Our official support policy only supports the most recent two
versions of macOS (currently macOS 13 Ventura and macOS 14 Sonoma),
and we already have code that assumes at least macOS 12 Monterey or
better. In commit
2d27c91e2b72ac7 we dropped some of the back-compat
code for older macOS versions, but missed the guard in osdep.h that
is providing a fallback for macOS 10 and earlier.
Simplify the ifdef to the "ifdef __APPLE__" that we use elsewhere for

The asset used in the mentioned test gets truncated before it's used
in the test. This means that the file gets modified, and thus the
asset's expected hash doesn't match anymore. This causes cache misses
and re-downloads every time the test is re-run.
Let's make a copy of the asset so that the one in the cache is
preserved and the cache sees a hit on re-runs.

tests/avocado: mips: add hint for fetchasset plugin
Avocado's fetchasset plugin runs before the actual Avocado job (and
any test). It analyses the test's code looking for occurrences of
"self.fetch_asset()" in the either the actual test or setUp() method.
It's not able to fully analyze all code, though.
The way these tests are written, make the fetchasset plugin blind to
the assets. This adds some more code duplication, true, but it will
aid the fetchasset plugin to download or verify the existence of these
assets in advance.

docs/sphinx/depfile.py: Handle env.doc2path() returning a Path not a str
In newer versions of Sphinx the env.doc2path() API is going to change
to return a Path object rather than a str. This was originally visible
in Sphinx 8.0.0rc1, but has been rolled back for the final 8.0.0
release. However it will probably emit a deprecation warning and is
likely to change for good in 9.0:
https://github.com/sphinx-doc/sphinx/issues/12686
Our use in depfile.py assumes a str, and if it is passed a Path
it will fall over:
Handler <function write_depfile at 0x77a1775ff560> for event 'build-finished' threw an exception (exception: unsupported operand type(s) for +: 'PosixPath' and 'str')
Wrapping the env.doc2path() call in str() will coerce a Path object
to the str we expect, and have no effect in older Sphinx versions
that do return a str.

target/sh4: Avoid shift into sign bit in update_itlb_use()
In update_itlb_use() the variables or_mask and and_mask are uint8_t,
which means that in expressions like "and_mask << 24" the usual C
arithmetic conversions will result in the shift being done as a
signed int type, and so we will shift into the sign bit. For QEMU
this isn't undefined behaviour because we use -fwrapv; but we can
avoid it anyway by using uint32_t types for or_mask and and_mask.

Coverity complains (CID
1547592) that in dump_address_map() we take a

to shift into the sign bit when we construct the value 'logical'.
This isn't a bug for QEMU because we use -fwrapv semantics, but
we can make Coverity happy by using an unsigned type for the loop

target/xtensa: Make use of 'segment' in pptlb helper less confusing
Coverity gets confused about the use of the 'segment' variable in the
pptlb helper function: it thinks that we can take a code path where
we first initialize it:
unsigned segment = XTENSA_MPU_PROBE_B; // 0x40000000
and then use that value as a shift count:
} else if (nhits == 1 && (env->sregs[MPUENB] & (1u << segment))) {
In fact this isn't possible, beacuse xtensa_mpu_lookup() is passed
'&segment', and it uses that as an output value, which it will always
set if it returns nonzero. But the way the code is currently written
is confusing to a human reader as well as to Coverity.
Instead of initializing 'segment' at the top of the function with a
value that's only used in the "nhits == 0" code path, use the
constant value directly in that code path, and don't initialize
segment. This matches the way we use xtensa_mpu_lookup() in its
other callsites in get_physical_addr_mpu().

target/arm: Fix UMOPA/UMOPS of 16-bit values
The UMOPA/UMOPS instructions are supposed to multiply unsigned 8 or
16 bit elements and accumulate the products into a 64-bit element.
In the Arm ARM pseudocode, this is done with the usual
infinite-precision signed arithmetic. However our implementation
doesn't quite get it right, because in the DEF_IMOP_64() macro we do:
sum += (NTYPE)(n >> 0) * (MTYPE)(m >> 0);
where NTYPE and MTYPE are uint16_t or int16_t. In the uint16_t case,
the C usual arithmetic conversions mean the values are converted to
"int" type and the multiply is done as a 32-bit multiply. This means
that if the inputs are, for example, 0xffff and 0xffff then the
result is 0xFFFE0001 as an int, which is then promoted to uint64_t
for the accumulation into sum; this promotion incorrectly sign
extends the multiply.
Avoid the incorrect sign extension by casting to int64_t before
the multiply, so we do the multiply as 64-bit signed arithmetic,
which is a type large enough that the multiply can never
overflow into the sign bit.
(The equivalent 8-bit operations in DEF_IMOP_32() are fine, because
the 8-bit multiplies can never overflow into the sign bit of a
32-bit integer.)

For an instruction which accesses a 128-bit element tile when

we will assert in get_tile_rowcol():
qemu-system-aarch64: ../../tcg/tcg-op.c:926: tcg_gen_deposit_z_i32: Assertion `len > 0' failed.
This happens because we calculate
len = ctz32(streaming_vec_reg_size(s)) - esz;$
but if the SVL and the element size are the same len is 0, and
the deposit operation asserts.
In this case the ZA storage contains exactly one 128 bit
element ZA tile, and the horizontal or vertical slice is just
that tile. This means that regardless of the index value in
the Ws register, we always access that tile. (In pseudocode terms,
we calculate (index + offset) MOD 1, which is 0.)

hw/misc/bcm2835_property: Avoid overflow in OTP access properties
Coverity points out that in our handling of the property
RPI_FWREQ_SET_CUSTOMER_OTP we have a potential overflow. This
happens because we read start_num and number from the guest as
unsigned 32 bit integers, but then the variable 'n' we use as a loop
counter as we iterate from start_num to start_num + number is only an
"int". That means that if the guest passes us a very large start_num
we will interpret it as negative. This will result in an assertion
failure inside bcm2835_otp_set_row(), which checks that we didn't
pass it an invalid row number.
A similar issue applies to all the properties for accessing OTP rows
where we are iterating through with a start and length read from the
guest.
Use uint32_t for the loop counter to avoid this problem. Because in
all cases 'n' is only used as a loop counter, we can do this as
part of the for(), restricting its scope to exactly where we need it.

u32: length: number of palette entries to set (1-256)
u32...: RGBA palette values (offset to offset+length-1)
We get this wrong in a couple of ways:
* we aren't checking the offset and length are in range, so the guest
can make us spin for a long time by providing a large length
* the bounds check on our loop is wrong: we should iterate through
'length' palette entries, not 'length - offset' entries
Fix the loop to implement the bounds checks and get the loop

this switch case, rather than function-global, so it's clearer
