| 2 | |
| 3 | * obj-coff.c (obj_coff_endef): Use as_warn, not fprintf. |
| 4 | |
| 5 | * tc-m68k.c (md_assemble): Don't complain about 68000 with 68881; |
| 6 | could be doing emulation. |
| 7 | |
| 8 | Tue Nov 10 09:50:25 1992 Ian Lance Taylor (ian@cygnus.com) |
| 9 | |
| 10 | * tc-m68k.c (m68k_reg_parse): If REGISTER_PREFIX isn't defined, |
| 11 | still accept (but don't require) OPTIONAL_REGISTER_PREFIX before |
| 12 | the register name. |
| 13 | (insert_reg): put REGISTER_PREFIX before register names before |
| 14 | putting them in the symbol table. |
| 15 | * tc-m68k.h (OPTIONAL_REGISTER_PREFIX): Define to be "%", if not |
| 16 | M68KCOFF. |
| 17 | |
| 18 | * obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss |
| 19 | section. |
| 20 | |
| 21 | * atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS, |
| 22 | comment_chars, line_comment_chars and line_seperator_chars |
| 23 | consistently const, and always initialized them. Included read.h. |
| 24 | |
| 25 | Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com) |
| 26 | |
| 27 | * tc-sparc.c (sparc_ip): Add code to flag error if an absolute |
| 28 | constant will not fit in an immediate field. |

| 34 | (obj_emit_relocations): Define it locally here, and only if |
| 35 | TC_I960 is defined. |
| 36 | |
| 37 | * tc-m68k.c (m68k_reg_parse): Underscore is part of a symbol name. |
| 38 | (m68k_ip): Don't warn about bignum used as float bit-pattern. |
| 39 | |
| 40 | * obj-coff.c: Replaced ANSI and non-ANSI function declarations |
| 41 | with a single set using PARAMS macro. |
| 42 | |
| 43 | * tc-i960.c (tc_bout_fix_to_chars): Bit-field fixups want a length |
| 44 | of 2. |
| 45 | |
| 46 | * tc-i960.c: Missed a couple of 0->NO_RELOC conversions. |
| 47 | |
| 48 | * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values, |
| 49 | so widening works consistently. |
| 50 | |
| 51 | Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com) |
| 52 | |
| 53 | * obj-coffbfd.c (write_object_file): check return value of |

| 55 | |
| 56 | Tue Oct 20 13:02:25 1992 Ian Lance Taylor (ian@cygnus.com) |
| 57 | |
| 58 | * Support for i386-sysv. |
| 59 | obj-coffbfd.c (do_relocs_for, write_object_file): set segment |
| 60 | addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can |
| 61 | be used to set them all to zero as was done before. |
| 62 | (fill_section): segment addresses now set in write_object_file. |
| 63 | (fill_section): Don't set STYP_NOLOAD for .bss section. |
| 64 | (fixup_segment): 386 uses strange common symbol format. |
| 65 | tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for |
| 66 | compatibility with SVR3.2 linker. |
| 67 | |
| 68 | Mon Oct 5 09:28:57 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 69 | |

| 71 | * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line): |
| 72 | support for C source listings. (obj_coff_endef): look in the right |
| 73 | part of the symbol for the symbol name |
| 74 | |
| 75 | * tc-m68k.c (get_num): make it work for all segments, not just the |
| 76 | first three. |
| 77 | |
| 78 | Tue Sep 29 12:22:52 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 79 | |
| 80 | * obj-coffbfd.c (write_object_file): don't fixup for the z8k |
| 81 | * tc-z8k.c: lots of bug fixes |
| 82 | |
| 83 | Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com) |
| 84 | |
| 85 | * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition |
| 86 | #elif, since it is not supported by old compilers. |
| 87 | ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a |
| 88 | couple of expressions in tc-m68k.c. |
| 89 | |
| 90 | Mon Sep 28 21:16:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com) |
| 91 | |
| 92 | * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new. |
| 93 | |
| 94 | Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com) |
| 95 | |
| 96 | * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require |
| 97 | local labels to start with a .) and set REGISTER_PREFIX to %. |
| 98 | tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined. |
| 99 | |
| 100 | Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com) |
| 101 | |
| 102 | * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all |
| 103 | sections starting from zero, rather than making them consecutive. |
| 104 | This makes subsequent reloc calculations easier, esp if the object |
| 105 | format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily) |
| 106 | allocate lcomm in .data rather than in .bss. It seems that some |
| 107 | tools can't cope with a non-zero sized bss before linkage. |
| 108 | |
| 109 | Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com) |
| 110 | |
| 111 | * tc-m68k.c: Replace "enum m68k_architecture" with "int" |
| 112 | throughout. That enum no longer means what we thought it meant. |
| 113 | |
| 114 | * tc-m68k.c (md_assemble, md_parse_option): Handle new |
| 115 | "-mno-688[58]1" options. |
| 116 | |
| 117 | * tc-m68k.c: Added CPU32 support. |
| 118 | |
| 119 | Fri Sep 18 08:02:18 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 120 | |
| 121 | * tc-m68k.c (m68k_ip): An(disp) is not pc relative. |
| 122 | |
| 123 | Sun Sep 13 20:29:39 1992 Ian Lance Taylor (ian@cygnus.com) |
| 124 | |
| 125 | * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD. |
| 126 | obj-coffbfd.c (fixup_segment): check for signed .word overflow if |
| 127 | WARN_SIGNED_OVERFLOW_WORD. |
| 128 | |
| 129 | * obj-coffbfd.c (fixup_segment): fixed missing parens in |
| 130 | expression checking for byte or word overflow. |
| 131 | |
| 132 | Fri Sep 11 10:21:04 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 133 | |
| 134 | Support for i386 coff |
| 135 | * obj-coffbfd.h : added stuff |
| 136 | * tc-i386.c (tc_coff_fix2rtype): new function |
| 137 | * tc-i386.h : new coff defines |
| 138 | |
| 139 | Wed Sep 9 11:10:24 1992 Ian Lance Taylor (ian@cygnus.com) |
| 140 | |
| 141 | * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge |
| 142 | Motorola and MIT syntax; gas can now assemble either type of |
| 143 | file. |
| 144 | tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files. |
| 145 | From Steve Chamberlain: |
| 146 | m68kcoff.mt: for m68k COFF. |
| 147 | obj-coffbfd.c: (fixup_mdeps) added |
| 148 | (size_section) removed bad sanity check |
| 149 | (fill_section) added rs_machine_dependent case |
| 150 | (write_object_file) call fixup_mdeps |
| 151 | (fixup_segment) set fx_subsy to 0. |
| 152 | obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and |
| 153 | handle m68k. |
| 154 | tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala |
| 155 | pseudo ops. |
| 156 | |
| 157 | Fri Aug 28 16:25:22 1992 Ian Lance Taylor (ian@cygnus.com) |
| 158 | |
| 159 | * obj-bout.h, obj-bout.c (obj_header_append, obj_symbol_to_chars), |
| 160 | tc-i960.c (md_ri_to_chars): Always output bout object file in |
| 161 | little endian byte order (used to use endianness of host). |
| 162 | |
| 163 | Tue Aug 25 15:11:08 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 164 | |
| 165 | * z8k.c, z8k.h, z8k.mt: z8000 support stuff |
| 166 | |
| 167 | Mon Aug 24 12:45:12 1992 Ian Lance Taylor (ian@cygnus.com) |
| 168 | |
| 169 | * tc-m68k.c: use TARGET_CPU to choose default cpu type. |
| 170 | |
| 171 | * te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB |
| 172 | so that we can assemble hand-written libgcc code. |
| 173 | |
| 174 | Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com) |
| 175 | |
| 176 | * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be |
| 177 | written with indirection on the last two operands, which can be |
| 178 | either data or address registers. Added a new operand type 'r' |
| 179 | which accepts either register type. Added '(' to notend stuff in |
| 180 | tc-m68kmote.c to accept (a0):(a2) in cas2 instruction. |
| 181 | |
| 182 | Tue Aug 11 12:58:14 1992 Ken Raeburn (raeburn@cygnus.com) |
| 183 | |

| 186 | Mon Aug 10 14:37:08 1992 Per Bothner (bothner@cygnus.com) |
| 187 | |
| 188 | * tc-m68k.c: ".align N" means align to N-byte boundary *only* |
| 189 | if TN_SUN3; otherwise align to 2**N-byte bounary. |
| 190 | |
| 191 | Thu Aug 6 12:08:42 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 192 | |
| 193 | * config/tc-h8300.c: if a :8 is seen after an operand, fill top |
| 194 | two bytes of any constant with 0xff: |
| 195 | |
| 196 | Wed Aug 5 01:54:34 1992 John Gilmore (gnu at cygnus.com) |
| 197 | |
| 198 | * tc-m68k.c (try_index): Error if index scaling specified and |
| 199 | assembling for an older CPU than a 68020. |
| 200 | |
| 201 | Mon Jul 6 17:09:32 1992 Steve Chamberlain (sac@cygnus.com) |
| 202 | |
| 203 | * obj-coffbfd.c (fill_section): mark .lit sections as STYP_LIT |
| 204 | |
| 205 | Tue Jun 9 07:50:46 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 206 | |
| 207 | * tc-m68k.c (m68kip): Fix typo so that only arch's >=68020 do |
| 208 | pcrel data stuff. (md_estimate_size_before_relax): when relaxing a |
| 209 | 68010 bxx into a bra+6 jmpxx, put the bytes of the jmp opcode into |
| 210 | the right place. (s_bss): Don't put .bss stuff into SEG_DATA, put |
| 211 | it into SEG_BSS |
| 212 | |
| 213 | Thu May 28 11:20:27 1992 Jim Wilson (wilson@sphagnum.cygnus.com) |
| 214 | |
| 215 | * tc-sparc.c: Use new ARCHITECTURES_CONFLICT_P macro. Mention new |
| 216 | -Asparclite flag. |
| 217 | |
| 218 | Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com) |
| 219 | |
| 220 | * obj-coffbfd.c: use is a synonym for section, (do_relocs_for): |
| 221 | calc the base of relocs correctly. |
| 222 | * tc-a29k.c (parse_operand): allow expressions to be in any section. |
| 223 | |
| 224 | Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com) |
| 225 | |
| 226 | * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from |
| 227 | tc-m68k.h to te-sun3.h. |
| 228 | |
| 229 | Wed Mar 11 23:34:46 1992 K. Richard Pixley (rich@cygnus.com) |
| 230 | |
| 231 | * te-sun3.h: add LOCAL_LABELS_DOLLAR. |
| 232 | |
| 233 | Fri Feb 21 06:22:15 1992 K. Richard Pixley (rich@rtl.cygnus.com) |
| 234 | |
| 235 | * obj-aout.c: do not include stab.gnu.h if NO_LISTING. |
| 236 | |
| 237 | * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place. |
| 238 | |
| 239 | * a.out.h: removed. |
| 240 | |
| 241 | Fri Feb 21 02:17:22 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM) |
| 242 | |
| 243 | * tc-i386.c: tc-i386.c: added handling of the following opcodes: |
| 244 | i/o opcodes - inb, inw, outb and outw. string manipulation with |
| 245 | att syntax - scmp, slod, smov, ssca, ssto. |
| 246 | |
| 247 | Fri Feb 21 01:53:50 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM) |
| 248 | |
| 249 | * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss |
| 250 | to just after .file . |
| 251 | |
| 252 | In obj_crawl_symbol_chain() where it tries to put the external |
| 253 | symbols apart, with the condition: |
| 254 | (!S_IS_DEFINED(symbolP) && |
| 255 | !S_IS_DEBUG(symbolP) && |
| 256 | !SF_GET_STATICS(symbolP)) |
| 257 | it was moving too many symbols out. So I switch it back to the |
| 258 | condition: |
| 259 | (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP)) |
| 260 | |
| 261 | In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO |
| 262 | so that we don't use the F_RELFLG which make the linker complain |
| 263 | that somebody has stripped the relocation info. |
| 264 | |
| 265 | Also, the AIX ld program require that the relocation table |
| 266 | is sorted by r_vaddr like the standard ATT assembler does. |
| 267 | |
| 268 | [he also changed the sizeof(struct ...)'s into the coff |
| 269 | style FOOSZ macros. I'm not sure this is right, but I can't |
| 270 | remember why. xoxorich.] |
| 271 | |
| 272 | Tue Feb 18 02:11:10 1992 K. Richard Pixley (rich at cygnus.com) |
| 273 | |
| 274 | * tc-m88k.[hc]: pulled in from hack's unfinished work. These |
| 275 | aren't yet integrated. |
| 276 | |
| 277 | * tc-i860.[hc]: blew off the dust. Something must still be done |
| 278 | about conflicting relocation types. |
| 279 | |
| 280 | * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the |
| 281 | real thing. |
| 282 | |
| 283 | * tc-i960.c, tc-sparc.c: white space and comments only. |
| 284 | |
| 285 | * tc-a29k.h: delete duplicate macro definition. |
| 286 | |
| 287 | * new file atof-ns32k.c copied from hack's last unreleased gas. |
| 288 | |
| 289 | |
