Visual Studio reported that they were seeing unnecessary func-eval aborts. This was due to a lock ordering issue between CrstReadyToRunEntryPointToMethodDescMap and the coop mode transition. Flipping the ordering should fix the issue for this particular lock though it doesn't prevent any other lock from blocking func-evals. This should reduce, but not eliminate, the number of cases where func-eval abort is required.

* Enable NuGet Audit and fix issues Microsoft.NET.HostModel can reference the live builds of the packages it depends on. These will be deployed by the SDK.� Most other audit alerts were due to tasks pulling in old dependencies that aren't even used by the task. Avoid these by cherry-picking just the assemblies needed by the tasks and provided by MSBuild / SDK. This prevents NuGet from downloading the package closure with the vulnerable packages. We don't need those packages since the tasks aren't responsible for deploying them. A better solution in the future would be a targeting pack for MSBuild and the .NET SDK - so that components that contribute to these hosts have a surface area they can target without taking on responsibility for servicing. There is once case where we have a test that references NuGet.* packages which also bring in stale dependencies that overlap with framework assemblies. Avoid these by cherry-picking the NuGet packages in the same way. * Fix package path on linux * Only use live JSON from HostModel SDK pins S.R.M and a few others, so don't make them upgrade yet. * Add a couple missing assembly references * Refactor tasks dependencies Consolidate representation of msbuild-provided task dependencies * Fix audit warnings in tests * Remove MetadataLoadContext from WasmAppBuilder package * Update Analyzer.Testing packages * Reduce exposure of Microsoft.Build.Tasks.Core * Fix audit warnings that only occur on browser * Update Asn1 used by linker analyzer tests * React to breaking change in analyzer test SDK * Enable working DryIoc tests * Fix double-write when LibrariesConfiguration differs from Configuration * Fix LibrariesConfiguration update target * Clean up references and add comments. * Make HostModel references private This ensures projects referenced will not be rebuilt by tests. This also means the HostModel package will not list these as references, but that's OK since the SDK provides them and this is not a shipping package. * Use ProjectReferenceExclusion to avoid framework project references On .NETCore we want to use the targeting pack and avoid rebuilding libs. * Update src/libraries/System.Runtime.InteropServices.JavaScript/tests/JSImportGenerator.UnitTest/JSImportGenerator.Unit.Tests.csproj Co-authored-by: Jeremy Koritzinsky <[email protected]> --------- Co-authored-by: Jeremy Koritzinsky <[email protected]>

…#108289) Work around dotnet/msbuild#9152 Possibly fixes dotnet/runtime#107936

We used to stackalloc a lot of data because the Target callback had to be an UnmanagedCallersOnly function pointer. But now it's just a delegate. So we can heap allocate the mock memory space and get rid of a bunch of incidental fixed statements We used to spell out the JSON contract descriptor in every test case. We dont' need to do that - most tests are not testing parsing. Hide all that stuff in MockMemorySpace.Builder * make MockMemorySpace.ReadContext a class Now that Target's reader callback is just a normal managed delegate, we don't have a lot of reason to make the testing ReadContext a ref struct. So simplify our resource usage and just store the descriptors and json as heap allocated arrays * remove uses of fixed in tests The ReadContext for the tests keeps a copy of the json payload, we don't need to use unmanaged pointers * make the MockMemorySpace.Builder a normal class we don't hold pointers to span data anymore * make MockMemorySpace.ReadContext private * begin hiding ContractDescriptorFill most of our tests that use a valid contract descriptor don't need to repeat the boilerplate to fill it in * start removing json and pointer data boilerplate * Don't fill the pointer data when there isn't any We previously did the wrong thing with TargetTestHelpers.MakeGlobalJson: it always filled in direct values. So technically filling in the pointer data in all the other tests is unnecessary. Add a second SetGlobals overload for the builder that takes a 4-tuple (either ulong? Value or uint IndirectIndex) and a second collection of actual values for the indices. * remove unused MockMemorySpace.Builder functions everything is using high level construction now * remove unneeded stackalloc * describe test addresses

reviously we used EmbeddedResource to collect the contract descriptor baselines into cdac-build-tool and we also embedded the C source template. But we only ever run cdac-build-tool during the runtime build - the files are in the same source tree. Just pass their paths when invoking the tool, don't embed them. Fixes #107958 * don't embed baselines into cdac-build-tool * don't embed the template source file in the tool

* Remove HelperMethodFrame from Delegate construction

Root the System.Runtime EventSource The System.Runtime EventSource (RuntimeEventSource), was unintentionally being garbage collected because it wasn't rooted. This caused runtime EventCounters to no longer be available after GC occurred. This was a regression from a recent change (dotnet/runtime#106014). That change accidentally converted the static field that was intended to the root the object into a property getter that returned a new instance each time it was called. This fix converts the property back to being initialized only once. This will fix #107919 once it is backported. Co-authored-by: Tarek Mahmoud Sayed <[email protected]>

The main aim of this change is to remove the block reference from AddCodeDsc, as it can become stale over time, making it impossible to determine where a throw helper block should be placed, if we have subsequently eliminated EH regions. Instead we use the try/handler indices plus a bit of extra info to track where the throw helper block should be placed. I also moved the key formation logic nearby and reworked it a bit, and gave the AddCodeDscs debug indices for dumps. This should unblock doing late EH region removal.

Fixes #72909. Internal team ran into this. Turns out CsWinRT also needs this, but they're were working around instead pushing on a fix. The big problem with this one is that we have an interface call to a default interface method that requires generic context. This means we need some kind of instantiating thunk (since callsite didn't provide generic context because it didn't know it). The normal default interface case uses an instantiating thunk that simply indexes into the interface list of `this`. We know the index of the interface (we don't know the concrete type because `T`s could be involved), but we can easily compute it at runtime from `this`. The problem with `IDynamicInterfaceCastable` is that `this` is useless (the class doesn't know anything about the interface). So we need to get the generic context from somewhere else. In this PR, I'm using the thunkpool as "somewhere else". When we finish interface lookup and find out `IDynamicInterfaceCastable` provided a shared method, we create a thunkpool thunk that stashes away the context. We then call the "default interface method instantiating thunk" and instead of indexing into interface list of `this`, we index into interface list of whatever was stashed away. So there are two thunks before we reach the point of executing the method body.

Make `bbID` available in release builds, and use it to control the order of edges in the pred list. This removes (almost all) the need for reordering pred lists when blocks are renumbered (`bbNum` changes, but `bbID` doesn't). Also remove the need for sorting pred lists; in the one remaining place where sorting might be needed, just remove, modify, and then re-add the edge.

Break up the monolithic cdacreader assembly into four parts: 1. `Microsoft.Diagnostics.DataContractReader.Abstractions` just the API surface for contract implementations and clients. **Note**: everything is internal for now (with IVT for the other assemblies) - we're not committing to a public API surface yet 2. `Microsoft.Diagnostics.DataContractReader.Contracts`: the concrete implementations of the contracts and data 3. `Microsoft.Diagnostics.DataContractReader`: a concrete Target that ties everything together 4. `cdacreader`: just the unmanaged entrypoints and the legacy DAC API surface `SOSDacImpl` To untangle things I had to add a new `IContractFactory<TContract>` interface - this is what the target's ContractRegistry uses to instantiate specific versions of contracts. Goals: * Make it possible to mock a Target and its ContractRegistry so that concrete contracts can be tested in isolation for example by making dummy dependent contracts that return canned answers. * Eventually make it possible to inject additional contract implementations into a ContractRegistry implementation Make it possible to consume just the Target and Contracts without the unmanaged entrypoints or the legacy interfaces Changes: * [cdac] break up cdacreader into 4 separate assemblies * rename the contract factories using libraries naming convention * removed unused usings * document all abstract Target members * rename Target -> ContractDescriptorTarget * Add ReadTargetPointerFromSpan to abstract Target Allows the TypeNameBuidler and SigFormat to depend on the abstract target * change SOSDacImpl to depend on the abstract Target * fixup filenames and namespaces

These had to be excluded in #108235 but #108328 fixed them in the meantime. One of these PRs might be serviced for .NET 9 and the other may not, so I'm just reenabling this in a separate PR to make backports easier.

This code was trying to answer question: "Was this method overriden by something else in a more derived class"? It was walking the base hierarchy in canonical form, but that was leading to methods not resolving at all. The fix is to walk the non-canonical hierarchy and canonicalize after we resolved everything. I ran into this in #108379 that unlocked more whole program devirtualization and `StringSearchValuesBase` is in this shape.

Update JIT and runtime to devirtualize interface calls on arrays over non-shared element types. Shared types are not (yet) handled. Add intrinsic and inlining attributes to key methods in the BCL. This allows the JIT to devirtualize and inline enumerator creation and devirtualize and inline all methods that access the enumerator. And this in turn allows the enumerator to be stack allocated in some simple cases. However, the enumerator fields are not (yet) physically promoted, because of an optimization in the BCL to return a static empty array enumerator. So the object being accessed later is ambiguous. Alse ensure that since GDV resolves the virtual call twice, and expects to get similar results both times, things work for the array case by keeping track of the initial devirtualization inputs. Progress towards #62457.

Defer funclet separation until after we've run the optimization phases. This is a prerequisite for introducing a late EH opts phase that will remove now-empty finallies or faults. Also update `fgNewBBAtTryRegionEnd` so that the new block's enclosing region is the try, not some handler region nested within the try (we see this case now during loop canonicalization, because we haven't yet moved the handlers).

AddCodeDscs are currently kept in both a linked list and in a hash map. Since the order of these descriptors is not important, remove the list and use map iterators to enumerate them. This makes it easier to remove ACDs.

* Improve software exception handling performance I have recently discovered that large part of the time spent in the EH while handling software exception is in the RtlLookupFunctionEntry Windows API. That API is called when unwinding native (non-managed) frames on stack. The current implementation of the IL_Throw JIT helper that is used to throw managed exceptions needs three unwinds to get to the managed caller. Due to the two passes of EH, it means there are six calls made to that API per throw. This change reduces that to just a single unwind, which leads to about 12% improvement in single threaded scenarios and about 30% improvement in multi threaded one for a case when an exception is thrown over 10 managed frames and then caught. It also leads to similar improvements in async exception handling performance. On Linux, the multi-threaded gain is much higher, I've measured 3 fold improvement. An additional benefit of this change is removal of the helper method frame from IL_Throw and IL_Rethrow, which contributes to the current effort of getting rid of the helper method frames. I have made this change for the new EH only.

Fixes an incorrect member reported for warning due to RUC member kept by new constraint. Also adds a testcase for dotnet/runtime#108507, but doesn't fix that issue.

Cecil represents modreq/modopt in signatures as part of the TypeReference (using subclasses RequiredModifierType/OptionalModifierType). We need to unwrap these to get the correct behavior in IsNamedType. This fixes the `IsTypeInterestingForDataflow` check for modreq/modopt types (`Type modreq(IsVolatile)` should be considered interesting for dataflow, and `Type[] modreq(IsVolatile)` should not). Includes a similar fix for function pointers.

… (#108498) Similar to dotnet/runtime#81864, fields in a RUC class are producing trim analysis warnings in the OOB trim step (the mentioned issue was specific to library mode, but it's also a problem for the normal root assembly mode). This extends the fix from dotnet/runtime#84620 to avoid producing warnings for fields that are marked just because an assembly was rooted. Arguably rooting an assembly _should_ warn about rooted RUC members, but that's not the case today for RUC methods, so this makes the behavior consistent for fields. --------- Co-authored-by: Jackson Schuster <[email protected]>

… x64 Windows (#108538) - Handle x86 on x64 looking for x64 install so that it looks at `ProgramW6432` instead of `ProgramFiles` - Just check `ProgramFiles` for when determining location for current arch - We were unnecessarily checking `ProgramFiles(x86)` for x86 running in wow64 Because this is looking at machine-wide locations, our tests don't actually go down this path (tests for default install location go through a test-only environment variable which bypasses the ProgramFiles environment variables lookup).

SCEV analysis would allow stores either via simple add-rec handling or by forwarding to the data of the store.

Switch the analysis to return nullptr for stores; instead add handling for `GT_PHI` in the places where it was needed.

There's also no way to _not_ use LKG bits. That's left as future work.

…(#108411) Resolves policheck issue around the wording

Fixes #108608. To simplify EH maintenance logic, leave EH regions in a deconstructed phase during block reordering, and correct the end block pointers of each region in a pass over the block list after. By walking the list backwards, we can short-circuit finding the end of each region, and we don't run into the issue of an EH region not being able to determine if it's at the end of its parent region due to some awkward placement of a sibling region.

This test was disabled on windows-arm64, but the outerloop also fails on linux-arm64. See dotnet/runtime#104927

Part of #107749, and follow-up to #107927. When computing a RPO of the flow graph, ensuring that the entirety of a loop body is visited before any of the loop's successors has the benefit of keeping the loop body compact in the traversal. This is certainly ideal when computing an initial block layout, and may be preferable for register allocation, too. Thus, this change formalizes loop-aware RPO creation as part of the flowgraph API surface, and uses it for LSRA's block sequence.

This also makes the BufferSize pattern consistent across all new custom marshallers.

The JIT can sometimes optimize away all the code in a finally or fault, so rerun and generalize the empty try-finally removal to cover faults and run it again after the main optimization passes.

According to the most updated docs, enabled and justification need to be underneath compiled.

this was a regression introduced in #105545. this would only manifest during the beginning of a process when we needed to grow the # of heaps (and can grow) and we haven't done a gen2 GC yet so we set it to doing one. the problem is the check I made did not include the ephemeral GC that may happen at the beginning of a BGC before we set gc_background_running to true. so at the end of that eph GC, we are in calculate_new_heap_count and set trigger_initial_gen2_p to true, not realizing we are already in a BGC. then during the joined_generation_to_condemn at the beginning of the next GC, if our conclusion was still doing an eph GC we'd make it a BGC due to trigger_initial_gen2_p which obviously would cause problem if a BGC is already in progress (I do have an assert for this but we haven't seen this in a dbg build...). the fix is to simply use the right check - is_bgc_in_progress() instead of background_running_p() which includes that eph GC case.

These three methods have a higher overload resolution priority than any potential user defined extension methods `TrimEnd(this string, string)` (et al), but invariably yield a different answer than those extension methods: for an existing call `text.TrimEnd("suffix")` the extension method wants to remove just the suffix, so "prefixinfixsuffix" becomes "prefixinfix". However, our method treats it as a call of `text.TrimEnd('s', 'u', 'f', 'f', 'i', 'x')`, yielding the result "prefixin". An alternative solution to this problem would be to define our own `string.TrimEnd(string)` instance method, but that has its own set of complications and is too risky to consider for backporting into .NET 9. This change only removes the methods from the System.Runtime (ref) assembly, in order to work better with the slightly circular dependency/flow in the dotnet/* repositories.

- Add `src/installer/tests/helixpublish.proj` - Defines correlation payloads (pre-built test targets, .NET install layout, product host binaries, test/mock host binaries) - Sets pre-commands to set environment variables used by tests for test assets and artifacts locations - Generate helix work items for each host test project - runs `dotnet test <host_test_dll>` for each test with the built output as the payload directory - Update `RepoDirectoryProvider` to use `HELIX_CORRELATION_PAYLOAD` (when available) for path to product/test host binaries. This is not hooked up to actually run in a pipeline. I tested by manually kicking off runs by setting environment variables and directly building the new project.

…ct (#108780) * Rename

…(#108772) - `SOSDacImpl` in cDAC implements all the interfaces implemented by `ClrDataAccess` - `CLRDataCreateInstance` returns cDAC if it is enabled - `cdac_reader_get_sos_interface` takes the legacy DAC implementation - Legacy DAC no longer calls into cDAC for its `ISOSDac*` implementations - cDAC delegates to legacy DAC (if it has one) for APIs it has not implemented and asserts that the results are the same for APIs it has implemented Behavioural differences of note: - Since asserts comparing results are in the cDAC instead of DAC now, they will come through as a fail fast with or without a debugger attached - as opposed to before, when they were silently ignored when a debugger was attached. The assert message will print to the debugger output (if attached) or OutputDebugString/syslog. - If the cDAC implementation of an API errors, it does not fall back to calling the legacy DAC. I think this is reasonable given that we plan to put the ability to choose cDAC vs legacy DAC at a higher level. If cDAC implementation fails, it should fail and not try to hide it. - `ClrDataAccess` lifetime is handled by cDAC (when enabled), so actual release is dependent on finalization of the COM object. I ran the SOS tests in diagnostics repo against this change locally both with and without the cDAC enabled.

Attributes are already marked from MarkType, called by MarkEntireType. The removed marking logic was using the assembly as the warning message origin, making these warnings hard to suppress (in addition to being redundant with the warnings at the type level).

Avoid cloning large loops. We compute loop size by counting tree nodes of all statements of all blocks in the loop. If this is over a threshold, we inhibit cloning. Threshold value was chosen based on distribution of unrestricted cloned loop sizes in the benchmark run_pgo collection.

When passing a struct by value on x86, we copy its value to the stack. Sometimes this is done one field at a time, if the struct has been promoted. If there is padding between the fields (to create appropriate field alignment), then that padding needs to be zeroed. The bug is a case where there is padding between an earlier `double` field and a later, larger, SIMD field. We push 4-byte zeros but the code thinks it is pushing 8-byte zeros. The fix is simply to correctly calculate the number of zeros to push. Fixes #106140

This is added as the last parameter by the Swift compiler, so to support instance calls taking parameters this needs to come last.

CSE cannot tolerate morph removing any defs, which many of morphs transformations can do. We have been slowly infecting morph with more and more checks to avoid this, but in reality CSE just should not reinvoke morph -- the benefits of doing this are minimal.

Newer versions of Clang warn when you are doing enum comparisons of different enum types.

Remove a stray end-of-line space

The TLS helper expansion would produce `ADD(long, int)` trees like ``` ▌ STORE_LCL_VAR long V01 rat0 └──▌ ADD long ├──▌ ADD long │ ├──▌ LCL_VAR long V02 rat1 │ └──▌ CNS_INT int 72 $41 └──▌ CNS_INT long 192 ``` which is not legal IR. Fix that by inserting a cast. Also do some more aggressive folding to get rid of these casts in the normal cases, and to fold some constant arithmeticf in other cases.

…(#108873) It should be _extremely_ rare to need to disable a test during SuperPMI collection. However, one case was found, so introduce the ability to do so. Use `<SuperPmiCollectIncompatible>true</SuperPmiCollectIncompatible>` in a test project file. (which also requires `<RequiresProcessIsolation>true</RequiresProcessIsolation>`) Fixes #108215

This change is some preparatory refactoring for the randomized allocation sampling feature. We need to add more state onto allocation context but we don't want to do a breaking change of the GC interface. The new state only needs to be visible to the EE but we want it physically near the existing alloc context state for good cache locality. To accomplish this we created a new ee_alloc_context struct which contains an instance of gc_alloc_context within it. The new ee_alloc_context.combined_limit field should be used by fast allocation helpers to determine when to go down the slow path. Most of the time combined_limit has the same value as alloc_limit, but periodically we need to emit an allocation sampling event on an object that is somewhere in the middle of an AC. Using combined_limit rather than alloc_limit as the slow path trigger allows us to keep all the sampling event logic in the slow path. PR feedback Co-authored-by: Jan Kotas <[email protected]>

- Replace them with using the normal monitor helpers - Change CORINFO_HELP_GETSYNCFROMCLASSHANDLE to return an `object` instead of the underlying lock object, implementation of the JIT helper can be shared with other `TypeHandle` to `RuntimeType` scenarios - This will likely improve the performance of synchronized methods, but that is beside the point, since this feature is so rarely used
