1034 #--with-crash_privacy=yes --with-structured_crashes=no means we don't wanna dump in non-merp-enabled builds, and we want to not send symbol strings. This is going to be the default pair of settings for VS4Mac.

5988 # Mono.Native Support
5989 # -------------------
5990 # Mono.Native is the new name for both System.Native and System.Security.Cryptography.Apple.
5991 # It is built as a stand-alone shared library and not bundled with the runtime because we
5992 # may need to build two different versions of it.
5993 #
5994 # Starting with macOS 10.12+ and iOS 10+, Apple introduced a new Unified API for some of the
5995 # crypto primitives that we're using as part of System.Security.Cryptography.Apple.
5996 #
5997 # On Desktop, we can check at runtime whether the OS version is recent enough and switch
5998 # implementation accordingly. We build a single `libmono-native` shared library.
5999 #
6000 # However, on Mobile we cannot have any undefined symbols as this would break Bitcode.
6001 #
6002 # During the mobile build, we are called with `CFLAGS` containing an explicit minium version flag,
6003 # which is eiter `-mmacosx-version-min=`, `-mios-simulator-version-min=` or `-miphoneos-version-min=`
6004 # depending on platform.
6005 #
6006 # We build two versions of the shared library:
6007 # - `libmono-native-compat` is built with whichever minimum version is passed to us via `CFLAGS`.
6008 # - `libmono-native-unifed` is built with the minimum version set to macOS 10.12+ / iOS 10+.
6009 #
6010 # For testing purpuses, there is a function called `mono_native_get_platform_type ()`
6011 # (see mono/native/mono-native-platform.c), which returns a `MonoNativePlatformType` enum value.
6012 # There is also `Mono.MonoNativePlatform.GetPlatformType ()` (see mcs/class/corlib/Test/Mono/MonoNativePlatform.cs).
6013 #
6014 # This can be called by automated tests both to ensure that the library has been correctly installed and also
6015 # to verify that it's the correct version of it.

6278 #
6279 # We have to lie to autotools, sometimes.
6280 #
6281 # If we're building with llvm compiled into Mono, set MONO_CXXLD to CXX,
6282 # otherwise to CC. We want C linking even if we're compiling with C++ enabled
6283 # because we do not want to link inthe C++ runtime library (-lstdc++ or -lc++),
6284 # except if we're linking with LLVM which relies on it.
6285 #
6286 # Explanation of the hack:
6287 #
6288 # According to
6289 # https://www.gnu.org/software/automake/manual/html_node/How-the-Linker-is-Chosen.html,
6290 # automake chooses the linker that it used to compile a target based on the
6291 # _SOURCES for that target. If the target is comprised of only C code, it
6292 # chooses the C linker (on Linux and OSX this is just gcc or clang called with
6293 # linker arguments and a -o). If the target _SOURCES include at least one C++ file,
6294 # then automake chooses the C++ linker (usually g++ or clang++ called with linker arguments and -o).
6295 #
6296 # The problem for Mono is that we don't want the C++ runtime library (libstdc++
6297 # or libc++) linked in - even when Mono is written in C++, we take care not to
6298 # require the runtime library. As a result, we don't want g++ or clang++ to do
6299 # the linking. On the other hand if LLVM is enabled, then we _must_ use the
6300 # C++ linker - LLVM doesn't have the same restrictions.
6301 #
6302 # So the trick is we set MONO_CXXLD here to $CXX or $CC and in
6303 # mono/mini/Makefile.am.in we have CCLD=$MONO_CXXLD and CXXLD=$MONO_CXXLD which bypasses
6304 # automake's autodetection and lets us use the linker that we want.
