This has a couple of advantages:
* It makes it easier to add a catalyst version of these libraries (because it
becomes cumbersome to build for catalyst when the build rules assumes we're
building for both simulator and device).
* It makes it easier to create an xcframework of our libraries, because the
contents in an xcframework is split like this.
* [Foundation] Add an NSArray.FromNSObjects overload that can take an array of INativeObjects.
* [runtime] Use mono_array_setref instead of mono_array_set.
Otherwise the GC won't know about the assignment, and the assigned value can
be freed if it's no longer referenced anywhere else.
* [runtime] Throw a managed exception instead of trying to call a null function pointer if the runtime tries to call a function that has been linked away.
* [tests] Add new file for Xamarin.Mac tests.
* Direct people to file issues in github.
* Add support for delegates as return values in protocol members. Fixes#4102.
This required a few changes:
* The generator now emits the DelegateProxy attribute for property getters in
protocol interfaces.
* The generator now emits the DelegateProxy attribute in ProtocolMember
attributes (and the ProtocolMember attribute has been extended with
additional properties for this purpose).
* The generator now emits the BlockProxy attribute for the parameter in
property setters.
* The generator now emits the BlockProxy attribute in ProtocolMember
attributes for property setters.
* The static registrar now emits the metadata token for the
DelegateProxy.DelegateType property into the generated code so that the
DelegateProxy attribute itself isn't needed at runtime. This is required
when the dynamic registrar has been optimized away.
Fixes https://github.com/xamarin/xamarin-macios/issues/4102.
* [tests] Update MX4105 test to expect new warnings.
This test contains code that requires the dynamic registrar unless the code is
optimized, and it's only optimized if the assembly is linked, which only
happens if linking all assemblies.
So disable the test if dynamic registrar is removed (which happens when all
optimizations are enabled) and the assembly isn't linked.
Fixes https://github.com/xamarin/xamarin-macios/issues/4566.
* [tests] Determine at runtime instead of compile time whether LinkAll is enabled. Fixes#3812.
This way we can remove the LINKALL define, which also means nobody can forget
to define it when building using LinkAll.
https://github.com/xamarin/xamarin-macios/issues/3812
* [runtime] Don't throw exceptions when checking if a token reference exists (and not finding any). Fixes#3830.
It's not necessarily bad to not be able to find a token reference for a class:
in particular not if we're just checking if a token reference exists. In this
case, don't throw any exceptions, so that the fall-back code path (if no token
references were found) can execute properly.
This scenario occurs when all the following are true:
* The runtime runs into a native object that is exposed in managed as a protocol.
* The native type's managed type does not implement the protocol.
* The dynamic registrar is being used.
Fixes https://github.com/xamarin/xamarin-macios/issues/3830.
* [runtime] Don't lock while calling selectors that can up calling managed code. Fixes#3943.
Instead of locking the framework peer lock while we call release on dying
object, we just lock and then immediately unlock again before calling release.
This enforces an execution order that still strong enough to not run into race
conditions, while at the same time not running into deadlocks.
Fixes https://github.com/xamarin/xamarin-macios/issues/3943.
* Revert previous revert (9ba23946d1)
* Correctly fall back to Modern if tagless binding projects
* Rework binding tests to cover all supported configurations
* Add XM_FORCE_MSBUILD env variable for mmp/msbuild mac tests for easy local checking
Add support for blocks in static protocol members by adding another field to
the [ProtocolMember] attribute that specifies the block proxy type.
Fixes https://bugzilla.xamarin.com/show_bug.cgi?id=41226.
* [ObjCRuntime] Don't double-retain blocks.
First there was darkness; no blocks were retained.
Then came the light; and all blocks were retained [1]
Forever.
But all that once is, must one day not be,
and thus the light gave way to darkness,
and blocks were only retained as long as need be [2].
But before there was a balance, there was a crossroad.
In some places the light shone forever,
and all blocks were retained.
In other places there was a balance,
and the light shone only as long as needed.
A desire to unify arose.
Alas, it could not be.
It was a bright and sunny day
When a merge failed [3].
And all blocks were retained. Twice.
Once [here][4] and once [there][5].
For many years we could not see.
Until a dark and rainy night,
when an awareness arose.
And the desire to unify the balance could finally be fulfilled.

* [tests] Fix test builds.
* [monotouch-test] RegistrarTest.BlockCollection: allocate more and wait longer for the GC.
Allocate more objects and wait longer for the GC to run.
Hopefully fixes this problem:
[FAIL] RegistrarTest.BlockCollection : freed blocks
Expected: greater than 0
But was: 0
The blocks are freed if we just wait long enough... The problem is that we
don't want to wait very long (makes the tests slow to run), so try to speed
things up by allocating more.
- Fixes https://github.com/xamarin/xamarin-macios/issues/3608
- Refactor and clean up msbuild to be more consistent between binding and "normal" workloads
- Comment on the inconsistencies that are too large to fix in one PR
- Write some actual tests for binding projects to detect regressions
- Due to lack of redirect support these tests are only xbuild current, but I ran tests with msbuild to validate locally
* [static registrar] Optimize creation of delegates for blocks.
Optimize creation of delegates for blocks so that it doesn't require the
dynamic registrar.
This is done by getting the metadata token for the Create method that creates
the delegate, and embed that metadata token in the generated code from the
static registrar.
Also add tests, since this scenario was not covered by tests already.
* [mmptest] Fix test after recent changes.
* [test-libraries] Avoid duplicate symbols.
* [tests] Update according to changes.
The [Protocol] attributes the test checks for are not linked away in
monotouch-test (because monotouch-test only links SDK assemblies), but they
are linked away in link all, so adjust the test accordingly.
* [linker] Optimize calls to BlockLiteral.SetupBlock to inject the block signature.
Optimize calls to BlockLiteral.SetupBlock[Unsafe] to calculate the block
signature at build time, and inject it into the call site.
This makes block invocations 10-15x faster (I've added tests that asserts at
least an 8x increase).
It's also required in order to be able to remove the dynamic registrar code in
the future (since calculating the block signature at runtime requires the
dynamic registrar).
* [mtouch/mmp] Add support for reporting errors/warnings that point to the code line causing the error/warning.
Add support for reporting errors/warnings that point to the code line causing
the error/warning by adding ErrorHelper overloads that take the exact
instruction to report (previously we defaulted to the first line/instruction
in a method).
* [tests] Add support for asserting filename/linenumber in warning messages.
* Make all methods that manually create BlockLiterals optimizable.
* [tests] Create a BaseOptimizeGeneratedCodeTest test that's included in both XI's and XM's link all test.
* [tests] Add link all test (for both XI and XM) to test the BlockLiteral.SetupBlock optimization.
* [tests] Add mtouch/mmp tests for the BlockLiteral.SetupBlock optimization.
* [tests][linker] Make the base test class abstract, so tests in the base class aren't executed twice.
* [tests][linker] Don't execute linkall-only tests in linksdk.
The optimization tests only apply when the test assembly is linked, and that
only happens in linkall, so exclude those tests in linksdk.
* [tests][mmptest] Update test according to mmp changes.

* [tests][linker] Fix typo.

* [docs] mmp shows MM errors/warnings.
* [docs] Improve according to reviews.
* [tests] Fix merge failure causing test duplication.
* [tests] Build the native test library for macOS and create a binding project for it.
Also add the new binding project to the xammac and link all XM test projects,
which allows us to stop excluding tests that require the native library and
the corresponding bindings.
* [tests] Include more tests in xammac_tests.
* [tests] Correctly ignore the ObjC exception tests in release mode.
This also requires implementing the corresponding matrix (NMatrix4x3).
Fixes this xtro issue:
> !unknown-simd-type-in-signature! OpenTK.Matrix3 AVFoundation.AVCameraCalibrationData::get_GetIntrinsicMatrix(): the native signature has a simd type (matrix_float3x3), while the corresponding managed method is using an incorrect (non-simd) type.
* Rename them to be OpenTK.NMatrix# (instead of Simd.MatrixFloat#x#).
* Remove the Vector2 and Vector4 variants, we'll use the OpenTK types instead (but we'll keep the NVector3 variant, since it's not identical to the OpenTK version).
* Update the API to match their OpenTK counterparts better:
* NMatrix2 and NMatrix3 have a 0-based R#C# scheme for their fields.
* NMatrix4 has a 1-based M## scheme for its fields (i.e. no change).
[registrar] Support 'out' parameters from NULL pointers. Fixes#54919.
Native code doesn't have the 'out' and 'ref' distinction C# has, and passes
NULL around left and right.
So make sure the generated code from the static registrar doesn't write to such NULLs.
https://bugzilla.xamarin.com/show_bug.cgi?id=54919
Generate trampoline and registrar tests that tests if a return type requires objc_msgSend or objc_msgSend_stret.
Now it's much easier to test new return types (a single line of code), which
avoids a _lot_ of copy-pasting, and makes sure all the different variations
are tested properly.
These new tests found several bugs, which are fixed in subsequent commits.
* [tests] Remove Classic SDK tests.
* Remove XI/Classic support.
This also means we can remove support for the legacy registrars.
* [monotouch-test] Remove legacy registrar tests.
* [tests/mtouch] Remove Classic tests (and legacy registrar logic).
* [tests/scripted] Fix tests to reference Xamarin.iOS.dll.
Support binding NSObjects as IntPtr. This is usually not
a problem, because when we fetch the ObjC signature for a
method, we usually get the signature as exported by us,
(in which case a parameter bound as 'IntPtr' would be treated
as 'void *' in the dynamic registrar) *except* when the
selector corresponds with a protocol the type implements,
in which case we get the signature as defined in the protocol.
