+* The MIPS port now supports the microMIPS Release 5 ISA for assembly and
+ disassembly.
+
+* The MIPS port now supports the Imagination interAptiv MR2 processor,
+ which implements the MIPS32r3 ISA, the MIPS16e2 ASE as well as a couple
+ of implementation-specific regular MIPS and MIPS16e2 ASE instructions.
+
+* The SPARC port now supports the SPARC M8 processor, which implements the
+ Oracle SPARC Architecture 2017.
+
+* The MIPS port now supports the MIPS16e2 ASE for assembly and disassembly.
+
+* Add support for ELF SHF_GNU_MBIND and PT_GNU_MBIND_XXX.
+
+* Add support for the wasm32 ELF conversion of the WebAssembly file format.
+
+* Add --inlines option to objdump, which extends the --line-numbers option
+ so that inlined functions will display their nesting information.
+
+* Add --merge-notes options to objcopy to reduce the size of notes in
+ a binary file by merging and deleting redundant notes.
+
+* Add support for locating separate debug info files using the build-id
+ method, where the separate file has a name based upon the build-id of
+ the original file.
+
+Changes in 2.28:
+
+* This version of binutils fixes a problem with PowerPC VLE 16A and 16D
+ relocations which were functionally swapped, for example,
+ R_PPC_VLE_HA16A performed like R_PPC_VLE_HA16D while R_PPC_VLE_HA16D
+ performed like R_PPC_VLE_HA16A. This could have been fixed by
+ renumbering relocations, which would keep object files created by an
+ older version of gas compatible with a newer ld. However, that would
+ require an ABI update, affecting other assemblers and linkers that
+ create and process the relocations correctly. It is recommended that
+ all VLE object files be recompiled, but ld can modify the relocations
+ if --vle-reloc-fixup is passed to ld. If the new ld command line
+ option is not used, ld will ld warn on finding relocations inconsistent
+ with the instructions being relocated.
+
+* The nm program has a new command line option (--with-version-strings)
+ which will display a symbol's version information, if any, after the
+ symbol's name.
+
+* The ARC port of objdump now accepts a -M option to specify the extra
+ instruction class(es) that should be disassembled.
+
+* The --remove-section option for objcopy and strip now accepts section
+ patterns starting with an exclamation point to indicate a non-matching
+ section. A non-matching section is removed from the set of sections
+ matched by an earlier --remove-section pattern.
+
+* The --only-section option for objcopy now accepts section patterns
+ starting with an exclamation point to indicate a non-matching section.
+ A non-matching section is removed from the set of sections matched by
+ an earlier --only-section pattern.
+
+* New --remove-relocations=SECTIONPATTERN option for objcopy and strip.
+ This option can be used to remove sections containing relocations.
+ The SECTIONPATTERN is the section to which the relocations apply, not
+ the relocation section itself.
+
+Changes in 2.27:
+
+* Add a configure option, --enable-64-bit-archive, to force use of a
+ 64-bit format when creating an archive symbol index.
+
+* Add --elf-stt-common= option to objcopy for ELF targets to control
+ whether to convert common symbols to the STT_COMMON type.
+
+Changes in 2.26:
+
+* Add option to objcopy to insert new symbols into a file:
+ --add-symbol <name>=[<section>:]<value>[,<flags>]
+
+* Add support for the ARC EM/HS, and ARC600/700 architectures.
+
+* Extend objcopy --compress-debug-sections option to support
+ --compress-debug-sections=[none|zlib|zlib-gnu|zlib-gabi] for ELF
+ targets.
+
+* Add --update-section option to objcopy.
+
+* Add --output-separator option to strings.
+
Changes in 2.25:
* Add --data option to strings to only print strings in loadable, initialized
* 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 <implib> to
+* Added --identify-strict switch to cause --identify <implib> to
report an error when the import library is associated with
multiple DLLs.
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.
* Add "--globalize-symbol <name>" and "--globalize-symbols <filename>" 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.
+ several memory ranges, provided those ranges are disjoint.
Changes in 2.16:
* 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.
