Fix binutils compilation error with Clang 8

2019-03-05T04:16:50+00:00

Summary:
This change fixes the following compilation error when using clang 8 to cross
compile base to powerpc64:

```
/usr/src/gnu/usr.bin/binutils/libopcodes/../../../../contrib/binutils/opcodes/ppc-dis.c:100:35:
error: arithmetic on a null pointer treated as a cast from integer to pointer is
a GNU extension [-Werror,-Wnull-pointer-arithmetic]
  info->private_data = (char *) 0 + dialect;
		       ~~~~~~~~~~ ^
1 error generated.
*** [ppc-dis.o] Error code 1

make[6]: stopped in /usr/src/gnu/usr.bin/binutils/libopcodes
1 error
```

Test Plan:
- buildworld for x86_64 (native)
- buildworld for powerpc64 (cross)
- buildworld for powerpc64 (native)

gnu binutils: FSGSBASE assembly/disassembly

2017-09-05T19:04:07+00:00

Enable the in-tree binutils to assemble and disassemble amd64 FSGSBASE
instructions (rdfsbase, rdgsbase, wrfsbase, wrgsbase), used in the base
system since r322763.

This gives one last gasp for in-tree gcc, and provides a small
enhancement for in-tree binutils objdump.

Add rfdi opcode to binutils

2017-02-01T02:42:45+00:00

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.

Add some opcodes for assembling forthcoming VSX (Vector-Scalar eXtension)

2015-02-22T20:52:29+00:00

support in the kernel. Userspace programs are expected to rely on LLVM's
integrated assembler or newer binutils.

Add support for the 'rdseed' instruction.

For GNU as, add two missing modes for each of the fcomip and fucomip

instructions.  Partially obtained from OpenBSD by Pedro Giffuni, while I
added the fcomip variants.

Apparently this should help with compiling certain variants of WebKit.
