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

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

527 A one line patch from Steve Bleazard (steve@robobar.co.uk
529 Tue May 8 12:56:25 EDT 1990 hack@wookumz
531 * atof-generic.c (atof-generic) Modified the Infinity detection code
532 to accept 0rinfinity and 0r-infinity as well as 0rinf and 0r-inf

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

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

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

846 * sparc.c (comment_chars[]): Removed '|' because it was causing
847 problems. Probably not the best fix, since I suspect other
848 assemblers (68020) may get | in .stabs also, and the 68020 needs
849 the '|' comment character.

871 * ns32k.c (convert_iif): Moved size_so_far+=size and size=0 inside
872 the check for a valid type.

957 Also, redefining a symbol is a fatal, not a warning.
