patch from Eric Youngdale that
24 makes it possible to submit make-gas.com to a batch queue.
26 Wed Nov 21 15:07:51 EST 1990 Jay Fenlason (hack@ai.mit.edu)
28 * vms.c (VMS_TBT_Routine_END) Add a four line patch from
31 Tue Nov 13 14:02:15 EST 1990 Jay Fenlason (hack@ai.mti.edu)
33 * vms-dbg.c (VMS_DBG_record()) Another one character patch from
36 Mon Oct 29 15:49:21 EST 1990 Jay Fenlason (hack@ai.mit.edu)
38 * read.c Replace some as_warn calls with as_bad.
40 Fri Oct 26 15:21:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
42 * i386.c, i860.c, ns32k.c Add const changes.
44 Mon Oct 22 14:04:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
46 * sparc.c Add const changes.
48 * make-gas.com define const= for VMS, since many older versions of
49 GCC don't work correctly with const under VMS.
51 Thu Oct 18 12:44:11 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
53 * i860.c i860-opcode.h Added patches from rgb@mcc.com
55 * read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
56 Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
57 patches, so debugging GCC output now works.
59 * hash.c (hash_grow) Remember to blank out the wall entry in the new
60 hash table. This is important on systems where malloc() returns
63 Tue Oct 16 10:11:35 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
65 * output-file.c (output_file_create) if output filename is given as
68 * m68k.c Finally get the PCREL code to work right. Add relaxation of
69 PCREL stuff This small fix from Ken Woodland
70 (kenny%datacube.uucp@uunet.uu.net).
72 * m68k.c Added some const declarations to constants. (md_relax_table,
73 md_pseudo_table, etc. . .)
75 Thu Oct 11 11:15:10 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
77 * Makefile, read.c, write.c Include the i860 port.
78 (New files i860.c i860-opcode.h i860.h)
80 * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
83 * (all over) Raeburn's const hacking. This reduces the data-space size by
84 declaring many tables, etc, as 'const'.
86 Mon Oct 22 22:48:22 1990 John Gilmore (gnu at cygint)
88 Make gas work if you turn on the know() checks.
90 * app.c: Only pass a single space through: the one after
91 the opcode. All other whitespace is removed, to match the
92 expectations of the parser in read.c.
94 * as.h: Remove obsolete comments. Remove JF's NDEBUG so
95 that know() can really work if you turn it on. Make
96 SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
98 * expr.c (operand): Change BITS_PER_INT to 8*sizeof(int).
100 * input-scrub.c: strlen("\0") doesn't return 1...
101 (as_where): Add space after line number in errors, like gcc.
103 * m68k.c (s_bss): Fake .bss into data section 255.
104 We can't cope with a real "BSS section" yet, but we can at
105 least do the right thing less efficiently (with lots of
108 * read.c: Turn lots of as_warn()'s into as_bad()'s.
110 * read.h (SKIP_WHITESPACE): Replace last instance of ASSERT()
113 * sparc.c (s_seg): We can't put frags into the BSS segment
114 yet, so just fake bss seg as 255th data segment.
116 * vax.c: Remove \'s from continued macro *parameters*. These
117 must have been added after the last time someone turned on
120 * write.c (relax_segment): Refine what we know() about the
121 symbols referenced during relaxation.
123 * Makefile (OTHER_ALIGN): Remove, handled in tables now.
124 Flip options a bit. These options really ought to go
127 Sun Oct 21 03:57:21 1990 John Gilmore (gnu at cygint)
131 * expr.c, write.c: Missing semicolon after know().
133 * write.c (fixup_segment): Allow pc-relative accesses to undefined
134 external symbols. Previously this would turn off pc-rel calc
135 of displacement, while leaving pc-rel opcode alone, botching.
137 * m68k.c (m68k_ip): Allow pc-relative effective addresses
138 for source operands. "pea" instructions are a good example
139 where we can shorten from abs long to pc+16bit.
140 (md_convert_frag): Fix "JBSR" comments to refer to "JSR", the
141 actual instruction. Insert comments about bug in 68000 bcc
142 and dbcc long code (that doesn't get exercised much). Add
143 comments about long pcrel displacements for -pic. Remove
144 "this code has not been tested" comment.
145 (md_estimate_size_before_relax): Now that fixup_segment
146 doesn't shortcircuit pc-relative fixups for undefined symbols,
147 only output them if -pic; else turn them absolute, which is
148 slightly faster. More JBSR->JSR comments.
149 (md_parse_options): Parse -pic.
151 Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint)
153 * Make sparc assembler more compatible with Sun assembler.
154 sparc.c: reformat pseudo-op table to match main table.
155 (md_assemble): Add SPECIAL_CASE_FDIV to assemble FDIV*
156 instructions as fdiv followed by fmovs to get around chip bug.
157 (s_common, s_seg): Accept "bss" section name.
158 (md_assemble): Handle "set" instructions with absolute
159 operands, that only take one instruction rather than two.
160 sparc-opcode.h (fdiv*): Mark instructions "S"pecial.
161 subsegs.c (subseg_change): Move tail pointer too.
162 symbols.c (colon): Allow new definitions to override .comm symbols,
163 as in VMS. Sun CC depends on this.
164 write.c (new_fix): Always take r_type argument, not just on sparc.
165 Chain fixP's in order, using tail pointer, so relocation
166 records come out in forward order like Sun as. Remove SPARC
168 write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
170 * am29k.c: Use s_align_bytes rather than a local copy.
172 * read.c (s_align): Rather than ifdef it, make two functions,
173 s_align_bytes and s_align_ptwo. Individual pseudo-op tables
174 can call whichever one they like.
176 * write.c (append): Move from append.c to here.
177 append.c: Remove file.
179 * Makefile (MDSRC, mdsrc): Easy way to edit all md.c's.
180 Fix options. Add option for -DDEBUG for know() and assert().
181 Remove append.c, am29k.h. Don't build special read-sparc.o.
182 Remove sparc.h. "make clean" removes am29k .o's. Add
183 dependencies on reloc.h.
185 Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint)
187 * Generalize sparc extensions to relocation info. Gas now
188 keeps relocation information internally in a different format
189 than how it is stored in the resulting .o. md_ri_to_bytes()
190 converts to external format. md_reloc_size says how large
191 each relocation record is in external format.
192 sparc.h: Remove this file. Rename to reloc.h. Rename struct
193 to reloc_info_generic.
194 reloc.h: Add relocation types for AMD 29000.
195 read.c, write.c: Always call fix_new with reloc-type argument.
196 write.c (emit_relocations): Make md_ri_to_bytes write directly
197 to output area rather than overwriting its argument then
199 md.h: Declare md_reloc_size and md_ri_to_bytes.
200 i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
201 (md_reloc_size): Specify correct value.
202 (md_ri_to_bytes): Convert format from internal to external.
204 write.c (write_object_file): Call md_section_align() which
205 rounds section sizes up if desired.
206 sparc.c (md_section_align): Round to 8 byte boundary.
207 i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align): Nop.
209 Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint)
211 Changes in support of the AMD 29000 version of gas.
213 * am29k-opcode.h: Add dummy entry to end so we can examine
214 item N+1 without exceeding table.
216 * am29k.h: New include file, derived from sparc.h. Kludged
217 together, still needs major work to get relocation working.
219 * am29k.c: New file, derived from sparc.c.
220 Put 29k-specific ASM29K pseudo-ops into table.
221 Change comment_chars to ASM29K.
222 Change s_seg to s_use.
223 Change s_sparc_align to s_29k_align, default operand to 4.
224 (define_some_regs): Define special register names.
225 (md_begin): Preprocess opcode table to mash together all
226 the variants of single opcodes. This simplifies later handling.
227 Call define_some_regs to preset special reg names.
228 (parse_operand): Add, parses out an operand from a stmt.
229 (machine_ip): Simplify, since 29K is simpler asm language.
230 Handle the various keyletters in the opcode table.
233 Handle include files in the assembler, with a .include
235 * as.h (input_scrub_include_file): declare.
236 * as.c (perform_an_assembly_pass): Avoid buffer hacking.
237 Start us off in text segment.
238 * read.c (read_a_source_file): Take a name as argument,
239 internalize all buffer handling. Don't start a new text
240 subsegment on each entry. Actually use the start and end
241 pointers returned by input_scrub_next_buffer.
242 (s_include): Call input_scrub_include_file for .include.
243 * input-scrub.c: Fix comments.
244 (struct input_save): Add, for saving state at .include.
245 (input_scrub_push, input_scrub_pop): Add, push & pop state.
246 (input_scrub_begin): Initialize next_saved_file.
247 (input_scrub_end): Free buffer.
248 (input_scrub_include_file): Add, to include a file.
249 (input_scrub_close): Add, to close a file.
250 (input_scrub_next_buffer): Set buffer-start address for
251 caller. If we hit EOF and were included, pop to previous file.
252 * input-file.c: Remove old includes. Remove old file-descriptor
253 hacking code, that was commented out.
254 (struct saved_file): Add, for saving state at .include.
255 (input_file_push, input_file_pop): Add, push & pop state.
256 (input_file_open): Don't buffer all files in one place.
257 (input_file_close): Add, close input file.
258 * input-file.h: Declare new functions.
259 * app.c: (struct app_save): Add, for saving state at .include.
260 (app_push, app_pop): Add, push and pop state.
261 (do_scrub_next_char): Move its static state variables out so
262 they can be saved and restored.
265 * app.c: Allow overriding of character meanings by machine
266 dependent strings. Avoid wiring character constants into app.c.
267 (do_scrub_begin): New meanings override old ones, not "OR" them.
268 Only handle /* comments if / is not already in use.
269 (do_scrub_next_char): Reorganize mass of nested if's
270 into a switch for speed. Don't assume ';' is line terminator.
271 Reorganize switch on characters, into a switch on their (machine-
272 dependent) lexer table meanings.
275 Encapsulate knowledge of segment types in fewer places.
276 This allows us to add the "SEG_REGISTER" type, as well as
277 providing flexibility for eventual COFF/ELF support.
278 * struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
279 set_symbol_segment, set_symbol_segment_keep_ext,
280 segment_name): Define macros to encapsulate this info.
281 * as.h: Remove externs for seg_name, seg_N_TYPE, N_TYPE_seg.
282 * symbols.c (symbol_new): Change 'type' arg to 'seg'.
283 * expr.c, i386.c, m68k.c, ns32k.c, read.c, symbols.c, vax.c,
285 * i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of
286 md_estimate_size_before_relax.
287 * expr.c, read.c: Change 'type' arg to symbol_new.
288 * read.c, symbols.c, vax.c, write.c: Move md.h to end of includes.
291 Allow expressions to evaluate to registers.
292 * as.h: Add SEG_REGISTER.
293 * struc-symbol.h: Add fake N_REGISTER type.
294 * subseg.c: Add types to tables.
295 * expr.c (operand): Symbols of SEG_REGISTER type are
296 immediately evaluated like those of SEG_ABSOLUTE.
297 (clean_up_expression): Clean up SEG_REGISTER exprs.
300 Allow machine descriptions to cleanly extend the set of
302 * expr.c (operand): Call md_operand before rejecting an
303 operand as unacceptable.
305 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
306 * am29k.c (md_operand): Use this for %% and & prefix operators.
309 Allow machine descriptions to cleanly permit symbols to be
310 predefined upon first usage.
311 * symbols.c (symbol_find_or_make): Call md_undefined_symbol
312 before making an undefined symbol.
314 * i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
315 * am29k.c (md_undefined_symbol): use this for the local and
316 global register names; since there are hundreds of them, it
317 only defines them upon their first use.
318 * expr.c (operand): Call symbol_find_or_make rather than
319 roll our own undefined symbols.
322 Miscellaneous changes:
324 * as.h (know): Make this useful if DEBUG defined.
326 * write.h: Support SPARC-like relocation throughout all
329 * read.c (read_a_source_file): Report the name of invalid
330 pseudo-ops. Don't double-report junk characters. Close the
331 input file, which gas never used to do.
332 (ignore_rest_of_line): Report junk chars in ascii if
334 (s_ignore): Ignore entire statement; used for 'listing
335 control' statements from ASM29K, e.g. .eject.
337 * read.c (s_lsym): Handle register equates too.
339 * read.c: Add most ASM29K pseudo-ops to the master table.
340 Not all are implemented yet.
342 * cond.c: New file, for functions implementing conditional
343 assembly pseudo-ops: .ifdef, .ifndef, .else, .endif, .ifseq,
344 .ifsne, .end. So far, they are just stubbed out.
346 * read.c (pobegin): Allow the machine dependent pseudo-op
347 table to override the generic one. Remove #ifdef SPARC
348 on .word, since it can now be overridden.
350 * expr.c (operand): Support radix-2 constants. Kill off
351 support for octals with digits '8' and '9'. Initial steps
352 toward more general support for local-labels.
354 * symbols.h (symbol_table_lookup): Remove macro, change all
355 occurrences (in read.c, expr.c, symbols.c) to symbol_find.
357 * read.h (is_end_of_line): Define for external use.
359 * i386.c (alloca): Use builtin_alloca or include or extern.
361 * Makefile: Add ALL and all: entries. Add asm29k entries.
362 Add cond.c and cond.o. Remove special handling for messages.o.
365 Thu Sep 27 13:43:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
367 * m68k.c (get_num) Fix so that 1:w is treated properly.
369 * Makefile Replace references to a.out.h with a.out.gnu.h
371 Tue Sep 25 15:50:36 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
373 * sparc.c (md_number_to_imm) Fix so that RELOC_32 locations contain
374 zero, so that it will work with some sparc loaders which don't assume
375 that the locations in question do. A xix line patch from Michael Bloom
376 (usc!srhqla!quad1!psivax!ttidca!mb@zaphod.mps.ohio-state.edu)
378 Mon Sep 24 11:43:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
380 * as.c #include <sys/types.h> if _POSIX_SOURCE defined. This because
381 <signal.h> uses pid_t that's defined in it.
383 * m68k.c reverse the sense of -l option, and allow :w and :l to
384 override the default size of AOFF indexes.
386 Also, allow -l to shorten branches to unknown labels from LONG to WORD.
388 Thu Sep 13 17:05:09 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
390 * vax.c (md_parse_option) Don't print a warning msg if given -J
392 Wed Sep 5 14:26:14 EDT 1990 Jay Fenlason
394 * expr.c (operand) Don't get garbaged high-order bits when given a
395 lot of leading zeroes.
397 Tue Sep 4 11:40:21 EDT 1990 Jay Fenlason
399 * read.c (pseudo_set) Compain if we're setting the symbol to the
400 difference of two symbols which are in different frags. (We can't
401 find out how far apart they are.)
403 Wed Aug 15 12:18:58 EDT 1990 Jay Fenlason
405 * m68k.c (m68k_ip_op) Dyke out the code that deals with parsing
406 :[wl] at the end of expressions since it is handled in get_num()
407 and this was putting the result in the wrong place anyway.
408 Corrected a couple of other references to ->isiz instead of con?->e_siz
410 Mon Aug 13 15:53:46 EDT 1990 Jay Fenlason
412 * read.c Handle .align specially on the sparc, or any other machine
413 where OTHER_ALIGN is defined. Added option and comments about it
416 Fri Aug 10 12:24:33 EDT 1990 Jay Fenlason
418 * m68k.c (get_num) Handle SEG_PASS1 expressions.
420 Mon Aug 6 16:32:29 EDT 1990 Jay Fenlason
422 * write.c (fixup_segment) Added two patches for the NS32k
423 and SEQUENT A six line patch from Ian Dall
424 (asgard!aegir!hugin!augean!sibyl!ian@munnari.oz.au)

428 * m68k.c Include REGISTER_PREFIX ifdefs.
430 * write.c Include LOCAL_LABEL() and DOT_LABEL_PREFIX feature.
432 * vax.c (md_parse_option) Accept -H option.
434 * vms.c New version of case hasher, etc. These from Eric Youngdale
435 <YOUNGDALE@v6550c.nrl.navy.mil>
437 Fri Jul 20 13:39:02 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
439 * README Added README.APOLLO and README.COFF stuff
441 Wed Jul 18 16:29:22 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
443 * Makefile Added option for SEQUENT_COMPATABILITY
445 * ns32k.c Add configurable syntax feature from
446 ian@sibyl.eleceng.ua.oz@augean.ua.oz.au
447 and SEQUENT_COMPATABILITY
449 * ns32k-opcode.h Add configurable syntax feature.
451 Mon Jul 16 11:44:14 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
453 * write.c (relax_segment) On ns32k, add fragP->fr_pcrel_adjust to
455 (fixup_segment) On ns32k, don't subtract size from
456 add_number on pcrel external symbols.
458 * ns32k.c (md_relax_table) Use correct max displacements.
459 This is a six-line patch from ian@sibyl.eleceng.ua.oz.au
461 * ns32k.c (md_atof, convert_iif) Emit floating point numbers in
462 the correct byte order. A seven line patch from
463 ian@sibyl.eleceng.ua.oz.au
465 * ns32k.c (all over) Some lint fixes.
467 Mon Jul 9 13:17:00 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
469 * app.c (do_scrub_next_char) If a comment is #{whitespace}
470 don't treat the next line as comment also.
472 * m68k.c (...) Accept apc@(num:[wl]), etc.
474 * i386.c (md_assemble) Get bitfields correct when doing cross
475 assembly to 386. A two line patch from Michael Bloom.
476 (usc!srhqla!quad1!ttidca!mb@zaphod.mps.ohio-state.edu).
478 * README.APOLLO a new file with vasta@apollo's name, address
481 * make-gas.com Deleted references to gdb source files.

490 Mon Jun 18 15:36:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
492 * sparc.c #ifdef DONTDEF s_sparc_align, since it isn't called from
495 Fri Jun 15 15:53:30 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
497 * vax.c (md_parse_option) make the code agree with the documentation
498 on the behaviour of the -d option.
500 Thu Jun 7 14:23:54 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
502 * atof-ieee.c (gen_to_words) Assemble 0r-0 correctly.
504 * Makefile Remove last references to gdb*.c files.
506 * version.c New version 1.36
508 Tue May 22 13:22:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
510 * Makefile Mention a work-around for a possible problem with HPUX7.0
512 Mon May 21 14:06:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
514 * sparc.c (sparc_ip): Change error message from "not in hash table"
517 Wed May 16 15:33:14 EDT 1990 hack@wookumz
519 * i386.c (i386_operand) Print error msg if given an operand like
520 4(mumble) which we can't parse.
522 * m68k.c (md_assemble) Add '3' to the list of operand-places that
523 can be found in 'symbol-dependent info'. Also change
524 'confusing width' diagnostic to something more meaningful.
526 Fri May 11 12:09:21 EDT 1990 hack@wookumz
528 app.c (do_scrub_next_char) Don't flush the line after a line

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

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

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

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

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

959 register list syntax first.
961 * symbols.c (colon): Give more useful error messages when something was
962 defined as a .comm and is now trying to be defined locally.
963 Also, redefining a symbol is a fatal, not a warning.
965 * m68k.c: Fixed a bug in using bignums as literal bit patterns for
966 floating-point numbers.
968 (In version 1.31) Jay Fenlason (hack)
