The SR register in the `CPUM68KState` struct does not contain the value
of the lower 5 flags. To compute them, we must OR the CCR values with
the SR register to get the true SR value.

ci(rust): rework workflow
The notable changes are migrating to
`actions-rust-lang/setup-rust-toolchain` for setting up Rust as it's
maintained, and using `katyo/publish-crates` for publishing crates in a
workspace

fix(rust): correct unsound pointer cast
The size of `T` is not guaranteed to be the size of `i32` - all we know
is that `T` is `Into<i32>`, so we should first copy them over into an
`i32` array

fix(mips): lowercase enum name `uc_mips_reg`
This aligns with other architectures
Co-authored-by: Amaan Qureshi <amaanq12@gmail.com>
This hack was introduced in issue#287 which later becomes endless maintainance pain.
=====
Our previous check_exit_request use `brcond` in the middle of a TranslationBlock which
breaks the assumptions and thus a hack to liveness_pass_1 is used for _all_ brcond instructions
which causes issues for MIPS and many other scenarios.
=====
This patch also resolves PC not sync-ed when no memory hooks are installed, finally. Now
Unicorn will always have correct PC no matter what happens.
* use hwaddr for paddrs
* Fix the truncation for memory hooks as well
* Add LPAE regression test

* memory snapshots fix use after free on flatview copy
When restoring a snapshot with memory the flatview must be restored
before the memory reagions are filtered. Because the
AddressSpaceDispatcher also has pointer to the MemoryRegions and on copy
they need to be cleared. The memory_filter_subregions function frees
MemoryRegions which are not used at the time of the snapshot.
* fix some memleaks in tests
These tests has forgott to call uc_close(uc), which lead to memory
leaks. Found by the LeakSanitizer.
* memory snapshots correct clean up container memory regions
* Fix further stackoverflow in tests

* Support mips64 - write correct pc register width on uc_emu_start
* Convert to UC_MODE_MIPS64
* Correctly select MIPS64 CPU model
* Simple 64-bit test - check it doesn't crash

* Comment
* Comment
* Add offset when indexing cpu model, makes tests work on older python
* Move test
* add PC check to test
* Fix test - add python version check
* Use RegressTest method for assert
This code was commented out since 2021, but by default, the error
codewas initialized to `UC_REG_OK`, so there was no error returned
untila result, any write to `UC_ARM_REG_C1_C0_2` returned an error.

- Refreshed the TO BE CHECKED regress tests to either update or remove the skip conditions
- Added a test to check if the created sdist archive is ok
- Added fullMode input in workflow_dispatch
- Take decision whether to build either in debug or release mode and if to build for all python versions according to the commit message patterns
- Set proper artifact names
- Removed not needed steps
- Compacted some steps in order to leverage more the matrix feature
- Bumped cibuildwheel action to 2.22.0
- Run actual regress tests in place of sample scripts
- Specify optional test install in pyproject.toml with proper requirements
- Derive package version from git tags
- Add GENERATORS env var support in setup.py to specify cmake generator and minor refactoring
- Minor cleanup/refactoring for the regress test suite
- Marked some regress tests with skipIf to skip them in case of old python versions
- Marked some failing regress tests to be checked with skipIf
Unlike some other architectures, RISC-V does not expose the current
privilege mode in any architecturally-defined register. That is intentional
to make it easier to implement virtualization in software, but a Unicorn
caller operates outside of the emulated hart and so it can and should be
able to observe and change the current privilege mode in order to properly
emulate certain behaviors of a real CPU.
The current privilege level is therefore now exposed as a new
pseudo-register using the name "priv", which matches the name of the
virtual register used by RISC-V's debug extension to allow the debugger
to read and change the privilege mode while the hart is halted. Unicorn's
use of it is conceptually similar to a debugger.
The bit encoding of this register is the same as specified in RISC-V Debug
Specification v1.0-rc3 Section 4.10.1. It's defined as a "virtual"
register exposing a subset of fields from the dcsr register, although here
it's implemented directly inside the Unicorn code because QEMU doesn't
currently have explicit support for the CSRs from the debug specification.
If it supports "dcsr" in a future release then this implementation could
change to wrap reading and writing that CSR and then projecting the "prv"
and "v" bitfields into the correct locations for the virtual register.
