Alexander Graf f976b09ea2 PPC: Fix compilation with TCG debug
The recent VSX patches broken compilation of QEMU when configurated
with --enable-debug, as it was treating "target long" TCG variables
as "i64" which is not true for 32bit targets.

This patch fixes all the places that the compiler has found to use
the correct variable type and if necessary manually cast.

Alexander Graf c2b63f0397 PPC: Add VSX to hflags
We generate different code depending on whether MSR_VSX is set or
clear, so it needs to be part of our hflags too which indicate whether
we're still in the same translation block cache bucket.

Tom Musta 551e3ef72e Add xxsel
This patch adds the VSX Select (xxsel) instruction.

The xxsel instruction has four VSR operands.  Thus the xC
instruction decoder is added.

The xxsel instruction is massively overloaded in the opcode
table since only bits 26 and 27 are opcode bits.  This
overloading is done in matrix fashion with two macros
(GEN_XXSEL_ROW and GEN_XX_SEL).

V2: (1) eliminated unecessary XXSEL macro  (2) tighter implementation
using tcg_gen_andc_i64.

Tom Musta df020ce070 Add VSX Scalar Move Instructions
This patch adds the VSX scalar move instructions:

  - xsabsdp (Scalar Absolute Value Double-Precision)
  - xsnabspd (Scalar Negative Absolute Value Double-Precision)
  - xsnegdp (Scalar Negate Double-Precision)
  - xscpsgndp (Scalar Copy Sign Double-Precision)

A common generator macro (VSX_SCALAR_MOVE) is added since these
instructions vary only slightly from each other.

Macros to support VSX XX2 and XX3 form opcodes are also added.
These macros handle the overloading of "opcode 2" space (instruction
bits 26:30) caused by AX and BX bits (29 and 30, respectively).

V3: Per feedback from Paolo Bonzini, moved the sign mask into a
temporary and used andc.

Alexey Kardashevskiy b650d6a2fc target-ppc: move POWER7+ to a separate family
So far POWER7+ was a part of POWER7 family. However it has a different
PVR base value so in order to support PVR masks, it needs a separate
family class.

This adds a new family class, PVR base and mask values and moves
Power7+ v2.1 CPU to a new family. The class init function is copied
from the POWER7 family.

This defines a firmware name for the new family as "PowerPC,POWER7+"
instead of previously used "PowerPC,POWER7" from the POWER7 family.
The reason for that is that the Sapphire firmware (a h0st firmware)
uses "PowerPC,POWER7+" already and since no specification defines
exactly the CPU nodes naming in the device tree, we better stay
in sync with the host firmware.

Alexey Kardashevskiy 3bc9ccc054 powerpc: add PVR mask support
IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported
CPU won't break the existing code.

This adds PVR value/mask support for KVM, i.e. for -cpu host option.

As CPU family class name for POWER7 is "POWER7-family", there is no need
to touch aliases.

James Hogan 97577fd4c3 cpu: Move cpu state syncs up into cpu_dump_state()
The x86 and ppc targets call cpu_synchronize_state() from their
*_cpu_dump_state() callbacks to ensure that up to date state is dumped
when KVM is enabled (for example when a KVM internal error occurs).

Move this call up into the generic cpu_dump_state() function so that
other KVM targets (namely MIPS) can take advantage of it.

This requires kvm_cpu_synchronize_state() and cpu_synchronize_state() to
be moved out of the #ifdef NEED_CPU_H in <sysemu/kvm.h> so that they're
accessible to qom/cpu.c.

Alexander Graf 7bb438b6a1 PPC: KVM: Compile fix for qemu_notify_event
The function qemu_notify_event is defined by a header that we don't
include in the PPC KVM code. Include it to get the code building
again.

Aurelien Jarno 779f659021 target-ppc: fix bit extraction for FPBF and FPL
Bit extraction for the FP BF and L field of the MTFSFI and MTFSF
instructions is wrong and doesn't match the reference manual (which
explain the bit number in big endian format). It has been broken in
commit 7d08d85645.

This patch fixes this, which in turn fixes the problem reported by
Khem Raj about the floor() function of libm.

On POWER7, LPCR_ILE is used to control what endian guests take
their exceptions in so use it instead of MSR_ILE.
