* [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
reference:
https://github.com/xamarin/xamarin-macios/issues/3200
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.
* [mtouch] Improve how we make sure native symbols aren't stripped away. Fixes#51710 and #54417.
* Refactor required symbol collection to store more information about each
symbol (field, function, Objective-C class), and in general make the code
more straight forward.
* Implement support for generating source code that references these symbols,
and do this whenever we can't ask the native linker to keep these symbols
(when using bitcode). Additionally make it possible to do this manually, so
that the source code can be generated for non-bitcode platforms too (which
is useful if the number of symbols is enormous, in which case we might
surpass the maximum command-line length).
* Also make it possible to completely ignore native symbols, or ignore them on
a per-symbol basis. This provides a fallback for users if we get something
right and we try to preserve something that shouldn't be preserved (for
instance if it doesn't exist), and the user ends up with unfixable linker
errors.
* Don't collect Objective-C classes unless they're in an assembly with
LinkWith attributes. We don't need to preserve Objective-C classes in any
other circumstances.
* Implement everything for both Xamarin.iOS and Xamarin.Mac, and share the
code between them.
* Remove previous workaround for bug #51710, since it's no longer needed.
* Add tests.
https://bugzilla.xamarin.com/show_bug.cgi?id=54417https://bugzilla.xamarin.com/show_bug.cgi?id=51710
* [mtouch] Make sure to only keep symbols from the current app when code sharing.
This fixes a build problem with the interdependent-binding-projects test when
testing in Today Extension mode.

Some of the above types from System.dll implemented ObjCRuntime.INativeObject
(from System.dll), which our linker detected as implementing
ObjCRuntime.INativeObject (from Xamarin.iOS.dll), so these types were treated
as custom NSObject subclasses, and the MarkNSObjects linker step would mark
them (which would in turn cause all the other types in the list to be marked).
With that change, these types now implement ObjCRuntimeInternal.INativeObject,
and the linker does not treat them as custom NSObject subclasses anymore.
I think the new behavior is correct: these types do not actually inherit from
the real NSObject/INativeObject, so the linker should not treat them as such.
This may run into different bugs because the linker might now remove more
stuff than before, but that would be a different issue.
This means that the fix is to modify these tests accordingly.

* Bump mono to latest.
* Fix merge conflict that was missed
* [mtouch] Renumber new error which clashes with an existing error number in master.
* [mtouch] Allow code sharing assemblies from multiple locations if they're identical. Fixes#56498.
We disallow code sharing when the same assembly (based on name) is referenced
from multiple paths, but poke a hole in this logic by allowing the same
assembly from multiple paths when those assemblies are 100% identical, since
that should be 100% safe.
https://bugzilla.xamarin.com/show_bug.cgi?id=56498
* [tests] Comment out assert that asserts due to another bug.
If both an extension and the container app (or multiple extensions) reference
the same binding assembly for a framework, then we'd error out with an
internal error when trying to copy the framework from both locations to the
container app.
So instead detect when we're trying to copy multiple identical (by comparing
the on-disk contents) frameworks, and only copy one of them.
We'll still show an error if the frameworks are different, but now a nice
MT1035 error with a proper error description instead of an internal error.
https://bugzilla.xamarin.com/show_bug.cgi?id=56635
Replace https://github.com/xamarin/xamarin-macios/pull/1973 expect that
the test parts are still needed.
* Add XM SDK + LinkSkip test
* [macos] Add platform linking support to msbuild
* [macos] Add full SDK test
* [macios] Diable classic from using linkplatform
- Extended test infrastructure change to allow classic projects that include bundling
- Setting linkplatform in MonoBundlingExtraArgs since we don't even read project setting LinkMode - Platform for classic
- Actually enable hybrid AOT by adding argument in right location
- Hybrid AOT and stripping does not play well currently with partial AOT
- Fix AOT makefile to work with nuget nunit
- https://bugzilla.xamarin.com/show_bug.cgi?id=55041
It does not make sense to support incremental builds for the simulator (since
no AOT compilation is done), it just makes the test matrix more complicated.
So simplify things by removing support for incremental builds.
We also ignore any (other) --assembly-build-target arguments, because building
to frameworks doesn't make sense either in the simulator.
https://bugzilla.xamarin.com/show_bug.cgi?id=55712
We do support the use of [Async] on methods that do not return void,
we generate an overload with am out parameter to retrieve the returned value

var tcs = new TaskCompletionSource<bool> ();
var result = BarString(arg1, (obj_) => {
if (obj_ != null)
tcs.SetException (new NSErrorException(obj_));
else
tcs.SetResult (true);
});
return tcs.Task;
}
[CompilerGenerated]
public unsafe virtual Task BarStringAsync (int arg1, out string result)
{
var tcs = new TaskCompletionSource<bool> ();
result = BarString(arg1, (obj_) => {
if (obj_ != null)
tcs.SetException (new NSErrorException(obj_));
else
tcs.SetResult (true);
});
return tcs.Task;
}
```
