Add ExecuteSILPipelineRequest which executes a
pipeline plan on a given SIL (and possibly IRGen)
module. This serves as a top-level request for
the SILOptimizer that we'll be able to hang
dependencies off.
Rather than registering individual IRGen passes
when we want to execute them, store function
pointers to all the pass constructors on the
ASTContext. This will make it easier to requestify
the execution of pass pipelines.
Remove the option to switch off nested types tables. In a world where
re-entrant direct lookup will cause deserialization to fail (or worse),
disabling these tables will only lead to further instability in the
compiler.
We were previously doing this for the REPL, but
not for swift-ide-test. Move the assignment into
the frontend to make sure its always applied, and
inline `createREPLFile` while we're here.
Instead of interleaving typechecking and parsing
for SIL files, first parse the file for Swift
decls by skipping over any intermixed SIL decls.
Then we can perform type checking, and finally SIL
parsing where we now skip over Swift decls.
This is an intermediate step to requestifying the
parsing of a source file for its Swift decls.
The REPL was using the CompilerInstance to stash this parameter, then it would immediately move it into IRGen. Drop the setter and pass this data directly.
Rather than parsing all delayed bodies for
`-dump-parse` once we finish parsing, tell the
parser not to delay any bodies. This then allows
us to remove `DelayedDeclLists` from
PersistentParserState.
- Introduce ide::CompletionInstance to manage CompilerInstance
- `CompletionInstance` vends the cached CompilerInstance when:
-- The compiler arguments (i.e. CompilerInvocation) has has not changed
-- The primary file is the same
-- The completion happens inside function bodies in both previous and
current completion
-- The interface hash of the primary file has not changed
- Otherwise, it vends a fresh CompilerInstance and cache it for the next
completion

When symbols are moved to this module, this module declares them as HIDE
for the OS versions prior to when the move happened. On the other hand, the
original module should declare ADD them for these OS versions. An executable
can choose the right library to link against depending on the deployment target.
This is a walk-around that linker directives cannot specify other install
name per symbol, we should eventually remove this.
Name binding can trigger swiftinterface compilation, which creates
a new ASTContext and runs a compilation job. If the compiler was
run with -stats-output-dir, this could trigger an assertion because
SharedTimer is not re-entrant.
Fix this by replacing all direct uses of SharedTimer in the frontend
with FrontendStatsTracer. SharedTimer is still used to _implement_
FrontendStatsTracer, however we can collapse some of the layers in
the implementation later. Many of the usages should also become
redundant over time once more code is converted over to requests.
Frontend outputs source-as-compiled, and source-ranges file with function body ranges and ranges that were unparsed in secondaries.
Driver computes diffs for each source file. If diffs are in function bodies, only recompiles that one file. Else if diffs are in what another file did not parse, then the other file need not be rebuilt.
De-duplicate TypeCheckingFlags, TypeChecker's Options, and the TypeChecker-Oriented FrontendOptions into a dedicated TypeCheckerOptions type. This moves a bunch of configuration state out of the type checker and into the ASTContext where it belongs.
- Use `performParseAndResolveImportsOnly()` to invoke the frontend
- Do `bindExtensions()` in `ide::typeCheckContextUntil()`
- Typecheck preceding `TopLevelCodeDecl`s only if the compleiton is in
a `TopLevelCodeDecl`
- Other related tweaks

Educational notes are small pieces of documentation which explain a concept
relevant to some diagnostic message. If -enable-descriptive-diagnostics is
passed, they will be printed after a diagnostic message if available.
Educational notes can be found at /usr/share/doc/diagnostics in a
toolchain, and are associated with specific compiler diagnostics in
EducationalNotes.def.
