Not NFC: changes some of the demangling tree schemata (in
interest of regularity and expressivity) and, incidentally,
improves support for initializer manglings.
The main schema change is that Path is now gone, and instead
the first child of an entity is its context. All contexts
are now labelled with their kind (variable/function/etc.)
rather than that being much more obscure or missing.
A secondary change is that the top-level node is now a
single node with the <global> and all its attributes as
children, rather than being weirdly sibling-linked.
Also, the representation has changed so that nodes link
only to their children, not to siblings or parents, which
means that it is no longer necessary to clone nodes when
replacing substitutions.
Finally, dump/print was brought in from swift-demangler
and made part of the core API for debugging purposes.
Swift SVN r11470
Added a new DiagnosticOptions class to swiftBasic, and added a DiagnosticOptions member to CompilerInvocation.
Added a static ParseDiagnosticArgs function to parse diagnostic-related arguments.
Added -verify to FrontendOptions.td, and added support for parsing -verify in ParseDiagnosticArgs.
Updated frontend_main() to enable and trigger the DiagnosticVerifier when -verify is passed.
Swift SVN r11318
Removed CompilerInvocation::TargetTriple and replaced it with CompilerInvocation::TargetOpts, a TargetOptions object.
Added a static ParseTargetArgs function to set up TargetOptions, and moved handling of -target into that function.
Swift SVN r11288
- Added a couple of new targets:
- libswiftDriver, which contains most of the driver implementation
- swift_driver, which produces the actual executable
- Added centralized version information into libswiftBasic.
- Added a new "Driver Design & Internals" document, which currently describes
the high-level design of the Swift driver.
- Implemented an early version of the functionality of the driver, including
versions of the Parse, Pipeline, Bind, Translate, and Execute driver stages.
Parse, Pipeline, and Bind are largely implemented; Translate and Execute are
early placeholders. (Translate produces "swift_driver --version" and "ld -v"
commands, while Execute performs all subtasks sequentially, rather than in
parallel.)
This is just the starting point for the Swift driver. Tests for the existing
behavior are forthcoming.

iVars of a given type should be unique by name and so in certain cases, their types will not actually add information to a consumer of the demangled string
This mode is mostly useful for LLDB. When searching for a field offset by name in a generic scenario, the search can succeed or fail depending on whether archetypes are
obtained through the Demangler ("A","B","C") or through the module (which will vend proper archetype names when poked the right way)
This mode removes that ambiguity
Swift SVN r10761
The constraint solver statistics now tell us which of the constraint
systems we are solving were the largest. This lets us look at what the
solver does with that constraint system without piling on the
debugging spew.
Swift SVN r10638
For every global pattern binding, emit a lazy initializer token and function that initializes the global variables in that binding. For each of those vars, create an accessor that Builtin.once's the lazy initializer before producing the address. Hide this all behind a switch till the surrounding serialization and IRGen infrastructure catches up.
Swift SVN r10511
Some work needs to be done on static member lookup and bitwise operations, but what's implemented now isn't a regression from what we have (except for an unfortunate case in Foundation.swift where we need to fully qualify a constant in a single-element NS_OPTIONS).
Swift SVN r10471
Apply the same prefix-chopping logic as for NS_ENUM to produce static property names to put inside the Swift type we create. For now, continue importing NS_OPTIONS as structs with a single integer field; in the short term it's easy to put a C-like interface over them this way.
Swift SVN r10434
A problem with name lookup from Clang module contexts <rdar://problem/15410928> means I have to disable a ~= overload in the ObjectiveC overlay. Other than that, NS_ENUM import should be ready to go.
Swift SVN r10018
Also remove the SourceLoc parameter from addNewSourceBuffer(). In llvm::SourceMgr
it is used to indicate textual inclusion, which we don't have in swift.
Swift SVN r10014
When we see an enum declaration in the Clang importer, look at its source location to see if it was produced as part of an NS_ENUM macro expansion. If so, take the 'Enum' route through the Clang importer and import it as a Swift enum. This will break things until we have end-to-end support for Clang-imported enums, so hide it behind an -import-ns-enum switch for now.
Swift SVN r9951
The underlying mechanism uses darwin's libcache library (if not building on darwin there is a default implementation).
This was originally introduced in SourceKit, but we are moving it to libswiftBasic so it can be utilized by libswiftIDE
for caching code-completion results.
Swift SVN r9610
This checkin extends the Demangler to allow printing sugar on demangled types
Namely, it introduces a DemanglerOptions class with just one field SynthesizeSugarOnTypes which has the same functionality as PrintOptions::SynthesizeSugarOnTypes
This changes outputs like _TtGSqC5sugar7MyClass_ ---> swift.Optional<sugar.MyClass> into _TtGSqC5sugar7MyClass_ ---> sugar.MyClass?
By default this flag is false, so that existing clients of the Demangler API do not break
OTOH, the command-line tool swift-demangle flags sets the flag to true, unless the -no-sugar option is passed on the command-line
Test cases included
Swift SVN r9502
If we're using emitExprInto to emit a LoadExpr, we can handle that by emitting a copy_addr from the underlying lvalue to the initialization instead of building and storing the rvalue, which plays better with the direction we're taking for value semantics optimizations.
This is currently guarded behind a flag -enable-silgen-lvalue-peepholes because it introduces a miscompile in the stdlib that crashes some tests; requires further investigation before making live.
Swift SVN r9027
This is only useful for unique-identification uses of the mangler, like in SourceKit,
which has to deal with invalid code.
Since this is not related to ABI, we can change the encoding anytime we want.
