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 =[
