configure: propagate --extra-cflags and --extra-ldflags to meson compile tests
Meson (intentionally) does not add QEMU_CFLAGS to cc.compiles/cc.links
tests, as they are supposed to be independent of the specific sets of
compilation flags used to build the programs. However, the user can
still use CFLAGS or the toolchain file's LANG_args/LANG_link_args option
to specify -I or -L options that apply to cc.compiles/cc.links as well.
This is also the intended use of configure's --extra-cflags,
--extra-cxxflags and --extra-ldflags options. For example, if
one has netmap's header in a nonstandard directory, up to commit
837b84b1c078bf3e909 it used to work fine to do:
.../configure --enable-netmap \
--extra-cflags=-I/path/to/netmap/sys
but since the test was converted to meson, this does not work anymore.
Pass these options to meson via the toolchain file instead of via
config-host.mak, since both have the same purpose.

plugins: try and make plugin_insn_append more ergonomic
Currently we make the assumption that the guest frontend loads all
op code bytes sequentially. This mostly holds up for regular fixed
encodings but some architectures like s390x like to re-read the
instruction which causes weirdness to occur. Rather than changing the
frontends make the plugin API a little more ergonomic and able to
handle the re-read case.
Stuff will still get strange if we read ahead of the opcode but so far
no front ends have done that and this patch asserts the case so we can
catch it early if they do.

plugins/cache: implement unified L2 cache emulation
This adds an implementation of a simple L2 configuration, in which a
unified L2 cache (stores both blocks of instructions and data) is
maintained for each core separately, with no inter-core interaction
taken in account. The L2 cache is used as a backup for L1 and is only
accessed if the wanted block does not exist in L1.
In terms of multi-threaded user-space emulation, the same approximation
of L1 is done, a static number of caches is maintained, and each and
every memory access initiated by a thread will have to go through one of
the available caches.
An atomic increment is used to maintain the number of L2 misses per
instruction.
The default cache parameters of L2 caches is:
2MB cache size
16-way associativity
64-byte blocks

Merge remote-tracking branch 'remotes/berrange/tags/hmp-x-qmp-620-pull-request' into staging
Initial conversion of HMP debugging commands to QMP
This introduces a new policy that all HMP commands will be converted to
have QMP equivalents, marked unstable if no formal QAPI modelling is
intended to be done.
New unstable commands are added as follows:
- HMP "info roms" => QMP "x-query-roms"
- HMP "info profile" => QMP "x-query-profile"
- HMP "info numa" => QMP "x-query-numa"
- HMP "info usb" => QMP "x-query-usb"
- HMP "info rdma" => QMP "x-query-rdma"
- HMP "info ramblock" => QMP "x-query-ramblock"
- HMP "info irq" => QMP "x-query-irq"
- HMP "info jit" => QMP "x-query-jit"
- HMP "info opcount" => QMP "x-query-opcount"

hw/arm/virt: Rename default_bus_bypass_iommu
Since commit
d8fb7d0969d5 ("vl: switch -M parsing to keyval"), machine
parameter definitions cannot use underscores, because keyval_dashify()
transforms them to dashes and the parser doesn't find the parameter.
This affects option default_bus_bypass_iommu which was introduced in the
same release:
$ qemu-system-aarch64 -M virt,default_bus_bypass_iommu=on
qemu-system-aarch64: Property 'virt-6.1-machine.default-bus-bypass-iommu' not found
Rename the parameter to "default-bus-bypass-iommu". Passing
"default_bus_bypass_iommu" is still valid since the underscore are
transformed automatically.
Fixes: 6d7a85483a06 ("hw/arm/virt: Add default_bus_bypass_iommu machine option")

target/arm: Use tcg_constant_i32() in gen_rev16()
Since the mask is a constant value, use tcg_constant_i32()
instead of a TCG temporary.

The immediate value used for comparison is constant and
read-only. Move it to the constant pool. This frees a
TCG temporary for unsigned saturation opcodes.

target/arm: Use the constant variant of store_cpu_field() when possible
When using a constant variable, we can replace the store_cpu_field()
call by store_cpu_field_constant() which avoid using TCG temporaries.

target/arm: Introduce store_cpu_field_constant() helper
Similarly to the store_cpu_field() helper which takes a TCG
temporary, store its value to the CPUState, introduce the
store_cpu_field_constant() helper which store a constant to
CPUState (without using any TCG temporary).
