In a more specific scenario: Considering people use a custom TypeScript compiler host with `NGC`, they _could_ expect only posix paths in methods like `writeFile`. This at first glance sounds like a trivial issue that should be just fixed by the actual compiler host, but usually TypeScript internal API's just pass around posix normalized paths, and therefore it would be good to follow the same standards when passing JSON genfiles to the `CompilerHost`.
For normal TypeScript files (and TS genfiles), this is already consistent because those will be handled by the actual TypeScript `Program` (see `emitCallback`).

PR Close#26217
Currently, calling `downgradeModule()` more than once is not supported.
If one wants to downgrade multiple Angular modules, they can create a
"super-module" that imports all the rest and downgrade that.
This commit adds support for downgrading multiple Angular modules. If
multiple modules are downgraded, then one must explicitly specify the
downgraded module that each downgraded component or injectable belongs
to, when calling `downgradeComponent()` and `downgradeInjectable()`
respectively.
No modification is needed (i.e. there is no need to specify a module for
downgraded components and injectables), if an app is not using
`downgradeModule()` or if there is only one downgraded Angular module.

When compiling the flat-file version of the `@angular/core` we need to be aware
that we cannot rely upon imported names to access the ivy definition functions.
The compiler is already clever enough to use local function calls rather than
trying to add a namespaced import, but there is a problem if the local name of the
function is different to the exported name. This is the case for functions that
are not part of the public API, and so are exported under a barred-O private alias.
In `@angular/core` the only decorations in use are `@NgModule` and `@Injectable`.
There are no directives, components, pipes, etc.
Since `defineInjectable` is part of the public API of `@angular/core`, the compiler
is able to generate code that references the original non-barred-O version of the
function.
But the `defineNgModule` is not part of the public API and so the compiler must
generate code that refers to it by the private barred-O version of the function.
This commit imports and then re-exports this barred-O version of `defineModule` to
ensure that the symbol is available in the local scope of the flat-file versions of
the `@angular/core` library.

For each package entry-point there is only one format that

1) The `DecorationAnalyzer now analyzes all source files, rather than just
the entry-point files, which fixes#26183.
2) The `DecoratorAnalyzer` now runs all the `handler.analyze()` calls
across the whole entry-point *before* running `handler.compile()`. This
ensures that dependencies between the decorated classes *within* an
entry-point are known to the handlers when running the compile process.
3) The `Renderer` now does the transformation of the typings (.d.ts) files
which allows us to support packages that only have flat format
entry-points better, and is faster, since we won't parse `.d.ts` files twice.

The `NgModule` handler generates `R3References` for its declarations, imports,

in the .d.ts file may be very different to the import needed between .js

This commit introduces generateSetClassMetadataCall(), an API in ngtsc
for generating calls to setClassMetadata() for a given declaration. The
reflection API is used to enumerate Angular decorators on the declaration,
which are converted to a format that ReflectionCapabilities can understand.
The reflection metadata is then patched onto the declared type via a call
to setClassMetadata().
This is simply a utility, a future commit invokes this utility for
each DecoratorHandler.
Testing strategy: tests are included which exercise generateSetClassMetadata
in isolation.
PR Close#26860
This commit introduces the setClassMetadata() private function, which
adds metadata to a type in a way that can be accessed via Angular's
ReflectionCapabilities. Currently, it writes to static fields as if
the metadata being added was downleveled from decorators by tsickle.
The plan is for ngtsc to emit code which calls this function, passing
metadata on to the runtime for testing purposes. Calls to this function
would then be tree-shaken away for production bundles.
Testing strategy: proper operation of this function will be an integral
part of TestBed metadata overriding. Angular core tests will fail if this
is broken.

is safe to tree-shake away.
This commit adds a 'pure' flag to the output AST function call node,

This commit adds generation of .ngsummary.js shims alongside .ngfactory.js
shims when generated files are enabled.
Generated .ngsummary shims contain a single, null export for every exported
class with decorators that exists in the original source files. Ivy code
does not depend on summaries, so these exist only as a placeholder to allow
them to be imported and their values passed to old APIs. This preserves
backwards compatibility.
Testing strategy: this commit adds a compiler test to verify the correct
shape and contents of the generated .ngsummary.js files.

Originally, the ivy_switch mechanism used Bazel genrules to conditionally
compile one TS file or another depending on whether ngc or ngtsc was the
selected compiler. This was done because we wanted to avoid importing
certain modules (and thus pulling them into the build) if Ivy was on or
off. This mechanism had a major drawback: ivy_switch became a bottleneck
in the import graph, as it both imports from many places in the codebase
and is imported by many modules in the codebase. This frequently resulted
in cyclic imports which caused issues both with TS and Closure compilation.
It turns out ngcc needs both code paths in the bundle to perform the switch
during its operation anyway, so import switching was later abandoned. This
means that there's no real reason why the ivy_switch mechanism needed to
operate at the Bazel level, and for the ivy_switch file to be a bottleneck.
This commit removes the Bazel-level ivy_switch mechanism, and introduces
an additional TypeScript transform in ngtsc (and the pass-through tsc
compiler used for testing JIT) to perform the same operation that ngcc
does, and flip the switch during ngtsc compilation. This allows the
ivy_switch file to be removed, and the individual switches to be located
directly next to their consumers in the codebase, greatly mitigating the
circular import issues and making the mechanism much easier to use.
As part of this commit, the tag for marking switched variables was changed
from __PRE_NGCC__ to __PRE_R3__, since it's no longer just ngcc which
flips these tags. Most variables were renamed from R3_* to SWITCH_* as well,
since they're referenced mostly in render2 code.
Test strategy: existing test coverage is more than sufficient - if this
didn't work correctly it would break the hello world and todo apps.

The most recent Angular distributions have begun to use __decorate instead of Class.decorators.
This prevents `ngcc` from recognizing the classes and then fails to perform the transform to
ivy format.

// Inject ApplicationRef to make it eager...
function ApplicationModule(appRef) {
}
ApplicationModule = __decorate([
NgModule({ providers: APPLICATION_MODULE_PROVIDERS }),
__metadata("design:paramtypes", [ApplicationRef])
], ApplicationModule);
return ApplicationModule;
}());

Now `ngcc` recognizes `__decorate([...])` declarations and performs its transform.

Previously in Ivy, metadata for directives/components/modules/etc was
carried in .d.ts files inside type information encoded on the
DirectiveDef, ComponentDef, NgModuleDef, etc types of Ivy definition
fields. This works well, but has the side effect of complicating Ivy's
runtime code as these extra generic type parameters had to be specified
as <any> throughout the codebase. *DefInternal types were introduced
previously to mitigate this issue, but that's the wrong way to solve
the problem.
This commit returns *Def types to their original form, with no metadata
attached. Instead, new *DefWithMeta types are introduced that alias the
plain definition types and add extra generic parameters. This way the

Type constructors are static methods on component/directive types with
no runtime implementation. The methods are used during compilation to
enable inference of a component or directive's generic type parameters
from the types of expressions bound to any of their @Inputs. A type
constructor looks like:
class Directive<T> {
someInput: T;
static ngTypeCtor<T>(init: Partial<Pick<Directive<T>, 'someInput'>>): Directive<T>;
}
It can be used to infer a type for T based on the input:
const _dir = Directive.ngTypeCtor({someInput: 'string'}); // Directive<T>
