This form will automatically be chosen when ld detects that all - code in regular object files was generated by gcc -msecure-plt. The old PLT - and GOT may be forced by a new ld option, --bss-plt. - -* Add "-i/--inlines" to addr2line to print enclosing scope information - for inlined function chains, back to first non-inlined function. - -* Add "-N/--full-section-name" to readelf to display full section name. - -* Add "-M entry:<addr>" switch to objdump to specify a function entry address - when disassembling VAX binaries. - -* Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" switches - to objcopy to convert local symbols into global symbols. - -Changes in 2.16: - -* Add "-g/--section-groups" to readelf to display section groups. - -* objcopy recognizes two new options --strip-unneeded-symbol and - --strip-unneeded-symbols, namely for use together with the wildcard - matching the original --strip-symbol/--strip-symbols provided, but - retaining any symbols matching but needed by relocations. - -* readelf can now display address ranges from .debug_range sections. This - happens automatically when a DW_AT_range attribute is encountered. The - command line switch --debug-dump=Ranges (or -wR) can also be used to display - the contents of the .debug_range section. - -* nm and objdump now have a switch "--special-syms" to enable the displaying of - symbols which the target considers to be special. By default these symbols - are no longer displayed. Currently the only special symbols are the Mapping - symbols used by the ARM port to mark transitions between text and data and - between ARM and THUMB code. - -* dlltool has a switch "--ext-prefix-alias <prefix>" to generate additional - import and export symbols with <preifx> prepended to them. - -Changes in 2.15: - -* objcopy for MIPS targets now accepts "-M no-aliases" as an option to the - disassembler to print the "raw" mips instruction mnemonic instead of some - pseudo instruction name. I.E. print "daddu" or "or" instead of "move", - "sll" instead of "nop", etc. - -* objcopy and strip can now take wildcard patterns in symbol names specified on - the command line provided that the --wildcard switch is used to enable them. - -* readelf can now parse archives. - -* objdump now accepts --debugging-tags to print the debug information in a - format compatible with ctags tool. - -* objcopy and strip now accept --only-keep-debug to create a file containing - those sections that would be stripped out by --strip-debug. The idea is that - this can be used in conjunction with the --add-gnu-debuglink switch to create - a two part program distribution - one a stripped executable and the other the - debugging info. - -* objcopy now accepts --add-gnu-debuglink=<file> to insert a .gnu_debuglink - section into a (presumably stripped) executable. This allows the debug - information for the file to be held in a separate file. - -* BFD marks the sections .comment and .note as 'n' in the BSD/POSIX - single-character representation. This can be checked by running nm - with the -a switch. - -Changes in 2.14: - -* Added --info switch to objcopy and strip. - -* Support for Vitesse IQ2000 added by Red Hat. - -* Added 'S' encoding to strings to allow the display of 8-bit characters. - -* Added --prefix-symbols=<text>, --prefix-sections=<text> and - --prefix-alloc-sections=<text> to objcopy. - -* readelf can handle the extensions to the DWARF2 spec used by the Unified - Parallel C compiler. - -* BFD no longer declares a "boolean" type, to avoid clashes with other - headers that declare the same. Users of BFD should replace boolean, - false and true, with int, 0 and 1, or define their own boolean type. - -* Support for IP2K added by Denis Chertykov. - -Changes in 2.13: - -* Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 - and FR500 included. - -Changes in version 2.12: - -* Support for Don Knuth's MMIX, by Hans-Peter Nilsson. - -* size: Add --totals to display summary of sizes (Berkeley format only). - -* readelf: Add --wide option to not break section header or segment listing - lines to fit into 80 columns. - -* strings: Add --encoding to display wide character strings. By Markus Kuhn. - -* objcopy: Add --rename-section to change section names. - -* readelf: Support added for DWARF 2.1 extensions. Support added for - displaying the contents of .debug.macinfo sections. - -* New command line switches added to objcopy to allow symbols to be kept as - global symbols, and also to specify files containing lists of such symbols. - by Honda Hiroki. - -* Support for OpenRISC by Johan Rydberg. - -* New command line switch to objcopy --alt-machine-code which creates a binary - with an alternate machine code if one is defined in the architecture - description. Only supported for ELF targets. By Alexandre Oliva. - -* New command line switch to objcopy -B (or --binary-architecture) which sets - the architecture of the output file to the given argument. This option only - makes sense, if the input target is binary. Otherwise it is ignored. - By Stefan Geuken. - -* Support for PDP-11 by Lars Brinkhoff. - -Changes in binutils 2.11: - -* Add support for ARM v5t and v5te architectures and Intel's XScale ARM - extenstions. - -* Add --srec-len and --srec-forceS3 command line switch to objcopy. - By Luciano Gemme. - -* Support for the MIPS32, by Anders Norlander. - -* Support for the i860, by Jason Eckhardt. - -* Support for CRIS (Axis Communications ETRAX series). - -Changes in binutils 2.10: - -* Support for 64-bit ELF on HPPA. - -* New command line switch to objdump --file-start-context which shows the - entire file contents up to the source line first encountered for a given - file. - -* New command line switch to objdump -M (or --disassembler-options) which takes - a parameter which can then be interpreted on a per-target basis by the - disassembler. Used by ARM targets to select register name sets, ISA, APCS or - raw verions. - -* objdump support for -mi386:intel which causes disassembly to be displayed - with intel syntax. - -* New program: readelf. This displays the contents of ELF format files, - regardless of target machine. - -* objcopy now takes --change-section-lma, --change-section-vma, and - --change-section-address options. The old --adjust-section-vma option is - equivalent to --change-section-address. The other --adjust-* options are now - renamed to --change-*, although --adjust-* continues to work. - -* objcopy has a --redefine-sym option that lets you rename symbols. - -* objcopy now takes a -j/--only-section option to copy only the specified - sections. - -* dlltool now supports the IMPORTS command. - -* dlltool now takes --export-all-symbols, --no-export-all-symbols, - --exclude-symbols, and --no-default-excludes options. - -Changes in binutils 2.9: - -* Added windres program, which can be used to manipulate resources in WIN32 - files as used on Windows 95 and Windows NT. - -* The objcopy --gap-fill and --pad-to options operate on the LMA rather than - the VMA of the sections. - -* Added S modifier to ar to not build a symbol table. - -Changes in binutils 2.8: - -* The objdump disassembly format has been changed, and hopefully improved. Use - the new --prefix-addresses option to get the old format. There are also new - --disassemble-zeroes and --no-show-raw-insn options which affect disassembler - output. - -* Formats may now be specified as configuration triplets. For example, - objdump -b i386-pc-linux. The triplets are not passed through config.sub, - so they must be in canonical form. - -* Added new addr2line program. This uses the debugging information to convert - an address into a file name and line number within a program. - -* Added --change-leading-char argument to objcopy. - -* Added --weaken argument to objcopy. - -* objdump --dynamic-reloc now works on ELF executables and shared libraries. - -* Added --adjust-vma option to objdump. - -* Added -C/--demangle option to objdump. - -* Added -p/--preserve-dates option to strip and objcopy. - -Changes in binutils 2.7: - -* Added --enable-shared and --enable-commonbfdlib options to configure. - -* Added --debugging argument to objdump and objcopy. - -* Added --defined-only argument to nm. - -* Added --remove-leading-char argument to objcopy. - -* The objdump --line-numbers option is now meaningful with --reloc. - -* Added --line-numbers option to nm. - -* Added --endian/-EB/-EL option to objdump. - -* Added support for Alpha OpenVMS/AXP. - -Changes in binutils 2.6: - -* Added -N/--strip-symbol and -K/--keep-symbol arguments to strip and objcopy. - -* Added several arguments to objcopy to provide some control over how the new - file is laid out in memory. Also added binary output format to BFD to permit - generating plain binary files. - -* Added --start-address and --stop-address options to objdump. - -* ar and ranlib now work on AIX. The tools are now built by default on AIX. - -Changes in binutils 2.5: - -* Changed objdump -dr to dump the relocs interspersed with the assembly - listing, for a more useful listing of relocatable files. - -* Changed objdump -d/--disassemble to only disassemble SEC_CODE sections. - Added -D/--disassemble-all option to disassemble all sections. - -* Added --size-sort option to nm. - -* strip and objcopy should now be able to handle dynamically linked ELF - executables. - -Changes in binutils 2.4: - -* Support for HP-PA (by Jeff Law), i386 Mach (by David Mackenzie), RS/6000 and - PowerPC (except ar and ranlib; by Ian Taylor). - -* Support for Irix 5. - -* Programs `strip' and `objcopy' will not attempt to write dynamically linked - ELF output files, since BFD currently can't create them properly. - -Changes in binutils 2.3: - -* A new --stabs argument has been added to objdump to dump stabs sections in - ELF and COFF files. - -* A new program, nlmconv, has been added. It can convert object files into - Novell NetWare Loadable Modules. - -* The strings program has been added. - -Changes in binutils 2.2: - -* The 'copy' program has been renamed to 'objcopy', for consistency with - 'objdump', and because 'copy' might more plausibly be used as a synonym for - 'cp'. - -* The new stand-alone program c++filt is a filter that converts encoded - (mangled) C++ assembly-level identifiers to user-level names. (Note: This - may get moved to the gcc distribution.) - -* nm -o on an archive now prefixes each line with the archive name, matching - the output from BSD nm. - -* ar (and ld) can now read (but not write) BSD4.4-style archives. - -* New support for H8500, Z8000, and the Hitach SH. - -* Dis-assembler interface changed to allow sharing with gdb. - -* There is new Elf code, but it is not yet ready for general use. - -* There is the beginnings of a test suite. - -Changes in binutils 2.1: - -* There is now support for writing ECOFF files, so ld and the other utilities - should work on Risc/Ultrix and Irix. Please let us know how well this works. - -* ar now automatically creates a symbol table (a __.SYMDEF member, in the BSD - version), if there are any object files in the archive. So running ranlib is - now redundant (unless the non-standard q command is used). This is required - for Posix.2 conformance. - -* The archive-reading code now reads both BSD-style and SYSV-style archives - independently of the selected target format. This is to encourage people to - switch to SYSV-format, which has a number of advantages. - -* The strip and copy programs now have options to remove debug-symbols only - and/or local symbols only. They now also support long options. - - -Local variables: -fill-column: 79 -End: |
