* [runtime] Add an inner exception parameter to Runtime.CreateProductException.
This allows us to simplify code by using inner (and outer) exceptions as
a means to provide information instead of passing extra information
around in order to create decent exceptions.
One example is how we pass the selector and method name to the method
that converts from a native id to a managed NSObject instance: passing
this information is not necessary anymore if we can use two exceptions,
one for the failure to convert from an id to a NSObject instance,
wrapped in a second that tells which method/selector call ran into this
conversion problem.
* [runtime] Throw better exceptions when the dynamic registrar can't marshal something.
* [runtime] Throw a better exception when something goes wrong when trying to marshal a return value.
* [runtime] Use inner exceptions to convey failure information instead of trying to create a single exception with all we know.
* Fix merge problem.
This also centralize other interpreter checks and options in the same
location (making it easier to read / update).
* Warn and switch the REPL if the interpreter is enabled on simulator
Why ? It's confusing to build the same code using different options for
simulator and devices. This is what happens if you try to use features
like `dynamic` or `System.Reflection.Emit`.
So instead of an error, we warn that the interpreter is not supported
and switch to the existing REPL mode.
The JIT remains the only option for the simulator but it allows testing
features without a device.
* Fail early if the interpreter is used on 32bits [1]
The current interpreter only works on 64 bits (so ARM64). However the
error won't be reported, back to the developer, until deployment time.
This temporary [1] fix spot the condition very early and report an error
```
error MT0099 : Internal error : The interpreter is currently only available for 64 bits.
```
instead of the current one at deploy time
```
IncorrectArchitecture: Failed to find matching arch for 32-bit Mach-O input file /private/var/installd/Library/Caches/com.apple.mobile.installd.staging/temp.tNKDlx/extracted/X.app/X

* [tests] Fix/renumbered MT0138
The test was using simulator + interpreter which is not _really_
possible, we use REPL in that case - so we're now checking if
assemblies were specified with `--interpreter` to cover both cases.
Also 0138 was already used by `mmp` and the warning was **not**
registered or documented in the errors documents. To avoid
confusion it has been renumbered to 0142 and documented.
document it and adjust the optimization tests.
This allows the optimization to be:
* disabled (if ever needed) on fully AOT'ed applications
* re-enabled for the interpreter (at your own risk)
* MachO.cs: Support reading LC_BUILD_VERSION
Newer SDKs set this instead of LC_VERSION_MIN_*
* MachO.cs: Add support for reading Mach-O files inside ar archives.
* [tests] Augment ProductTests.MinOSVersion to test static libraries as well.
* Adjust enum field names to match our naming scheme.
* Add a Runtime.IsARM64CallingConvention property.
Determining whether we should use the ARM64 calling convention in P/Invokes
gets more complicated with ARM64_32 (which for our purposes is a 32-bit
architecture).
So add a property on the Runtime class to avoid code duplication, and teach
the linker to optimize any calls to this property to a constant value whenever
possible (and the method is marked as optimizable).
Also change our code to use this new property, and make the corresponding
methods optimizable.
Some shuffling in mmp was required, which meant a little bit more code is now
shared between mtouch and mmp.
* Coding style.
* Test tweaks.
* Improve comment.
* Document new optimization
* Move ILReader to shared linker test code location.
* Disable inlining on armv7k.
* Change IsARM64CallingConvention to a read-only field.
We can give the AOT compiler a constant value for a read-only field, so that
the AOT compiler optimizes away the call to the field by using the constant
value.
This commit does not implement this change for the AOT compiler, but using a
read-only field makes it easy to implement it in the future.
* [linker] Remove non-bitcode compatible code, and show a warning.
Remove code not currently compatible with bitcode and replace it with an
exception instead (otherwise we'll assert at runtime).
Also show a warning when we detect this.
This is quite helpful when looking at watch device test runs to filter out
failures we already know about.
This fixes point #2 in #4763.
* Improve documentation.
* Simplify linker code by using a substep.
* Fix whitespace issues.
* Improve reporting.
* Add support for reporting more than one MT2105 at the same time when making
the errors instead of warnings.
* Only report MT2105 for methods that haven't been linked away.
* Format the error message nicer for properties.
* Tweak a bit for warning tests to pass.
* Use ExceptionalSubStep to provide better error information.
* Adjust where linker warnings/errors are reported from to avoid a NullReferenceException.
* Make PreserveSmartEnumConversionsSubStep use error codes that are not
already used elsewhere: this isn't obvious at first, but all
ExceptionalSubStep errors use a range of error numbers (10 numbers from NNN0
to NNN9), so we need to reserve that entire range. In this case there were
other errors using some of the numbers of the range for PreserveSmartEnumConversionsSubStep.
* Make sure there are anchor links for all the variations of each ExceptionalSubStep error.
The `[NullAllowed]` attribute should not be allowed on methods but it
could break existing binding projects.
Historically it was used on property setters. However using the attribute
on _other_ methods can be misleading, e.g. should it apply to all
parameters, the return value... and its presence/action can be
misinterpreted in code reviews leading to binding bugs.

Fixesxamarin/xamarin-macios#4107
We currently generate invalid registrar code when we get invalid input
in 'Adopts' attribute, this can happen because 'Adopts' can take a
plain string. We now generate a better error MT4177 instead of
generating invalid registrar.m/h code.
Instead of a generic `MT0000` caused by an exception reading the magic
numbers of the binary framework file.
This was caused be uncompressing an archive, with a symlink, into a
file system that does not support symlinks (on Windows).
ref: https://github.com/xamarin/xamarin-macios/issues/5028
We don't need to use a custom mono to run the generator anymore, so stop doing
it.
Unfortunately we can't remove the custom mono, since we're now using it for
another purpose (AOT-compiling XM apps).
Fixes https://github.com/xamarin/xamarin-macios/issues/3675.
* [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.
* [mtouch] Show warnings when we can't find referenced assemblies.
This would have helped track down #4235.
* Improve MT0137 warning to indicate the type of the attribute causing the warning.
* Convert it into a MM8027/MT8027 error (with documentation).
* Add information about the selector and managed method that triggered the error.
Now the problem reported in issue #4254 shows up as:
> ObjCRuntime.RuntimeException: Failed to marshal the Objective-C object 0x7f8080412810 (type: UIView). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'UIKit.UIView&' does not have a constructor that takes one IntPtr argument).
> Additional information:
> Selector: popoverController:willRepositionPopoverToRect:inView:
> Method: UIKit.UIPopoverController+_UIPopoverControllerDelegate.WillReposition(UIKit.UIPopoverController, CoreGraphics.CGRect ByRef, UIKit.UIView ByRef)
instead of just:
> ObjCRuntime.RuntimeException: Failed to marshal the Objective-C object 0x7f8080412810 (type: UIView). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'UIKit.UIView&' does not have a constructor that takes one IntPtr argument).
which makes it much easier to understand, track down, and fix/work around,
both for customers and ourselves.
* [mtouch/mmp] Handle invalid types in BlockProxy attributes better. Fixes#4072.
BlockProxy attributes may have types we don't expect, so handle those cases
gracefully by showing a warning when we encounter them:
testApp.cs(11): warning MT4175: The parameter 'completionHandler' in the method 'Issue4072Session.CreateDataTask(Foundation.NSUrl,Foundation.NSUrlSessionResponse)' has an invalid BlockProxy attribute (the type passed to the attribute does not have a 'Create' method).
instead of an ugly MT0000:

The main cause of the warning: "warning MSB6002: The command-line for the 'MTouch' task is too long" was the number of references that can be passed to `mtouch`.
Now all the arguments are written in a response file which in turn is passed to `mtouch`.
- Fixes bug #56501: MSB6002 command-line for MTouch task is too long, > 32000 characters
(https://bugzilla.xamarin.com/show_bug.cgi?id=56501)
- The response file is created in the device specific folder, as `response-file.rsp`. It is re-created every time.
- Added an msbuild test to ensure the response file is created by `GenerateCommandLineCommands` and that it includes all the references.
- Introduce `AddLine` and `AddQuotedLine` which we use to populate the response file (and go to the next line).
- Move to C# 7 syntax for string replacement.
- Update all tests in `MTouchTaskTests` to use the response file since the arguments are no longer passed directly to `mtouch`.
- Update MT0018's documentation for response files.

Implement support for optimizing away the dynamic registrar.
* Add a new property (Runtime.DynamicRegistrationSupported) that indicates at
runtime whether dynamic registration is available.
* Check this new property whenever we need dynamic registration.
* Add an optimization to mtouch/mmp that detects whether dynamic registration
is required, and if not, changes Runtime.DynamicRegistrationSupported to
return false.
* Add an optimization to mtouch/mmp that inlines
Runtime.DynamicRegistrationSupported as a constant value.
The end result is that the linker will link away the dynamic registrar if
mtouch/mmp detects that it's not needed.

Improved linker to:
* Not mark protocol interfaces by the mere virtue of having a type that
implements them. This is implemented by not marking protocol interfaces when
they're implementing a class, but instead when a method implementation is
found to implement a method from a protocol interface.
* Mark the wrapper type for protocols (this allows us to remove the Protocol
attribute, since that's the link between the protocol and its wrapper type).
* Remove the [Protocol], [ProtocolMember] and [Adopts] attributes.
The static registrar still needs some of the information linked away, so a few
changes are required to make it available post linker.
Generate table of protocols and their corresponding wrapper type in the static
registrar, so that we don't have to look for this information using the
dynamic registrar at runtime.
* [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.

`WrapAttribute` can now be used in property getters and setters,

smart enums, consider the following API definition:
```csharp
// Smart enum.
enum PersonRelationship {
[Field (null)]
None,
[Field ("FMFather", "__Internal")]
Father,
[Field ("FMMother", "__Internal")]
Mother
}
```
```csharp
// Property definition.
[Export ("presenceType")]
NSString _PresenceType { get; set; }
PersonRelationship PresenceType {
[Wrap ("PersonRelationshipExtensions.GetValue (_PresenceType)")]
get;
[Wrap ("_PresenceType = value.GetConstant ()")]
set;
}
```
* Fix Feedback
* Fix doc error
* Update error message
* [ObjCRuntime] Add a BindingImplAttribute.
* [linker] Make ProviderToString an extension method on ICustomAttributeProvider to make it more discoverable.
* [generator] Use [BindingImpl] instead of [CompilerGenerated].
The entire diff is big (89MB), so it can't be gisted. However, most of it is
either removal of `using System.Runtime.CompilerServices;` or the change from
`[CompilerGenerated]` to `[BindingImpl (...)]` like this:
https://gist.github.com/rolfbjarne/8bfda3ed37b956d0342a1c1e9b079244
If I remove those parts of the diff, there's nothing significant left:
https://gist.github.com/rolfbjarne/4156164d6bdb1376366200394eb8a091
* [linker] Teach the linker about the new [BindingImpl] attribute.
In addition to the existing logic where the linker would optimize some
[CompilerGenerated] code (sometimes with additional requirements), it will now
also optimize all [BindingImpl (Optimizable)] code (without any additional
requirements).
* [tests] Add tests to make sure [BindingImpl (Optimizable)] works as expected.
* [linker] Check for [BindingImpl] before [CompilerGenerated] and stop checking for [CompilerGenerated] in XAMCORE_4_0.
Check for [BindingImpl] before checking for [CompilerGenerated], since the
former is more common.
Also stop checking for [CompilerGenerated] (at least to mean that code is
optimizable) in our next non-compatible evolutionary leap (XAMCORE_4_0):
* [introspection] Impl a better typo check.
* [mtouch/mmp] Give users more control over optimizations, and share more code between mtouch and mmp.
1. Add an --optimize flag to mtouch/mmp that allows users to select which
optimizations to apply (or not). This makes it easier to add future
optimizations, and allow users to disable any optimization that causes
problems without having to disable many other features.
2. Share as much optimization code as possible between mtouch and mmp. This
immediately gives a benefit to mmp, which has three new optimizations only
mtouch had: NSObject.IsDirectBinding inlining, IntPtr.Size inlining and
dead code elimination.
This results in ~6kb of disk space saved for a linked Xamarin.Mac app:
* link sdk: [Debug][1], [Release][2]
* link all: [Debug][3], [Release][4]
Testing also verifies that monotouchtest ([Debug][5], [Release][6]) has not
changed size at all, which means that no default optimizations have changed
inadvertedly.

* [tools] Don't enable the IsDirectBinding optimization by default for Xamarin.Mac apps, it's not safe.
* Fix whitespace issues.
* [doc] Document optimizations.
* Officially support optimizations by adding them to the Versions.plist.
* [linker] Improve IntPtr.Size inliner + dead code eliminatior and add tests.
* Properly handle operands for the ldc_i4_s instruction (they're sbyte).
* Fix less-than condition to actually do a less-than comparison.
* Make sure to look up the bitness in the Target, not the Application, since
the Application's value will be incorrect when building fat apps (both
Is32Build and Is64Build will be true).
* Remove unnecessary checks for the IntPtr.Size inliner: this optimization
does not depend on other instructions than the IntPtr.get_Size call, so
remove the checks that verify surrounding instructions. This makes the
IntPtr.Size inliner kick in in more scenarios (such as the new tests).
* Add tests.
* [tests] Add mmp tests for optimizations.
* [tests] Fix XM optimization tests.
* [tests] Fix test build error.

This enables ImageRepresentation strong dictionary helpers.
--- A note about WrapAttribute
Whenever we use the `WrapAttribute` inside a `Category` we need to
include the `This` parameter as the first argument inside the Wrap
signature, like the following example:
```csharp
[Wrap ("WriteTiffRepresentation (This, image, url, format, colorSpace, options?.Dictionary, out error)")]
bool WriteTiffRepresentation (CIImage image, NSUrl url, CIFormat format, CGColorSpace colorSpace, CIImageRepresentationOptions options, out NSError error);
```
* [mtouch][mmp] Report invalid debug symbols files. Fixes#3200
Try to read the assembly with symbols and, if that fails, warn and
fallback to loading them without symbols.
This fixes cases were it's not easy to update or delete (e.g. nuget)
bad symbols files - so this cannot be an error without causing a lot
of pain.
However it needs to be reported, otherwise it wont be fixed (by the
publisher) and it can limit the debugability of the application and
the usefulness of the stacktraces.
Finally merge most of the resolver's code between mtouch and mmp so
we don't have to fix such issue twice anymore.
note: this needs to be slightly updated once we get a version of cecil
that can give us a more precise error message.
Also bring Rolf's tests from
https://github.com/xamarin/xamarin-macios/pull/3079

When a method signature contains any ref/out parameters
it is a hint that this method is not a candidate to be
used with [Async] we now error BI1062 in the generator.
The reason of an error instead of a warning is that we
currently generate not compilable code when ref/out is
used on the method signature or in the signature of the
delegate (completion handler), it is very unlikely we are
breaking someone now that we emit an error instead of broken
code.
* Fix Anchor and Clarify the addition of BI1117 Warning into docs/website/generator-errors.md
BI1117 Warning documentation was missing from docs/website/generator-errors.md
so I added it.
- Add XIA0006: HttpClientAvoidManaged.
- Add documentation on how the rules work and how to activate them.
Also mention that they need to be ran on each active configuration.
- Bump maccore to include XIA 0006.
* [generator] Improve BI1014 - include name of unsupported field and update valid types on docs, fixes bug 57094.
https://bugzilla.xamarin.com/show_bug.cgi?id=57094
* Implement feedback
* fix error message
* More feedback
Detect MT1111 from mlaunch (which means mlaunch won't wait for the app to
exit), and instead use test run completion to determine test completion.
The main drawback is that if the test app crashes, it won't be detected (the
test run will time out, and reported as such), but it's still an improvement
over the current behavior (the tests may complete successfully, and still be
reported as timed out).
This also requires bumping maccore to get an updated mlaunch (one that reports
MT1111).
It does not make sense to create Xamarin.iOS projects that don't reference
Xamarin.iOS.dll, so make this an explicit error.
This fixes a NullReferenceException which could (when building for device, or
when not using simlauncher) occur, and instead shows the MT0123 error.

Bug #59570 was a dupe of #58063 but was harder (than it should be) to
diagnose because the error did not point out which assembly had the
issue (requiring a whole, large, customer solution to confirm).
This adds a new MT2103 error which points to the assembly that could
not be read.
E.g. VSfM will now show
> Error MT2103: Error processing assembly 'Shim, Version=2.0.1.0, Culture=neutral, PublicKeyToken=c55ec16d10c4b366': System.NullReferenceException: Object reference not set to an instance of an object (MT2103) (...)

* [mtouch/mmp] Downgrade MT0123 to a verbose log statement instead.
It's unlikely to be useful for normal people who've just set LANG for whatever
unrelated reason.
If it's needed to diagnose failures, it'll still show up in verbose logs.
* [docs] Remove MT0123, it's no longer being used, and we never released a version that used it either.
* [tests][mtouch] Update tests according to code changes (MT0123 removal).
* [mtouch/mmp] Set CultureInfo.CurrentCulture according to LANG.
This makes it easier to run mtouch/mmp under different locales when testing.
Unfortunately mono checks the system locale before checking LANG, which means
that there's no built-in way in macOS/mono to specify the current locale
without changing the system locale.
* [mtouch] Print verbosity using an invariant culture. Fixes#58849.
https://bugzilla.xamarin.com/show_bug.cgi?id=58849
* [mtouch/mmp] Fix error code.
* [mtouch/mmp] Log/warn when we set the current language.
* [mtouch] Don't allow building for 32-bit when deployment target is >= 11. Fixes#57966.
Also bump maccore to get an mlaunch error for launching a 32-bit app in a 64-bit-only simulator.
https://bugzilla.xamarin.com/show_bug.cgi?id=57966
* [tests][msbuild] Make sure all Info.plists have deployment targets.
Otherwise we get different behavior (32-bit allowed or not) depending on which
Xcode is used to build.
* [mtouch] Default to 64-bit arch if not specified and targeting iOS 11+.
* [tests] Tweak tests to either specify a deployment target < 11 or not build a 32-bit arch.
