9 | * messages.c Moved as_perror from input-scrub.c Modified the | |
10 | error messages to look better. | |
11 | ||
12 | * output-file.c Don't call as_fatal, just call exit() | |
13 | ||
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) | |
18 | ||
19 | * m68k.c Fixed an obscure bug involving AOFF mode with a | |
20 | large constant displacement (Was forgetting to output the | |
21 | extension word.) | |
22 | ||
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. | |
25 | ||
26 | Wed Nov 21 15:07:51 EST 1990 Jay Fenlason (hack@ai.mit.edu) | |
27 | ||
28 | * vms.c (VMS_TBT_Routine_END) Add a four line patch from | |
29 | Eric Youngdale. | |
30 | ||
31 | Tue Nov 13 14:02:15 EST 1990 Jay Fenlason (hack@ai.mti.edu) | |
32 | ||
33 | * vms-dbg.c (VMS_DBG_record()) Another one character patch from | |
34 | Eric Youngdale. | |
35 | ||
36 | Mon Oct 29 15:49:21 EST 1990 Jay Fenlason (hack@ai.mit.edu) | |
37 | ||
38 | * read.c Replace some as_warn calls with as_bad. | |
39 | ||
40 | Fri Oct 26 15:21:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
41 | ||
42 | * i386.c, i860.c, ns32k.c Add const changes. | |
43 | ||
44 | Mon Oct 22 14:04:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
45 | ||
46 | * sparc.c Add const changes. | |
47 | ||
48 | * make-gas.com define const= for VMS, since many older versions of | |
49 | GCC don't work correctly with const under VMS. | |
50 | ||
51 | Thu Oct 18 12:44:11 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
52 | ||
53 | * i860.c i860-opcode.h Added patches from rgb@mcc.com | |
54 | ||
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. | |
58 | ||
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 | |
61 | non-zero storage. . . | |
62 | ||
63 | Tue Oct 16 10:11:35 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
64 | ||
65 | * output-file.c (output_file_create) if output filename is given as | |
66 | '-', write to stdout. | |
67 | ||
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). | |
71 | ||
72 | * m68k.c Added some const declarations to constants. (md_relax_table, | |
73 | md_pseudo_table, etc. . .) | |
74 | ||
75 | Thu Oct 11 11:15:10 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
76 | ||
77 | * Makefile, read.c, write.c Include the i860 port. | |
78 | (New files i860.c i860-opcode.h i860.h) | |
79 | ||
80 | * m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in | |
81 | PC relative mode. | |
82 | ||
83 | * (all over) Raeburn's const hacking. This reduces the data-space size by | |
84 | declaring many tables, etc, as 'const'. | |
85 | ||
86 | Mon Oct 22 22:48:22 1990 John Gilmore (gnu at cygint) | |
87 | ||
88 | Make gas work if you turn on the know() checks. | |
89 | ||
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. | |
93 | ||
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. | |
97 | ||
98 | * expr.c (operand): Change BITS_PER_INT to 8*sizeof(int). | |
99 | ||
100 | * input-scrub.c: strlen("\0") doesn't return 1... | |
101 | (as_where): Add space after line number in errors, like gcc. | |
102 | ||
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 | |
106 | zeroes). | |
107 | ||
108 | * read.c: Turn lots of as_warn()'s into as_bad()'s. | |
109 | ||
110 | * read.h (SKIP_WHITESPACE): Replace last instance of ASSERT() | |
111 | with know(). | |
112 | ||
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. | |
115 | ||
116 | * vax.c: Remove \'s from continued macro *parameters*. These | |
117 | must have been added after the last time someone turned on | |
118 | know() checking... | |
119 | ||
120 | * write.c (relax_segment): Refine what we know() about the | |
121 | symbols referenced during relaxation. | |
122 | ||
123 | * Makefile (OTHER_ALIGN): Remove, handled in tables now. | |
124 | Flip options a bit. These options really ought to go | |
125 | elsewhere. | |
126 | ||
127 | Sun Oct 21 03:57:21 1990 John Gilmore (gnu at cygint) | |
128 | ||
129 | Sun-3 fixes. | |
130 | ||
131 | * expr.c, write.c: Missing semicolon after know(). | |
132 | ||
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. | |
136 | ||
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. | |
150 | ||
151 | Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint) | |
152 | ||
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 | |
167 | ifdefs. | |
168 | write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP. | |
169 | ||
170 | * am29k.c: Use s_align_bytes rather than a local copy. | |
171 | ||
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. | |
175 | ||
176 | * write.c (append): Move from append.c to here. | |
177 | append.c: Remove file. | |
178 | ||
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. | |
184 | ||
185 | Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint) | |
186 | ||
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 | |
198 | bcopying it. | |
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. | |
203 | ||
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. | |
208 | ||
209 | Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint) | |
210 | ||
211 | Changes in support of the AMD 29000 version of gas. | |
212 | ||
213 | * am29k-opcode.h: Add dummy entry to end so we can examine | |
214 | item N+1 without exceeding table. | |
215 | ||
216 | * am29k.h: New include file, derived from sparc.h. Kludged | |
217 | together, still needs major work to get relocation working. | |
218 | ||
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. | |
231 | ||
232 | ||
233 | Handle include files in the assembler, with a .include | |
234 | pseudo-op. | |
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. | |
263 | ||
264 | ||
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. | |
273 | ||
274 | ||
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, | |
284 | write.c: Use macros. | |
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. | |
289 | ||
290 | ||
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. | |
298 | ||
299 | ||
300 | Allow machine descriptions to cleanly extend the set of | |
301 | possible operands. | |
302 | * expr.c (operand): Call md_operand before rejecting an | |
303 | operand as unacceptable. | |
304 | * md.h: declare. | |
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. | |
307 | ||
308 | ||
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. | |
313 | * md.h: declare. | |
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. | |
320 | ||
321 | ||
322 | Miscellaneous changes: | |
323 | ||
324 | * as.h (know): Make this useful if DEBUG defined. | |
325 | ||
326 | * write.h: Support SPARC-like relocation throughout all | |
327 | versions. | |
328 | ||
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 | |
333 | printable. | |
334 | (s_ignore): Ignore entire statement; used for 'listing | |
335 | control' statements from ASM29K, e.g. .eject. | |
336 | ||
337 | * read.c (s_lsym): Handle register equates too. | |
338 | ||
339 | * read.c: Add most ASM29K pseudo-ops to the master table. | |
340 | Not all are implemented yet. | |
341 | ||
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. | |
345 | ||
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. | |
349 | ||
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. | |
353 | ||
354 | * symbols.h (symbol_table_lookup): Remove macro, change all | |
355 | occurrences (in read.c, expr.c, symbols.c) to symbol_find. | |
356 | ||
357 | * read.h (is_end_of_line): Define for external use. | |
358 | ||
359 | * i386.c (alloca): Use builtin_alloca or include or extern. | |
360 | ||
361 | * Makefile: Add ALL and all: entries. Add asm29k entries. | |
362 | Add cond.c and cond.o. Remove special handling for messages.o. | |
363 | Add lint entry. | |
364 | ||
365 | Thu Sep 27 13:43:49 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
366 | ||
367 | * m68k.c (get_num) Fix so that 1:w is treated properly. | |
368 | ||
369 | * Makefile Replace references to a.out.h with a.out.gnu.h | |
370 | ||
371 | Tue Sep 25 15:50:36 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
372 | ||
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) | |
377 | ||
378 | Mon Sep 24 11:43:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
379 | ||
380 | * as.c #include <sys/types.h> if _POSIX_SOURCE defined. This because | |
381 | <signal.h> uses pid_t that's defined in it. | |
382 | ||
383 | * m68k.c reverse the sense of -l option, and allow :w and :l to | |
384 | override the default size of AOFF indexes. | |
385 | ||
386 | Also, allow -l to shorten branches to unknown labels from LONG to WORD. | |
387 | ||
388 | Thu Sep 13 17:05:09 EDT 1990 Jay Fenlason (hack@ai.mit.edu) | |
389 | ||
390 | * vax.c (md_parse_option) Don't print a warning msg if given -J | |
391 | ||
392 | Wed Sep 5 14:26:14 EDT 1990 Jay Fenlason | |
393 | ||
394 | * expr.c (operand) Don't get garbaged high-order bits when given a | |
395 | lot of leading zeroes. | |
396 | ||
397 | Tue Sep 4 11:40:21 EDT 1990 Jay Fenlason | |
398 | ||
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.) | |
402 | ||

810 | ||
811 | * Makefile: Removed $< references that seem | |
812 | to choke some versions of make. | |
813 | ||
814 | * frags.c (frag_grow): Fixed to deal with requests for very | |
815 | large frags (larger than frags.chunk_size). | |
816 | ||
817 | * app.c (do_scrub_next_char): Have it ignore any characters | |
818 | after the filename in a # line "filename". | |
819 | ||
820 | * sparc.c (s_common): On an error, don't print out | |
821 | input_line_pointer past the end of the line where the error is. | |
822 | ||
823 | * atof-generic.c (atof_generic): Accept any case for | |
824 | inf and nan. | |
825 | ||
826 | * m68k.c (m68_ip): Don't use PC-relative mode for alterable | |
827 | addressing modes. | |
828 | ||
829 | Tue Aug 15 04:58:36 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) | |
830 | ||
831 | * sparc.c (md_begin): Rewrote this function to perform consistency | |
832 | checks with the new opcode table. | |
833 | ||
834 | Fri Aug 11 16:01:16 1989 Roland McGrath (roland at apple-gunkies.ai.mit.edu) | |
835 | ||
836 | * sparc-opcode.h (struct sparc_opcode): Replaced `mask' field with | |
837 | `lose'; removed `last' field. Updated all opcodes accordingly. | |
838 | Fixed several opcodes that generated the wrong instructions. | |
839 | sparc.c (md_begin, sparc_ip): Changed to use new struct sparc_opcode. | |
840 | ||
841 | Thu Aug 3 14:44:24 1989 Jay Fenlason (hack at apple-gunkies.ai.mit.edu) | |
842 | ||
843 | * Makefile (a32k): Use read- and write-ns32k.o | |
844 | * ns32k.c (encode_operand): Make sure pcrel_adjust starts out zeroed. | |
845 | * read.c (cons): Call fix_new_ns32k() if NS32K is defined. | |
846 | * write.c (write_object_file): Ditto. | |
847 | These so that .word sym-sym (etc) will produce values with | |
848 | the proper byte-order. | |
849 | ||
850 | Wed Aug 2 12:55:?? 1989 Jay Fenlason (hack at apple-gunkies.ai.mit.edu) | |
851 | ||
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. | |
856 | ||

900 | * sparc.c: Handle [expr+reg]. | |
901 | Don't call getExpression when looking for an immediate and getting | |
902 | something that starts with % and isn't %hi or %lo. | |

959 | register list syntax first. | |
960 | ||
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. | |

1193 | immediate bytes | |
1194 | ||
1195 | The splitting jump instructions across frags could happen when | |
