Peter von der Ahé 16aa720d27 Remove compiling platform.dill from patch_sdk.dart
This separates compiling platform.dill files from the patch_sdk.dart
script. The motivation for that is that I'm working on reading patch
files directly from Fasta, so we can completely remove the build step
for generating patched_sdk and dart2js_patched_sdk.

Short-term this should allow Paul to add a strong-mode version of
platform.dill without causing to many conflicts with my work on
patches.

Samir Jindel 7bf835b9d5 Fix many bugs with closure conversion in checked mode.
Summary:

Previously, we use the "Vector" type in the kernel tree for the result of the
"VectorCreation" operation as as the parameter type for converted closure
functions. In the VM, we use the "Context" type instead, which the VM treats a
little differently than normal Dart-visible types, and it doesn't not handle
type checks against it correctly, breaking all closure converted code running in
checked mode.

Now, Since we are forced to use dynamic to represent the types of elements of
the context, we may as well just use dynamic for the context type itself.

Previously, we did not correct handle converted closure type checks for closures
that capture type parameters. The way we handled these type checks also had
several latent bugs that prevented type parameters being handled properly.

Now, we handle type parameters for converted closures similarly to normal
closures, and the places we treat them specially are fewer and more integrated
with the rest of the closure type checking code.

There is still a problem where assignments to captured variables are not
checked, because they are transformed to assignments into the context, whose
elements are necessarily untyped. This breaks many co19 tests, which expect type
errors on these assignments. The example below should error in checked mode, but
after closure conversion is runs with no errors.

int b;
bool c;
(() { b = c; })()

Test Plan:

- All test cases in "pkg/kernel/testcases/closures" now run in checked mode.

- Added a test "closures_types.dart" to check that captured type parameters are
  handled correctly in the converted closures' signature types.

Samir Jindel 6c5d1fba95 [kernel] Support for top-level generic functions.
Summary:

Previously, there was no support for generic methods in kernel. This prevented
us from being able to pass captured type arguments to the target top-level
function in converted closures, so these type arguments were always instantiated
to 'dynamic'.

Now, we save the type arguments to the closure creation operation in the
context, and read them out and forward them appropriately in closure wrapper
function. Since fasta doesn't currently support generic methods (their type
parameters are replaced by 'dynamic'), only top-level generic functions can
surface in kernel, as they are generated by closure conversion of closures that
capture type parameters of a class.

My focus here is enabling closure conversion to work in only these cases, and as
such, the code has some temporary "hacks" in the VM that may not work for
generic member functions or generic closures when they are enabled in fasta.

Test Plan:

I ran all the tests in closures/, and those which were previously expected to
crash due to missing VM support now pass and produce correct results.

Further testing is paused until we understand why the recent commit "[kernel]
Insert kernel bodies into VM heap" has broken all these tests.

Samir Jindel e80b42a235 Fix parsing of ClosureCreation kernel nodes in VM.
Summary:

Previously, the VM would crash when it encountered a ClosureCreation node
because it was not aware of the new type arguments field.

Now, it skips the type arguemnts field, which allows many tests to pass again,
even though it doesn't correct forward the type arguments at runtime.

Test Plan:

Removed expected failure lines for all the tests added in my prior
CL (introducing the new field).

Samir Jindel 4d7490c609 Preserve type variables in closure conversion.
Summary:

Previously, we filled in all occurrences of captured type variables with either
"dynamic" or their bound, if they had one.

Now, we add extra type parameters to the top-level function corresponding to the
closure, and pass in the corresponding arguments as type arguments to the
"MakeClosure" operation.

Test Plan:

Updated [type_variables.dart] and added a new test case to it.

Dmitry Stefantsov 5475240725 Add support for converted closures with explicit contexts to VM
The closure-conversion transformation is not enabled yet.  This commit
only adds the support for it to FlowGraphBuilder and
StreamingFlowGraphBuilder.  More work should be done before enabling the
transformation; most mportantly, the 'platform.dill' file that is used
in the Kernel isolate and is loaded by VM for linking with executed
programs should be separated.  The former should receive a file not
touched by the transformation, and the latter should receive a
transformed one.

Sigmund Cherem 610d081947 Tweak public APIs and use them in patch_sdk, dart2js, and kernel-service.
This CL tweaks the public APIs in package:front_end, and
starts using those APIs outside the package. For example, this
removes 9 uses of DillTarget, so it is not longer mentioned
outside pkg/front_end and the analyzer_target.

Actual changes:
 - in package:front_end

   * added kernel_generator_impl: new file contains code that
     used to be in kernel_generator. Code has some modifications:
     it uses a single canonical-root when loading summaries, and
     it supports generating both outlines and kernel in one go.

   * removed code that didn't belong here:
     a. most of calculating deps for .GN moved to patch_sdk
     b. vm-specific outcomes moved to kernel-service

   * updated how `native` is implemented, so we can more easily
     support dart2js and ddc

   * updated how we check where `int`, `bool`, etc can be implemented.

   * added support "hermetic mode" in modular builds
     ('chaseDependencies = false' option)

   * moved `trim` step out of fasta, and for now call it only within
     the public API. This is not yet exposed, and I stopped covering it in
     most tests (now only covered in shaker tests). The plan is to add
     tests for the public API covering this in the future.

   * removed `uriToSource` when serializing outlines

   * added unit tests for public APIs

 - patch_sdk
   * use the public API to craete platform.dill, outline.dill (now
     500K insted of 3Mb because it excludes sources), and vmservice_io.dill
   * moved here logic internal to .GN

 - kernel service
   * use the public API
   * moved here logic that depends on VM internals (e.g. status enum,
     compilation results)

 - package:compiler
   * use the public API in tools and unit tests
   * simplified patched-sdk generation: no more extending fasta's internals

 - package:kernel
   * fix bug in deserialization: initializers and other lists were
     overwritten accidentally with external definitions.
   * updated unit tests, moved shared logic to frontend/src/fasta/testing

Konstantin Shcheglov bdedd6768b Add a way to use shared CanonicalName root to deserialize Program.
This allows for example to add SDK into a Program, then load the
"incomplete" Program A that has only the library A, and name sequences
that references SDK classes. Because we look into the nameRoot which
aleady has SDK CanonicalName(s), we can find these names while filling
the link table and use references which point to the existing SDK
AST nodes.  Then we can load another set of library cycles, etc.

At the end we have a set of self-consistent libraries that we can
feed into DillTarget/DillLoader and resolve anothersource target
against it.

This CL introduces Fasta's first type inference rule, and hooks it up
to all the necessary testing infrastructure.  The rule is that a local
variable whose initializer is an integer literal should have an
inferred type of int.

Only variables occurring at top level within a method are inferred (we
don't yet recurse inside sub-blocks).

Additional type inference rules will be added in follow-up CLs.

Dmitry Stefantsov 9ab86da19c Add Vector type to Kernel
There are four operations that work on Vectors: Vector creation, looking
up an item in a Vector, assigning a value to an item in a Vector, and
copying a Vector. The first three operations are allowed to only use
integer literals as number operands (length for Vector creation, index
for item lookup and assignment). Corresponding AST nodes are created for
these operations.

Vectors are used to represent contexts in Closure Conversion. The parent
context is stored as item 0 in its children contexts. The "golden" tests
for this transformation are adjusted accordingly.

The support for Vectors is added to ast-to-text, ast-to-binary, and
binary-to-ast transformations.

Asger Feldthaus 8bfc4b47c0 Implement canonical name scheme in kernel.
This adds a class CanonicalName that can represent a library, class,
or member.  All references now go through a Reference object, which is
linked to both the AST node and its CanonicalName, so either can be
created first.

dartk now accepts multiple input files:
- If multiple dart files are given, they are all compiled.
- If multiple binaries are given, they are linked together.
Mixed dart and binary input is not supported by dartk.

dartk now has a flag --include-sdk which includes the entire SDK in
the output.  This is so the SDK can be compiled alone and then linked.

Example of compiling separately and then linking:
  dartk foo.dart -o foo.dill
  dartk main.dart -o main.dill
  dartk --include-sdk -o sdk.dill
  dartk main.dill foo.dill sdk.dill --target=vm --link -o program.dill

dartk still has incredibly slow cold start due to the analyzer loading
the dart sdk, so this does not actually speed things up at the moment.

Dmitry Stefantsov d5e2fcb430 Merge the work on Generic Types Reification from 'dart-lang/reify' repo
This CL adds the work done at https://github.com/dart-lang/reify to SDK.
The commit that is used for the merge is
a2066a68374d49de92ff75f5e1ffc36335fd9451 (Nov 23, 2016). The code is
adjusted to respect the changes of the kernel package in SDK since that
commit.

The reify transformation is run by specifying 'vmreify' target to
'dartk'. The transformation requires its runtime library to present in
the program being transformed. The library is found in its default
location in SDK checkout if 'dartk' is run from its default location in
SDK checkout. To preserve the library in the output, TreeShaker is
disabled in 'vmreify' target.

The "golden" set of tests is also copied from 'dart-lang/reify'
repository, and the appropriate test suite is defined for it.

The bash script 'bin/reified_dart' from 'dart-lang/reify' is rewritten
as Dart script 'pkg/kernel/bin/reified_dart.dart'. It requires path to
'dartk' and path to SDK. Those are taken from their default locations in
SDK if 'reified_dart.dart' is run from its default location in SDK.

The added files were formatted using 'dartfmt' with default settings.
Additionally, the files were checked with 'dartanalyzer --strong'. The
necessary changes were made to fix the error messages. There are some
'hint' and 'error' messages left for some .dart files from the added
test cases, but they reflect intentional errors or conventions in those
files.
