Daco Harkes b52113314b [vm/ffi] Structs by value compiler frontend (part 2)
Split off https://dart-review.googlesource.com/c/sdk/+/140290 to make
that CL smaller.

This CL adds support for passing struct arguments in the native calling
convention calculation in
`runtime/vm/compiler/ffi/native_calling_convention.cc`.

The code in this CL is unit tested with expect files. The unit tests are
designed to cover the majority of corner cases in the ABIs without
resorting to very many unit tests.

TEST=runtime/vm/compiler/ffi/native_calling_convention_test.cc

The code in this CL has been end-to-end tested in the CL it is split off
from. And will be end-to-end tested when that CL also lands.

Tess Strickland 1c4c5ed895 [vm/compiler] Don't use runtime check stubs on TTS-enabled architectures
The type testing stub (TTS) assigned to top types always succeeds, and
types are assigned null-accepting TTSes if nullable. Thus, calling the
runtime check stubs relanded in 3b9b7796 is redundant for architectures
that use TTSes.

TEST=Existing tests via trybots on all architectures.

Tess Strickland 3b9b77964d Reland "[vm/compiler] Move AssertAssignables out of closure bodies."
This is a reland of 42c76fd910

Main issue was due to the parameter order of the invoke field dispatcher
not matching the argument order described by its saved arguments
descriptor. There's no reason for it not to, so now it does.

Also fixes some issues with stack trace tests that failed due to
increased deduplication of closures by forbidding deduplication for
those tests.

TEST=Run on trybots of all architectures as well as flutter engine
trybot, new test added for downstream issues seen after initial landing.

Tess Strickland 4f73b3374b [vm] Add type slot to SubtypeTestCache.
This CL extends SubtypeTestCache entries with an additional slot that
contains the type being checked, to allow for future uses where
different runtime types can flow through a single checkpoint. This
change is separated from those future uses to determine the impact of
these changes only.

Thus, most SubtypeTestCache checks require the type as an additional
argument, and now the destination type register in TypeTestABI is now
untouched in SubtypeTestCache checks. Since there are currently no plans
for a dynamic InstanceOf test, the one argument SubtypeTestCache is left
unchanged.

Until we add cases in later CLs where the type can differ at the same
AssertAssignable instruction, we could check the type last since it is
currently guaranteed to be the same each time. However, we instead check
it after the instance, which is when it should be checked once we have
AssertAssignable instructions with types only known at runtime.  This
avoids having to change it later, but also ensures the measured impact
of these changes can be compared to the impact of later changes.

In addition, this CL also unifies most of the code used by
GenerateInstanceOf (and also GenerateAssertAssignable via
GenerateInlineInstanceof on IA32). This is possible since register use
changes in the helper functions has eliminated the need to push the
instantiator and function type argument registers from TypeTestABI on
non-X64 architectures. By unifying these methods, we ensure that all
architectures appropriately set TypeTestABI::kDstTypeReg when necessary.

TEST=Existing tests on all architectures, change in object_test.cc.

Tess Strickland e7a2fbe692 [vm/compiler] Unify TTS implementations across architectures.
The only architecture-specific part of type testing stubs (TTS) is which
registers get saved/restored across SubtypeTestCache stub calls in the
slow TTS implementation, which is now a register mask constant in the
TypeTestABI struct.

This CL also:

* Creates a single definition of OperandSize in assembler_base.h. Moves
  OperandSize into the compiler namespace.  assembler_base.h. Renames
  constants common to all architectures to neutral names (e.g., kWord =>
  kFourBytes), since "word" has different meanings across architectures.

* Creates a new JumpDistance enum for kNearJump/kFarJump in
  AssemblerBase and replace existing bool uses with the constants.

* Adds JumpDistance arguments to some of the generalized Assembler
  methods so they aren't forced to use far jumps on IA32/X64. These
  added JumpDistance arguments are ignored on ARM architectures.

* Adds a new generalized Assembler::LoadIndexedPayload method for
  loading indexed objects out of post-header variable-length payloads.

* Moved the OperandSize argument for LoadForOffset and similar methods
  on 32-bit ARM from being the first argument to being the second to
  last argument just to match other architectures, and to allow it to
  have a default value of kFourBytes.

TEST=Run on trybots of all architectures.

Martin Kustermann c8ebfcd739 [vm] Remove unused code related to RedirectionData
Since the transition from Source based to Kernel based frontend to the
Dart VM, we have not supported callable redirecting factories. This has
caused all removed code in this CL to be unused and untested!

The support for reifing redirection related information would mainly be
used by embedder / dart:mirrors. Right now its not used by anyone and
the kernel support was never implemented.

I suggest we remove the unused and untested code until a decision has
been made that we actually want to support it - in which case it can be
properly implemented, possibly by re-using some of the deleted code in
this CL.

TEST=CL removes unused code, no test result changes.

Daco Harkes 9f96aeda6f [test/ffi] Add C++ unit tests for all target ABIs
This CL introduces unit tests for the Native* classes in compiler/ffi
that can run for all supported target ABIs on any host architecture.

The unit tests are compiled for all target ABIs with
`tools/build.py run_ffi_unit_tests` and run for all target ABIs with
`tools/test.py ffi_unit`.

The unit test and tested code do not conceptually depend on having a
DartVM. The tests are compiled with a custom `dart::Zone` and
`platform/`. This enables compiling for all `TARGET_ARCH_*` and
`TARGET_OS_*` on any host, and running unit tests for all target ABIs
on any host.

Because the `run_ffi_unit_tests` executables do not include the DartVM
their build is quick (<10seconds) and they are small (~6MB) when
compared to `run_vm_tests` (~250MB).

The tests are added to the existing FFI QEMU bot to prevent adding an
extra bot which would add checkout overhead.

The unit tests themselves are set up to be fairly similar to vm/cc
tests. The only difference is the NativeCallingConvention tests which
are set up with `.expect` files for easy inspection and updating.

Aske Simon Christensen 1ab705f60c [vm] Require all recognized methods to be marked with pragma.
Adds a @pragma("vm:recognized", <kind>) to all recognized methods, where
<kind> is one of "intrinsic", "graph" or "other", corresponding to the
kind of recognized method.

When running in debug mode, it is checked that all recognized methods
are marked with the correct kind of pragma, and that all methods marked
with the pragma are in fact recognized.

This enables kernel-level analyses and optimizations to query whether
a method is recognized by the VM.

Tess Strickland cd7d31950e [vm/compiler] Perform cleanups in subtype test cache stubs.
This CL adds the result register used for subtype test cache stubs to
TypeTestABI. This avoids the hardcoding of the register per-architecture
and allows GenerateCallSubtypeTestStub to be unified into a single
implementation for non-IA32 architectures.

Since the register arguments to GenerateCallSubtypeTestStub were always
either kNoRegister or the same TypeTestABI register across all calls,
those arguments are removed and the appropriate TypeTestABI registers
are considered hardcoded input registers and either implicitly (for
non-IA32) or explicitly (via the stack on IA32) passed to the subtype
tests cache stub being called.

TEST=Tested using our existing test cases, running debug (if available)
or release (if no debug available) trybots for all architectures.

Jens Johansen 2928af2b12 [kernel] Remove unused Class.level, ClassLevel enum and shift Library.flags down
ClassLevel and Class.level have been unused for (at least) years.
This CL removes them.
Library.flags furthermore had the first bit unused after the 'external'
flag was removed (last year I think).
This CL shifts it down so the actual flags doesn't start at bit 1.

This is a follow-up to

mostly changing the library nnbd bit encoding so that weak is uniquely
represented as "00" which is the default when nothing else is set.

Clement Skau c486a07b02 [VM] Fixes yield* exception handling in sync*.
This adds a mechanism similar to that used in async functions where
exceptions are caught in the synthetic code and passed into the
generated body to be rethrow'n.
This ensures the exception is throw'n from the same place as the
original yield*, as per the spec.
