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:" switch to objdump to specify a function entry address + when disassembling VAX binaries. + +* Add "--globalize-symbol " and "--globalize-symbols " 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 " to generate additional + import and export symbols with 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= 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=, --prefix-sections= and + --prefix-alloc-sections= 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.
