John McCall c2f18315ff Move ASTRecordReader into its own header; NFC.
AbstractBasicReader.h has quite a few dependencies already,
and that's only likely to increase.  Meanwhile, ASTRecordReader
is really an implementation detail of the ASTReader that is only
used in a small number of places.

I've kept it in a public header for the use of projects like Swift
that might want to plug in to Clang's serialization framework.

I've also moved OMPClauseReader into an implementation file,
although it can't be made private because of friendship.

Rainer Orth 09d890d728 Move LangStandard*, InputKind::Language to Basic
This patch is a prerequisite for using LangStandard from Driver in
https://reviews.llvm.org/D64793.

It moves LangStandard* and InputKind::Language to Basic.  It is mostly
mechanical, with only a few changes of note:

- enum Language has been changed into enum class Language : uint8_t to
  avoid a clash between OpenCL in enum Language and OpenCL in enum
  LangFeatures and not to increase the size of class InputKind.

- Now that getLangStandardForName, which is currently unused, also checks
  both canonical and alias names, I've introduced a helper getLangKind
  which factors out a code pattern already used 3 times.

The patch has been tested on x86_64-pc-solaris2.11, sparcv9-sun-solaris2.11,
and x86_64-pc-linux-gnu.

There's a companion patch for lldb which uses LangStandard.h
(https://reviews.llvm.org/D65717).

While polly includes isl which in turn uses InputKind::C, that part of the
code isn't even built inside the llvm tree.  I've posted a patch to allow
for both InputKind::C and Language::C upstream
(https://groups.google.com/forum/#!topic/isl-development/6oEvNWOSQFE).

Duncan P. N. Exon Smith 1da7eac87c Frontend: Remove CompilerInstance::VirtualFileSystem, NFC
Remove CompilerInstance::VirtualFileSystem and
CompilerInstance::setVirtualFileSystem, instead relying on the VFS in
the FileManager.  CompilerInstance and its clients already went to some
trouble to make these match.  Now they are guaranteed to match.

As part of this, I added a VFS parameter (defaults to nullptr) to
CompilerInstance::createFileManager, to avoid repeating construction
logic in clients that just wanted to customize the VFS.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Kristof Umann 549f9cd46f [analyzer] Evaluate all non-checker config options before analysis
In earlier patches regarding AnalyzerOptions, a lot of effort went into
gathering all config options, and changing the interface so that potential
misuse can be eliminited.

Up until this point, AnalyzerOptions only evaluated an option when it was
querried. For example, if we had a "-no-false-positives" flag, AnalyzerOptions
would store an Optional field for it that would be None up until somewhere in
the code until the flag's getter function is called.

However, now that we're confident that we've gathered all configs, we can
evaluate off of them before analysis, so we can emit a error on invalid input
even if that prticular flag will not matter in that particular run of the
analyzer. Another very big benefit of this is that debug.ConfigDumper will now
show the value of all configs every single time.

Also, almost all options related class have a similar interface, so uniformity
is also a benefit.

The implementation for errors on invalid input will be commited shorty.

Kristof Umann c83b0dda49 [analyzer][NFC] Fix some incorrect uses of -analyzer-config options
I'm in the process of refactoring AnalyzerOptions. The main motivation behind
here is to emit warnings if an invalid -analyzer-config option is given from
the command line, and be able to list them all.

In this patch, I found some flags that should've been used as checker options,
or have absolutely no mention of in AnalyzerOptions, or are nonexistent.

- NonLocalizedStringChecker now uses its "AggressiveReport" flag as a checker
    option
- lib/StaticAnalyzer/Frontend/ModelInjector.cpp now accesses the "model-path"
    option through a getter in AnalyzerOptions
- -analyzer-config path-diagnostics-alternate=false is not a thing, I removed it,
- lib/StaticAnalyzer/Checkers/AllocationDiagnostics.cpp and
    lib/StaticAnalyzer/Checkers/AllocationDiagnostics.h are weird, they actually
    only contain an option getter. I deleted them, and fixed RetainCountChecker
    to get it's "leak-diagnostics-reference-allocation" option as a checker option,
- "region-store-small-struct-limit" has a proper getter now.

David Blaikie ea4395ebcd Reapply "IntrusiveRefCntPtr -> std::shared_ptr for CompilerInvocationBase and CodeCompleteConsumer"
Aleksey Shlypanikov pointed out my mistake in migrating an explicit
unique_ptr to auto - I was expecting the function returned a unique_ptr,
but instead it returned a raw pointer - introducing a leak.

Thanks Aleksey!

Adrian Prantl bb165fb04d Introduce a PCHContainerOperations interface (NFC).
A PCHContainerOperations abstract interface provides operations for
creating and unwrapping containers for serialized ASTs (precompiled
headers and clang modules). The default implementation is
RawPCHContainerOperations, which uses a flat file for the output.

The main application for this interface will be an
ObjectFilePCHContainerOperations implementation that uses LLVM to
wrap the module in an ELF/Mach-O/COFF container to store debug info
alongside the AST.

Benjamin Kramer 3204b152b5 Replace push_back(Constructor(foo)) with emplace_back(foo) for non-trivial types
If the type isn't trivially moveable emplace can skip a potentially
expensive move. It also saves a couple of characters.


Call sites were found with the ASTMatcher + some semi-automated cleanup.

memberCallExpr(
    argumentCountIs(1), callee(methodDecl(hasName("push_back"))),
    on(hasType(recordDecl(has(namedDecl(hasName("emplace_back")))))),

                       has(constructExpr()))),
    unless(isInTemplateInstantiation()))

Ted Kremenek eeccb30b94 Add support for the static analyzer to synthesize function implementations from external model files.
Currently the analyzer lazily models some functions using 'BodyFarm',
which constructs a fake function implementation that the analyzer
can simulate that approximates the semantics of the function when
it is called.  BodyFarm does this by constructing the AST for
such definitions on-the-fly.  One strength of BodyFarm
is that all symbols and types referenced by synthesized function
bodies are contextual adapted to the containing translation unit.
The downside is that these ASTs are hardcoded in Clang's own
source code.

A more scalable model is to allow these models to be defined as source
code in separate "model" files and have the analyzer use those
definitions lazily when a function body is needed.  Among other things,
it will allow more customization of the analyzer for specific APIs
and platforms.

This patch provides the initial infrastructure for this feature.
It extends BodyFarm to use an abstract API 'CodeInjector' that can be
used to synthesize function bodies.  That 'CodeInjector' is
implemented using a new 'ModelInjector' in libFrontend, which lazily
parses a model file and injects the ASTs into the current translation
unit.  

Models are currently found by specifying a 'model-path' as an
analyzer option; if no path is specified the CodeInjector is not
used, thus defaulting to the current behavior in the analyzer.

Models currently contain a single function definition, and can
be found by finding the file <function name>.model.  This is an
initial starting point for something more rich, but it bootstraps
this feature for future evolution.

This patch was contributed by Gábor Horváth as part of his
Google Summer of Code project.

Some notes:

- This introduces the notion of a "model file" into
  FrontendAction and the Preprocessor.  This nomenclature
  is specific to the static analyzer, but possibly could be
  generalized.  Essentially these are sources pulled in
  exogenously from the principal translation.

  Preprocessor gets a 'InitializeForModelFile' and
  'FinalizeForModelFile' which could possibly be hoisted out
  of Preprocessor if Preprocessor exposed a new API to
  change the PragmaHandlers and some other internal pieces.  This
  can be revisited.

  FrontendAction gets a 'isModelParsingAction()' predicate function
  used to allow a new FrontendAction to recycle the Preprocessor
  and ASTContext.  This name could probably be made something
  more general (i.e., not tied to 'model files') at the expense
  of losing the intent of why it exists.  This can be revisited.

- This is a moderate sized patch; it has gone through some amount of
  offline code review.  Most of the changes to the non-analyzer
  parts are fairly small, and would make little sense without
  the analyzer changes.

- Most of the analyzer changes are plumbing, with the interesting
  behavior being introduced by ModelInjector.cpp and
  ModelConsumer.cpp.

- The new functionality introduced by this change is off-by-default.
  It requires an analyzer config option to enable.
