Left over .gcno files from old builds can really confuse gcov and the
user expects a clean slate after "make clean". Make clean mean clean.

The gcovr tool is very messy and can leave a lot of crap in the source
tree even when using build directories.

From: Michael Tokarev <mjt@tls.msk.ru>
For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.
It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.
Drop all mentions of libxml2.
[*] Actually the basis for libxml use were introduced in commit
ed279a06c53 ("configure: add dependency") but the implementation
was never merged:

From: Philippe Mathieu-Daudé <f4bug@amsat.org>
The previous commit removed all uses of libxml2.
Refresh lcitool submodule, update qemu.yml and refresh the generated
files by running:
$ make lcitool-refresh
Note: This refreshment also removes libudev dependency on Fedora
and CentOS due to libvirt-ci commit 18bfaee ("mappings: Improve
mapping for libudev"), since "The udev project has been absorbed
by the systemd project", and lttng-ust on FreeBSD runners due to
libvirt-ci commit 6dd9b6f ("guests: drop lttng-ust from FreeBSD
platform").

lcitool doesn't support MSYS2 targets, so manually remove
this now unnecessary library.

On Debian we also need libibumad to enable RDMA:
$ ../configure --enable-rdma
ERROR: OpenFabrics librdmacm/libibverbs/libibumad not present.
Your options:
(1) Fast: Install infiniband packages (devel) from your distro.
(2) Cleanest: Install libraries from www.openfabrics.org
(3) Also: Install softiwarp if you don't have RDMA hardware
Add the dependency to lcitool's qemu.yml (where librdmacm and
libibverbs are already listed) and refresh the generated files
by running:
$ make lcitool-refresh

Personal repos may not have release tags (v6.0.0, v6.1.0, etc) and this
causes cross_system_build_job to fail when pretty-printing a unique
qemu-setup-*.exe name:
version="$(git describe --match v[0-9]*)";
^^^^^^^^^^ fails ^^^^^^^^^^^
mv -v qemu-setup*.exe qemu-setup-${version}.exe;
Fall back to the short commit hash if necessary. This fixes CI failures
that Greg Kurz and I experienced in our personal repos.

currently fails with an error message from git like this:
fatal: not a git repository (or any parent up to mount point /)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
Fix it by changing to the source directory first before updating

I think this addresses the same issue as Phil's series?

-"tcg"
------
-
-Guest code generated by TCG can be traced by defining an event with the "tcg"
-event property. Internally, this property generates two events:
-"<eventname>_trans" to trace the event at translation time, and
-"<eventname>_exec" to trace the event at execution time.
-
-Instead of using these two events, you should instead use the function
-"trace_<eventname>_tcg" during translation (TCG code generation). This function
-will automatically call "trace_<eventname>_trans", and will generate the
-necessary TCG code to call "trace_<eventname>_exec" during guest code execution.
-
-Events with the "tcg" property can be declared in the "trace-events" file with a
-mix of native and TCG types, and "trace_<eventname>_tcg" will gracefully forward
-them to the "<eventname>_trans" and "<eventname>_exec" events. Since TCG values
-are not known at translation time, these are ignored by the "<eventname>_trans"
-event. Because of this, the entry in the "trace-events" file needs two printing
-formats (separated by a comma)::
-
- tcg foo(uint8_t a1, TCGv_i32 a2) "a1=%d", "a1=%d a2=%d"
-
-For example::
-
- #include "trace-tcg.h"
-
- void some_disassembly_func (...)
- {
- uint8_t a1 = ...;
- TCGv_i32 a2 = ...;
- trace_foo_tcg(a1, a2);
- }
-
-This will immediately call::
-
- void trace_foo_trans(uint8_t a1);
-
-and will generate the TCG code to call::
-
- void trace_foo(uint8_t a1, uint32_t a2);
-
-"vcpu"
-------
-
-Identifies events that trace vCPU-specific information. It implicitly adds a
-"CPUState*" argument, and extends the tracing print format to show the vCPU
-information. If used together with the "tcg" property, it adds a second
-"TCGv_env" argument that must point to the per-target global TCG register that
-points to the vCPU when guest code is executed (usually the "cpu_env" variable).
-
-The "tcg" and "vcpu" properties are currently only honored in the root
-./trace-events file.
-
-The following example events::
-
- foo(uint32_t a) "a=%x"
- vcpu bar(uint32_t a) "a=%x"
- tcg vcpu baz(uint32_t a) "a=%x", "a=%x"
-
-Can be used as::
-
- #include "trace-tcg.h"
-
- CPUArchState *env;
- TCGv_ptr cpu_env;
-
- void some_disassembly_func(...)
- {
- /* trace emitted at this point */
- trace_foo(0xd1);
- /* trace emitted at this point */
- trace_bar(env_cpu(env), 0xd2);
- /* trace emitted at this point (env) and when guest code is executed (cpu_env) */
- trace_baz_tcg(env_cpu(env), cpu_env, 0xd3);
- }
-
-If the translating vCPU has address 0xc1 and code is later executed by vCPU
-0xc2, this would be an example output::
-
- // at guest code translation
- foo a=0xd1
- bar cpu=0xc1 a=0xd2
- baz_trans cpu=0xc1 a=0xd3
- // at guest code execution
- baz_exec cpu=0xc2 a=0xd3

Now we have no TCG trace events and no longer handle them in the code
we can remove the handling from the tracetool to generate them. vcpu
tracing is still available although the existing syscall event is an
exercise in redundancy (plugins and -strace can also get the
information).

We won't go fully flexible but for most system emulation 8 vCPUs
resolution should be enough for anybody ;-)

This adds simple instruction matching to the libinsn.so plugin which
is useful for examining the execution distance between instructions.
For example to track how often we flush in ARM due to TLB updates:
-plugin ./tests/plugin/libinsn.so,match=tlbi
which leads to output like this:
0xffffffc01019a918, 'tlbi vale1is, x1', 5702 hits, 31825 match hits, Δ+8112 since last match, 68859 avg insns/match

I think these have been wrong since f193c7979c (do not depend on
thunk.h - more log items). Fix them so as not to confuse other
debugging.

We can't always guarantee we get to the end of a translator loop.
Although this can happen for a variety of reasons it does happen more
often on x86 system emulation when an instruction spans across to an
un-faulted page. This caused confusion of the instruction tracking
data resulting in apparent reverse execution (at least from the
plugins point of view).
Fix this by moving the reset code to plugin_gen_tb_start so we always
start with a clean slate.
