* [build] Use arcade dependency management tooling
* Apply feedback
* Apply second round of feedback
* Always make dotnet.config before trying to read it
* Debugging
* Update dependencies, trim tabs and spaces
* [dotnet] Remove the existing workload shipped with .NET and install our locally built ones.
The new version of .NET ships with our workloads, but those aren't
the workloads we want to use, so replace them with our own.
* Update .gitignores.
* Bump to 6.0.100-preview.3.21181.5
That required renaming simulator runtime packs...
* More rename for simulator packages
* moar (hopefully all)
* Bump to 6.0.100-preview.3.21201.11
This fix the issue with `Wait` that failed several tests in monotouch-tests
However it does not include the fix for AppConext.GetData on device (AOT)

* [runtime] Download the CoreCLR embedding header file
* [runtime] Create VM-specific code and header files and include them in the build
* [runtime] Move MonoVM-specific initialization to MonoVM-specific code.
* Add support for Xamarin.Mac arm64
* Add compile product definition task
Xamarin.Mac can be provided with a ProductDefinition file for the generated pkg. Normally, providing a product definition was optional. However, with Apple Silicon, we have an extra issue : `productbuild` needs to know what architectures your package target. If not provided with them, it will guess to the best of its abilities. However, on Catalina and lower, the guess is x86_64, even if you have an arm64 slice. To fix this, we add a new task to compile the product definition and use this file to create the pkg. If you provide your own Product Definition, we can check and warn if the architectures don't match what we expect. If the file doesn't exist or there is no architecture, we set it ourselves based on our target architectures.
* Don't reference dynamic objC_send on arm64
When building in debug, we currently try to link dynamic objC_send symbols when targeting a 64-bit architecture. However, this is actually only defined on Intel architectures, not on arm64, so we end up failing because we're referring symbols that don't exist. Rework the `GetRequiredSymbols` to take an abi, and tag those symbols to only be valid on i386/x86_64, so they don't get referred at all when building on arm64, but still get referred in x86_64.
* Fix improper delete/move with already existing directories
* Fix stret requirement for Xamarin.Mac in arm64.
The generator supposes that we're running in x64 mode, refactor to take into account the possibility of running in arm64.
* Implement OS version generation in Product.plist, based on MinimumSystemVersion of the app
* Re-generalize some mmp registrar rules
`Microsoft.macOS.registrar` was missed by the current rule set
* Fix mmp tests
* Set E7072 as not translated
Tests were failing otherwise
* Rename Xamarin.Mac lib/x86_64 folder to 64bits (currently all targeted archs are the same)
* Fix style issues
* Fix `ToLower` usage for invariant usage
* Fix xtro-sharpie test
* [runtime] Link the coreclr version of libxamarin with CoreCLR instead of Mono.
The diff might look a bit weird, because there's no changes specific to CoreCLR -
the difference is that we're in fact removing a special-case to link with Mono: we
used the DOTNET_$(rid)_LIBDIR variable to specify the directory where to find libcoreclr,
we now use DOTNET_CORECLR_$(rid)_LIBDIR when building for CoreCLR, but that's handled
by the default case, so no need to add any special casing. We still override DOTNET_osx-<arch>_LIBDIR
for MonoVM (no change needed for that).
* [runtime] Generate stubs for the mono embedding API when building for CoreCLR.
This makes libxamarin link successfully when building for CoreCLR.
Make variables can have dashes, which means we don't have to convert dashes in
rids to underscores to be able to compose variable names.
This speeds up make because now we don't have to execute hundreds of
subprocesses when parsing the makefile.
Before:
$ make -j16 > /dev/null && /usr/bin/time make && /usr/bin/time make && /usr/bin/time make
2.11 real 0.57 user 1.26 sys
2.15 real 0.57 user 1.28 sys
2.17 real 0.58 user 1.30 sys
After:
$ make -j16 > /dev/null && /usr/bin/time make && /usr/bin/time make && /usr/bin/time make
0.52 real 0.18 user 0.25 sys
0.52 real 0.18 user 0.25 sys
0.52 real 0.18 user 0.26 sys
So now it's ~4x faster (1.6s) for make to figure out there's nothing to do.
* Add configure option to disable building for legacy Xamarin.
This can greatly speed up the debug-edit-build cycle when doing .NET
development, since it cuts down the build time in half more or less.
* Bump maccore.
New commits in xamarin/maccore:
* xamarin/maccore@548fa45432 [mlaunch] Disable building mlaunch when not including the legacy Xamarin build. (#2403)
Diff: 0562e08b12..548fa45432
This also means linking with the runtime packs from .NET instead of the mono archive
(thus we have one less reliance on the mono archive).
We're also using the Xamarin.iOS code for our macOS launch sequence now, since
(at least at first) we're only going to support self-contained .NET macOS apps
(so no need to support a system-installed runtime, which simplifies things a
bit).
Split the make template 'PlatformTemplate' in two templates, now there's a 'FrameworkTemplate'
that's in charge of building Xamarin[-debug].framework, and the existing 'PlatformTemplate'
will be in charge of the rest of the native libraries.
* [watchOS] Add x86_64 simulator support
* Build runtime/registrar x86_64 slices
* Produce a 64 bit version of Xamarin.WatchOS.dll
* Allow building x86_64 for watch simulators in mtouch
* Let xharness know about x86_64
* [tests] Add x86_64 arch to test-libraries
* Make dotnet package aware of x64
* [ObjCRuntime] Fix computing if we're calling a stret function or not in a 64-bit watchOS simulator.
* [xharness] Re-enable some watchOS tests.

* [dotnet] Fix install name for libxamarin[-debug].dylib on macOS
* When using DYNAMIC_MONO_RUNTIME pass down the bundle directory in MONO_PATH to the relaunched process. Also fix support for custom bundle names in the surrounding code.
* Fix pattern matching
* [dotnet] Ship libxamarin.dylib and friends.
Add libxamarin[-debug].[a|dylib] to the NuGets.
* [dotnet] Create a DOTNET_PLATFORMS variable in Make.config.
Create a DOTNET_PLATFORMS variable in Make.config and use it everywhere
instead of the PLATFORMS variable we were defining in multiple Makefiles.
Also move the creation of the DOTNET_<platform>_RUNTIME_IDENTIFIERS variables
from dotnet/Makefile to Make.config, it'll soon be needed elsewhere as well.
* [runtime] Conditionally include bits.
* Make the contents of the DOTNET_[PLATFORMS|RUNTIME_IDENTIFIERS] variables depend on the INCLUDE_[IOS|TVOS|WATCH] variables.
That's in /Library/Frameworks/Xamarin.Mac.framework/Versions/Current/SDKs/Xamarin.macOS.sdk/[lib|include]
This allows for a bit more code share between mtouch and mmp.
* Rearrange files in Xamarin.Mac a bit to ease code sharing between mmp and
mtouch, by putting mono's static and dynamic libraries in
/Library/Frameworks/Xamarin.Mac.framework/Versions/Current/Sdks/Xamarin.macOS.sdk
to match how Xamarin.iOS does it.
* Don't use 'usr' as an intermediate directory. This removes another special
case.
* Share many of the functions and properties that return specific directories,
and document (as comments) what each function/property is supposed to
return.
This is restricted to debug builds.
Also tell make to not delete delegates.h and delegates.inc. That makes it much
easier to inspect them.
Example before function:
void
xamarin_throw_ns_exception (NSException * exc)
{
delegates.throw_ns_exception (exc);
}
The after version:
void
xamarin_throw_ns_exception (NSException * exc)
{
#if DEBUG
if (delegates.throw_ns_exception == NULL) {
NSLog (@PRODUCT ": The managed function throw_ns_exception could not be loaded.");
xamarin_assertion_message ("The managed function throw_ns_exception could not be loaded.");
}
#endif
delegates.throw_ns_exception (exc);
}
We inject an x86-64 slice into binaries that don't contain one, because
Apple's notarization process fails without such a slice.
But make the slice optional and opt-in, because it seems Apple has started
to fail on binaries with such a slice now...
Make csc to bee more strict when compiling the projects and mix some
small errors we had in the bindings.

Fixes: https://github.com/xamarin/xamarin-macios/issues/5398
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.
* Drop the Xcode 9.4 dependency.
Also bump mono to get the removal of the mac32 binaries.

* [tests] Add a fat macOS dylib for testing purposes.
Add a binary version of a fat macOS dylib (because we can't create one when we
need it since we can't create 32-bit slice anymore).
It was created like this (in tests/test-libraries):
$ cat test.m
int theUltimateAnswer ()
{
return 42;
}
$ /Applications/Xcode94.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang test.m -olibtest.i386.dylib -shared -isysroot /Applications/Xcode94.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -framework Foundation -framework CoreLocation -lz -arch i386
$ lipo -create libtest.i386.dylib .libs/macos/libtest.dylib -output libtest-fat.dylib
* [tests] Adjust XM tests to XM not having fat dylibs anymore.
* [tests] Adjust product tests to some libraries not being fat anymore.
* One more test fix.
* 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.
It's now required to cast objc_msgSend[Super] to a function of the correct
signature, so let's do that.
Also remove the define that allowed us to use the previous behavior.
* 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
See https://github.com/mono/mono/issues/14843
* 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.

* [mmp] Fix make clean target
It needs an -r to remove directories:
```
rm: bin: is a directory
rm: obj: is a directory
```
* Add new xamarin_timezone_get_local_name() to a few more places
This includes:
* 32-bit version of Xamarin.Mac.dll and OpenTK.dll
* XamMac.dll and XamMac.CFNetwork.dll
* 32-bit versions of the runtime libraries (libxammac.a and friends).
* 32-bit version of the partial static library for Xamarin.Mac.
* Classic support in the generator.
We still ship a few Classic files so that Visual Studio for Mac continue to detect that Xamarin.Mac is installed (otherwise VSfM won't open Classic projects, which makes it impossible to use the migration wizard).
This makes our build slightly faster.
Partial fix for #6300.
* [registrar] Make a copy of the static registrar for Xamarin.Mac/Classic.
Make a copy of the static registrar for Xamarin.Mac/Classic, one which is
compatible with the binary artifacts we ship for Xamarin.Mac/Classic
(libxammac, XamMac.dll).
This way the static registrar can evolve in the future, without breaking
Xamarin.Mac/Classic.
* [runtime] Make a copy of the runtime headers too.
* Update comment.
* [mmp] Delay creating a Target instance until we know if we're a Classic or Unified app.
Otherwise the wrong static registrar might be created.
* MIN_OSX_SDK_VERSION: the minimum macOS version we support for running macOS apps.
* MIN_OSX_VERSION_FOR_MAC: the minimum macOS version we support for running XM/XI themselves.
Change our build to make sure the above is respected, and in particular:
* The mac32 and mac64 builds must use MIN_OSX_SDK_VERSION.
* The runtime/ build must use MIN_OSX_SDK_VERSION.
* The tools64 build should use MIN_OSX_VERSION_FOR_MAC.
Also document a bit better the various version variables.
