So far using runtime i18n with ivy meant that you needed to use Closure and `goog.getMsg` (or a polyfill). This PR changes the compiler to output both closure & non-closure code, while the unused option will be tree-shaken by minifiers.
This means that if you use the Angular CLI with ivy and load a translations file, you can use i18n and the application will not throw at runtime.
For now it will not translate your application, but at least you can try ivy without having to remove all of your i18n code and configuration.

Currently in Ivy we pass both the raw and parsed selectors to the projectionDef instruction, because the parsed selectors are used to match most nodes, whereas the raw ones are used to match against nodes with the ngProjectAs attribute. The raw selectors add a fair bit of code that won't be used in most cases, because ngProjectAs is somewhat rare.
These changes rework the compiler not to output the raw selectors in the projectionDef, but to parse the selector in ngProjectAs and to store it on the TAttributes. The logic for matching has also been changed so that it matches the pre-parsed ngProjectAs selector against the list of projection selectors.

While investigating styling performance regressions, it was discovered
that a single `fn(...args)` operation was causing a performance hit
because the generated es5 `__spread` operation uses `[].concat` and
reads from the `arguments` values (which are not very efficient). This
patch changes that around to use `fn.apply` instead.

In order to optimize performance for styling-related operations in
Angular, debug counters need to be introduced. This patch adds various
counters to ngDevMode which are fired each time a styling-related
binding is updated.
PR Close#29579
The new styling algorithm in angular is designed to evaluate host
bindings stylinh priority in order of directive evaluation order. This,
however, does not work with respect to parent/sub-class directives
because sub-class host bindings are run after the parent host bindings
but still have priority. This patch ensures that the host styling bindings
for parent and sub-class components/directives are executed with respect
to the styling algorithm prioritization.

Simply adds a `debug` property to the array of create opcodes while inside
`readCreateOpCodes` in i18n. This `debug` property has a property called `operations`
that is a human-readable list of operations that will be performed, as derived
from the op codes themselves, and the view it's acting upon.

Prior to this change, all module metadata would be included in the
`defineNgModule` call that is set as the `ngModuleDef` field of module
types. Part of the metadata is scope information like declarations,
imports and exports that is used for computing the transitive module
scope in JIT environments, preventing those references from being
tree-shaken for production builds.
This change moves the metadata for scope computations to a pure function
call that patches the scope references onto the module type. Because the
function is marked pure, it may be tree-shaken out during production builds
such that references to declarations and exports are dropped, which in turn
allows for tree-shaken any declaration that is not otherwise referenced.

This commit removes code duplication where we had 2 versions of a
`flatten` utility. Moreover this change results in queries using
a non-recursive version of `flatten` which should result in a better
performance of query refresh operations.
PR Close#29547
In View Engine, we used to generate empty QueryLists for content queries on root
components (though we did not actually support populating these lists). We need
to keep this behavior in Ivy for backwards compatibility. Otherwise, components
that are sometimes used as root will fail if they are relying on content query
results to always be defined.

ivy's bindingUpdated instruction is using the assertNotEqual check to make
sure that NO_CHANGE value (of type Object) is not passed as a value to be
dirty-checked. In practice it means that any value passed as a binding
value would be compared to the NO_CHANGE object.
It turns out that the assertNotEqual is using == and given
that binding values are of different type and we always compare it to the
NO_CHANGE object we were doing lots of type coercion. It resulted in calls
to expensive types conversions and calls to Object.toString().
A profiler reported ~15% of the self time spent in the assertNotEqual
but it turns out that removing type coercion speeds up Material Chips with
input scenario much more (~40ms down to ~20ms).
This PR introduces new assert method `assertNotSame` that uses strict equality
check. The new assertion is used in binding instructions to compare to
NO_CHANGE object reference.

This fix corrects a bug where we were passing a binding _value_
in place of an expected binding index. This reulted in the binding

Previously, only directives and services with generic type parameters
would emit `any` as generic type when emitting Ivy metadata into .d.ts
files. Pipes can also have generic type parameters but did not emit
`any` for all type parameters, resulting in the omission of those
parameters which causes compilation errors.
This commit adds support for pipes with generic type arguments and emits
`any` as generic type in the Ivy metadata.

This patch is the first of a few patches which separates the
styling logic between template bindings (e.g. <div [style])
from host bindings (e.g. @HostBinding('style')). This patch
in particular introduces a series of host-specific styling
instructions and changes the existing set of template styling
instructions not to accept directives. The underyling code (which
communicates with the styling algorithm) still works as it did
before.
This PR also separates the styling instruction code into a separate
file and moves over all other instructions into an dedicated
instructions directory.

Prior to this change, we always recompile all Components/Directives/Pipes even if they were AOT-compiled and had no overrides. This is causing problems in case we try to recompile a Component with "templateUrl" or "styleUrls" (which were already resolved in case of AOT) and generally this unnecessary work that TestBed was doing is not required. This commit adds extra logic to check whether a Component/Directive/Pipe already have compiled NG def (like ngComponentDef) and whether there are no overrides present - in this case recompilation is skipped. Recompilation is also skipped in case a Component/Directive has only Provider overrides - in this situation providers resolver function is patched to reflect overrides. Provider overrides are very common in g3, thus this code path ensures no full recompilation.

Fixes host listeners being inherited twice, if the sub class has its own `propMetadata`. This is related to #29170 which fixed something similar, however all of the test cases there had a super class with some metadata and a sub class that didn't have any. The issue manifested itself in the `MatTreeToggle` which inherits a listener from the `CdkTreeToggle` and adds an extra `Input` of its own, causing the listener to be added twice.

Angular Ivy interprets inline static style/class attribute values as instructions that
are processed whilst an element gets created. Because these inline style values are
referenced by style/class bindings, their inline style values are applied at a later
stage. Despite them being eventually applied, their values should be applied earlier
before any directives are instantiated so that directive code can rely on any inline
style/class changes.
This patch ensures that all static style/class attribute values are applied (rendered)
on the element before directives are instantiated.

Previously, ngtsc would resolve forward references while evaluating the
bootstrap, declaration, imports, and exports fields of NgModule types.
However, when generating the resulting ngModuleDef, the forward nature of
these references was not taken into consideration, and so the generated JS
code would incorrectly reference types not yet declared.
This commit fixes this issue by introducing function closures in the
NgModuleDef type, similarly to how NgComponentDef uses them for forward
declarations of its directives and pipes arrays. ngtsc will then generate
closures when required, and the runtime will unwrap them if present.
