The rfdi instruction is part of the e500mc and derivative cores. It came into
binutils in a GPLv3 patch, along with the rest of the e500mc instruction set.
Currently only rfdi is planned to be used, so rather than attempt to backport
the full patch, take a surgical route and add instructions as needed.
MFC after: 2 weeks
us up to version 2.17.50.20070703, at the last GPLv2 commit.
Amongst others, this added upstream support for some FreeBSD-specific
things that we previously had to manually hack in, such as the OSABI
label support, and so on.
There are also quite a number of new files, some for cpu's (e.g. SPU)
that we may or may not be interested in, but those can be cleaned up
later on, if needed.
The change made to bfd/elf.c in upstream revision 1.217.4.3 (which was a
revert of an earlier change), caused objcopy on powerpc to fail to copy
debug info from kernel modules. This had to be fixed by applying the
diff from upstream revision 1.243 on top of it.
Binutils has a "contrib" subdirectory - thus flattening cannot happen
without renaming the upper level contrib directory in a first pass.
Also, don't record this move and remove any keyword expansion.
