This optimization can be enabled when it's not possible to use the
managed linker (e.g. **Don't link**) or when the managed linker cannot
remove references to deprecated types that would cause an application
to be rejected by Apple.
References to the existing types will be renamed, e.g. `UIWebView` to
`DeprecatedWebView`, in every assemblies.
The type definition is also renamed (for validity) and all custom
attributes on the types and their members will be removed.
Code inside the members will be replaced with a
`throw new NotSupportedException ();`.
The msbuild test app `MyReleaseBuild` has been updated to test that the
optimization is working as expected (device builds are slow so reusing
this test has little impact in test time).
Basically the test ensure that `UIWebView` is used and cannot be removed
by the compiler (optimization) or the managed linker (since it's
referenced). Since the optimization is enabled then we can `grep` then
final `.app` directory to ensure there's no mention of `UIWebView` inside
any of the files that would be submitted.
The application can be run, by itself, and will turn green if OK, red if
`DeprecatedWebView` can't be found (skeleton replacement for `UIWebView`)
or orange if a `NotSupportedException` is thrown.
Finally introspection tests have been updated to skip over the deprecated
(and renamed) types. It should not be an issue right now, since this
optimization is not enabled by default, but it made testing easier.
Using this option it's possible to test for the presence of a type
reference in both pre-linked and post-linked assemblies.
This makes it possible to detect if
* a 3rd party assemblies are using some specific type you would like to avoid;
* a type reference has been removed during the build (e.g. linker)
Notes:
* Custom attributes are encoded differently and not included in the assembly type references metadata.
* Assembly that define a type `X` do not have a reference (but the definition) of the type (and won't be reported).
If either the pre or post-linked warnings are not useful then it's possible
to add `-nowarn:150x` to exclude the results.
E.g.
* `-nowarn:1502` would not report references in pre-linked assemblies;
* `-nowarn:1503` would not report references in post-linked assemblies;
Finally `-warnaserror:150x` can be used to stop a build that would not
satisfy either the pre or post-linked condition.
* `-warnaserror:1502` would not report references in pre-linked assemblies;
* `-warnaserror:1503` would not report references in post-linked assemblies;
_side note_ this was first done on `d16-6` to ease backports as `master`
has multiple changes for localization. A similar PR will be done for
`master` once merged.

* [mmp] Don't ignore failures to execute pkg-config and simplify/improve logic.

* Extract logic to execute pkg-config into its own function.
* Simplify code slightly.
* [mmp] Remove the MM5301 error message.
It's never used in mmp, and the same error code is already used in mtouch.
This makes the `--time` options more useful to see inside the linker's
pipeline steps.
This was used only in `mtouch` before (and missed some steps [1]).
Now it's shared between both tools.

When building extensions, we first store all the mtouch arguments in a file
when msbuild builds the extension, and then when msbuild builds the main
project, we load those arguments again and actually build the extension at the
same time as we build the main app.
As such, it's important to make sure that when we reload the extension
arguments we end up with the exact same build configuration as the first time.
Unfortunately that was not the case regarding the interpreter: we
automatically set the 'EnableRepl' value in Main according to whether the
interpreter was enabled or not, but Main is not called after re-loading the
arguments when building extensions.
Fix this by moving the logic that automatically sets 'EnableRepl' to somewhere
that is executed when re-loading arguments when building extensions.

CoreFX uses a completely new `HttpClientHandler` implementation called `SocketsHttpHandler`,
which you can find at https://github.com/dotnet/corefx/tree/release/3.0/src/System.Net.Http/src/System/Net/Http/SocketsHttpHandler.
Since this is not based on the web stack anymore, it does not use any of the related APIs such
as `ServicePointManager` or `WebException`.
There is a new API called `HttpClientHandler.ServerCertificateCustomValidationCallback`.
- https://docs.microsoft.com/en-us/dotnet/api/system.net.http.httpclienthandler.servercertificatecustomvalidationcallback?view=netframework-4.8

- c1778515a3/src/System.Net.Http/src/System/Net/Http/HttpClientHandler.Windows.cs (L383)
The `ServicePointManager.ServerCertificateValidationCallback` is no longer invoked and on
certificate validation failure, `AuthenticationException` (from `System.Security.Authentication`)
is thrown instead of `WebException`.
At the moment, the `NSUrlSessionHandler` still uses it's own validation callback and also still
throws `WebException` on failure; we should probably look into making this consistent with the
other handlers.
* `HttpContent.SerializeToStreamAsync()` is now `protected` (changed from `protected internal`).
- src/Foundation/NSUrlSessionHandler.cs: changed overload accordingly.
- src/System.Net.Http/CFContentStream.cs: likewise.
* `HttpHeaders.GetKnownHeaderKind()` is an internal Mono API.
There is a new internal API called `System.Net.Http.PlatformHelper.IsContentHeader(key)`
which exists in both the old as well as the new implementation.
The correct way of doing it with the CoreFX handler is
`HeaderDescriptor.TryGet (key, out var descriptor) && descriptor.HeaderType == HttpHeaderType.Content`
* `HttpClientHandler.MaxRequestContentBufferSize` is now longer supported, you can set it to
any non-negative value, the getter will always return 0.

This is already compiled as ObjC++ but this gives an additional (and
required) hint to some tools that it is Objective C++ code.
This avoid a lot of build errors (under static analysis tools),
most of them not really helpful (a trait shared with many C++ compiler
warnings and errors) except for this one:
```
error: invalid argument ‘-std=c++14’ not allowed with ‘Objective-C’
```
* Implement a different escaping/quoting algorithm for arguments to System.Diagnostics.Process.
mono changed how quotes should be escaped when passed to
System.Diagnostic.Process, so we need to change accordingly.
The main difference is that single quotes don't have to be escaped anymore.
This solves problems like this:

* Rework process arguments to pass arrays/lists around instead of quoted strings.
And then only convert to a string at the very end when we create the Process
instance.
In the future there will be a ProcessStartInfo.ArgumentList property we can
use to give the original array/list of arguments directly to the BCL so that
we can avoid quoting at all. These changes gets us almost all the way there
already (except that the ArgumentList property isn't available quite yet).
We also have to bump to target framework version v4.7.2 from v4.5 in several
places because of 'Array.Empty<T> ()' which is now used in more places.
* Parse linker flags from LinkWith attributes.
* [sampletester] Bump to v4.7.2 for Array.Empty<T> ().
* Fix typo.
* Rename GetVerbosity -> AddVerbosity.
* Remove unnecessary string interpolation.
* Remove unused variable.
* [mtouch] Simplify code a bit.
* Use implicitly typed arrays.
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.
Tweak the watchOS architecture test to build for bitcode when building with
llvm, since that's what's usually done.
Also tweak the MT0145 error message a bit.
Fixes https://github.com/xamarin/maccore/issues/1994.
* [builds] add arm64_32 cross compiler
* [mtouch] force --interpreter on arm64_32 debug mode build
* [mtouch] include debug check for arm64_32 and reflect error codes in documentation
We ship a default, pre-built, simlauncher for iOS simulator applications.
This speeds up compilation for the default (non linked) simulator builds
quite a lot (no call to `clang` is needed). However it force us to keep
track of frameworks manually - `mtouch` can track them but requires
calling clang/ld to finish things up (killing the optimization).
It's easy to forget some (new) frameworks since they can be loaded
dynamically (on demand) _most_ of the time. Sadly there are a few cases
where doing so cause (hard to diagnose) problems - so we can't depend
on them being loaded, correctly for us.
The new test case loads the `otool -L` output (make when we build
simlauncher[32|64]-sgen) and compares it with mtouch's GetFramework
logic *and* with our namespaces (which is pretty close, with a few
exceptions, to the framework names). This will make it harder to
forget [weak] frameworks when adding new bindings :)
Fixes https://github.com/xamarin/xamarin-macios/issues/6951
* Add a dummy x86_64 slice to all our native libraries that don't have one. (#6848)
Apple's notarization tool has a bug where they incorrectly flag Mach-O
binaries without an x86_64 slice, so make sure all our libraries have one.
* Jenkinsfile notarization (#6869)
* Add in notarization script for xamarin.mac/xamarin.iOS
* Flatten the list to get rid of the braces
* Add in keychain password
* Add login.keychain back in to access codesigning certificates
* Always sign pkgs, upload notarized copies
* Enable ios notarization and make notarized pkgs public
* Make notarization non-fatal
* Publish GH statuses for notarized PKGs
* Don't forget to declare URI variables for notarized pkgs
* report proper package links
* [jenkins] Improve package reporting.
* Use dummy function name which our tests won't complain about.
* Build native code with -std=c++14.
Apple's headers now require -std=c++14 to compile their headers in C++ mode.
This fixes a compile error that would occur with the PhotosUI framework when
compiling code for C++.
* [mmp] Use -std=c++14 when compiling.
* Fix command line output.
* [mmp] Add all source files at the end, so they all get the -x clang argument applied.
* Limit when using c++14 in mtouch according to language.
Also limit the output from the native compiler, so that we don't overload the
IDEs with output if the native compiler produces tens of thousands of errors.
Fixes https://github.com/xamarin/xamarin-macios/issues/6526.
* [WatchKit] Remove this framework for iOS while keeping backwards compatibility. Fixes#6492.
* Copy all generated sources and modify them to throw PlatformNotSupported exceptions.
* Adjust some existing source code to also throw PlatformNotSupported exceptions.
* Sprinkle Obsolete attributes generously.
* Stop generating code for the WatchKit framework for iOS.
Fixes https://github.com/xamarin/xamarin-macios/issues/6492.
* [introspection] Adjust test.
* [mtouch] Don't link with WatchKit, and show a warning if we detect code that want to use WatchKit.
* [xtro] Remove WatchKit for iOS.
* [introspection] Don't check obsoleted NSString fields for null.
There's probably a reason the field was obsoleted.
* [introspection] Add exception for the WatchKit framework.
* [xtro] Ignore obsolete enums.
There's probably a reason they're obsoleted.
In particular it solves a confusion between WKWebKit.WKErrorCode and
WatchKit.WKErrorCode: for iOS, the latter is obsoleted, and this way we always
process the former instead.
* [mtouch] Adjust wording for MT4178 to be more accurate.
* [WatchKit] Make more API obsolete/hidden.
Two classes managed to slip past the first time.
* [tests] Adjust test after WatchKit removal.
* Use the commonly used casing for `MSBuildSDKsPath` property
Handle "incorrectly" cased msbuild property names
msbuild property names are case insensitive. While generating the custom
app.config, in `SetToolsetProperty(..)` we try to update the property if
it already exists. But the name lookup was case sensitive, thus causing
the lookup to fail, resulting in two entries for the same property name
differing only in case. Eg. `MSBuildSDKsPath` vs `MSBuildSdksPath`.
* [mtouch] Whitelist new Brotli native symbols in Xamarin.Tests.Misc.PublicSymbols test
* [mtouch] Better assert in NoLLVMFailuresInWatchOS() test
We'd list the "LLVM failed" messages before even though the AOT might've crashed and the list is meaningless. Assert the exit code before that.
* [mtouch] Use new LLVM even for 32bit targets
See https://github.com/mono/mono/issues/14841 and https://github.com/mono/mono/issues/9621
* [mtouch] Work around slow LLVM in "don't link" test

* Remove useless conditional
* Remove LLVM36 from Makefile
* [watch4] set right min version for arm64_32 based watch devices (#6307)
Fixes the confusion around `libmono-native*` (see for example ce5ba1e41d (commitcomment-33834491) ) when building with `MONO_BUILD_FROM_SOURCE=1`.
* reflect watchos64_32_version_min change from mono sdk
* Move mono hash info to mk/mono.mk so that existing scripts work.
* Add Makefile dependency on mono.mk where necessary
With 3e7bc29ade the Mono hash was moved from Make.config to mono.mk.
We need to add a Makefile dependency on this file wherever Make.config was used to track a Mono dependency.
* [tests] Copy mk/mono.mk to the XM test package.
* [tests] Update minOS version test after consolidating min watchOS versions everywhere.

This allows the optimization to be disabled in cases where one, or
many, a custom attribute(s) are required by the application at runtime.
While not ideal disabling this single step is much better than disabling
linking for the whole application.
A better approach is described in https://github.com/xamarin/xamarin-macios/issues/6048
but this configuration optimization makes sense independently of it.

According to Rolf it's fine to always add since the native linker will
figure out if it's really needed and so customers don't need to do
anything when using -all_load.
Mono started using System.IO.File from CoreFX and it has a different
behavior for File.Copy() when the target is a directory:
It just puts the file into the directory instead of raising an exception.
In order to fix the MT1015 test we just check ourselves whether the target
is a directory.
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.
In both cases we use a different binaries for a few assemblies. They
include support for SRE and a few other things that are not normally
usable on iOS. That's totally fine and not something that can be fixed
(unless you stop using the feature). So this PR simply ignore that
specific case so we don't warn about things that can't be changed (and
are not a problem)
E.g.
```

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)
* We only need to do a runtime check on watchOS.
* On watchOS assume we're on a ARM64-based CPU as long as we're not on a
ARMv7k CPU.
Fixes an issue where we failed to detect a 64-bit iOS CPU as ARM64-based (in
particular iPhone X's ARM64v8).
The Mono AOT compiler maintains a set of signatures of compiled methods.
Those signatures are necessary to emit wrappers to enable the transition
from interpreter->AOT code. Thus, they must be collected for each
assembly.
Clang will automatically compile .bc files into object code if needed, but
it's done serially. If we do the compilation ourselves, it'll be parallelized.
This makes the dontlink tests build in half the time when building for watchOS
/ Release (it drops from ~15 minutes to ~7 minutes).
The AOT compiler uses the 'outfile' as the base for a temporary .bc file. If
it's not set, the path to the assembly is used as the base instead. This does
not work if we compile the same assembly to multiple architectures (for
instance armv7k+arm64_32), because the temporary file will clash between those
AOT compilations.
This is not a problem for iOS (armv7+armv7s) because we don't compile to
bitcode (.bc files) on iOS.
* [mtouch] Don't use the native linker to create fat executables.
Don't use the native linker to create fat executables, instead link each
architecture separately, and then manually lipo everything together at the
end. This requires a few changes since we need to keep track of the linker
flags per architecture.
The problem is that bitcode files (.bc) do not correspond with a particular
architecture, so the linker can't distinguish between .bc files for armv7k and
.bc files for arm64_32. So if we pass all together to the linker, the linker
will add all .bc files to both architectures, thus duplicating everything (and
the linking fails with duplicate symbols errors).
* [mtouch] Fix building symlinked simulator executables.
* [mtouch] Fix several assumptions about each Target only producing a single executable.
Also change output to use the full path to files as nodes, instead of just the
filename, and instead use a label to set what's shown to just the filename.
This makes the graph correct when we have multiple files with the same name,
but different paths.
We need our 32-bit and 64-bit assemblies to be identical so that we can avoid
duplicating the .dll in fat apps.
One difference used to be that the .dll contained the full path to the
corresponding .pdb ([1]), but we changed cecil to only write the filename
([2]). Unfortunately this change breaks something else, so it has to be
reverted ([3]).
This implements a different solution: we provide a custom symbol writer to
Cecil, which only writes the filename of the pdb in the .dll, not the full
path.

# Conflicts:

* 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.
Sometimes we just Log a string without any format arguments. This works fine,
until the string comes from the user, and happen to contain braces, in which
case an invalid format exception is thrown.
Adding Log overloads that doesn't take format arguments (nor formats its
input) avoids this problem.

- Existing binding projects embed the native libraries within the assembly as managed resource
- This does not scale well and has performance implications
- This PR creates a new property, NoBindingEmbedding which when true processes the building and consumption of binding projects differently.
- Existing binding projects are not affected, they will continue as is
- I've written a full XM test suite and ported a subset to iOS. Since iOS only supports checked in projects, and I didn't want to make the existing situation worse by adding more, I only wrote tests that could use the existing test projects.
-When we complete some form of msbuild testing reform, we'll revisit these tests.
- Remove two files in MyiOSFrameworkBinding that are not used (we use copies elsewhere)
- Remove unnecessary sleep and fix broken touch command
- Output failing test log to console instead of test output
- VSfM does not handle thousands of lines of test failure message well
- Add ability to generate binding projects with LinkWith
* [mtouch] do not strip assemblies when interpreter is used

Visual Studio for Mac may set MONO_THREADS_SUSPEND, and this ends up confusing
the AOT compiler when compiling for watchOS.
So unset the environment variable before calling the AOT compiler.

* [runtime] Clean up public symbols. Fixes#5124.
Clean up public symbols, by:
* Symbols that don't need to be public (most of them), can be private.
* Prefix all public symbols with `xamarin_`.
* Add a test to ensure we don't introduce new public symbols.
* Use C symbols instead of mangled C++ symbols, since those are easier to
handle in the test.
This minimizes the chance of getting into a symbol clash with another native library.
Fixes https://github.com/xamarin/xamarin-macios/issues/5124.
* Some test fixes.
Share all the code to find and verify Xcode between mtouch and mmp.
Also print out the actual product version when logging which Xcode was used
(to make it easier to detect if a beta version is in use).
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).

by looking at Developer/usr instead (and also the subsequent code to locate
the bin directory was based on the location of the usr directory).
Developer/Platforms/iPhoneOS.platform/Developer/usr reappeared in Xcode 10
beta 1, but it seems useless (for one it doesn't contain a bin directory), so
in order to try to keep things sane don't look for this directory in Xcode 10
and instead go directly for Developer/usr (which is what we've been using as
the usr directory for years anyway).
Fixes this problem when building apps with Xcode 10 beta 1:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/iOS/Xamarin.iOS.Common.targets(626,3): error : Could not locate SDK bin directory [/Users/rolf/Projects/TestApp/test-app.csproj]
* [runtime] Build 32-bit mac executables using Xcode 9.4.
* [mtouch] Work around broken tvOS headers in Xcode 10 beta 1.
* [mtouch] Work around build problem with Apple's simd headers in Objective-C++ mode.
* Use version-agnostic paths to sdk directories.
* [tests][xtro] Add todo files (from unclassified) and adjust ignore files to avoid errors
* [macos][security] Re-enable SSL[Get|Set]AlpnProtocols. Fixes#4001 (#4022)
* [macos][security] Re-enable SSL[Get}Set]AlpnProtocols. Fixes#4001
This was fixed in macOS 10.13.4
https://github.com/xamarin/xamarin-macios/issues/4001
* [tests][monotouch-tests] Disable a few test cases (one crasher, other failures). Causes to be verified later
* [xharness] Fix permission dialog suppression in Xcode 10.
* [xharness] Ignore 32-bit macOS tests by default.
* [tests] Execute mmp regression tests with Xcode 9.4 since many of them are 32-bit and needs porting to 64-bit.
* [mmptest] Ignore 32-bit XM tests if we don't have a 32-bit-capable Xcode.
* [registrar] Add workaround for broken headers in Xcode 10 beta 1 (radar 40824697).
* [mtouch] Restrict another workaround for an Xcode 10 beta 1 bug to a specific Xcode version to remove it asap.
* [tests] Fix some protocol changes (public or not) find by introspection tests
* [tests][intro] Fix DefaultCtorAllowed failures
* [Intents] Obsolete several Intents classes in watchOS.
Several existing Intents classes have been marked as unavailable in watchOS in
the headers in Xcode 10 beta 1, and corresponding tests are now failing.
So obsolete the managed wrapper types, and fix tests accordingly.
* Fix xtro wrt previous Ietents/intro changes
* [tests] Minor adjustments to mtouch tests to work with Xcode 10.
* [msbuild] Update tests to cope with additional files produced by the Core ML compiler.
* [msbuild] Xcode 10 doesn't support building watchOS 1 apps, so show a clear error message explaining it.
Also update tests accordingly.
* [coreimage] Stub new filters and exclude ?removed? ones from tests
* Update GameplayKit and SpriteKit NSSecureCoding _upgrade_ and fix other non-public cases (in tests)
* [tests] Ignore some GameKit selectors that don't respond anymore (but seems to be available, at least in header files)
* [tests] Fix intro 32bits testing for filters resutls
* [msbuild] Slightly change error message to be better English.
* Share the stopwatch code between `mtouch` and `mmp`;
* Add more details on linker steps. Sadly substeps are executed on the
metadata so they can't be reported individually;
* Add a few places where timestamps where missing to get better precision
on the linking part;
On my test project we were calling `IsArchEnabled` 334,713 times which
made the enumerator called enough to show on the memory usage (13MB),
even if each instance is only 40 bytes.
Caching the result makes the method called only 5 times.
* [runtime] build interp-, icalltable- and ilgen libraries so they can be consumed in interpreter configuration
* [mtouch] add --interpreter configuration support
* [xharness] Add support for removing defines from cloned project files.
* [xharness] Run monotouch-test, mscorlib and mini tests with the interpreter too.
They're ignored for now, which means we won't run them on the bots.
* [mtouch] We're using dlsym when using the interpreter.
* [xharness] enable mini regression tests with interpreter on CI
The PR is not final and cannot be merged until the final Xcode 9.4
release from Apple is available.
Since there's no macOS specific changes (at least up to beta 2) we can
directly merge into the _normal_ milestone branch and avoid having
separate branches to maintain for XI and XM (until 15.8).
The --linker-optimize option is an early version of the current --optimize
option, and apparently I forgot to update everything when the option changed
name.
* [ClassKit] Add Xcode 9.4 Beta 1 Bindings
* ClassKit moved to v11.4 or we'd link against a private frmework in 11.3
* Turn CLSPredicateKeyPath into a static class
CLSPredicateKeyPath does not make much sense as an enum, we'll use
a static class instead so we do not have to call GetConstant() and
use the NSString directly.
Sample code using CLSPredicateKeyPath:
```csharp
var store = CLSDataStore.Shared;
var predicate = NSPredicate.FromFormat ("%K = %@", CLSPredicateKeyPath.Parent, store.MainAppContext);
var ctxs = await store.FindContextsMatchingAsync (predicate);
foreach (var ctx in ctxs) {
Console.WriteLine (ctx.Title);
}
```
* [tests] Exclude WeakTopic incorrect check, bound as smart enum
Fix https://github.com/xamarin/xamarin-macios/issues/3653 differently as
`UseShellExecute` cannot be used when redirecting output so the original
fix [1] caused an exception which affected it from both macOS and windows
(thru XMA) instead of being an issue only with the later.
It's not clear how the original [1] fix was validated successfully, it's
possible than an older version of mono did not throw (since that
limitation seems windows specific).

We haven't used libmonotouch-fixes.dylib for over a year (and it stopped
working before that), so this seems safe to remove.

expected: 'Native code sharing has been disabled for the extension 'testServiceExtension' because the managed linker settings are different between the container app (None) and the extension (All).'
which happens because:

* This results in the app and appex having different values for the remove-dynamic-registrar option
* Thus the error message.
Technically either error is correct, but I prefer the previous one (about the
linker), because it directly assigns blame (the linker setting). Figuring out
what has to change (the linker setting) when the error message complains about
an optimization is not so straight forward for users.
This fixes a startup crash in code shared app extensions due to having the
wrong value set in the runtime (the dynamic registrar was removed, but the

When code sharing is enabled, only the container app/target will have a

So make sure the static registrar finds that link context when it needs

* [mtouch/mmp] Fix tracking of whether the static registrar should run again or not.
The recent changes to support optimizing away the dynamic registrar caused the
Xamarin.MTouch.RebuildTest_WithExtensions test to regress.
The problem
-----------
* The linker now collects and stores information the static registrar needs.
* This information is not restored from disk when the linker realizes that it
can reload previously linked assemblies instead of executing again.
* The static registrar runs again (for another reason).
* The information the static registrar needs isn't available, and incorrect
output follows.
So fix 1: show an error if the static registrar runs when the linker loaded
cached results.
The exact scenario the test ran into is this:
* 1st build: everything is new and everything is built.
* 2nd build: contents of .exe changes, the linker runs again, the static
registrar runs again, but sees that the generated output didn't change, so
it doesn't write the new content to disk (this is an optimization to avoid
compiling the registrar.m file again unless needed).
* 3rd build: only the .exe timestamp changes, the linker sees nothing changes
in the contents of the .exe and loads the previously linked assemblies from
disk, the static registrar sees that the .exe's timestamp is newer than
registrar.m's timestamp and run again, but doesn't produce the right result
because it doesn't have the information it needs.
Considered solutions
--------------------
1. Only track timestamps, not file contents. This is not ideal, since it will
result in more work done: in particular for the case above, it would add a
registrar.m compilation in build #2, and linker rerun + static registrar
rerun + registrar.m compilation + final native link in build #3.
2. Always write the output of the static registrar, even if it hasn't changed.
This is not ideal either, since it will also result in more work done: for
the case above, it would add a registrar.m compilation + final native link
in build #3.
3. Always write the output of the static registrar, but track if it changed or
not, and if it didn't, just touch registrar.o instead of recompiling it.
This only means the final native link in build #3 is added (see #5 for why
this is worse than it sounds).
4. Always write the output of the static registrar, but track it it changed or
not, and if it didn't, just touch registrar.o instead of recompiling it,
and track that too, so that the final native link in build #3 isn't needed
anymore. Unfortunately this may result in incorrect behavior, because now
the msbuild tasks will detect that the executable has changed, and may run
dsymutil + strip again. The executable didn't actually change, which means
it would be the previously stripped executable, and thus we'd end up with
an empty .dSYM because we ran dsymtil on an already stripped executable.
5. Idea #4, but write the output of the final link into a temporary directory
instead of the .app, so that we could track whether we should update the
executable in the .app or not. This is not optimal either, because
executables can be *big* (I've seen multi-GB tvOS bitcode executables), and
extra copies of such files should not be taken lightly.
6. Idea #4, but tell the MSBuild tasks that dsymutil/strip doesn't need to be
rerun even if the timestamp of the executable changed. This might actually
work, but now the solution's become quite complex.
Implemented solution
--------------------
Use stamp files to detect whether a file is up-to-date or not.
In particular:
* When we don't write to a file because the new contents are identical to the
old contents, we now touch a .stamp file. This stamp file means "the
accompanying file was determined to be up-to-date when the stamp was
touched."
* When checking whether a file is up-to-date, also check for the presence of a
.stamp file, and if it exists, use the highest timestamp between the stamp
file and the actual file.
Now the test scenario becomes:
* 1st build: everything is new and everything is built.
* 2nd build: contents of .exe changes, the linker runs again, the static
registrar runs again, but sees that the generated output didn't change, so
it doesn't write the new content to disk, but it creates a registrar.m.stamp
file to indicate the point in time when registrar.m was considered up-to-
date.
* 3rd build: only the .exe timestamp changes, the linker sees nothing changes
in the contents of the .exe and loads the previously linked assemblies from
disk, the static registrar sees that the .exe's timestamp is *older* than
registrar.m.stamp's timestamp and doesn't run again.
We only use the stamp file for source code (registrar.[m|h], main.[m|h],
pinvokes.[m|h]), since using it every time has too much potential for running
into other problems (for instance we should never create .stamp files inside
the .app).
