This looks pretty good.  Do you have a copyright assignment with the
FSF?  As far as I know Intel prefers to make copyright assignments on
an individual rather than a company basis.

In general comments should be complete sentences with proper
capitalization and punctuation.  A number of new comments needs to be
fixed.

That comment doesn't quite make sense as written.  Should "of" be
"that"?  Same with the immediately following comment on set_dtndx.

This variable should be named is_direct.

Rather than a hard-coded 4 in "index * 4" I'd prefer to add the struct
to Elf_sizes in elfcpp.h and use that.

Use Elf_sizes here too.

Here too.

Thanks.
