* [mtouch] Put 'mono_profiler_startup_log' in the symbol list. Fixes#58778. (#2501)
We need the 'mono_profiler_startup_log' symbol when profiling is enabled, so
make sure to add the symbol to the correct list of symbols we need.
Previously we were passing `-u _mono_profiler_startup_log` to clang directly,
which is fine, but not complete, since it does not write the symbol to the
symbollist file (--symbollist=file), which means it wouldn't be preserved when
the MSBuild tasks strip the executable.

* [mtouch/mmp] Set CultureInfo.CurrentCulture according to LANG.
This makes it easier to run mtouch/mmp under different locales when testing.

Fix collecting required internal symbols which aren't in the objc_msgSend
family by not bailing out early for a function which isn't in the objc_msgSend
family.
Also add a test.
* [mtouch] Don't allow building for 32-bit when deployment target is >= 11. Fixes#57966.
Also bump maccore to get an mlaunch error for launching a 32-bit app in a 64-bit-only simulator.
https://bugzilla.xamarin.com/show_bug.cgi?id=57966
* [tests][msbuild] Make sure all Info.plists have deployment targets.
Otherwise we get different behavior (32-bit allowed or not) depending on which
Xcode is used to build.
* [mtouch] Default to 64-bit arch if not specified and targeting iOS 11+.
* [tests] Tweak tests to either specify a deployment target < 11 or not build a 32-bit arch.
When we process P/Invokes to add support for exception marshaling, we may
change P/Invokes to be __Internal. This means that we need to move the check
for __Internal P/Invokes to after processing P/Invokes for exception
marshaling.

Previously the assumption was that if an assembly not using dlsym references a
native symbol, it's not a required symbol. This is true as far as the native
linker goes: the native linker will see that the native symbol is referenced
by the AOT-compiled code, and it won't be removed.
However, we use also this exact logic to create the list of functions we ask
the native strip command to preserve, and in this case we need to include all
symbols needed in all assemblies that looks up native functions using dlsym.

HFS normalizes filenames to Form D when files are stored. This means that an
assembly whose assembly name is stored in Form C might be stored in a file
whose filename is Form D (which you'll get if you use the Form C filename).
However, this is a problem when we've already loaded an assembly and if we
doesn't take normalization into account: we check the cache based on the
filename, but store in the cache based on the assembly name. If those two uses
different normalization schemes, bad things (bug #57266) happen.
So in these scenarios normalize strings before comparing them.

* [mtouch] Improve how we make sure native symbols aren't stripped away. Fixes#51710 and #54417.
* Refactor required symbol collection to store more information about each
symbol (field, function, Objective-C class), and in general make the code
more straight forward.
* Implement support for generating source code that references these symbols,
and do this whenever we can't ask the native linker to keep these symbols
(when using bitcode). Additionally make it possible to do this manually, so
that the source code can be generated for non-bitcode platforms too (which
is useful if the number of symbols is enormous, in which case we might
surpass the maximum command-line length).
* Also make it possible to completely ignore native symbols, or ignore them on
a per-symbol basis. This provides a fallback for users if we get something
right and we try to preserve something that shouldn't be preserved (for
instance if it doesn't exist), and the user ends up with unfixable linker
errors.
* Don't collect Objective-C classes unless they're in an assembly with
LinkWith attributes. We don't need to preserve Objective-C classes in any
other circumstances.
* Implement everything for both Xamarin.iOS and Xamarin.Mac, and share the
code between them.
* Remove previous workaround for bug #51710, since it's no longer needed.
* Add tests.

* [mtouch] Make sure to only keep symbols from the current app when code sharing.
This fixes a build problem with the interdependent-binding-projects test when
testing in Today Extension mode.
In 11390f119c we stopped setting the force flag
when the cache was invalid, because we'd delete the cache anyway, and it was
determined that deleting the cache was enough.
Unfortunately it's not, because some output is not in the cache, and might not
get correctly updated.
Scenario:
* User builds app.
* User changes some build option (for instance switching off incremental
builds).
* User does an insignificant change in a source file for the executable
process.
* User builds app again (without cleaning). This will rebuild the exe, but
since the change was insignificant, all the IL, except the MVID, would
remain identical.
* mtouch would see that the command-line options changed, and invalidate the
cache. This would delete the cache, and everything would be rebuilt,
including AOT-compiling the assemblies again.
* When the time came for mtouch to copy assemblies to the app directory,
mtouch would realize that the existing .exe in the app (which was not
deleted because it's not in the cache, but the actual output directory) was
only insignificantly different (only the MVID was different, which our cache
logic knows to ignore when comparing assemblies), so it wouldn't copy the
.exe to the .app.
* At runtime we'd assert, because the MVID in the aot-compiled code was
different from the MVID in the assembly:
error: Failed to load AOT module '(null)' while running in aot-only mode: doesn't match assembly.
* The exact assert varies depending on which build option changed. Other
variations:
Failed to load AOT module '(null)' while running in aot-only mode: compiled against GC (4, while the current runtime uses GC sgen)
* Assertion at /Users/builder/data/lanes/4691/0719ced1/source/xamarin-macios/external/mono/mono/metadata/metadata.c:1118, condition `idx < t->rows' not met
Because of this I'm reverting 11390f119c, and
once again setting the force flag when the cache is invalid. It might be
overkill, but it's the safest option (cache invalidation is after all the only
hard problem in computer science), and bugs are very annoying and
timeconsuming to track down.

```
Some of the above types from System.dll implemented ObjCRuntime.INativeObject
(from System.dll), which our linker detected as implementing
ObjCRuntime.INativeObject (from Xamarin.iOS.dll), so these types were treated
as custom NSObject subclasses, and the MarkNSObjects linker step would mark
them (which would in turn cause all the other types in the list to be marked).
With that change, these types now implement ObjCRuntimeInternal.INativeObject,
and the linker does not treat them as custom NSObject subclasses anymore.
I think the new behavior is correct: these types do not actually inherit from
the real NSObject/INativeObject, so the linker should not treat them as such.
This may run into different bugs because the linker might now remove more
stuff than before, but that would be a different issue.
This means that the fix is to modify these tests accordingly.

* Bump mono to latest.
* Fix merge conflict that was missed
* [mtouch] Renumber new error which clashes with an existing error number in master.
* [mtouch] Allow code sharing assemblies from multiple locations if they're identical. Fixes#56498.
We disallow code sharing when the same assembly (based on name) is referenced
from multiple paths, but poke a hole in this logic by allowing the same
assembly from multiple paths when those assemblies are 100% identical, since
that should be 100% safe.
https://bugzilla.xamarin.com/show_bug.cgi?id=56498
* [tests] Comment out assert that asserts due to another bug.
If both an extension and the container app (or multiple extensions) reference
the same binding assembly for a framework, then we'd error out with an
internal error when trying to copy the framework from both locations to the
container app.
So instead detect when we're trying to copy multiple identical (by comparing
the on-disk contents) frameworks, and only copy one of them.
We'll still show an error if the frameworks are different, but now a nice
MT1035 error with a proper error description instead of an internal error.
https://bugzilla.xamarin.com/show_bug.cgi?id=56635
* [mmp/mtouch/ObjCRuntime] Calculate the path to the runtime-options.plist using NSBundle's ResourcePath.
The anatomy of apps and frameworks differ between iOS and macOS:
* iOS: we put runtime-options.plist in the root directory of the app.
* macOS:
* for apps we put runtime-options in foo.app/Contents/Resources
* for frameworks we put runtime-options in foo.framework/Versions/Current/A/Resources
Luckily NSBundle's ResourcePath property returns exactly this path, so change
our logic to use this property.
Also calculate the NSBundle using an exported type we know we have (using the
main bundle won't work when we're a framework).
* [tests] Add mmp/mtouch tests to verify the default HttpClientHandler according to build arguments.
* [ObjCRuntime] Use a custom class for finding the bundle.
Use a self-defined custom class to find the bundle where our resources are.
Using the internal NSObject.NSObject_Disposer class doesn't work when this
file (RuntimeOptions.cs) is compiled into System.Net.Http.dll.
It does not make sense to support incremental builds for the simulator (since
no AOT compilation is done), it just makes the test matrix more complicated.
So simplify things by removing support for incremental builds.
We also ignore any (other) --assembly-build-target arguments, because building
to frameworks doesn't make sense either in the simulator.
https://bugzilla.xamarin.com/show_bug.cgi?id=55712
This dramatically decreases the size of watchOS apps built for debug when
using frameworks, because it ends up removing all the bitcode from
Mono.framework.
https://bugzilla.xamarin.com/show_bug.cgi?id=55256
Of particular importance is if we're building for LLVM or not: this fixes a
bug where we wouldn't pass --llvm to the AOT compiler when compiling
assemblies to frameworks (which we do when sharing code).
https://bugzilla.xamarin.com/show_bug.cgi?id=55555
* Remove the MT0008 test, since the error will never be shown again.
* Check non-existent root assemblies and report MT0018 instead of MT0007 if
they look like command-line arguments.
* Collect all MT0018/MT0007 errors before reporting any of them.
We want to copy the aot data for both the 32-bit and the 64-bit versions of an
assembly even if the 32-bit and 64-bit versions of the assembly are identical.
https://bugzilla.xamarin.com/show_bug.cgi?id=54499
Warn if mtouch loads an assembly from a different location than requested
(which might be because there are multiple assemblies with the same name).
Also rework the MT0023 check a bit by explicitly loading the root assembly
first, and then detecting if any loaded assemblies matches the root assembly.
This results in code that's a bit more obvious, and it also works correctly
with extensions (previously the entire MT0023 check was skipped for
extensions).
This makes dylibs automatically have the correct dylib id, which means no
fixups are required.
For instance: we'd build libpinvokes.armv7.dylib from libpinvokes.armv7.m,
which by default ends up with a dylib id of "libpinvokes.armv7.dylib". With
this fix no change is required, since we now build armv7/libpinvokes.dylib
from armv7/libpinvokes.m.
Make the architecture a suffix instead of infix for aotdata filenames so that
it's easier to compute the filename from the assembly name without passing
printf-style format strings around.
Create a custom AssemblyCollection class that contains a dictionary with
assembly identity (name) -> Assembly mapping.
This also means that we can detect if we end up loading multiple assemblies
with the same identity, and show an error in that case (even if that case
should never happen since we cache assemblies based on the identity, it's nice
to have code that ensures it).
Sometimes, when the stars align, fastsim can build an app in less than a
second.
Coupled with the fact that HFS+'s filestamp resolution is 1 second, we can't
assert that filestamps change without making sure enough time passes by.
So sleep for a second.
https://bugzilla.xamarin.com/show_bug.cgi?id=47696
We disabled fastdev for tvOS/watchOS projects with binding projects in
bac02538, and that broke the FastDev_LinkWithTest:
Errors and Failures:
1) Test Failure : Xamarin.MTouch.FastDev_LinkWithTest(TVOS)
Binding symbol not in executable
Expected: no item String ending with " T _theUltimateAnswer"
But was: < ... >
So adjust the test to match the new behavior.
Use @rpath instead of @executable_path in dylibs, since it allows us to be
more flexible when placing dylibs in the app.
In particular with this change it's trivial to put libmonosgen-2.0.dylib in
the container app, and reference it from extensions.
HFS timestamp resolution is 1 second, which means that we can't distinguish
files modified again within 1 second. This means that this test will fail more
often the faster we make mtouch, so add a forced sleep to make sure we don't
do things faster than the file system can keep track of.
Performance tests
-----------------
This is for a new watchOS extension project, built for release.
* The default (currently -O2) optimizations: 41s ( baseline ) 30.027.060 bytes ( baseline )
* All optimizations disabled (`--llvm-opt=all=`): 17s (-24s = -59%) 32.978.312 bytes (+2.951.252 = +10%)
* Optimized for size (`--llvm-opt=all=-Os`): 36s ( -5s = -12%) 28.617.408 bytes (-1.409.652 = -5%)
* Optimized for more size (`--llvm-opt=all=-Oz`): 35s ( -6s = -15%) 28.601.016 bytes (-1.426.044 = -5%)
* Optimized slightly (`--llvm-opt=all=-O1`): 35s ( -6s = -15%) 28.666.556 bytes (-1.360.504 = -5%)
* Optimized a lot (`--llvm-opt=all=-O3`): 41s ( 0s = 0%) 30.403.996 bytes (+ 376.936 = +1%)
Conclusions
-----------
* The fastest build by far (less than twice as fast) is if optimizations are
disabled, but this adds a 10% size penalty (~3 MB in this test case),
compared to the baseline, and 15% size penalty (4.3 MB) compared to -Oz.
* -Oz seems to have the best overall results: at least as fast as any other
optimized build, and the smallest app as well.
Caveats
-------
Some optimizations might not work the AOT compiled code. The resulting
binaries have not been tested.
Event sequence:
* mtouch is executed with the linker disabled.
* The linker pipeline copies all input assemblies (since the linker is
disabled the assemblies don't change) into the PreBuild directory. This will
keep the original timestamps of the input assemblies.
* mtouch is executed again, when none of the input assemblies changed.
* The linker pipeline will re-execute, because it will see that at least one
of the input assemblies (at least the .exe) is newer than at least one of
the assemblies in the PreBuild directory (usually a framework assembly,
because those have the original timestamp from their install location).
Fix:
Touch all the assemblies in the PreBuild directory after the linker pipeline
executes the first time. This way the second time mtouch is executed, it will
find that all assemblies in the PreBuild directory have timestamps later than
all the input assemblies, so it will load the cached linked assemblies,
instead of re-executing the linker pipeline.
* [mtouch] Always require a SDK version when building.
Technically it was required before too, but the error messages were non-optimal:
it could for instance complain that the user is using an iOS framework that
was introduced in iOS 2.0.
* [mtouch tests] Rewrite MT0060 and MT0061 tests to use MTouchTool.
This makes sure we pass --sdk to mtouch (which MTouchTool does by default), so
that we don't run into MT0025 before the errors we're testing for.
The BundleId property is used by the code that generates the mSYM directory,
but its value was always the default value 'com.yourcompany.sample' instead of
looked up in the app's Info.plist.
So fix the BundleId property to do the expected.
Also fix the mSYM test (SymbolicationData) to actually test mSYM stuff (it was
partially disabled when we disabled automatic mSYM generation for C8, and
never re-enabled), and port it to the new and better test syntax, and add a
few more asserts to check the manifest.xml generation.
-lsqlite3 is a linker flag, not a file to be linked with, so when
automatically determining that we need to pass -lsqlite3 we need to put it in
the right list of linker information.
Otherwise we may end up passing `-force_load -lsqlite3` to the linker (if the
assembly's ForceLoad flag is set), which won't compile.

dontlink/64-bit release times out on our Sierra bots, so try to bump the
timeout to see if this is working on other bots because those other bots are
faster.
* [jenkins] Add support for enabling device builds using labels.
* [xharness] Give the iOS MSBuild tests 30 minutes to finish.
* [mtouch tests] Give the BuildTestProject 10 minutes to compile each test case.
Wrench bots build the dontlink test in ~3m40, but that's apparently not enough
for the Jenkins bots (slower bots?), which time out the test after 5 minutes.
So double the timeout to 10 minutes, which will hopefully give the Jenkins
bots enough time to run the test to completion.
Convert MT1016 and MT1017 to newer test syntax, and at the same time change
them to not disable the managed linker.
For these tests it doesn't matter if they're linked or not, but linking is
much faster (20s vs 82s for both tests).
In 7c6d04f1 the code to create the NOTICE file was simplified, and the new
implementation is writing to a temporary file and then replacing the existing
file.
This makes the scenario that MT1017 was testing (failure if a readonly NOTICE
file already exists) go away, since we don't write to the existing file
anymore (so the build succeeds).
Earlier versions of Xamarin Studio stored an invalid http message handler in
watchOS project files, which would cause a build error. In addition Xamarin
Studio removed the UI to set the http message handler (since only one value is
valid), which meant that the user had to edit the project file by hand to get
around this build error.
So make it a warning instead (and document what the user has to do to fix the
warning).

Update mdb files even if the corresponding assembly didn't change, because the
mdb can change even if the assembly didn't (if whitespace was modified in the
source code, causing code lines to move).

Native libraries are already linked into the dylib for the binding assembly,
which means that if we also link it into the main executable, the native code
ends up twice in the app (which is bad for many reasons).

The container app may not reference the same third-party frameworks as
extensions, which means that we must make sure the extension's frameworks are
also included in the app bundle.
So when building extensions save a list of all third-party frameworks, and
then read that list and include those frameworks when building the main app.

This makes it possible to set linker flags per assembly:
[assembly: LinkWith (LinkerFlags = "-lsqlite3")]
Which is required when incremental builds is enabled and a particular assembly
needs special linker flags (because we don't propagate the global -gcc_flags
to each dylib we build when doing incremental builds).
Also add an option to set the dlsym mode for an assembly (using the LinkWith
attribute).
* [mtouch/tests] Add TimingTests
- New MLaunchTool.
- AppLaunchTime (mlaunch): time to launch an application on the simulators.
How it works: we first open the simulator by launching a dummy app. This allows us to detect if there are any launch watchdogs.
Therefore, for consistency, all measurements are done with the simulator already open.
In the case of the AppLaunchTime test, we build the app with the default config and launch it. It's automatically killed by the simulator
because it does not have a valid entry point but this is fine because it also kills the process and lets us stop the stopwatch.
We then simply log the time performance.
In 9d4be4c we started building fat applications when building for device in
our test projects. That causes the BuildTestProject to take twice as long,
thus hitting a 5 min timeout value, causing the test to fail.
So change the test to the previous behavior: we were only building test
projects for ARM64 previously, so do that.
Fix NullReferenceException in PInvoke wrapper generation when incremental
builds are enabled and the linker didn't run because cached results were
found.
