1-*- text -*- 2 3* A new tool "windmc" has been added for some targets. This is a message 4 compiler which attempts to be compatible with the MS version. 5 6* Add codepage support to the windres tool. It now supports many new 7 resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation 8 for binary files is done now via bfd itself. The endianess problems 9 for different hosts are solved. Dumps of .res files can now be 10 re-compiled by windres without lossing resources or compilation errors. 11 Some problems on dialog resource translations are corrected. 12 13* Add --extract-symbol command line option to objcopy, which will 14 strip everything out of an ordinary object file or executable except 15 for its symbol table. Files containing just symbols can be useful 16 to some OSes. 17 18* Add "-x NAME" to readelf in addition to "-x NUMBER". 19 20* Add -i and -t switches to cxxfilt. -i disables the display of implementation 21 specific extra demangling information (if any) and -t disables the demangling 22 of types. 23 24* Add support for the "@<file>" syntax to the command lines of all tools, so 25 that extra switches can be read from <file>. 26 27* Add "-W/--dwarf" to objdump to display the contents of the DWARF 28 debug sections. 29 30* Add "-t/--section-details" to readelf to display section details. 31 "-N/--full-section-name" is deprecated. 32 33* powerpc-linux ld now supports a variant form of PLT and GOT for the security 34 conscious. This form will automatically be chosen when ld detects that all 35 code in regular object files was generated by gcc -msecure-plt. The old PLT 36 and GOT may be forced by a new ld option, --bss-plt. 37 38* Add "-i/--inlines" to addr2line to print enclosing scope information 39 for inlined function chains, back to first non-inlined function. 40 41* Add "-N/--full-section-name" to readelf to display full section name. 42 43* Add "-M entry:<addr>" switch to objdump to specify a function entry address 44 when disassembling VAX binaries. 45 46* Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches 47 to objcopy to convert local symbols into global symbols. 48 49* gprof now allows input files to have histogram records for 50 several memory ranges, provided those ranges are disjoint. 51 52Changes in 2.16: 53 54* Add "-g/--section-groups" to readelf to display section groups. 55 56* objcopy recognizes two new options --strip-unneeded-symbol and 57 --strip-unneeded-symbols, namely for use together with the wildcard 58 matching the original --strip-symbol/--strip-symbols provided, but 59 retaining any symbols matching but needed by relocations. 60 61* readelf can now display address ranges from .debug_range sections. This 62 happens automatically when a DW_AT_range attribute is encountered. The 63 command line switch --debug-dump=Ranges (or -wR) can also be used to display 64 the contents of the .debug_range section. 65 66* nm and objdump now have a switch "--special-syms" to enable the displaying of 67 symbols which the target considers to be special. By default these symbols 68 are no longer displayed. Currently the only special symbols are the Mapping 69 symbols used by the ARM port to mark transitions between text and data and 70 between ARM and THUMB code. 71 72* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional 73 import and export symbols with <preifx> prepended to them. 74 75Changes in 2.15: 76 77* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the 78 disassembler to print the "raw" mips instruction mnemonic instead of some 79 pseudo instruction name. I.E. print "daddu" or "or" instead of "move", 80 "sll" instead of "nop", etc. 81 82* objcopy and strip can now take wildcard patterns in symbol names specified on 83 the command line provided that the --wildcard switch is used to enable them. 84 85* readelf can now parse archives. 86 87* objdump now accepts --debugging-tags to print the debug information in a 88 format compatible with ctags tool. 89 90* objcopy and strip now accept --only-keep-debug to create a file containing 91 those sections that would be stripped out by --strip-debug. The idea is that 92 this can be used in conjunction with the --add-gnu-debuglink switch to create 93 a two part program distribution - one a stripped executable and the other the 94 debugging info. 95 96* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink 97 section into a (presumably stripped) executable. This allows the debug 98 information for the file to be held in a separate file. 99 100* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX 101 single-character representation. This can be checked by running nm 102 with the -a switch. 103 104Changes in 2.14: 105 106* Added --info switch to objcopy and strip. 107 108* Support for Vitesse IQ2000 added by Red Hat. 109 110* Added 'S' encoding to strings to allow the display of 8-bit characters. 111 112* Added --prefix-symbols=<text>, --prefix-sections=<text> and 113 --prefix-alloc-sections=<text> to objcopy. 114 115* readelf can handle the extensions to the DWARF2 spec used by the Unified 116 Parallel C compiler. 117 118* BFD no longer declares a "boolean" type, to avoid clashes with other 119 headers that declare the same. Users of BFD should replace boolean, 120 false and true, with int, 0 and 1, or define their own boolean type. 121 122* Support for IP2K added by Denis Chertykov. 123 124Changes in 2.13: 125 126* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 127 and FR500 included. 128 129Changes in version 2.12: 130 131* Support for Don Knuth's MMIX, by Hans-Peter Nilsson. 132 133* size: Add --totals to display summary of sizes (Berkeley format only). 134 135* readelf: Add --wide option to not break section header or segment listing 136 lines to fit into 80 columns. 137 138* strings: Add --encoding to display wide character strings. By Markus Kuhn. 139 140* objcopy: Add --rename-section to change section names. 141 142* readelf: Support added for DWARF 2.1 extensions. Support added for 143 displaying the contents of .debug.macinfo sections. 144 145* New command line switches added to objcopy to allow symbols to be kept as 146 global symbols, and also to specify files containing lists of such symbols. 147 by Honda Hiroki. 148 149* Support for OpenRISC by Johan Rydberg. 150 151* New command line switch to objcopy --alt-machine-code which creates a binary 152 with an alternate machine code if one is defined in the architecture 153 description. Only supported for ELF targets. By Alexandre Oliva. 154 155* New command line switch to objcopy -B (or --binary-architecture) which sets 156 the architecture of the output file to the given argument. This option only 157 makes sense, if the input target is binary. Otherwise it is ignored. 158 By Stefan Geuken. 159 160* Support for PDP-11 by Lars Brinkhoff. 161 162Changes in binutils 2.11: 163 164* Add support for ARM v5t and v5te architectures and Intel's XScale ARM 165 extenstions. 166 167* Add --srec-len and --srec-forceS3 command line switch to objcopy. 168 By Luciano Gemme. 169 170* Support for the MIPS32, by Anders Norlander. 171 172* Support for the i860, by Jason Eckhardt. 173 174* Support for CRIS (Axis Communications ETRAX series). 175 176Changes in binutils 2.10: 177 178* Support for 64-bit ELF on HPPA. 179 180* New command line switch to objdump --file-start-context which shows the 181 entire file contents up to the source line first encountered for a given 182 file. 183 184* New command line switch to objdump -M (or --disassembler-options) which takes 185 a parameter which can then be interpreted on a per-target basis by the 186 disassembler. Used by ARM targets to select register name sets, ISA, APCS or 187 raw verions. 188 189* objdump support for -mi386:intel which causes disassembly to be displayed 190 with intel syntax. 191 192* New program: readelf. This displays the contents of ELF format files, 193 regardless of target machine. 194 195* objcopy now takes --change-section-lma, --change-section-vma, and 196 --change-section-address options. The old --adjust-section-vma option is 197 equivalent to --change-section-address. The other --adjust-* options are now 198 renamed to --change-*, although --adjust-* continues to work. 199 200* objcopy has a --redefine-sym option that lets you rename symbols. 201 202* objcopy now takes a -j/--only-section option to copy only the specified 203 sections. 204 205* dlltool now supports the IMPORTS command. 206 207* dlltool now takes --export-all-symbols, --no-export-all-symbols, 208 --exclude-symbols, and --no-default-excludes options. 209 210Changes in binutils 2.9: 211 212* Added windres program, which can be used to manipulate resources in WIN32 213 files as used on Windows 95 and Windows NT. 214 215* The objcopy --gap-fill and --pad-to options operate on the LMA rather than 216 the VMA of the sections. 217 218* Added S modifier to ar to not build a symbol table. 219 220Changes in binutils 2.8: 221 222* The objdump disassembly format has been changed, and hopefully improved. Use 223 the new --prefix-addresses option to get the old format. There are also new 224 --disassemble-zeroes and --no-show-raw-insn options which affect disassembler 225 output. 226 227* Formats may now be specified as configuration triplets. For example, 228 objdump -b i386-pc-linux. The triplets are not passed through config.sub, 229 so they must be in canonical form. 230 231* Added new addr2line program. This uses the debugging information to convert 232 an address into a file name and line number within a program. 233 234* Added --change-leading-char argument to objcopy. 235 236* Added --weaken argument to objcopy. 237 238* objdump --dynamic-reloc now works on ELF executables and shared libraries. 239 240* Added --adjust-vma option to objdump. 241 242* Added -C/--demangle option to objdump. 243 244* Added -p/--preserve-dates option to strip and objcopy. 245 246Changes in binutils 2.7: 247 248* Added --enable-shared and --enable-commonbfdlib options to configure. 249 250* Added --debugging argument to objdump and objcopy. 251 252* Added --defined-only argument to nm. 253 254* Added --remove-leading-char argument to objcopy. 255 256* The objdump --line-numbers option is now meaningful with --reloc. 257 258* Added --line-numbers option to nm. 259 260* Added --endian/-EB/-EL option to objdump. 261 262* Added support for Alpha OpenVMS/AXP. 263 264Changes in binutils 2.6: 265 266* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. 267 268* Added several arguments to objcopy to provide some control over how the new 269 file is laid out in memory. Also added binary output format to BFD to permit 270 generating plain binary files. 271 272* Added --start-address and --stop-address options to objdump. 273 274* ar and ranlib now work on AIX. The tools are now built by default on AIX. 275 276Changes in binutils 2.5: 277 278* Changed objdump -dr to dump the relocs interspersed with the assembly 279 listing, for a more useful listing of relocatable files. 280 281* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. 282 Added -D/--disassemble-all option to disassemble all sections. 283 284* Added --size-sort option to nm. 285 286* strip and objcopy should now be able to handle dynamically linked ELF 287 executables. 288 289Changes in binutils 2.4: 290 291* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and 292 PowerPC (except ar and ranlib; by Ian Taylor). 293 294* Support for Irix 5. 295 296* Programs `strip' and `objcopy' will not attempt to write dynamically linked 297 ELF output files, since BFD currently can't create them properly. 298 299Changes in binutils 2.3: 300 301* A new --stabs argument has been added to objdump to dump stabs sections in 302 ELF and COFF files. 303 304* A new program, nlmconv, has been added. It can convert object files into 305 Novell NetWare Loadable Modules. 306 307* The strings program has been added. 308 309Changes in binutils 2.2: 310 311* The 'copy' program has been renamed to 'objcopy', for consistency with 312 'objdump', and because 'copy' might more plausibly be used as a synonym for 313 'cp'. 314 315* The new stand-alone program c++filt is a filter that converts encoded 316 (mangled) C++ assembly-level identifiers to user-level names. (Note: This 317 may get moved to the gcc distribution.) 318 319* nm -o on an archive now prefixes each line with the archive name, matching 320 the output from BSD nm. 321 322* ar (and ld) can now read (but not write) BSD4.4-style archives. 323 324* New support for H8500, Z8000, and the Hitach SH. 325 326* Dis-assembler interface changed to allow sharing with gdb. 327 328* There is new Elf code, but it is not yet ready for general use. 329 330* There is the beginnings of a test suite. 331 332Changes in binutils 2.1: 333 334* There is now support for writing ECOFF files, so ld and the other utilities 335 should work on Risc/Ultrix and Irix. Please let us know how well this works. 336 337* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD 338 version), if there are any object files in the archive. So running ranlib is 339 now redundant (unless the non-standard q command is used). This is required 340 for Posix.2 conformance. 341 342* The archive-reading code now reads both BSD-style and SYSV-style archives 343 independently of the selected target format. This is to encourage people to 344 switch to SYSV-format, which has a number of advantages. 345 346* The strip and copy programs now have options to remove debug-symbols only 347 and/or local symbols only. They now also support long options. 348 349 350Local variables: 351fill-column: 79 352End: 353
