H.J. Lu 5db04b0965 Support AMD64/Intel ISAs in assembler/disassembler
AMD64 spec and Intel64 spec differ in direct unconditional branches in
64-bit mode.  AMD64 supports direct unconditional branches with 16-bit
offset via the data size prefix, which truncates RIP to 16 bits, while
the data size prefix is ignored by Intel64.

This patch adds -mamd64/-mintel64 option to x86-64 assembler and
-Mamd64/-Mintel64 option to x86-64 disassembler.  The most permissive
ISA, which is AMD64, is the default.

GDB can add an option, similar to

(gdb) help set disassembly-flavor
Set the disassembly flavor.
The valid values are "att" and "intel", and the default value is "att".

to select which ISA to disassemble.

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.

Since we know the max length of the chain, simply abort when we've walked
more times than that.  The only way that could have happened is if there
was a loop.

Andreas Arnez 4ef9f41a95 S390: Support new vector register sections
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.
