* Continue using our own error handling logic, and print our problems to stderr.
* Also use the linker's messaging facilities to report a more generic error,
in case stderr doesn't show up for some reason.
Sometimes we wrap exceptions to add more information to what's happening, but
that may end up worse if we don't print out the wrapped exceptions.
At the same time we don't want to flood the user with information if they
didn't ask for it, so only show nested exceptions if they're something we
raised ourselves.
This fixes a startup crash in the simulator with Xcode 12:
Library not loaded: /usr/lib/libnfshared.dylib
Referenced from: /Applications/Xcode_12.0.0-GMb.app/Contents/Developer/Platforms/iPhoneOS.platform/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS.simruntime/Contents/Resources/RuntimeRoot/System/Library/Frameworks/CoreNFC.framework/CoreNFC
Reason: no suitable image found. Did find:
/usr/lib/libnfshared.dylib: mach-o, but not built for platform iOS-sim
Ref: https://stackoverflow.com/q/63915728/183422
Make the bgen tests pass in the path to the attribute library, platform
assembly and all the .NET reference assemblies to bgen. This way we execute
these tests using the .NET version of everything.
* Use the existing information we have in the Frameworks class to determine
whether a particular framework works in the simulator or not.
* Show a warning (MX5223) when we run into such a framework, but only if
the linker is enabled (otherwise we'll often get warnings for API the developer
doesn't use).
* [xcode12] Initial bump for Xcode 12 GM
* [tests][intro] We cannot load CoreNFC framework on iOS simulator anymore
* [tests][xtro] New Metal API are not abstract (before XAMCORE_4_0)
* [tests][intro] Fix crash when CSLocalizedString 'description' selector is called
* [tests][xtro] Add support for excluding platforms
Based on `Make.config` variables `INCLUDE_[IOS|TVOS|WATCH|MAC]`
This required moving some entries (common -> macOS) to keep the

Some appextension mtouch code had to be moved to shared code. This code is currently
only used for iOS/tvOS/watchOS, but it will eventually be applicable to macOS as
well.
This makes it possible to re-use the registrar code in dotnet-linker.
Fixes these linkall tests:
Linker.Shared.OptimizeGeneratedCodeTest
[FAIL] IsARM64CallingConvention : optimized: no ldsfld instruction
Expected: 0
But was: 1
at Linker.Shared.BaseOptimizeGeneratedCodeTest.IsARM64CallingConvention() in /Users/rolf/work/maccore/main/xamarin-macios/tests/linker/BaseOptimizeGeneratedCodeTest.cs:line 527
[FAIL] SetupBlockPerfTest : At least 6x speedup
Expected: greater than 6
But was: 1.0876440665344851d
at Linker.Shared.BaseOptimizeGeneratedCodeTest.SetupBlockPerfTest() in /Users/rolf/work/maccore/main/xamarin-macios/tests/linker/BaseOptimizeGeneratedCodeTest.cs:line 120
And linkall is now green for .NET/Debug.
Refactor the Optimizations class to have no conditionally compiled code, which makes
it re-usable from our dotnet-linker code.
Also return any errors or warnings instead of showing/throwing them, which makes
the caller able to show them using whatever means is easiest for the caller.
One test needed an update to the list of valid optimizations, because we now have
a per-platform map of valid optimizations, instead of just a iOS/tvOS/watchOS vs
macOS split ('remove-unsupported-il-for-bitcode' is only valid for watchOS, and now
we say so, while we previously said it was a valid optimization for iOS and tvOS
as well, even though we'd warn about it and do nothing if you tried to set it).
The Assembly.IsFrameworkAssembly property is used in two places:
* In Driver.IsBoundAssembly to return early when determining if an assembly has any NSObject subclasses: c1c5b9aac6/tools/mtouch/mtouch.cs (L1155-L1168)
* In Assembly.ExtractNativeLinkInfo to return early when looking for assemblies with LinkWith attributes: c1c5b9aac6/tools/common/Assembly.cs (L150-L154)
In both cases this definition of framework assembly works today and seems likely to work in the future as well.
I also went through and looked at all the usages of Profile.IsSdkAssembly, and it's used to:
* Decide which assemblies are selected for "link sdk"
* Decide which assemblies are considered an 'sdk' assembly for creating a user framework of all the sdk assemblies
* Bail out early when deciding whether:
* An assembly references the product assembly (Xamarin.iOS.dll, etc.)
* An assembly can contain references to UIWebView
* An assembly can contain user resources
* An assembly is a binding project / has third-party native resources
* An assembly needs the dynamic registrar
* An assembly has FieldAttributes whose native fields must be preserved by the native linker
In all cases our .NET definition of 'SDK' seems to work both for now and in the future.
There are also a few usages which does not apply to .NET, so I've ignored them:
* When looking for a few BCL APIs that must be preserved (MobileApplyPreserveAttribute.cs): this is to be done in the upstream .NET linker now, so it doesn't apply to our own code
* When linking away parameter names (MonoTouchMarkStep.cs): this is to be done in the upstream .NET linker now, so it doesn't apply to our own code
* [mmp] Rename LinkMode.All to LinkMode.Full.
So that we can continue to use Enum.Parse<LinkMode> to parse 'Full' as the link mode.
* [dotnet] Implement support for our different link modes.
Tell the managed linker what to do with each input assembly depending the selected
link mode (link all, link sdk, don't link).
Refactor Application creation to happen earlier, and to split out the cache
creation. This way we can create the Application instance before processing
the configuration, and as we process any configuration we can set properties
on the Application instance.
If we can't find the mscorlib assembly in the list of loaded assemblies, try to load
it explicitly. If we still can't find it the mscorlib assembly, look for System.Void
in any assembly. This shouldn't be a performance bottleneck, because we cache the
System.Void type, which means the lookup is only done once.
This makes System.Void lookup work when building with .NET as well, since there's
no mscorlib.dll there.
This is required when running mtouch and mmp to generate the partial static registrar
code for .NET.
* Port the interdependent-binding-projects test to .NET (it's the simplest
test project we have with binding projects).
* Add a lot of the shared source code for mtouch/mmp to dotnet-linker, and
make it compile. Most issues were fixed by adding a few stubbed out classes,
since there are large chunks of the mtouch/mmp code we're not using yet, so
stubbing out while things are being implemented works fine.
* Add a step in dotnet-linker for loading the linker output (the linked
assemblies) into our bundler code.
* Add another step in dotnet-linker to extract native resources from binding
libraries.
* Augment the build process to take into account the native resources we found
in any binding libraries.
This fixes an issue where mtouch would complain about a missing --target-framework argument when it's not actually needed:
/Library/Frameworks/Xamarin.iOS.framework/Versions/Current/bin/mtouch --launchsim bin/iPhoneSimulator/Release/MyApp.app [...]
error MT0086: A target framework (--target-framework) must be specified.
what makes this worse is that passing --target-framework to mtouch makes
mlaunch fail, because mlaunch doesn't accept a --target-framework argument.
Turns out we don't actually _need_ to know, in every case we use this knowledge it's
a performance improvement to not process the framework assemblies, so skip this for
now, since there's no harm done (except to the planet) to do some extra processing
by processing all assemblies in these cases.
