The order in which instructions are generated by gen_insn() influences
assignment to tmp registers. During generation, tmp instructions (e.g.
generate_V6_vassign_tmp) use vreg_src_off() to determine what kind of
register to use as source. If some instruction (e.g.
generate_V6_vmpyowh_64_acc) uses a tmp register but is generated prior
to the corresponding tmp instruction, the vregs_updated_tmp bit map
isn't updated in time.
Exmple:
{ v14.tmp = v16; v25 = v14 } This works properly because
generate_V6_vassign_tmp is generated before generate_V6_vassign
and the bit map is updated.
{ v15:14.tmp = vcombine(v21, v16); v25:24 += vmpyo(v18.w,v14.h) }
This does not work properly because vmpyo is generated before
vcombine and therefore the bit map does not yet know that there's
a tmp register.
The parentheses in the decoding function were in the wrong place.
Moving them to the correct location makes shuffling of .tmp vector
registers work as expected.

We recently moved glib detection code to meson but this changes the
linker command line from -lglib-2.0 to using a path to libglib-2.0.so.
This does not work for static linking, which is used by stress.c:
$ make V=1 tests/migration/initrd-stress.img
cc -m64 -mcx16 -o tests/migration/stress ... -static -Wl,--start-group
/usr/lib64/libglib-2.0.so -Wl,--end-group
...
bin/ld: attempted static link of dynamic object `/usr/lib64/libglib-2.0.so'
Add a specific dependency for stress.c, which is linked statically.
The compiler command line is now:
cc -m64 -mcx16 -o tests/migration/stress ... -static -pthread
-Wl,--start-group -lm /usr/lib64/libpcre.a -lglib-2.0 -Wl,--end-group

We cannot use the generic reentrancy guard in the LSI code, so
we have to manually prevent endless reentrancy here. The problematic
lsi_execute_script() function has already a way to detect whether
too many instructions have been executed - we just have to slightly
change the logic here that it also takes into account if the function
has been called too often in a reentrant way.
The code in fuzz-lsi53c895a-test.c has been taken from an earlier
patch by Mauro Matteo Cascella.

Though we are already using CONFIG_RTL8139_PCI in the meson.build file
for testing whether the rtl8139 device is available or not, this is not
enough: The CONFIG switch might have been selected by another target
(e.g. the mips fuloong2e machine has the rtl8139 chip soldered on the
board), so CONFIG_RTL8139_PCI ends up in config_all_devices and the
test then gets executed on x86. We need an additional run-time check
to be on the safe side to make this test also work when configure has
been run with "--without-default-devices".

Clean up monitor_event to just use monitor_suspend/monitor_resume,
using mon->mux_out to protect against incorrect nesting (especially
on startup).
The only remaining case of reading suspend_cnt is in the can_read
callback, which is just advisory and can use qatomic_read.
As an extra benefit, mux_out is now simply protected by mon_lock.
Also, moving the prompt to the beginning of the main loop removes
it from the output in some error cases where QEMU does not actually
start successfully. It is not a full fix and it would be nice to
also remove the monitor heading, but this is already a small (though
unintentional) improvement.

Biosbits avocado tests on gitlab has thus far been disabled because some
packages needed by this test was missing in the container images used by gitlab
CI. These packages have now been added with the commit:
da9000784c ("tests/lcitool: Add mtools and xorriso and remove genisoimage as dependencies")
Therefore, this change enables bits avocado test on gitlab.
At the same time, the bits cleanup code has also been made more robust with
this change.

The error message is bad when the section is untagged. For instance,
test case doc-interleaved-section produces "'@foobar:' can't follow
'Note' section", which is okay, but if we drop the "Note:" tag, we get
"'@foobar:' can't follow 'None' section, which is bad.
Change the error message to "description of '@foobar:' follows a
section".

are not available in the binary, thus it won't spoil the output
and the test then passes with such QEMU binaries that have a limited

The test is already fenced with CONFIG_USB_UHCI in meson.build, but in
case we build the ppc or mips targets in parallel, this config switch
is still set in "config_all_devices" and thus the test is still run.
Thus we need an explicit additional check here before adding the tests

Skip TestBlockdevReopen.test_insert_compress_filter() if the 'compress'
driver isn't available.
In order to make the test succeed when the case is skipped, we also need
to remove any output from it (which would be missing in the case where
we skip it). This is done by replacing qemu_io_log() with qemu_io(). In
case of failure, qemu_io() raises an exception with the output of the
qemu-io binary in its message, so we don't actually lose anything.

This commit enables each CXL Type-3 device to contain one volatile
memory region and one persistent region.
Two new properties have been added to cxl-type3 device initialization:
[volatile-memdev] and [persistent-memdev]
The existing [memdev] property has been deprecated and will default the
memory region to a persistent memory region (although a user may assign
the region to a ram or file backed region). It cannot be used in
combination with the new [persistent-memdev] property.
Partitioning volatile memory from persistent memory is not yet supported.
Volatile memory is mapped at DPA(0x0), while Persistent memory is mapped
at DPA(vmem->size), per CXL Spec 8.2.9.8.2.0 - Get Partition Info.

packets as a response to GDB commands that accept it. Now, let's add a
test for this intended behavior. Running this test before the fix from
the previous commit fails as QEMU sends a stop-reply packet
asynchronously, when GDB was in fact waiting an ACK.

Each slot in a packet can be assigned to at most one instruction.
Although the assembler generally ought to enforce this rule, we better
be safe than sorry and also do some check to properly throw an "invalid
packet" exception on wrong slot assignments.
This should also make it easier to debug possible future errors caused
by missing updates to `find_iclass_slots()` rules in
target/hexagon/iclass.c.
