This adds an argument to allow negating `-whole-module-optimization`.
This is useful for cases where it's easier to add an extra flag to your
swiftc invocation rather than removing the original one.
Add support in the driver and frontend for macCatalyst target
targets and library search paths.
The compiler now adds two library search paths for overlays when compiling
for macCatalyst: one for macCatalyst libraries and one for zippered macOS
libraries. The macCatalyst path must take priority over the normal macOS path
so that in the case of 'unzippered twins' the macCatalyst library is
found instead of the macOS library.
To support 'zippered' builds, also add support for a new -target-variant
flag. For zippered libraries, the driver invocation takes both a -target and a
-target-variant flag passes them along to the frontend. We support builds both
when the target is a macOS triple and the target variant is macCatalyst and
also the 'reverse zippered' configuration where the target is macCatalyst and the
target-variant is macOS.
Unless you do this, the flag has no effect when used with the driver;
it only worked in conjunction with -Xfrontend.
Noticed while working on <rdar://problem/58490723>.
Restructure fine-grained-dependencies to enable unit testing
Get frontend to emit correct swiftdeps file (fine-grained when needed) and only emit dot file for -emit-fine-grained-dependency-sourcefile-dot-files
Use deterministic order for more information outputs.
Set EnableFineGrainedDependencies consistently in frontend.
Tolerate errors that result in null getExtendedNominal()
Fix memory issue by removing node everywhere.
Break up print routine
Be more verbose so it will compile on Linux.
Sort batchable jobs, too.
Adds a tool `swift-symbolgraph-extract` that reads an existing Swift
module and prints a platform- and language-agnostic JSON description of
the module, primarly for documentation.
Adds a small sub-library `SymbolGraphGen` which houses the core
implementation for collecting relevant information about declarations.
The main entry point is integrated directly into the driver as a mode:
the tool is meant to be run outside of the normal edit-compile-run/test
workflow to avoid impacting build times.
Along with common options for other tools, unique options include
`pretty-print` for debugging, and a `minimum-access-level` options for
including internal documentation.
A symbol graph is a directed graph where the nodes are symbols in a
module and the edges are relationships between them. For example, a
`struct S` may have a member `var x`. The graph would have two nodes for
`S` and `x`, and one "member-of" relationship edge. Other relationship
kinds include "inherits-from" or "conforms to". The data format for a
symbol graph is still under development and may change without notice
until a specificiation and versioning scheme is published.
Various aspects about a symbol are recorded in the nodes, such as
availability, documentation comments, or data needed for printing the
shapes of declarations without having to understand specifics about the
langauge.
Implicit and public-underscored stdlib declarations are not included by
default.

* Ignore -wmo when passing -dump-ast
* Cleanup on driver diagnostics
* Remove the FIXME.
* Add support for ignoring `-index-file`
* Revert unrelated formatting changes
* Revert back to only ignoring `-wmo`
Ignoring both `-wmo` and `-index-file` will be harder than just `-wmo`. This is because when calling the compiler and passing `-index-file` after `-dump-ast`, the option gets un-ignored by `Driver::buildOutputInfo`. Therefore, we will just ignore `-wmo` for now.
* Add tests, inspired by `Driver/batch_mode_with_WMO_or_index.swift`
autolink-extract is needed on ELF (and windows-cygnus). However, WASM
also has gone down this path and did not actually indicate that it
needed the autolink extract handling. Extract the handling check into a
variable which helps readability.
Add various target-specific and compiler-determined paths to the output
of `-print-target-info`, such as the runtime resource path, SDK path, and
runtime library paths.
