The current chain walker tries to protect itself against loops, by only
works with loops of length 1: a chain that points to itself. If you have
a chain longer than that (3->4->3->4->...), readelf will still hang.

more times than that. The only way that could have happened is if there
was a loop.

The IBM z13 has new 128-bit wide vector registers v0-v31, where v0-v15
include the existing 64-bit wide floating point registers. The Linux
kernel presents the vector registers as two additional register sets,
one for the right halves of v0-v15 and another one for the full
registers v16-v31. Thus a new core file may contain two new register
note sections, and this patch adds support to binutils for them.
