Backports commit fbb04e760f4818a1ba9cfde0a2571a15cd4f49f7 from qemu
9b9c37c364 ("tcg-sparc: Assume v9 cpu always, i.e. force v8plus in
32-bit mode.", 2012-09-21) removed the need for this variable and
most of the references to it, but this one.
Remove defunct code, no effect or functionality change expected.
Backports commit edd318b7a3c54321ead363ffc1e22ebac5785f1d from qemu
Intel CooperLake cpu adds AVX512_BF16 instruction, defining as
CPUID.(EAX=7,ECX=1):EAX[bit 05].
The patch adds a property for setting the subleaf of CPUID leaf 7 in
case that people would like to specify it.

Backports commit 80db491da4ce8b199e0e8d1e23943b20aab82f69 from qemu
The x86 architecture requires that all conversions from floating
point to integer which raise the 'invalid' exception (infinities of
both signs, NaN, and all values which don't fit in the destination
integer) return what the x86 spec calls the "indefinite integer
value", which is 0x8000_0000 for 32-bits or 0x8000_0000_0000_0000 for
64-bits. The softfloat functions return the more usual behaviour of
positive overflows returning the maximum value that fits in the
destination integer format and negative overflows returning the
minimum value that fits.
Wrap the softfloat functions in x86-specific versions which
detect the 'invalid' condition and return the indefinite integer.
Note that we don't use these wrappers for the 3DNow! pf2id and pf2iw
instructions, which do return the minimum value that fits in
an int32 if the input float is a large negative number.

Backports commit 1e8a98b53867f61da9ca09f411288e2085d323c4 from qemu
This patch moves the define of target access alignment earlier from
target/foo/cpu.h to configure.
Suggested in Richard Henderson's reply to "[PATCH 1/4] tcg: TCGMemOp is now
accelerator independent MemOp"
Backports commit 52bf9771fdfce98e98cea36a17a18915be6f6b7f from qemu
We can tell that a decodetree input file is "secondary" when it
uses an argument set marked "!extern". This indicates that at
least one of the insn translation functions will have already
been declared by the "primary" input file, but given only the
secondary we cannot tell which.
Avoid redundant declaration warnings by suppressing them with pragmas.
Backports commit c692079597d98337b6f25deff7599afe39b2a468 from qemu
We should avoid including the whole of softfloat headers in cpu.h and
explicitly include it only where we will be calling softfloat
functions. We can use the -types.h and -helpers.h in cpu.h for the few
bits that are global.
Backports commit 135b03cb9defbd080b8834b30e3d45bed00c6137 from qemu
We should avoid including the whole of softfloat headers in cpu.h and
explicitly include it only where we will be calling softfloat
functions. We can use the -types.h in cpu.h for the few bits that are
global. We also move the restore_snan_bit_mode into internal.h and
include -helpers.h there.
Backports commit 502700d0674919309a19bfd016ea0680c6b7747d from qemu
This is not a normal header and should only be included in the main
softfloat.c file to bring in the various target specific
specialisations. Indeed as it contains non-inlined C functions it is
not even a legal header. Rename it to match our included C convention.
Backports commit 00f43279a3e5e7ea3a0fa853157863663e838e2e from qemu
The macros use the "flags" type and to be consistent if anyone just
needs the macros we should bring in the header we need. There is an
outstanding TODO to audit the use of "flags" and replace with bool at
which point this include could be dropped.
Backports commit 5937fb63a92d54cc4e5270256e4387c4d3a70091 from qemu
There are a bunch of users of the inline helpers who do not need
access to the entire softfloat API. Move those inline helpers into a
new header file which can be included without bringing in the rest of
the world.
Backports commit e34c47ea3fb5f324b58db117b3c010a494c8d6ca from qemu
In our quest to eliminate the home rolled LIT64 macro we fixup usage
inside for m68k's many constants.
Backports commit e23263004d5fea809ad0f78c523f498e04ba788f from qemu
In our quest to eliminate the home rolled LIT64 macro we fixup usage
inside the softfloat code. While we are at it we remove some of the
extraneous spaces to closer fit the house style.
