Disable nop padding in R2R images and remove jumpstamps from the runtime (dotnet/coreclr#26740)
Jumpstamps were used to version methods before we had the tiered compilation versioning mechanism. Jumpstamps had some negatives, that it was only supported on x86 and x64, that it required padding methods (bloated on disk IL code size), and that it required a runtime suspension to write the jumpstamps. By consolidating to one code versioning scheme we can delete a lot of code and support all architectures that tiered compilation does for rejit.

Reuse managed test components across all *nix flavors (dotnet/coreclr#26581)
Today CoreCLR pipelines build tests on the same OS flavors they are
supposed to run on. This is wasteful as we produce identical
managed test artifacts on OSX, Linux, Linux_musl and Linux_rhel6.
With this change, the pipeline construction analyzes the set of
OS / architecture combos to run tests on and picks the "best"
OS (or rather the OS that runs on the fastest lab HW) for build
of the managed test components.
Native test components are newly built as part of the product build
as these do need to be built separately for each targeting OS.
Product build zips them up and publishes them to Azure as an artifact
that gets subsequently downloaded and stitched together with
managed test components in the test run job.
Implementation-wise the change basically proceeds in two steps.
In platform-matrix.yml we first identify the exact set of OS / arch
combos to run. Using this information we subsequently identify
the OS to build managed components on for each combo; this information
is passed to test-job.yml which skips managed test build for those
OS-es that are expecting the managed components to be built on a
different OS.
Product build (build-job.yml) contains the additional logic to
build native test artifacts and publish the to Azure for perusal
by the test run job that downloads and unzips both managed and native
artifacts into the final test folder before publishing to Helix.

The GlobalMemoryStatusEx in PAL is returning number of free physical pages in

as buffers and caches that get released when there is a memory pressure and
thus they are effectively available too.
This change extracts the available memory on Linux from the /proc/meminfo

Fix managed test artifacts to be *nix flavor-agnostic (dotnet/coreclr#26817)
After I finally managed to make my infra change to reuse managed
test artifacts across various *nix flavors work on the CoreCLR-CI
Pri0 pipeline, I proceeded to testing the official build which
uncovered a single Pridotnet/coreclr#1 test violating the independence principle:
<pre>
Loader\AssemblyDependencyResolver\AssemblyDependencyResolverTests\AssemblyDependencyResolverTests.csproj
</pre>
This test project uses the clause
<pre>
<RequiresMockHostPolicy>true</RequiresMockHostPolicy>
</pre>
which makes the script CLRTest.MockHosting.targets emit an
OS-specific name of the mock hosting dynamic library to the
execution .sh script which then becomes non-portable between
Linux and OSX because they use different extensions for dynamic
libraries (so / dylib).
My proposed change fixes this by modifying the targets file to
emit just the library name without the extension and append
the appropriate per-OS extension in CoreRun.
Thanks

Skip the MethodRef optimization for ArrayMethod's (dotnet/coreclr#26850)
As Jan Vorlicek discovered during his investigation of the remaining

is due to the fact that array types are somewhat weird as they are
kind of "generic types in disguise".

New SuperIlc command "compile-framework" and some fixes (dotnet/coreclr#26804)
1) New command "compile-framework" does just what it says on the tin.
My thinking is that I'll use this option to build the CPAOT
framework during product build in the envisioned pipeline. I have
added hard-coded exclusions for assemblies that fail to build right
now - about half of them aren't interesting as framework assemblies
(e.g. R2RDump.dll), some other fail with IBC bugs and one other bug
I'm about to investigate.
2) Based on JanV's suggestion I have added a somewhat hacky logic
to exclude the "testhost" folder when building the entire Pridotnet/coreclr#1
test tree. I'm open to suggestions how to tackle this in a cleaner
manner, I have shared my thoughts on the subject in code comments
next to the problematic spots.

* Fix issue with locals overlapping out of scope GCFrame
More aggressive C/C++ optimizations done by VS2019 are breaking fragile
assumptions of the CoreCLR "manually managed code".
Unwinding of Frame chains accesses stack local variables after the stack
frame has been unwound, but it depends on their content to be left
intact. The new compiler is breaking this assumption by stack-packing a
different variable over it.
This change fixes the problem by adding a destructor to GCFrame that
pops the frame from the per-thread Frame list.
I also had to refactor two functions where the compiler was complaining
about mixing SEH and C++ EH in single function.
With these changes applied, there was still a problem that I've discovered
when running CoreCLR tests with GCStress 3. When the
ExceptionTracker::m_pInitialExplicitFrame was still pointing to a frame
that was already removed from the explicit Frame chain. When the
ExceptionTracker::HasFrameBeenUnwoundByAnyActiveException was walking
the frame chain starting at m_pInitialExplicitFrame to figure out if a given
frame was already unwound, it has walked to the destroyed GCFrame and
crashed.
To fix that, the chain from the initial explicit frame is updated so
that it stays valid (effectively, the destroyed GCFrame is removed from
it). It was also necessary to handle the case when the destroyed GCFrame
was the ExceptionTracker::m_pLimitFrame. The limit frame needs to be
updated to the next frame so that it can be reached on the chain from
the initial explicit frame.

Remove tailcall limitations on unix64 and arm64 (dotnet/coreclr#26255)
* Remove tailcall limitations on unix64 and arm64
Fast tailcalls have their arguments passed in the incoming argument area
of the caller. This can cause problems when a previous argument might
end up overwriting the stack slot for an incoming argument that is later
used. To resolve this problem, we have logic that detects and introduces
temps in this situation. This logic was originally written for Windows
x64 where it is simple to know what argument is being overwritten, since
every argument always takes up a single slot on the stack. I.e. we know
that outgoing argument 7 can only overwrite incoming argument 7.
On unix x64 and arm64 this assumption does not hold. We previously tried
to workaround this by limiting our fast tailcalls to simple situations
where this assumption held, but this caused many missed fast tailcall
opportunities (for example, when arguments requires two slots or more).
This change removes those limitations. Instead of finding the argument
overwritten using the argument index, it keeps track of which stack
slots are used by each incoming and outgoing argument, allowing us to
more robustly check if an outgoing argument will overwrite an incoming
argument that will be used later.
To do this, we need to set the stack offset during init of args so that
we can use this info to determine whether it is necessary to introduce
temps for fast tailcalls. For arm64 we now define
FEATURE_PUT_STRUCT_ARG_STK to have access to the number of slots in
PUTARG_STK needed for this transformation.
There are also some corner cases we must consider. Since arguments now
consume multiple stack slots we can no longer move them with a single
atomic move instruction. Thus it is possible for us to get into cases
where we need to move an argument that is larger than 8 bytes and where
the move overlaps. This is a problem because codegen cannot handle
partially overlapping struct copies. We see this on unix64 in the
following case (assuming all args are on the stack):
void callee(S16 a, S32 b) { ... }
void caller(S32 a) { callee(default, a); }
Here 'caller' will need to move 'a' 16 bytes ahead in the arg list, and
we thus need a temp because we cannot do this atomically. Fix this by
detecting the partially overlapping case and looking for uses of the arg
from the current PUTARG_STK node's operand (instead of only starting
after).
