92970812ee docs/devel/testing.rst: add missing newlines after code block
The line immediate following a ".. code::" block is considered
to contains arguments to the "code directive".  The lack of a
new line gives me during at parse time:

   testing.rst:63: (ERROR/3) Error in "code" directive:
   maximum 1 argument(s) allowed, 3 supplied.

   .. code::
     make check-unit V=1

   testing.rst:120: (ERROR/3) Error in "code" directive:
   maximum 1 argument(s) allowed, 3 supplied.

   .. code::
     make check-qtest V=1

Let's add the missing newlines, both for consistency and to
avoid the parsing errors.

808ebd66e4 First RISC-V Patch Set for the 3.1 Soft Freeze
This pull request contains a handful of patches that have been floating
 around various trees for a while but haven't made it upstream.  These
 patches all appear quite safe.  They're all somewhat independent from
 each other:
 
 * One refactors our IRQ management function to allow multiple interrupts
   to be raised an once.  This patch has no functional difference.
 * Cleaning up the op_helper/cpu_helper split.  This patch has no
   functional difference.
 * Updates to various constants to keep them in sync with the latest ISA
   specification and to remove some non-standard bits that snuck in.
 * A fix for a memory leak in the PLIC driver.
 * A fix to our device tree handling to avoid provinging a NULL string.
 
 I've given this my standard test: building the port, booting a Fedora
 root filesytem on the latest Linux tag, and then shutting down that
 image.  Essentially I'm just following the QEMU RISC-V wiki page's
 instructions.  Everything looks fine here.
 
 We have a lot more outstanding patches so I'll definately be submitting
 another PR for the soft freeze.

This kind of ELF for the R5900 relies on an IEEE 754-1985 compliant FPU.
The R5900 FPU hardware is noncompliant and it is therefore emulated in
software by the Linux kernel. QEMU emulates a compliant FPU accordingly.

ed4f49ba9b target/mips: Define the R5900 CPU
The primary purpose of this change is to support programs compiled by
GCC for the R5900 target and thereby run R5900 Linux distributions, for
example Gentoo.

GCC in version 7.3, by itself, by inspection of the GCC source code
and inspection of the generated machine code, for the R5900 target,
only emits two instructions that are specific to the R5900: the three-
operand MULT and MULTU. GCC and libc also emit certain MIPS III
instructions that are not part of the R5900 ISA. They are normally
trapped and emulated by the Linux kernel, and therefore need to be
treated accordingly by QEMU.

A program compiled by GCC is taken to mean source code compiled by GCC
under the restrictions above. One can, with the apparent limitations,
with a bit of effort obtain a fully functioning operating system such
as R5900 Gentoo. Strictly speaking, programs need not be compiled by
GCC to make use of this change.

Instructions and other facilities of the R5900 not implemented by this
change are intended to signal provisional exceptions. One such example
is the FPU that is not compliant with IEEE 754-1985 in system mode. It
is therefore provisionally disabled. In user space the FPU is trapped
and emulated by IEEE 754-1985 compliant software in the kernel, and
this is handled accordingly by QEMU. Another example is the 93
multimedia instructions specific to the R5900 that generate provisional
reserved instruction exception signals.

One of the benefits of running a Linux distribution under QEMU is that
programs can be compiled with a native compiler, where the host and
target are the same, as opposed to a cross-compiler, where they are
not the same. This is especially important in cases where the target
hardware does not have the resources to run a native compiler.

Problems with cross-compilation are often related to host and target
differences in integer sizes, pointer sizes, endianness, machine code,
ABI, etc. Sometimes cross-compilation is not even supported by the
build script for a given package. One effective way to avoid those
problems is to replace the cross-compiler with a native compiler. This
change of compilation methods does not resolve the inherent problems
with cross-compilation.

The native compiler naturally replaces the cross-compiler, because one
typically uses one or the other, and preferably the native compiler
when the circumstances admit this. The native compiler is also a good
test case for the R5900 QEMU user mode. Additionally, Gentoo is well-
known for compiling and installing its packages from sources.

This change has been tested with Gentoo compiled for R5900, including
native compilation of several packages under QEMU.

96631327be target/mips: Make R5900 DMULT[U], DDIV[U], LL[D] and SC[D] user only
The Linux kernel traps certain reserved instruction exceptions to
emulate the corresponding instructions. QEMU plays the role of the
kernel in user mode, so those traps are emulated by accepting the
instructions.

This change adds the function check_insn_opc_user_only to signal a
reserved instruction exception for flagged CPUs in QEMU system mode.

The MIPS III instructions DMULT[U], DDIV[U], LL[D] and SC[D] are not
implemented in R5900 hardware. They are trapped and emulated by the
Linux kernel and, accordingly, therefore QEMU user only instructions.

instructions emitted by GCC 7.3. The R5900 also implements the three-

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