-*- text -*-
* The nm program has a new command lien option (--with-version-strings)
* 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.
