Use the --output-delaylib + switch to create a delay-import library. The resulting app will load the dll + as soon as the first function is called. It will link to __delayLoadHelper2() + from the static delayimp library, which will import LoadLibraryA and + GetProcAddress from kernel32. + +* Add a new command line option, --insn-width=WIDTH, to objdump to specify + number of bytes to be displayed on a single line when disassembling + instructions. + +* Readelf can now display the relocated contents of a section as a sequence + of bytes via the --relocated-dump= command line option. + +* The gprof program has been given a new command line option: + --external-symbols-table= which reads in symbols from a specified + file. + +* The plugin target has been added to bfd. It can load the same shared objects + used by gold and uses them to provide basic support for new file formats. + +* The verilog memory hex dump file format is now supported as an output format + for objcopy. + +* Add --file-alignment, --heap, --image-base, --section-alignment, + --stack and --subsystem command line options to objcopy, which will + set PE optional header. + +* Option --dwarf/-W of objdump is now as flexible as readelf --debug-dump/-w. + +* --as-needed now links in a dynamic library if it satisfies undefined + symbols in regular objects, or in other dynamic libraries. In the + latter case the library is not linked if it is found in a DT_NEEDED + entry of one of the libraries already linked. + +* Added --prefix=PREFIX and --prefix-strip=LEVEL switches to objdump to + add absolute paths for -S. + +* Add new option --use-nul-prefixed-import-tables to dlltool to allow fall- + back to old import table generation with null element prefix. + +* Added --identify-strict switch to cause --identify to + report an error when the import library is associated with + multiple DLLs. + +* Added --identify option to dlltool, which determines the + name of the DLL associated with the specified . + +* Support for PowerPC booke64 instructions has been removed. The assembler no + longer accepts -mbooke32 or -mbooke64 and the disassembler no longer accepts + -Mbooke32 or -Mbooke64. Instead, -mbooke and -Mbooke should be used. + +Changes in 2.19: + +* Added -wL switch to dump decoded contents of .debug_line. + +* Added support for "thin" archives which contain pathnames pointing to + object files rather than the files themselves and which contain a + flattened symbol index for all objects, and archives, which have been + added to the archive. + +* Added -F switch to objdump to include file offsets in the disassembly. + +* Added -c switch to readelf to allow string dumps of archive symbol index. + +* Support for SSE5 has been added to the i386 port. + +* Added -p switch to readelf to allow string dumps of sections. + +Changes in 2.18: + +* Resolved 37 coding problems in bfd including static array overruns, null + pointer dereferences and use of a malloc buffer after it has been freed, as + revealed by static analysis donated by Coverity, Inc. (http://scan.coverity.com). + +* The binutils sources are now released under version 3 of the GNU General + Public License. + +* A new tool "windmc" has been added for some targets. This is a message + compiler which attempts to be compatible with the MS version. + +* Add codepage support to the windres tool. It now supports many new + resource types (e.g. MANIFEST, TOOLBAR, etc). The output generation + for binary files is done now via bfd itself. The endianess problems + for different hosts are solved. Dumps of .res files can now be + re-compiled by windres without lossing resources or compilation errors. + Some problems on dialog resource translations are corrected. + +* Add --extract-symbol command line option to objcopy, which will + strip everything out of an ordinary object file or executable except + for its symbol table. Files containing just symbols can be useful + to some OSes. + +Changes in 2.17: + +* Add "-x NAME" to readelf in addition to "-x NUMBER". + +* Add -i and -t switches to cxxfilt. -i disables the display of implementation + specific extra demangling information (if any) and -t disables the demangling + of types. + +* Add support for the "@" syntax to the command lines of all tools, so + that extra switches can be read from . + +* Add "-W/--dwarf" to objdump to display the contents of the DWARF + debug sections. + +* Add "-t/--section-details" to readelf to display section details. + "-N/--full-section-name" is deprecated. + +* powerpc-linux ld now supports a variant form of PLT and GOT for the security + conscious. 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. + +* gprof now allows input files to have histogram records for + several memory ranges, provided those ranges are disjoint. + +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.
