* Fix Crossgen2 bug #61104 and add regression test (#63956)

The issue tracks the runtime regression failure where
Crossgen2-compiled app is unable to locate a type with non-ASCII
characters in its name. The failure was caused by the fact that
Crossgen2 was incorrectly zero-extending the individual UTF8 characters
when calculating the hash whereas runtime is sign-extending them.

Thanks

* Fix invalid threading of nodes in rationalization (#64012)

The code in question assumes that the ASG will be
reversed and thus threads "simdTree" before "location"
in the linear order. That dependency, while valid,
because "gtSetEvalOrder" will always reverse ASGs
with locals on the LHS, is unnecessary and incorrect
from the IR validity point of view.

Fix this by using "InsertAfter" instead of manual
node threading.

* Fix issues with verify_regions, clear_batch_mark_array_bits. (#63798)

Details:
- we cannot verify the tail of the region list from background GC, as it may be updated by threads allocating.
- fix case in clear_batch_mark_array_bits where end is equal to the very end of a segment and we write into uncommitted memory in the mark_array.
-  bgc_clear_batch_mark_array_bits did some checks and then called clear_batch_mark_array_bits which repeated the exact same checks. Renamed clear_batch_mark_array_bits to bgc_batch_mark_array_bits and removed the old copy, removed the declaration for clear_batch_mark_array_bits.

* Fix exception propagation over HW exception frame on macOS arm64 (#63596)

* Fix exception propagation over HW exception frame on macOS arm64

There is a problem unwinding over the PAL_DispatchExceptionWrapper
to the actual hardware exception location. The unwinder is unable
to get distinct LR and PC in that frame and sets both of them to
the same value. This is caused by the fact that the
PAL_DispatchExceptionWrapper is just an injected fake frame and
there was no real call. Calls always return with LR and PC set
to the same value.

The fix unifies the hardware exception frame unwinding with Linux
where we had problems unwinding over signal handler trampoline, so
PAL_VirtualUnwind skips the trampoline and now also the
PAL_DispatchExceptionWrapper frame by copying the context of
the exception as the unwound context.

* Reenable DllImportGenerator.Unit.Tests

* Add StringSyntax attribute to Regex.pattern field (#64063)

I missed adding this one in my initial audit.  It'll be exceedingly rare for a developer to manually write code that assigns a string to this protected field, but every source-generated regex does so, and thus any colorization VS provides will benefit looking at the source-generated code.

* Make ILLink validation steps in libs incrementally buildable (#64041)

* Make ILLink validation steps in libs incrementally buildable

Both the illink-oob and the illink-sharedframework targets don't define Inputs and Outputs which makes them run during no-op incremental builds. This change defines Inputs and Outputs based on what's used during the target's execution so that if the input assemblies or the illink assembly itself haven't changed, the step will be skipped.

Also renaming properties and items to make them more readable and consistent. As these target files are "extensions" of the src.proj file and aren't shared anywhere, they can be treated like logic inside a project file and hence prefixing properties and items with an underscore "_" isn't necessary.

only set in "optNarrowTree" for uses.

For "def nodes" that are actually uses (parameters), the VNs
will never match anyway.

* Handle embedded assignments in copy propagation

Previously, as the comments in copy propagation tell us, it
did not handle "intervening", or not-top-level definitions of
locals, instead opting to maintain a dedicated kill set of them.

This is obviously a CQ problem, but also a TP one, as it meant
there had to be a second pass over the statement's IR, where
the definitions would be pushed on the stack.

This change does away with that, instead pushing new definitions
as they are encountered in execution order, and simultaneously
propagating on uses. Notably, this means the code now needs to
look at the real definition nodes, i. e. ASGs, not the LHS locals,
as those are encountered first in canonical execution order, i. e.
for a tree like:

```
  ASG
    LCL_VAR V00 "def"
    ADD
      LCL_VAR V00
      LCL_VAR V00
```

Were we to use the "def" as the definition point, we would wrongly
push it as the definition on the stack, even as the assignments
itself hasn't happened yet at that point.

There are nice diffs with this change, all resulting from unblocked
propagations, and mostly coming from setup arguments under calls.

* Make ApiCompat.proj incrementally buildable (#64037)

* Make ApiCompat.proj incrementally buildable

In https://github.com/dotnet/runtime/pull/64000, I noticed that ApiCompat.proj never builds incrementally. Even though the RunApiCompat target has Inputs and Outputs, those aren't defined too late inside the target to have any effect. Moving them out and declare the generated response file as an output.

Also simplifying some msbuild logic and renaming some properties as underscore prefixes in project files don't make sense if the property isn't reserved in any way.

* Address-expose locals under complex local addresses in block morphing (#63100)

* Handle complex local addresses in block morphing

In block morphing, "addrSpill" is used when the destination or source
represent indirections of "complex" addresses. Unfortunately, some trees
in the form of "IND(ADDR(LCL))" fall into this category.

If such an "ADDR(LCL)" is used as an "addrSpill", the underlying local
*must* be marked as address-exposed. Block morphing was using a very
simplistic test for when that needs to happen, essentially only recognizing
"ADDR(LCL_VAR/FLD)". But it is possible to have a more complicated pattern
as "PrepareDst/Src" uses "IsLocalAddrExpr" to recognize indirect stores
to locals.

Currently it appears impossible to get a mismatch here as morph transforms
"IND(ADD(ADDR(LCL_VAR), OFFSET))" into "LCL_FLD" (including for TYP_STRUCT
indirections), but this is a very fragile invariant. Transforming TYP_STRUCT
GT_FIELDs into GT_OBJs instead of GT_INDs breaks it, for example.

Fix this by address-exposing the local obtained via "IsLocalAddrExpr".

This is mostly motivated by NativeAOT subset builds where SPMI contributes to 10% of the native build time (nativeaot CorecLR subset builds pretty quickly compared to full CoreCLR).

* Implement hash and HMAC stream one shots 

This implements hashing and HMAC statics for streams. Additionally,
"LiteHmac" and "LiteHash" were introduced. The existing HMAC and hash
provider functionality do some bookkeeping we don't need for resetting.
Since we do not need to use these hash handles after the digest has
been finalized, resetting is unnecessary work. For HMAC, that also means
keeping a copy of the key around for some implementations which we don't
need to do.

The LiteHash and LiteHmac types are implemented as structs with a common
interface. To avoid boxing, generics are used and constrained to the interface
where possible.

The Browser implementation just defers to the existing HashDispenser rather
than do anything novel.

The HashProviderCng is somewhat specialized in its ability to reset. It did
up-front check to determine if the platform supported reusable hash providers,
and further had a single implementation for HMAC and Digests. The current
Lite hash design requires that they remain separate types.

* Tune FP CSEs live across a call better (#63903)

The problem was that the comparison of a weighted refcount,
which usually has the order of hundreds or tens, with a small
digit like "4" was too weak and missed some cases where we
were still trying to CSE cheaps floats across calls and ending
up with lots of stack shuffling.

Fix this by using different tuning parameters, namely the costs
estimated for the uses and defs (increase them to account for
the spills and reloads).

* Fix remote unwind (#64220)

The _OOP_find_proc_info was setting only a couple of members of the
unw_dyn_info_t instance on stack. So the remaining ones had random
values. The load_offset was a recently added member to the struct.
When we have updated libunwind, this change came in. The load_offset was
random and that has broken unwindign as this offset is subtracted from
the IP when looking up unwind info.

The fix clears the whole struct. I have verified that the issue we had no
longer happens with the fix.

* Android remove backward timezones (#64028)

Fixes #63693

It was discovered that Android produces duplicate TimeZone DisplayNames among all timezone IDs in GetSystemTimeZones. These duplicate DisplayNames occur across TimeZone IDs that are aliases, where all except one are backward timezone IDs.

If a name is changed, put its old spelling in the 'backward' file

From the Android TimeZone data file tzdata, it isn't obvious which TimeZone IDs are backward (I find it strange that they're included in the first place), however we discovered that on some versions of Android, there is an adjacent file tzlookup.xml that can aid us in determining which TimeZone IDs are "current" (not backward).

This PR aims to utilize tzlookup.xml when it exists and post-filter's the Populated TimeZone IDs in the AndroidTzData instance by removing IDs and their associated information (byteoffset and length) from the AndroidTzData instance if it is not found in tzlookup.xml. This is using the assumption that all non-backward TimeZone IDs make it to the tzlookup.xml file.

This PR also adds a new TimeZoneInfo Test to check whether or not there are duplicate DisplayNames in GetSystemTimeZones

* Refactor FileStatus.Unix. (#62721)

* Refactor FileStatus.Unix.

- Moves InitiallyDirectory out of FileStatus into FileSystemInfo.
In FileSystemInfo it can be a readonly field making its usage clearer.
And FileStatus can then directly be used to implement some FileSystem methods
without allocating an intermediate FileInfo/DirectoryInfo.

- Treat not exists/exist as initialized states to avoid wrongly assuming

not exist.

* Fixes bad log method generation in certain cases. (#64311)

In certain cases when developer by mistake places ILogger, Exception, or LogLevel in the message template,  the code generator will produce the expected warning and makes sure the code will indeed compile and run correctly.

Prior to this fix, the code generator would fail to compile with when either of ILogger, Exception or LogLevel were placed in message template incorrectly.

* Support {Last}IndexOfAny with sets after {lazy} loops (#64254)

When emitting backtracking loops, the loop consumes as much and then backtracks through the consumed input.  Rather than doing this one character by one character, we previously added use of LastIndexOf to search for the next place the literal after the loop matches.  We can also augment that to use IndexOfAny to search for a small set that comes after a loop instead of a literal.

Similarly when emitting backtracking lazy loops, rather than consuming one character and trying the rest of the expression and then consuming another character and trying the rest of the expression, we previously added an optimization to use IndexOf{Any} to find the next possible location of a match based on the literal that comes after the lazy loop.  And we can similarly augment that to support a small set after the lazy loop.

This is particularly helpful for IgnoreCase, as we're on a path to replacing literals with sets that contain all equivalent casings of that character.

* Fix race conditions in SystemEvents shutdown logic (#62773)

* Fix race conditions in SystemEvents shutdown logic

When the application is terminated through Restart Manager the event broadcasting window will get the `WM_CLOSE` message. The message gets handled by passing it to `DefWndProc` which calls `DestroyWindow` on the window itself thus making the window handle invalid. The `Shutdown` method expects the window handle to be valid to post `WM_QUIT` message to terminate the thread running the message loop but that's no longer possible under these conditions.

Additionally there's second race condition with the `s_eventThreadTerminated` event that is created during shutdown and set conditionally. A race condition between the threads could cause it to be created when the window message thread is already shutting down and thus it would never be set. Waiting for it in the `Shutdown` method would be cause a deadlock. This thread is also completely unnecessary since a `Join` is performed on the thread itself.

The fix has several changes that act together:
- `s_eventThreadTerminated` event is removed completely in favor of only relying on `Thread.Join`
- `WM_DESTROY` message is detected (which happens as a result of WM_CLOSE calling `DefWndProc` which in turn calls `DestroyWindow`) and handled by shutting down the message loop thread
- The message loop itself is rewritten to use standard `GetMessageW` loop. The reasoning on why it was not used seems not to be valid anymore since AppDomain shutdowns are performed differently

* Add unit test.

* Add braces

* Add marshaller for TypeLoad failure cases (#64317)

This is marshaller used when there incorrect configuration of marshaller applied to fields mostly

* Add additional loop table asserts (#64126)

1. Assert that top-level loops are basic block disjoint
2. Assert LPFLG_ITER related flags are legal

In addition:
1. Create a `optClearLoopIterInfo` phase to clear various bits in the loop
table that are known to no longer be valid, to prevent bad asserts or JitDump
output on their values.
2. Move the EndPhase call in Phase::PostPhase happens early, not late.
This causes any subsequent asserts due to post-phase checking to be
marked with the correct phase, in cases where there was a nested phase
executed (such as liveness re-computation).
3. Convert PHASE_INSERT_GC_POLLS to use EndPhase checking
4. Convert fgDetermineFirstCodeBlock to return a PhaseStatus
5. Some minor cleanup in optUpdateLoopsBeforeRemoveBlock()
(this was extracted from some bigger changes)

* Fix several bugs in NullabilityInfoContext.

* Reverse ASG(CLS_VAR, ...) (#63957)

This helps with register allocation. Consider:
```
***** BB01
STMT00001 ( 0x000[E-] ... ??? )
N003 ( 18, 10) [000003] -ACXG-------              *  ASG       ref    $c0
N001 (  3,  4) [000002] ----G--N----              +--*  CLS_VAR   ref    Hnd=0x8fec230 Fseq[hackishFieldName]
N002 ( 14,  5) [000000] --CXG-------              \--*  CALL      ref    CscBench.GetMscorlibPathCore $c0
```
The rationalizer will rewrite it to what is effectively:
```
***** BB01
STMT00001 ( 0x000[E-] ... ??? )
N004 ( 18, 12) [000003] -ACXG---R---              *  ASG       ref
N003 (  3,  6) [000002] n---G--N----              +--*  IND       ref
N002 (  1,  4) [000006] H-----------              |  \--*  CLS_VAR_ADDR byref  Hnd=0x8fec230
N001 ( 14,  5) [000000] --CXG-------              \--*  CALL      ref    CscBench.GetMscorlibPathCore
```
And the final LIR will look like:
```
               [000006] ------------                 IL_OFFSET void   INLRT @ 0x000[E-]
N001 (  3,  4) [000002] ----G--N----         t2 =    CLS_VAR_ADDR byref  Hnd=0x8fec230
N002 ( 14,  5) [000000] --CXG-------         t0 =    CALL      ref    CscBench.GetMscorlibPathCore $c0
                                                  /--*  t2     byref
                                                  +--*  t0     ref
N003 ( 18, 10) [000003] -A-XG-------              *  STOREIND  ref
               [000007] ------------                 IL_OFFSET void   INLRT @ 0x00A[E-]
N001 (  0,  0) [000004] ------------                 RETURN    void   $180
```
Since this store must use a barrier, `CLS_VAR_ADDR` won't be contained and will have to be evaludated
separately. Because its value is live across a call, it'll get spilled and reloaded. Reversing the ASG
fixes the problem:
```
------------ BB01 [000..00B) (return), preds={} succs={}
               [000006] ------------                 IL_OFFSET void   INLRT @ 0x000[E-]
N001 ( 14,  5) [000000] --CXG-------         t0 =    CALL      ref    CscBench.GetMscorlibPathCore $c0
N002 (  3,  4) [000002] ----G--N----         t2 =    CLS_VAR_ADDR byref  Hnd=0x8fec230
                                                  /--*  t2     byref
                                                  +--*  t0     ref
N003 ( 18, 10) [000003] -A-XG-------              *  STOREIND  ref
               [000007] ------------                 IL_OFFSET void   INLRT @ 0x00A[E-]
N001 (  0,  0) [000004] ------------                 RETURN    void   $180
```

* [wasm] Build WasmAppHost with UseAppHost=false (#70606)

* [wasm] Build WasmAppHost with UseAppHost=false

- WasmAppHost is included in the WebAssembly.Sdk pack, and doesn't have a
platform specific package.
- Since, this is being built for x64, the build defaults to using the
app host, which means that we get a single binary file that can be run
directly.
    - But this also means that the binary included in the
    WebAssembly.Sdk platform-agnostic package will target the platform
    where it was built.

- Instead, build with UseAppHost=false, and update the wasm host to use
the managed assembly instead.

And update the RunCommand to use `dotnet exec WasmAppHost.dll`.

* JIT: Optimize expansion of indir cell addresses for CFG (#70491)

On ARM64 it is expensive to materialize the address of an indirection
cell since that requires multiple instructions. This is particular a
problem when CFG is enabled where validation + call uses the indir cell
twice. This changes the CFG logic to create a local in this case.

We also were forcing the indir cell argument node into the register.
This is not ideal for this particular case, so remove this logic and let
LSRA deal with it. ARM still needs this logic.

Fix #65076

* Handle mis-sized structs in XARCH `PUTARG_STK` codegen (#68611)

* Handle "mis-sized" structs in XARCH PUTARG_STK codegen

Previously, for structs which were not a multiple of TARGET_POINTER_SIZE
in size:

1) On x86, we copied them to a local in morph. This was a small CQ issue.
2) On Unix x64, we didn't handle them at all and could read out of bounds
   in "genStructPutArgUnroll".

This change fixes both issues by properly detecting cases where we need to
be careful and updating codegen to use correct load sizes.

* [wasm] WBT: Fix a failing satellite assembly test

The test fails because it is trying to find the string `got: こんにちは`

same.

Instead of that, we can move the check to be in the app itself, thus
removing the need for any of this.

* Avoid throwing Win32Exception from HTTP authentication (#70474)

* Avoid throwing Win32Exception from HTTP authentication

When server sends malformed NTLM challenge the NT authentication processing
would throw an unexpected Win32Exception from HttpClientHandler.Send[Async]
calls. This aligns the behavior to WinHTTP handler where the Unauthorized
reply with challenge token is returned back to the client.

Similarly, failure to validate the last MIC token in Negotiate scheme could
result in Win32Exception. Handle it by throwing HttpRequestException instead.

* Use IndexOf in WebUtility (#70700)

The IndexOfHtmlDecodingChars method was iterating character by character looking for either a `&` or a surrogate, but then the slow path if one of those is found doesn't special-case surrogates.  So, we can just collapse this to a vectorized `IndexOf('&')`, which makes the fast path of detecting whether there's anything to decode much faster if there's any meaningful amount of input prior to a `&`. (I experimented with also using `IndexOf('&')` in the main routine, but it made cases with lots of entities slower, and so I'm not including that here.)

According to my comparative perf measurements composite framework
spends about 5M more instructions in the method

coreclr.dll!CMiniMdTemplate<CMiniMd>::SearchTableForMultipleRows(CMiniColDef sColumn)

I tracked this down to the R2R table AttributePresence which is
used to speed up attribute queries against the ECMA metadata model.
In composite mode we were putting the table in the image header,
not component header, and so the runtime was unable to locate it.
This change fixes generation of the table in Crossgen2; I have
verified that with this change I no longer see the 5M outlier.

Thanks

* Support `PUTARG_STK(STRUCT LCL_VAR/LCL_FLD)` on ARM/64 (#70256)

* Separate out LowerPutArgStk

Call it from "LowerArg" instead of "ContainCheckCallOperands",
as it does more than just containment analysis.

* Support "PUTARG_STK(STRUCT LCL_VAR/LCL_FLD)" on ARM/64

To test this, transform "OBJ(LCL_VAR|FLD_ADDR)" to "LCL_FLD" on lowering.

This additionally simplified the codegen code as it doesn't have to support
two representations of the same thing.

* Allow `TYP_STRUCT` `LCL_FLD` on the RHS of block copies (#70633)

* Delete the unused "GTF_USE_FLAGS"

It used to indicate that a branch operation didn't
need to materialize its operand and could just "use
flags" instead, but that purpose has long been lost
now that we have explicit SETCC nodes in lowering.

* Make GTF_DONT_EXTEND a shared flag

So that it can be used for "LCL_FLD" as well as "GT_IND".

No diffs.

* Enable TYP_STRUCT on the RHS

* fgMorphBlockOperand

* Tweak TYP_STRUCT LCL_FLD costs

Model it as two load, like OBJ.

Note we could be more precise here, by using the
register type of the layout. For now, we defer.

* Block CSE

Preserve previous behavior to avoid diffs.

* Enable redirection on arm64 (#70769)

* Handle HW exceptions on Windows without redirection (#70428)

This change modifies the way hardware exceptions are propagated from the

vectored exception handler with instruction pointer in the context set
to an asm helper. That redirected the thread to that helper and we have
raised an exception from its call chain.
While working on CET support, it was found that propagating exceptions
from the vectored exception handler directly works just fine. So this
change makes it work that way for all Windows targets.

* Enable ThreadAbort with CET enabled via the QueueUserAPC2 (#70803)

This change makes ThreadAbort work when CET is enabled. Instead of
thread redirection, it uses the new user mode APC mechanism to get a
thread to a handler and then throws the ThreadAbortException from there
if the thread was interrupted at a safe location.

I have verified it works using mdbg tests and also by manual testing in
the Visual Studio 2022 using a test app that creates an instance of
classes with properties containing infinite loop, wait on a lock, wait
on a handle, infinite loop inside of a lock and infinite loop in
finally.
For the testing, I've enabled this separately from the CET so that the
missing support for CET in the debugger code doesn't cause troubles.

So we could enable this without CET enabled too, but I'd prefer doing
that separately.

the BLOCKING_SUSPEND_REQUESTED state is treated as suspend in full
coop mode (the thread keeps running, but by definition it's not
allowed to access managed resources and it will self-suspend if it
tries to enter GC Unsafe mode by calling a runtime API or managed
code).
It is bad in hybrid suspend mode (the thread should be preemptively
suspended, but we timed out before the signal handler had a chance to
run).

The corresponding suspension logic in the code is:

* JIT: break loop canonicalization into two stages (#70809)

For a given loop, we need to separate out the true backedge, any

Otherwise, we may violate assumptions that the loop entry dominates
all blocks in the loop and that all backedges that reach top come
from within the loop.

This seems simplest to do with two rounds of canonicalization, one
that moves the non-loop edges, and another that moves the true backedge.

* [wasm] Add support for per-project customization of helix work items (#70461)

* [wasm] Add support for per-project customization of helix work items

Currently, for sending tests to helix:
1. the project binaries are zipped, as part of the project build
2. then separate helix targets files build that adds helix items for
   those zip files.
    - for wasm, we test with multiple 'scenarios' - like v8, browser, and
    nodejs.
    - so, 3 helix work items are submitted per zip file

- If a test project needs to have any customizations, for example, for
  testing crypto with a managed implementation, and subtlecrypto, which
  would require:
  - passing different arguments to xharness, in case of managed, and
    subtlecrypto
  - and this should be done only for the browser case
  - Currently, this would need this would need to be done in
  `sendtohelix-wasm.targets` special casing for the test project, and
  scenario.

- We add support for importing `$(ProjectName).helix.targets`, and
  calling a special target in that to add helix items, as needed.

- This targets file can be set in the test project like:
```xml
<HelixTargetsFile Condition="'$(TargetOS)' == 'Browser'">wasm.helix.targets</HelixTargetsFile>
```
  - it will get deployed next to the zip file, and picked up automatically

```xml
<Project>
  <PropertyGroup>
    <_CryptoProjectName>System.Security.Cryptography.Tests</_CryptoProjectName>
    <System_Security_Cryptography_Tests_TargetName Condition="'$(Scenario))' == 'WasmTestOnBrowser'">System_Security_Cryptography_Tests_Targ
et</System_Security_Cryptography_Tests_TargetName>
  </PropertyGroup>

  <Target Name="System_Security_Cryptography_Tests_Target">
    <ItemGroup>
      <HelixWorkItem Include="$(Scenario)-managed-$(_CryptoProjectName)">
        <PayloadArchive>$(TestArchiveTestsDir)$(_CryptoProjectName).zip</PayloadArchive>
        <Command>$(HelixCommand)</Command>
        <Timeout>$(_workItemTimeout)</Timeout>
      </HelixWorkItem>

      <HelixWorkItem Include="$(Scenario)-subtlecrypto-System.Security.Cryptography.Tests">
        <PayloadArchive>$(TestArchiveTestsDir)$(_CryptoProjectName).zip</PayloadArchive>
        <Command>$(HelixCommand)</Command>
        <Timeout>$(_workItemTimeout)</Timeout>

        <PreCommands Condition="'$(OS)' == 'Windows_NT'">set &quot;WasmXHarnessArgs=--web-server-use-cors&quot;</PreCommands>
        <PreCommands Condition="'$(OS)' != 'Windows_NT'">export &quot;WasmXHarnessArgs=--web-server-use-cors&quot;</PreCommands>
      </HelixWorkItem>
    </ItemGroup>
  </Target>
```

- The targets file *must* have these:
    - a property named like `System_Security_Cryptography_Tests_TargetName`, for a
      test project named `System.Security.Cryptography.Tests`
    - if this property is not set, then the default behavior of adding
      work items will run
    - The target should add any items it needs to to `@(HelixWorkItem)`.
      - Examples of adding these can be seen in `sendtohelix*` project files

- Remember that all these properties, and targets get imported into the
  msbuild *global* namespace, so make sure to use unique names to avoid
  conflicts with other test projects.

Future work: this commit only enables it for wasm/library tests, but it should
be easy to extract it out, but needs some testing.

This reverts commit 7ef99e81f82200189dd3f61eeaf00d6ca4ced6d4.

* Update src/libraries/System.Security.Cryptography/tests/wasm.helix.targets
Co-authored-by: NEric Erhardt <eric.erhardt@microsoft.com>

* Address review feedback

* remove debug spew

* Change the way helix extension targets are discovered.

The new approach:

To run a custom project specific target for adding/editing @(HelixWorkItem):

- In the project add:
    `<HelixTargetsFile Condition="'$(TargetOS)' == 'Browser'">wasm.helix.targets</HelixTargetsFile>`

    - This file gets copied next to the test archive as $(MSBuildProjectName).helix.targets

- In this `wasm.helix.targets` file, add to $(HelixExtensionTargets) to run your custom target

```xml
  <PropertyGroup Condition="'$(IsRunningLibraryTests)' == 'true' and '$(Scenario)' == 'WasmTestOnBrowser'">
    <HelixExtensionTargets>$(HelixExtensionTargets);_AddHelixCrypoItems</HelixExtensionTargets>
```

- The extension target will be called after the default items are added
  to `@(HelixWorkItem)`.
- Useful properties to condition on: $(Scenario), $(IsRunningLibraryTests)
- And add to, change, or remove from @(HelixWorkItem)

Example:
```xml
  <Target Name="_AddHelixCrypoItems">
    <ItemGroup>
      <!-- remove the existing item -->
      <HelixWorkItem Remove="@(HelixWorkItem)" Condition="'%(OriginalFileName)' == '$(_CryptoProjectName)'" />

        <!-- add two new ones - managed, and subtylecrypto -->
      <HelixWorkItem Include="$(WorkItemPrefix)managed-$(_CryptoProjectName)">
        <PayloadArchive>$(TestArchiveTestsDir)$(_CryptoProjectName).zip</PayloadArchive>
        <Command>$(HelixCommand)</Command>
        <Timeout>$(_workItemTimeout)</Timeout>
        <OriginalFileName>$(_CryptoProjectName)</OriginalFileName>
      </HelixWorkItem>

      <HelixWorkItem Include="$(WorkItemPrefix)subtlecrypto-$(_CryptoProjectName)">
        <PayloadArchive>$(TestArchiveTestsDir)$(_CryptoProjectName).zip</PayloadArchive>
        <Command>$(HelixCommand)</Command>
        <Timeout>$(_workItemTimeout)</Timeout>
        <OriginalFileName>$(_CryptoProjectName)</OriginalFileName>

        <PreCommands Condition="'$(OS)' == 'Windows_NT'">set &quot;WasmXHarnessArgs=%WasmXHarnessArgs% --web-server-use-cop&quot;</PreCommands>
        <PreCommands Condition="'$(OS)' != 'Windows_NT'">export &quot;WasmXHarnessArgs=$WasmXHarnessArgs --web-server-use-cop&quot;</PreCommands>
      </HelixWorkItem>

      <_CryptoHelixItem Include="@(HelixWorkItem)"
                        Condition="$([System.String]::new('%(HelixWorkItem.Identity)').EndsWith('-$(_CryptoProjectName)'))" />
    </ItemGroup>

    <Error Text="Something went wrong. Expected to have only two work items for $(_CryptoProjectName). But got @(_CryptoHelixItem)"
           Condition="@(_CryptoHelixItem->Count()) != 2" />
  </Target>
```

* Add support for delegate GDV and method-based vtable GDV (#68703)

Add support for instrumenting delegate calls and vtable calls into method handle histograms. Use these histograms to do GDV for delegate calls and also support method-based GDV for vtable calls.

For instrumentation we now support class probes at interface call sites, method probes at delegate call sites and both class probes and method probes at vtable call sites. For vtable calls, when turned on, instrumentation produces both histograms as PGO data so that the JIT can later make the choice about what is the best form of guard to use at that site.

For guarding, there are some things to take into account. Delegate calls currently (practically) always point to precode, so this PR is just guarding on getFunctionFixedEntryPoint which returns the precode address, and this is generally quite cheap (same cost as class-based GDV). That's the case for delegates pointing to instance methods anyway, this PR does not support static methods yet -- those will be more expensive.

For vtable calls the runtime will backpatch the slots when tiering, so the JIT guards the address retrieved from the vtable against an indirection of the slot, which is slightly more expensive than a class-based guard.

Currently the instrumentation is enabled conditionally with COMPlus_JitDelegateProfiling=1 (for delegates) and COMPlus_JitVTableProfiling=1 (for vtable calls). Currently delegate profiling is turned on by default while vtable profiling is off by default.

* [wasm] Wasm.Build.Tests: Disable strict version checks for emcc

Due to the way we have to update `dotnet/emsdk`, and get the update PRs
in `runtime`, the emsdk version can be mismatched. For example, if
`dotnet/emsdk` has already updated to `3.1.12`, but `dotnet/runtime` is
still on `3.1.7`. This is an expected scenario while working on updating
to a newer emscripten.

The version mismatch will still show up, but as a warning now.

* [wasm] Wasm.Build.Tests: Update Skiasharp reference

The skiasharp dependent tests fail with:
`error : undefined symbol: _ZNKSt3__220__vector_base_commonILb1EE20__throw_length_errorEv`.

Update the reference to the latest package which added a binary compiled
for `3.1.7`.

* [wasm] Workaround a test failure in WBT

Currently, there is a mismatch between emsdk versions with the workload
emscripten packs using `3.1.12`, and the runtime being built with
`3.1.7`. And that is causing
`Wasm.Build.Tests.NativeLibraryTests.ProjectUsingSkiaSharp` to fail with:

```

This commit adds a temporary workaround to ignore the undefined symbols
for this specific test. And this should be removed when runtime is
updated to `3.1.12` .

* superpmi.py: Add `-jitoption` for asmdiffs (#70939)

The new `-jitoption` option passes the argument options to both baseline and diff
compilers. This is a convenience option: there already is `-base_jit_option` and
`-diff_jit_option` to specify passing options to either baseline or diff.

The name of the option is the same as that used for `replay`.

would be incorrect if one and two SP adjustment full frame aligned sizes are different (e.g.,
if two SP adjustment required two alignment slots and one SP adjustment thus required none).

* Add support for cross module inlining and cross module generic compilation to Crossgen2 (#68919)

* Add support for cross module inlining and cross module generic compilation to Crossgen2
- Refactor Module into ModuleBase and Module
  - The goal is to have allow a subset version of Module which can only hold refs, this is to be used by the manifest module in an R2R image to allow for version resilient cross module references.
  - Update handling of ModuleBase so that its used everywhere that tokens are parsed from R2R
  - Remove ENCODE_MODULE_ID_FOR_STATICS and ENCODE_ACTIVE_DEPENDENCY
    - These were only used for NGEN, and conflict with easy impelmentation for the ModuleBase concept
  - Remove locking in ENCODE_STRING_HANDLE processing, and tweak comments. Comments applied to the removed ngen based code, and the lock was only necessary for the old ngen thing.
  - Adjust ComputeLoaderModuleWorker for locating loader module
    - Follow comment more accurately, to avoid putting every generic into its definition module. This will make R2R function lookup able to find compiled instantiations in some cases. This may be what we want long term, it may not.
  - Remove MemberRefToDesc map and replace with LookupMap like the other token types. We no longer make use of the hot table, so this is more efficient
    - Also reduces complexity of implementation of ModuleBase

- Build fixup to describe a single method as a standalone blob of data
  - There are parallel implementations in Crossgen2 and in the runtime
  - They produce binary identical output
  - Basic R2RDump support for new fixup

- Adjust module indices used within the R2R format to support a module index which refers to the R2R manifest metadata. This requires bumping the R2R version to 6.2
  - Add a module index between the set of assembly refs in the index 0 module and the set of assembly refs in the R2R manifest metadata

- Adjust compilation dependency rules to include a few critical AsyncStateMachineBox methods

- Remove PEImage handling of native metadata which was duplicative

- Do not enable any more devirtualization than was already in use, even in the cross module compilation scenario. In particular, do not enable devirtualization of methods where the decl method isn't within the version bubble, even if the decl method could be represented with a cross-module reference token. (This could be fixed, but is out of scope for this initial investigation)

Make the compilation deterministic in this new model, even though we are generating new tokens on demand
  - Implement this by detecting when we need new tokens during a compile, and recompiling with new tokens when necessary
  - This may result in compiling the same code as much as twice

Compile the right set of methods with cross module inlining enabled
- Add support for compiling the called virtual methods on generic types
  - This catches the List<T> and Dictionary<TKey,TValue> scenarios

- Add command line switches to enable/disable the new behavior
  - By default the new behavior is not enabled

* Override ReadAsync and WriteAsync methods on ConsoleStream.

The base Stream class implements these overloads by renting a buffer,
creating a ReadWriteTask, and copying data as necessary.

Instead, ConsoleStreams can just override these Async methods and synchronously
call the underlying OS API.

Add tests to verify that input and output console streams behave correctly.

* Fix stdin tests to only run on supported platforms.

* downgrade proposal for HttpClient

* HttpClient to handle ws over h2

* ClientWebSocket to handle ws over h2

* InstallWorkloadFromArtifact: Support multiple workloads

* [wasm] Move the templates pack to a new workload - wasm-experimental

Reuse lists (now hashtables) of outstanding reads in "CheckLclVarSemanticsHelper".

In recent Android versions the data returned by getifaddrs is invalid and doesn't allow us to implement System.Net.NetworkInformation.GetAllNetworkInterfaces(). It's possible to reimplement getifaddrs using Netlink and there's already an existing implementation in Xamarin.Android.

Fixes xamarin/xamarin-android#6973
Ref #62780
Ref #51303

* Removed (uint) cast workaround in CoreLib, annotated missing places with TODOs

* Fixed the bug I introduced in TimeSpanParse.TimeSpanTokenizer

* Use uint-cast on both sided for clarity

Cf. https://github.com/dotnet/runtime/pull/67448#discussion_r841082992

* Use uint-division in BitHelper as the JIT can produce more efficient code

Cf. https://github.com/dotnet/runtime/pull/67448#discussion_r841239729

* Don't have struct local in ValueStringBuilder due to hitting JIT optimization limits

Cf. https://github.com/dotnet/runtime/pull/67448#discussion_r841129465

* BitHelper with uint division and without Math.DivRem for even better codegen

AggressiveInlining isn't needed anymore, also the JIT recognizes the _span field, so no local Span is needed here.

* BitHelper needs local Span due to regression in jit-diff otherwise

* Added Debug.Asserts to BitHelper's method that take bitPosition

* BitHelper: comment for workaround to tracking issue

* Add logic for selecting the right version of pgort140

* Address PR feedback

* Add logic for x86 pgort

* Remove dead code

Fix #71987

* Add ConditionalFact to 'unelevated' tests to ensure they are not executed in elevated mode.

* Fix test that was incorrectly executed async

IsNETCoreAppAnalyzer is automatically calculated based on the NetCoreAppLibrary.props file. Setting this in the project file doesn't have any impact.

The problem is if there is a high-level framework which lists its dependencies as for example NETCore.App first and then ASPNET.App. When we reorder the frameworks during resolution we try to put the lowest level last, but the reorder doesn't work if there's a high-level framework which depends on middle one last - as the last resolved framework in that scenario will be the middle one (ASPNET.App) and it will end up last in the list.

The code assumes the last framework is the root (NETCore.App) and thus we look for hostpolicy there.

* Delete the custom gitignore file

The root gitignore file already contains most of these settings and should be preferred.

* Delete .gitignore

- mark JSImportGenerator C# only
- Viktor's feedback
- put back lost method GetCSOwnedObjectJSHandleRef

* Round 1

Actually failing build:
System.Diagnostics.Debug.Tests

Made fully passing:
System.Diagnostics.FileVersionInfo

* Round 2

All of these tests build just fine. Many of them also fully pass.

* Round 3

* Round 4

* Update tests.proj

* Hack around the WASM hacks

* Update tests.proj

* Update System.Diagnostics.FileVersionInfo.Tests.csproj

* Update tests.proj

The only difference between the Android and the "Other" case is the SymbolsSuffix .debug instead of .dbg which was added a long time ago in the old CoreCLR Android port:  https://github.com/dotnet/runtime/commit/239186ae975de5cf735d80540db6fe1907126a5b

We only ever used .dbg extension for the Android symbols (like Linux) in the Mono Android port.

* Improve Generics support in System.Text.Json.SourceGeneration

* Apply suggestions

* Apply suggestions 2

* unify first element check

* apply code styles

* [wasm] Disable tests failing on HighResourceAOT job

- Disabling `FunctionalTests/System.Text.RegularExpressions.Tests` this
  test for HighResourceAOT
- Also, ensure that the HighResourceAOT tests are run for regular
  library tests, and EAT.

Issue: https://github.com/dotnet/runtime/issues/71848

* Disable for EAT also

* [wasm] Disable some STJ.Serialization tests failing due to linker issues

This seems to be hit only with `EnableAggressiveTrimming=true`, and
`RunAOTCompilation=true`. All the traces are similar to:

```
