> Passing nullability rather than forcing kLegacy helps slightly reduce the number
> of Types in the VM and in snapshots.
> This allows to remove the kludge about declaration type of Null being kNullable.
> Also pass nullability when creating a simple type may help.
>
> Note that CFE is still producing super types and some interface types that are
> non-nullable, even with nnbd features disabled. But this should get fixed and
> further reduce the number of types in the snapshot.

This change allow builds to succeed on Arch Linux with python 2.7, 3.7.4
and 3.8. Otherwise it fails with python 3.7.4 and 3.8.

Using ord(byte) here is an error on python 3.x use a conditional
expression instead.
- create_archive.py
Using ord(byte) here is an error on python 3.x use a conditional

Use `as inst` syntax which is required by 3.x

- make_version.py
print >> sys.stderr syntax is not supported by 3.x use file=sys.stderr
and add `from __future__ import print_function`
vmhash.update requires a string use encode('utf-8')
versopm+cc+text.replace requires a str so use `decode`.
Test: No added tests as there are no behavioral changes.

Crashes come from assertion in ReturnTokens() and new_mask() in Eventhandler.
Another issue is when multiple serversockets bind to the same address, Socket will be reused to all Dart_Ports. But Socket didn't keep track of corresponding Dart Port.
When one of isolates is killed, finalizer wakes up and close most recent Dart Port that sends data.
After this cl, Socket may not be reused by different Dart Sockets. All Dart socket will has its own Socket object. But Sockets can have same fd.
This will guarantee finalizer will close right Dart Port.

Right now a message handler is taking care of detecting idle timeouts
and notifying the isolate (or rather it's heap) that a compaction can
start.
Once we move the heap to the isolate group, we should only notify the
heap that we're idle if *all* isolates are idle. As a preparatory step
we move the idle timer functionality into it's own class and make the
isolate own it.
When the heap gets moved from isolate to isolate group, we'll also move
the idle time handler.

We attempted to delete the file with service protocol information
immediately after retrieving the URI. However, the spawned process could
potentially still have that file open which will cause the deletion to
fail on Windows. Fix is to wait until the process closes before deleting
to ensure it's not holding onto the file.

This paves the way for removing the old constant evaluator from the VM,
by no longer supporting versions without front-end constant evaluation.
For the front-end test that tests old kernel versions on the newest VM,
the dill files for versions before 29 are deleted.
Version 29 is from 2019-08-16: eae781c73e

This CL
* adds a GN flag "include_dart2native" off by-default (switched on explicitly for our GN build)
* ensures every GN build of the "create_sdk" target has a working dart2native (except ia32)
* removes not-working dart2native script from ia32 dart-sdk (no AOT support in ia32)
* removes the "dartaotruntime" GN target, since it is the same as "dart_precompiled_runtime"
This should ensure every downstream consumer of the "create_sdk" GN target will
have a working version of dart2native.
For the particular "dart-sdk" we create on dart-sdk-{linux,windows,mac}
we will override the default AOT compiler&runtime with the product mode,
which produces smaller AOT snapshots and has smaller AOT runtime (making
the native executables significantly smaller)

Previously, before switching to compact encoding of bytecode
instructions, we had to align bytecode instructions by 4.
Since that time sections of bytecode binary were aligned.
However, this alignment doesn't work well in AOT mode if dill file
contains both bytecode and AST, as other metadata (such as obfuscation
prohibitions) may precede bytecode metadata and may make the whole
bytecode binary misaligned.
This results in incorrect calculation of section offsets,
failed assertion
assert(writer.offset - start == section.offset);
and VM may fail to load bytecode binary with error
bytecode_reader.cc: 1368: error: unreachable code
In order to fix these problems, extra alignment of bytecode
sections is removed.

This sets us up for migrating away from a dedicated timezone service
into a more general `fuchsia.intl.*`.
As a first step, let's use only one of the two equivalent FIDL service sets.
In fuchsia they are implemented by exactly the same handlers, so are equivalent
to the best of my knowledge.
Fixes#39174.

The LLVM code generator should only consume the serialized IR and not use any other VM functionality.
This CL adds a custom zone which can be used for the deserialized IR nodes and removes any
Dart_SetVMFlags/Dart_Initialize/ApiZone/... calls.
This works with the existing example:
% ninja -C out/ReleaseX64 codegen
% out/ReleaseX64/codegen runtime/llvm_codegen/test/codegen/Inputs/hello.sex
...
define void @"hello.dart::main"() {
