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