5726 # Mono.Native Support
5727 # -------------------
5728 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5729 # It is built as a stand-alone shared library and not bundled with the runtime because we
5730 # may need to build two different versions of it.
5731 #
5732 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5733 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5734 #
5735 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5736 # implementation accordingly. We build a single `libmono_native` shared library.
5737 #
5738 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
5739 #
5740 # During the mobile build, we are called with `CC` containing an explicit minium version flag,
5741 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
5742 # depending on platform.
5743 #
5744 # We build two versions of the shared library:
5745 # - `libmono_native_compat` is built with whichever minimum version is passed to us via `CC`.
5746 # - `libmono_native_unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
5747 #
5748 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
5749 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
5750 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/System/Mono/MonoNativePlatform.cs).
5751 #
5752 # This can be called by automated tests both to ensure that the library has been correctly installed and also
5753 # to verify that it's the correct version of it.
