The three-operand MULT and MULTU are the only R5900-specific
instructions emitted by GCC 7.3. The R5900 also implements the three-
operand MADD and MADDU instructions, but they are omitted in QEMU for
now since they are absent in programs compiled by current GCC versions.

Likewise, the R5900-specific pipeline 1 instruction variants MULT1,
MULTU1, DIV1, DIVU1, MADD1, MADDU1, MFHI1, MFLO1, MTHI1 and MTLO1
are omitted here as well.

The R5900 implements the 64-bit MIPS III instruction set except
DMULT, DMULTU, DDIV, DDIVU, LL, SC, LLD and SCD. The MIPS IV
instructions MOVN, MOVZ and PREF are implemented. It has the
R5900-specific three-operand instructions MADD, MADDU, MULT and
MULTU as well as pipeline 1 versions MULT1, MULTU1, DIV1, DIVU1,
MADD1, MADDU1, MFHI1, MFLO1, MTHI1 and MTLO1. A set of 93 128-bit
multimedia instructions specific to the R5900 is also implemented.

The Toshiba TX System RISC TX79 Core Architecture manual:

https://wiki.qemu.org/File:C790.pdf

describes the C790 processor that is a follow-up to the R5900. There
are a few notable differences in that the R5900 FPU

- is not IEEE 754-1985 compliant,
- does not implement double format, and
- its machine code is nonstandard.

In several places we use assert(FEATURE), and assume that if FEATURE
is disabled, all following code is removed as unreachable.  Which allows
us to compile-out functions that are only present with FEATURE, and
have a link-time failure if the functions remain used.

MinGW does not mark its internal function _assert() as noreturn, so the
compiler cannot see when code is unreachable, which leads to link errors
for this host that are not present elsewhere.

The current build-time failure concerns 62823083, but I remember
having seen this same error before.  Fix it once and for all for MinGW.

When user provides a long domainname or hostname that doesn't fit in the
DHCP packet, we mustn't overflow the response packet buffer. Instead,
report errors, following the g_warning() in the slirp->vdnssearch
branch.

Also check the strlen against 256 when initializing slirp, which limit
is also from the protocol where one byte represents the string length.
This gives an early error before the warning which is harder to notice
or diagnose.

nettle 2.7.1 was released in 2013 and all the distros that are build

  RHEL-7: 2.7.1
  Debian (Stretch): 3.3
  Debian (Jessie): 2.7.1
  OpenBSD (ports): 3.4
  FreeBSD (ports): 3.4
  OpenSUSE Leap 15: 3.4
  Ubuntu (Xenial): 3.2
  macOS (Homebrew): 3.4

Based on this, it is reasonable to require nettle >= 2.7.1 in QEMU
which allows for some conditional version checks in the code to be
removed.

[Error message capitalized for local consistency]
Reviewed-by: NKevin Wolf <kwolf@redhat.com>

bdrv_img_create() takes an Error ** argument and uses it in the
conventional way, except for one place: when qemu_opts_do_parse()
fails, it first reports its error to stderr or the HMP monitor with
error_report_err(), then error_setg()'s a generic error.

When the caller reports that second error similarly, this produces two
consecutive error messages on stderr or the HMP monitor.

When the caller does something else with it, such as send it via QMP,
the first error still goes to stderr or the HMP monitor.  Fortunately,
no such caller exists.

Simply use the first error as is.  Update expected output of
qemu-iotest 049 accordingly.

Calling error_report() from within a function that takes an Error **

it can run within drive_init_func(), which takes an Error ** argument.
drive_init_func()'s caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway:

* Convert drive_new() to Error

* Update add_init_drive() to report the error received from
  drive_new()

Calling error_report() in a function that takes an Error ** argument
is suspicious.  parse_numa() does that, and then fails without setting
an error.  Its caller main(), via qemu_opts_foreach(), is fine with
it, but clean it up anyway.

While there, give parse_numa() internal linkage.

Calling error_report() in a function that takes an Error ** argument
is suspicious.  vnc_init_func() does that, and then fails without
setting an error.  Its caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway.

While there, drop a "Failed to start VNC server: " error message
prefix that doesn't really add value.
