* Remove dependency on capstone for PowerPC disassembly #6292
* Add support for PowerPC VLE instruction set #6740
* Add support for paired-single instructions #6821
* Various post-merge fixes and tweaks to disassembly and lifting
* Removal of dependence on capstone for assembler's scoring mechanism (capstone currently disabled, but not removed from codebase yet)

Apparently the compiler on macOS is less strict about this change?

Also update minimum CMake version.

NOTE sections were being treated as loadable segments when they should be metadata-only. The NOTE section had the allocatable flag set. The program correctly checked for SHF_ALLOC but didn't exclude NOTE sections explicitly. NOTE sections consumed 0x50 bytes at the base address

The target of the bind opcode has its symbol applied when the dynamic
symbol table is parsed.
This was previously adding a symbol at the fixed-up address with the
name of the symbol being bound. This was resulting in dozens of
`_OBJC_CLASS_$_NSObject`, `_OBJC_METACLASS_$_NSObject`, and
`__objc_empty_cache` symbols being created: one for each `objc_class`
that referenced those symbols.

Amends calls to BNFreeString in kernel cache API that were causing `get_macho_header_for_address`, `get_macho_header_for_image`, `get_image_name_for_address`, and `get_name_for_address` to fail.
Fixes https://github.com/Vector35/binaryninja-api/issues/6855

- Removed last use of user object creation in objective-c
- Fixed function type info being omitted from certain images loaded automatically
- Add TODO about undo action in view init. This is not critical, just a non-actionable warning because of a design flaw
I will restate this again for anyone in the future, until the undo action system is thread-safe avoid calling it from any thread other than the main thread, it is very easy to deadlock or cause other issues. That goes for basically all user analysis object creation.

This occurred because prior to the change made in build `7484` we short-circuited when the pointer pointed to a read only segment, now that we consult the section the sections semantics were incorrect and failed, this fixes the dyld data sections to have correct semantics.

named workflow
Activities are registered with a `viewType` predicate to ensure they
only run in shared cache views.
Adding activities to `core.function.metaAnalysis` lets activities
registered by plug-ins run in the shared cache without the plug-ins
having to be aware of the shared cache.
Work towards #6779.

This disables the filter for already added images, there is another check when we go to apply so that it fails early but the real issue is the fact this happened at all.
Within the Objective-C processor there is a call to `BeginUndoActions` which calls `ExecuteOnMainThreadAndWait`, while the objective-c processor is holding the lock to the controller.
To fix this we really need to make the undo action system not call `ExecuteOnMainThreadAndWait` which is deadlock city, to do that really the only solution is to make the `UndoBuffer` thread-safe and remove the calls to execute undo related stuff on the main thread, this will make it so that when a call to `BeginUndoActions` there is no requirement to wait on pending undo actions as they are all submitted immediately.

Use mappingOffset as an upper bound for the header size, and avoid
reading any header fields from beyond that offset.

underlying VirtualMemory

8267ab475cb2ac82fd3724c009f21e8e30143f6b introduced a logic error in
VirtualMemoryReader::ReadPointer that caused VirtualMemoryReader to
attempt to read pointers from the wrong address, breaking parsing of
Objective-C metadata.

Still need to fix branch island images not being picked up

added in the background through the UI
We set some model data after the fact that didn't exist because the qt object was destructed on tab close.

We will have 2 live references in the DeleteController function, this warning does not need to be shown.

Simple change that means an image's dependencies can be loaded via the DSC triage view whether the primary image has already been loaded or not. Sometimes I've already loaded an image and then later on decide I want to load its dependencies. Currently there is no easy way to do that in the UI.

of the header
We did not truncate the buffer length when reading the header using the mappingOffset size, resulting in a buffer overflow.

file metadata destruction
Previously we would just let them continue to exist after view destruction, this is fine assuming we expect the user to be re-opening the same cache over and over, but
if a user wants to load a bunch of different caches they might want to evict the old file accessors so that COW pages are known to be evicted, along with other paged in memory.

Following the conversation in https://github.com/Vector35/binaryninja-api/issues/6631 we are going to make the edited alerts warnings and then also fix the warning showing on certain shared caches even when all entries are present.
|
|
1. Crash on kernel cache image load
2. Duplicate Load Image buttons in kernel cache view
3. Improper selection behavior in both views
4. Address column should no longer resize to be smaller than contents
5. Symbol tables should now be properly sortable
|
|
|
|
However the primary file will need to be selected each time you open, for that to be resolved we need to use project file UUID's or the cache entry UUID's themselves to traverse all project files
|
|
This commit addresses some of the issues regarding the retrieval of cache entries during view init, we now will try and store information in the database
about the given shared cache entries so that we can better alert the user to possible issues during the loading of saved shared cache databases. We also simplified
the logic so that the flow for retrieving the primary file cache is easier and users should be prompted when necessary to select the primary cache file if we cannot.
More errors will also be shown to provide the users with more information about the shared cache and what issues they might have. For example we will now try and warn the users
when they are opening a shared cache with less entries than what the shared cache reports having. We will also warn the users when opening a database if a previous secondary cache
file is no longer available.
In the future we can also utilize the shared cache UUID's for individual files to do a more aggressive search across directories in a project. This will make the file name lookup stuff
potentially unnecessary, at least when opening a database with all file UUID's stored.
|
|
The atlas files include section name info on images, its not helpful for us and skipping it altogether will remove an unneeded error related to parsing this other format
|
|
- Make `SharedCache::m_entries` a simple std::vector we never lookup based off the entry ID
- Remove some old comments
- Rename some old variables so that they are accurate
- Fix compiler warnings
- Remove some unneeded copying
