[threads] Enter GC Unsafe before pumping HP queue in unregister_thread (mono/mono#15890)

If the thread info TLS key dtor runs unregister_thread from a foreign thread
and we have work in the hazard pointer queue, we need to first switch to GC
Unsafe mode because some of the free methods passed to
mono_thread_hazardous_try_free need to be coop-aware.

Also, added checked mode assertions that conc_table_free and
jit_info_table_free are called from GC Unsafe mode.

Fix race condition and use less memory in mono_lookup_icall_symbol. (mono/mono#14532)

It is racy because it is doing on-demand initialization, which is often racy.

The rewrite changes the result to be one pointer, atomically swapped, which implies a full barrier and data dependency, so no race.

It could also be fixed by copying and sorting an array of pairs, and one pointer to that.

However in order to save memory I instead use indirect data that is an array of uint16 pointing into the original data. That is a slight memory vs. time tradeoff.

Yes there is debugging code left, under #if, that I prefer to leave, both as evidence that I tested it, and to make it somewhat but ideally testable in future.

The code also was using an unnecessary somewhat risky but probably ok here way to compare pointers, that I fixed.

As well the result is marginally smaller and faster because it was inlining something like bubblesort, now reuses qsort.

The failure is happening when we are doing mono_class_setup_fields ("BaseClass<T>") which needs to decide for each field whether it is blittable or not. So therefore we are trying to decide if ValueTest<T> (that is: the ValueTest<U> field inside BaseClass<T>) is blittable or not.

So we instantiate U with T.
Now to decide whether VaueTest<T> is blittable or not, we look at every field.
So then we look at T value.
To decide if T is blittable we first check if it's a reference type.

That check is currently inadequate for generic parameters - what the PR adds is the ability to see if theres a T : class constraint or a T : C constraint - where C is some class. As soon as we know that T's constraint will force it to be a reference type we can definitely say that T won't be blittable without having to initialize C, at all.

Previously, Mono would see that T is some kind of type for which it couldn't definitively decide that it's a reference type and it would call: mono_class_setup_fields (field_class) which would then try to setup the fields of the parent class BaseClass<T>. And that would hit the recursion check.

[sre] Make creation of dynamic method synchronized

Before, reflection_create_dynamic_method could end up being called by two threads simultaneously. At the end of the method the ilgen field of the MonoReflectionDynamicMethod object is cleared, to enable its collection since it is no longer needed. The problem with this is that it can confuse the other thread compiling the dynamic method, making it see that there is no body.

We could either bother making this clearing work with multiple threads (and I'm not 100% convinced that the rest of the code is thread safe), disable the clearing of ilgen (which would make us use more memory) or go with the simple approach of locking on this DynamicMethod so only one thread is compiling it at one time.

[ios] Switch to python offset tool (mono/mono#15744)

The C# version doesn't work on 64bit. It would require to update its dependencies, but Zoltan already added a Python version for WebAssembly which works fine.

Some notes:
* changed the semantics of `--xcode-path` in order to match the output of `xcode-select -p`
* switched to python3/pip3
* removed hack for arm64_32, it works properly now because the Python version uses stock `clang`
* removed some leftover usages of `XCODE32_DIR`.

Manually verified by comparing output with the C# version.

This will unblock the iOS team when building on Catalina/Xcode11, as they can't consume SDK archives there. See https://github.com/xamarin/xamarin-macios/pull/6603#issuecomment-512803082

[interp] Use correctly-sized writes and reads in Unsafe.AddByteOffset and Unsafe.ByteOffset

The truncated store to the top of the stack in`MINT_INTRINS_UNSAFE_BYTE_OFFSET` could cause the upper bytes of the address used as the first argument to `ByteOffset` to linger, yielding inaccurate (and usually excessively large) offsets on systems where `sizeof(void *) > sizeof(guint32)`; this made
`System.Text.Unicode.Utf8Utility.GetPointerToFirstInvalidByte` return nonsense results.

The truncation in `MINT_INTRINS_UNSAFE_ADD_BYTE_OFFSET` hasn't, as far as I know, caused any test failures. But `AddByteOffset` takes an `IntPtr` as its second argument, not an `int`.

Aleksey Kliger (λgeek) [Wed, 17 Jul 2019 21:35:15 +0000 (17:35 -0400)]
[loader] Add MonoAssemblyLoadContext; stop sharing MonoImages on netcore (mono/mono#15527)

Implement a couple of things:

1. Add a `MonoAssemblyLoadContext` opaque struct
2. On netcore Mono, use it to keep track of  which `MonoImage`s are loaded.  (Addresses part of mono/mono#13891)

In a bit more detail:

- Add a `MonoLoadedImages` struct to hold the hash tables that we use for checking if a `MonoImage` is already loaded
- Add an opaque `MonoAssemblyLoadContext` typedef
- (Framework Mono) Add a `get_global_loaded_images()` function to get the shared `MonoLoadedImages`
- (netcore Mono) Add a `MonoAssemblyLoadContext` struct that owns a `MonoLoadedImages` and add a `default_alc` member to `MonoDomain
- Pass a `MonoAssemblyLoadContext*` to most `MonoImage`-loading functions - on Framework Mono its usually NULL and we fall back to the global loaded images, on netcore Mono it's usually `domain->default_alc->loaded_images`
- (netcore Mono) Create a default Assembly Load Context when a `MonoDomain` is created
- Add a `MonoAssemblyLoadContext*` field to `MonoAssemblyLoadRequest` and pass an ALC in a few places.

---

Remaining work:

(netcore Mono) There are still places where a `MonoAssemblyLoadRequest` or a `MonoAssemblyOpenRequest` has a `NULL` ALC - those will need to be tracked down and fixed.

(netcore Mono) Eventually `MonoAssemblyLoadContext` should keep track of the loaded `MonoAssembly`s, not just images.  One goal on netcore Mono is to ifdef out `MonoDomain:domain_assemblies`.

---

* [loader] Add a MonoLoadedImages struct to own the MonoImage sharing

   Initially, there's just a single global set of loaded images.

   Once we have AssemblyLoadContext support, each ALC will have a separate set.

   NOTE:
     - Some of the existing Mono API is difficult to support with this design
       since it assumes each MonoImage is loaded at most once.

* [loader] Add a MonoAssemblyLoadContext member to MonoImage for netcore

* [loader] Unregister image from its owner when closing

* [loader] Pass MonoLoadedImages to register_image

* [domain] Add mono_domain_default_alc and mono_alc_get_loaded_images

* [loader] Add an AssemblyLoadContext argument to mono_image_loaded_internal

* [metadata] Add mono_image_get_alc ()

* [loader] Pass MonoAssemblyLoadContext to mono_image_open_from_data_internal

* [loader] Pass MonoAssemblyLoadContext to mono_image_open_from_module_handle

* [loaded] Pass MonoLoadedImages to mono_image_open_a_lot_parameterized

* [loader] Pass MonoAssemblyLoadContext to mono_image_open_a_lot

* [runtime] Mark mono_image_open_full external only

   Runtime should use mono_image_open_a_lot.

* [runtime] Mark mono_image_loaded_by_guid external only

   Also mark mono_image_loaded_by_guid_full external only

   Runtime will need some (as yet unwritten) mechanism that takes a MonoAssemblyLoadContext as an argument.

* [domain] Create a default ALC for each MonoDomain

* [netcore] Pass default ALC in mono_core_preload_hook

   If the assembly name matches a trusted platform assembly, open it in the default ALC of the root domain

* [mini] Open main assembly in default ALC in the root domain

* [netcore] Don't define get_global_loaded_images()

   Every assembly load request should come from an assembly load context.  Each ALC has a set of loaded images.  So we should never need a global list.

   With this PR, we no longer share MonoImages across distinct ALCs.  So in principle, each ALC can open the same assembly but resolve its references in different ways.

   Fixes part of https://github.com/mono/mono/issues/13891

* [runtime] Mark mono_pe_file_open external only

* [loader] Pass MonoAssemblyLoadContext to mono_image_open_raw  and mono_image_open_metadata_only

* [loader] Pass MonoAssemblyLoadContext to do_mono_image_open and set MonoImage:alc

* [loader] Add version 2 of assembly preload hook

   Pass MonoAssemblyLoadContext through the preload hook.  This is used in mono_assembly_request_byname_nosearch which, in turn, is called by load_reference_by_aname_default_asmctx which is used to resolve references from one assembly to another.

* [netcore] Pass native ALC ptr to AssemblyLoadContext.InternalLoadFile

* [netcore] Implement AssemblyLoadContext.InternalInitializeNativeALC

   also implement mono_domain_create_individual_alc ()

* [netcore] Pass ALC to System.Reflection.Assembly.InternalLoad

   Pass the domain default ALC to mono_assembly_load ()

   Also pass MonoAssemblyLoadContext to mono_assembly_load_full_gac_base_default ()

* [loader] Implement MONO_LOADED_IMAGES_ASSEMBLY properly

   Store the MonoLoadedImages for netmodules in the MonoImage for the main image of an assembly.  This is also used by SRE - the dummy module of the AssemblyBuilder has the loaded_images that contains the ModuleBuilders.

* [loader] Use global_loaded_images for netmodules with framework Mono

   The new stuff is only for ALC support in netcore

* [loader] Drop netmodule support in MonoAssemblyLoadContext

   netmodules are not supported in netcore

* [loader] Spin out image hashing out of image.c

   Move MonoLoadedImages support code to loaded-images.c loaded-images-global.c and loaded-images-netcore.c

Also spin out assembly-load-context.c for MonoAssemblyLoadContext functions

* Move ALC icall to assembly-load-context.c

* formatting fix

* [msvc] Add new files to .filters

* update comments

* [image] Change mono_loaded_images_remove_image to decrement the refcount

Decrement the refcount and remove the image from the loaded images hashes in
one place.  Change mono_loaded_images_remove_image to return TRUE if the rest
of image unloading should proceed or not.

[llvm] avoid FP elimination on iOS/armv7

Instead of
```
push    {r4, r5, r6, r7, r10, r11, lr}
```

LLVM will generate
```
push    {r4, r5, r6, r7, lr}
add     r7, sp, mono/mono#12
push    {r9, r10}
```

Seems like this https://github.com/mono/llvm/commit/mono/mono@a04e9e4a0af16f15ace258e81448b7eeca5ff599 assumes that `-disable-fp-elim` is passed for iOS targets. I wondered why this wouldn't break things for them, but when you run `clang` from Xcode with `-v`, you will discover that its driver passes `-mdisable-fp-elim`.

Together with https://github.com/mono/llvm/pull/48 this fixes crashes with FullAOT+LLVM on iOS 32bit.

Misc AIX/PASE tweaks (mono/mono#15651)

* Partial enablement of alternate stack for AIX/i

It turns out much like macOS, AIX doesn't like to do mprotect/valloc
for the first thread's guard pages, so skip those. It seems mostly
fine except for one or two crashes causes it to grab the wrong IAR
and deadlock dumping memory. As such, leave the code and configure
script override to disable in place, just change the comment and
add support code.

* Use Qp2getifaddrs on PASE

Not sure if proper way to implement. Reuses getifaddrs code as much
as possible, since it's merely a name change based on the docs, due
to it being namespaced in case AIX gets it or something.

I'm not sure how many of these codepaths still work properly;
one had a questionable order of ifdef.

This will eventually prepare for CoreFX NetworkInterface, so test
it here.
