lateralusX/lateralusX/windows-native-unwind-codeview-support
[Windows] Windows x64 full AOT native unwind info support.

mono_remoting_wrapper (), its not needed since mono_remoting_wrapper () is called through a wrapper.

otherwise we off-by-one overflow and smash other things
|
|
|
|
In the C parser check for empty at the outset.
In the managed parser, copy an empty string component to the built-up TypeSpec
and handle it in the Type.GetType (..., asmResolver, typeResolver) implementation
|
|
Mark mono_reflection_parse_type as external only. Runtime should use the
_checked version.

scanning function as such
ASan has very few false-positives, quoting the ASan documentation
(https://github.com/google/sanitizers/wiki/AddressSanitizer#turning-off-instrumentation):
> In some cases a particular function should be ignored (not instrumented)
> by AddressSanitizer:
>
> [...]
>
> * Ignore a function that does some low-level magic (e.g. walking through
> the thread's stack bypassing the frame boundaries).

Fixes #59080

Assume you have something like this:
```
$ cat invokecrasher.cs
using System;
using System.Reflection;
public class InvokeCrasher {
readonly static object[] default_args = new object[1] { new string[] {} };
public static void Main (string []args) {
Assembly assembly = Assembly.LoadFile ("crasher.exe");
try {
assembly.EntryPoint.Invoke (null, default_args);
} catch {
}
assembly.EntryPoint.Invoke (null, default_args);
}
}
```
```
$ cat crasher.cs
using System;
public class Crasher {
unsafe public static void Main (string []args) {
int i = 1337;
CrashMe (&i);
throw new Exception ();
}
unsafe static void CrashMe (int *p) {
// p = (int *) 0;
*p = 0;
}
}
```
On the first `Invoke ()` the interpreter goes through `ves_pinvoke_method`:
```
interp_push_lmf (&ext, frame);
mono_interp_enter_icall_trampoline (addr, margs);
interp_pop_lmf (&ext);
```
The LMF is needed for unwinding by mini. In this situation though,
`Crasher` throws an exception and goes through the exception handling machinery
of the interpreter which leads to missing out of the `interp_pop_lmf ()` call.
On the second `Invoke` we would therefore push the same address as an LMF
again, which leads to a LMF that points to itself as `previous_lmf`. If we
encounter a native crash in this state (as hinted with `p = (int *) 0; *p = 0;`),
the unwinding machinery would end up in an infinite loop.

value types can contain references, and therefore GC write barriers are
required.

It'd fail to find System.Runtime.dll and System.ValueTuple.dll.
Changed the csi.rsp to include those from the Facades/ dir and added a test.

[profiler] Clean up the makefile and address some issues with it.
* Don't link the profilers to libmono, except on mobile.
* The coverage profiler doesn't use zlib. Don't link to it.
* Fix the LIBADD variable for the VTune profiler.
* Add some comments for certain non-obvious aspects.
* Some style cleanup.
Also introduce a HOST_IOS variable in the build system which covers iOS, watchOS, and tvOS.

Update Bockbuild

https://github.com/mono/mono/pull/5680 added mmap/sendfile prototypes
but we should only use those when ANDROID_UNIFIED_HEADERS is defined
to avoid getting errors like:
```

It was writing to the current working directory before which
doesn't work on platforms where that directory is read-only.
Using the same setup/teardown methods as TypeBuilderTest we
instead create a directory in the temporary location and put
the files there.

Emit very basic codeview information into full AOT builds on Windows x64. The codeview information is far from complete and
is currently just initial work needed to get function symbol names to appear in native callstack that includes managed functions.
Described functions does not include parameters, local variables or line info at the moment, but could be extended in the future.
Fix also make sure linker will emit PDB files including information that can be picked up by debuggers. It is possible to disable
codeview info by passing "nodebug" to AOT compiler, this will also disable the generation of PDB files, if a DLL would have been build.

Emit needed sections when building Windows x64 full AOT targeting Clang for MS codegen in order for linker to
include entries in process unwind tables for full AOT:ed managed functions and trampolines. Implementation also includes
a cache used to minimize the number of duplicated unwind data section in each object file, reducing final image size.

Bump corefx
|

On the CLR, two enumerators containing zero elements will
have reference equality if they are inflated with the same
generic type.
If comparing two enumerators which are not inflated (Array.Empty, for
instance), they are not equal when they contain zero elements.
This reference equality behavior is not compatible with treating
the enumerators as structs, as value types will not have reference
equality.

Apple states clearly in their documentation about SecTrustResult.Proceed [1]:
The user explicitly chose to trust a certificate in the chain (usually by
clicking a button in a certificate trust panel).
Your app should trust the chain.
This fixes bug #[58411][2], where SecTrustEvaluate returns
SecTrustResult.Proceed starting with iOS 11.

regression caused by 9302c31f81abd2f5bbf9a8ddd27993e1ece55db2. Fixes #59832. (#5686)

* [runtime] Avoid collecting coverage data for wrappers.
* [runtime] Return sensible information for methods which have no coverage info in mono_profiler_get_coverage_data ().
* [profiler] Emit coverage info for uncovered methods as well.

after the code for CEE_JIT_ATTACH, since the init code can make calls to methods like memset () which can go through the trampoline code. Fixes #59182. (#5678)

* Add new profile for monodroid tools
This allows the XA build to use these instead of needing to build net_4_x.
We build the assemblies against the .NET 4.6 reference assemblies.
* Skip monodroid_tools in verify (aka mcs-compileall)
Exclude it from the test_profiles since running tests makes no sense there.
Also refactor to exclude binary_reference_assemblies as well,
it was already excluded manually in mcs-compileall before.
|

TestHelper was previously excluded because the XA tests weren't built
as part of Mono but rather as part of XA test suite which included
its own version of the helper. Now, however (https://github.com/xamarin/xamarin-android/commit/e9daf5ea35709ce1bc6ba81c7c37d72d385bace2),
XA uses BCL+friends test assemblies built by Mono itself and so
we need to restore TestHelper in the build.

It fails on some systems otherwise. The other tests already had this check.
