…re. (xamarin#3391) * [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.

The MSBuild tasks will codesign an executable if the executable's timestamp is later than `_CodeSignature/CodeResources`'s timestamp (or if `_CodeSignature/CodeResources` doesn't exist). Unfortunately, the codesign executable modifies both of those files, and the executable last. This means that even just after running codesign, the executable's timestamp might be later than `_CodeSignature/CodeResources`'s timestamp (due to HFS+'s one-second timestamp resolution, this might happen all within the same second, which means that this is a random issue: the problem only occurs if the executable was modified at least a second later than `_CodeSignature/CodeResources`.) So make sure to touch `_CodeSignature/CodeResources` after running codesign, so that the next time a build occurs (with no modifications), we don't resign needlessly. Fixes this (random) test failure when running the MSBuild tests: 1) Test Failure : Xamarin.iOS.Tasks.TargetTests.RebuildExecutable_NoModifications #1: ../MySingleView/bin/iPhoneSimulator/Debug/MySingleView.app/MySingleView Expected: 2017-11-30 10:04:20.000 But was: 2017-11-30 10:04:22.000 Fixes xamarin/maccore#592.

xamarin#6011) * [msbuild] Add reference to `System.Drawing.Common.dll` to XI projects. Fixes mono/mono#13483 : ``` @akoeplinger: Since we moved types from Mono.Android.dll and Xamarin.iOS/WatchOS/TVOS.dll to System.Drawing.Common.dll user projects would fail to compile. We need to add some msbuild logic to add a reference to the assembly automatically. ``` * [msbuild] Implement the same fix for XM projects as well. * [msbuild] Update Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_* tests. We're including a new assembly, which means the Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_* must be updated accordingly. Also modify these tests so that test assert that fails lists the actual assembly that's missing, i.e. instead of this: 1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable #1 Expected: 6 But was: 7 we now print: 1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable References Expected: equivalent to < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Xml.dll", "Xamarin.iOS.dll" > But was: < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Drawing.Common.dll", "System.Xml.dll", "Xamarin.iOS.dll" > * [tests] Adjust Xamarin.MMP.Tests.AssemblyReferencesTests.ShouldNotAllowReference_ToSystemDrawing. The test was verifying that referencing System.Drawing.dll and trying to use System.Drawing.RectangleF would fail to compile (because System.Drawing.dll shouldn't be resolved in this case). The addition of System.Drawing.Common.dll breaks this assumption, because now we ship System.Drawing.RectangleF, so the code that was supposed to fail to compile works just fine instead.

…projects. (xamarin#6035) * [msbuild] Add reference to `System.Drawing.Common.dll` to XI projects. Fixes mono/mono#13483 : ``` @akoeplinger: Since we moved types from Mono.Android.dll and Xamarin.iOS/WatchOS/TVOS.dll to System.Drawing.Common.dll user projects would fail to compile. We need to add some msbuild logic to add a reference to the assembly automatically. ``` * [msbuild] Implement the same fix for XM projects as well. * [msbuild] Update Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_* tests. We're including a new assembly, which means the Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_* must be updated accordingly. Also modify these tests so that test assert that fails lists the actual assembly that's missing, i.e. instead of this: 1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable #1 Expected: 6 But was: 7 we now print: 1) Test Failure : Xamarin.iOS.Tasks.TargetTests.GetReferencedAssemblies_Executable References Expected: equivalent to < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Xml.dll", "Xamarin.iOS.dll" > But was: < "mscorlib.dll", "MyLibrary.dll", "System.Core.dll", "System.dll", "System.Drawing.Common.dll", "System.Xml.dll", "Xamarin.iOS.dll" > * [tests] Adjust Xamarin.MMP.Tests.AssemblyReferencesTests.ShouldNotAllowReference_ToSystemDrawing. The test was verifying that referencing System.Drawing.dll and trying to use System.Drawing.RectangleF would fail to compile (because System.Drawing.dll shouldn't be resolved in this case). The addition of System.Drawing.Common.dll breaks this assumption, because now we ship System.Drawing.RectangleF, so the code that was supposed to fail to compile works just fine instead. So modify the test to verify that there's no System.Drawing.dll in the final bundle. * Remove workarounds for mono/mono#13483. * [msbuild] Create a way out if automatically referencing System.Drawing.Common.dll causes problems. * [msbuild] Adjust variable name and boolean logic according to review.

…s in .NET (xamarin#9464) A System.Drawing.Point test fails because it tests GetHashCode, which returns a different value in .NET.

Not sure why it was added to `DisposableObject` but it seems the compiler is not happy to use the extension method for the `NativeObject` subclass even if it implement `INativeObject` (that might be the reason why?) So remove it from `NativeObjectExtensions` for .net - as I guess it's too late to remove from the recent `DisposableObject` in legacy. The platform assemblies only use it for `NativeObject` subclass so it's not an big issue... as I assume there's not many `INativeObject` user code that does not use (or should be using) `NativeObject`. Fix #1: avoid using `IntPtr` when `NativeHandle` is defined since the compiler will add (not really needed) implicit conversions everywhere. Fix #2: ensure the spirit/contract of `GetCheckedHandle` always work. IOW the goal of `GetCheckedHandle` is to ensure you never get a `nil` handle, since some native API will crash if they given `nil` However it's still currently possible, with multithreaded code, to get a `Zero` value from `GetCheckedHandle`. From a quick look at the C# code it seems fine. It's easier to see the problem looking at the IL. ```il .method public hidebysig instance valuetype ObjCRuntime.NativeHandle GetCheckedHandle () cil managed { // Method begins at RVA 0x6c8c // Header size: 1 // Code size: 31 (0x1f) .maxstack 8 IL_0000: ldarg.0 IL_0001: ldfld valuetype ObjCRuntime.NativeHandle ObjCRuntime.DisposableObject::handle IL_0006: ldsfld valuetype ObjCRuntime.NativeHandle ObjCRuntime.NativeHandle::Zero IL_000b: call bool ObjCRuntime.NativeHandle::op_Equality(valuetype ObjCRuntime.NativeHandle, valuetype ObjCRuntime.NativeHandle) IL_0010: brfalse.s IL_0018 IL_0012: ldarg.0 IL_0013: call void ObjCRuntime.ThrowHelper::ThrowObjectDisposedException(object) IL_0018: ldarg.0 IL_0019: ldfld valuetype ObjCRuntime.NativeHandle ObjCRuntime.DisposableObject::handle IL_001e: ret } // end of method DisposableObject::GetCheckedHandle ``` `IL_0001` loads the field and then `IL_006` compares it to `Zero`. If it's not `Zero` then `IL_0019` loads the field **again** before returning it `IL_0001e` to the caller. So if another thread sets the `handle` of this instance to `Zero` between the two `ldfld` instructions then the caller will get `Zero` and this can crash the application. Of course what will happen if you use the _old_ handle is _somewhat_ undefined and depends if the native object still exists. There's a **very** good chance it does it the managed object i running (so it has not been collected).
