0b5ca510fb00eeb19ab82ebfd3c2585404bc9aa8 13-Sep-2013 David Blaikie <dblaikie@gmail.com> Remove unnecessary inclusion of Sema.h

Let me tell you a tale...

Within some twisted maze of debug info I've ended up implementing an
insane man's Include What You Use device. When the debugger emits debug
info it really shouldn't, I find out why & then realize the code could
be improved too.

In this instance CIndexDiagnostics.cpp had a lot more debug info with
Clang than GCC. Upon inspection a major culprit was all the debug info
describing clang::Sema. This was emitted because clang::Sema is
befriended by DiagnosticEngine which was rightly required, but GCC
doesn't emit debug info for friends so it never emitted anything for
Clang. Clang does emit debug info for friends (will be fixed/changed to
reduce debug info size).

But why didn't Clang just emit a declaration of Sema if this entire TU
didn't require a definition?

1) Diagnostic.h did the right thing, only using a declaration of Sema
and not including Sema.h at all.
2) Some other dependency of CIndexDiagnostics.cpp didn't do the right
thing. ASTUnit.h, only needing a declaration, still included Sema.h
(hence this commit which removes that include and adds the necessary
includes to the cpp files that were relying on this)
3) -flimit-debug-info didn't save us because of
EnterExpressionEvaluationContext, defined inline in Sema.h which fires
the "requiresCompleteType" check/flag (since it uses nested types from
Sema and calls Sema member functions) and thus, if debug info is ever
emitted for the type, the whole type is emitted and not just a
declaration.

Improving -flimit-debug-info to account for this would be... hard.
Modifying the code so that's not 'required to be complete' might be
possible, but probably only by moving EnterExpressionEvaluationContext
either into Sema, or out of Sema.h. That might be a bit too much of a
contortion to be bothered with.

Also, this is only one of the cases where emitting debug info for
friends caused us to emit a lot more debug info (this change reduces
Clang's DWO size by 0.93%, dropping friends entirely reduces debug info
by 3.2%) - I haven't hunted down the other cases, but I assume they
might be similar (Sema or something like it). IWYU or a similar tool
might help us reduce build times a bit, but analyzing debug info to find
these differences isn't worthwhile. I'll take the 3.2% win, provide this
small improvement to the code itself, and move on.

7247c88d1e41514a41085f83ebf03dd5220e054a 15-May-2013 David Blaikie <dblaikie@gmail.com> Use only explicit bool conversion operator

The most common (non-buggy) case are where such objects are used as
return expressions in bool-returning functions or as boolean function
arguments. In those cases I've used (& added if necessary) a named
function to provide the equivalent (or sometimes negative, depending on
convenient wording) test.

DiagnosticBuilder kept its implicit conversion operator owing to the
prevalent use of it in return statements.

One bug was found in ExprConstant.cpp involving a comparison of two
PointerUnions (PointerUnion did not previously have an operator==, so
instead both operands were converted to bool & then compared). A test
is included in test/SemaCXX/constant-expression-cxx1y.cpp for the fix
(adding operator== to PointerUnion in LLVM).

ff398965a5abfaf5bc47bc022876f56a28e5b9a7 11-Jul-2012 Argyrios Kyrtzidis <akyrtzi@gmail.com> Introduce a flag in SourceManager to treat non-system source files
as "volatile", meaning there's a high enough chance that they may
change while we are trying to use them.

This flag is only enabled by libclang.
Currently "volatile" source files will be stat'ed immediately
before opening them, because the file size stat info
may not be accurate since when we got it (e.g. from the PCH).
This avoids crashes when trying to reference mmap'ed memory
from a file whose size is not what we expect.

Note that there's still a window for a racing issue to occur
but the window for it should be way smaller than before.
We can consider later on to avoid mmap completely on such files.

But because ASTUnit caches global declarations during parsing before

28a83f57003469fb615ad27dd34bcf5b0a10da8c 10-Apr-2012 Argyrios Kyrtzidis <akyrtzi@gmail.com> [code-complete] Introduce CodeCompletionTUInfo which will be used for caching
code-completion related strings specific to a translation unit (ASTContext and related data)

CodeCompletionAllocator does such limited caching, by caching the name assigned
to a DeclContext*, but that is not the appropriate place since that object has
a lifetime that can extend beyond that of an ASTContext.

Introduce CodeCompletionTUInfo which will be always tied to a translation unit
to do this kind of caching and move the caching of CodeCompletionAllocator into this
object, and propagate it to all the places where it will be needed.

The plan is to extend the caching where appropriate, using CodeCompletionTUInfo,
to avoid re-calculating code-completion strings.

5e35693721364673f8196e4f5a370f56b92e6053 01-Dec-2011 Douglas Gregor <dgregor@apple.com> Introduce the notion of name visibility into modules. For a given
(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).

This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).

d3b74d9ca4f239a7a90ad193378c494306c57352 18-Nov-2011 Ted Kremenek <kremenek@apple.com> Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has
a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.

As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.

This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.

6aa52ec6b969faabf3764baf79d89810b8249a7e 27-Aug-2011 Douglas Gregor <dgregor@apple.com> Introduce support for a simple module import declaration, which
loads the named module. The syntax itself is intentionally hideous and
will be replaced at some later point with something more
palatable. For now, we're focusing on the semantics:
- Module imports are handled first by the preprocessor (to get macro
definitions) and then the same tokens are also handled by the parser
(to get declarations). If both happen (as in normal compilation),
the second one is redundant, because we currently have no way to
hide macros or declarations when loading a module. Chris gets credit
for this mad-but-workable scheme.
- The Preprocessor now holds on to a reference to a module loader,
which is responsible for loading named modules. CompilerInstance is
the only important module loader: it now knows how to create and
wire up an AST reader on demand to actually perform the module load.
- We search for modules in the include path, using the module name
with the suffix ".pcm" (precompiled module) for the file name. This
is a temporary hack; we hope to improve the situation in the
future.

f62d43d2afe1960755a1b5813cae1e5983bcac1b 19-Jul-2011 Douglas Gregor <dgregor@apple.com> Revamp the SourceManager to separate the representation of parsed
source locations from source locations loaded from an AST/PCH file.

Previously, loading an AST/PCH file involved carefully pre-allocating
space at the beginning of the source manager for the source locations
and FileIDs that correspond to the prefix, and then appending the
source locations/FileIDs used for parsing the remaining translation
unit. This design forced us into loading PCH files early, as a prefix,
whic has become a rather significant limitation.

This patch splits the SourceManager space into two parts: for source
location "addresses", the lower values (growing upward) are used to
describe parsed code, while upper values (growing downward) are used
for source locations loaded from AST/PCH files. Similarly, positive
FileIDs are used to describe parsed code while negative FileIDs are
used to file/macro locations loaded from AST/PCH files. As a result,
we can load PCH/AST files even during parsing, making various
improvemnts in the future possible, e.g., teaching #include <foo.h> to
look for and load <foo.h.gch> if it happens to be already available.

This patch was originally written by Sebastian Redl, then brought
forward to the modern age by Jonathan Turner, and finally
polished/finished by me to be committed.

01b6e31a62e2265849f4388b9be6be0a5d13348d 01-Jul-2011 Douglas Gregor <dgregor@apple.com> When we create a precompiled preamble, don't copy the
CompilerInvocation on the stack, because other objects (e.g., the
CompilerInstance) maintain an intrusive reference-counted pointer to
the CompilerInvocation. This doesn't matter in the normal case,
because we take back the CompilerInvocation. However, during crash
recovery, this leads to us trying to free an object on the stack, and
hilarity ensues. Fixes <rdar://problem/9652540>.

dca8ee8b7bc86076916a3a80f553f7a4e98c14af 06-May-2011 Douglas Gregor <dgregor@apple.com> Introduce a new libclang parsing flag,
CXTranslationUnit_NestedMacroInstantiations, which indicates whether
we want to see "nested" macro instantiations (e.g., those that occur
inside other macro instantiations) within the detailed preprocessing
record. Many clients (e.g., those that only care about visible tokens)
don't care about this information, and in code that uses preprocessor
metaprogramming, this information can have a very high cost.

151466a18671df9cfd9abd59ba53df35b1d687da 23-Nov-2010 Chris Lattner <sabre@nondot.org> Partially revert Doug's PCH validation patch (r98585).

This patch completely defeated the "passing in a prestat'd size
to MemoryBuffer" optimization, leading to an extra fstat call for
every buffer opened, in order to find out if the datestamp and size
of the file on disk matches what is in the stat cache.

I fully admit that I don't completely understand what is going on here:
why punish code when a stat cache isn't in use? what is the point of a
stat cache if you have to turn around and stat stuff to validate it?

To resolve both these issues, just drop the modtime check and check the
file size, which is the important thing anyway. This should also resolve
PR6812, because presumably windows is stable when it comes to file sizes.
If the modtime is actually important, we should get it and keep it on the
first stat.

This eliminates 833 fstat syscalls when processing Cocoa.h, speeding up
system time on -Eonly Cocoa.h from 0.041 to 0.038s.

diagnostic-capturing client lives as long as the ASTUnit itself
does. Otherwise, we can end up with crashes when we get a diagnostic
outside of parsing/code completion. The circumstances under which this
happen are really hard to reproduce, because a file needs to change
from under us.

389db16c63eec6ecfa9b235155252d8da766e94e 03-Nov-2010 Argyrios Kyrtzidis <akyrtzi@gmail.com> Implement -working-directory.

When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.

--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
file operations will be abstracted in the future for the reproduction mechanism.

FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

f5586f6b311c98e1022a8fe0609053849b70d323 16-Aug-2010 Douglas Gregor <dgregor@apple.com> When caching code completions for global declarations, keep track of
the usage type of each declaration result, then compare those types to
the preferred type of the completion. This provides parity in the
priority calculation between the code-completion results produced
directly from Sema and those cached by ASTUnit.

For the standard Cocoa.h (+ others) example, there's a penalty of 3-4
hundredeths of a second when caching the global results (for ~31,000
results), because we need an ASTContext-agnostic representation of
types for the comparison, and therefore we use... strings. Eventually,
we'd like to implement a more efficient ASTContext-agnostic encoding
of types.

type class, so that we can adjust priorities appropriately when the
preferred type for the context and the actual type of the completion
are similar.

This gets us one step closer to parity of the cached completion
results with the non-cached completion results.

87c08a5d6b9e1e44ae6f554df40139d3a6f60b33 14-Aug-2010 Douglas Gregor <dgregor@apple.com> Implement caching of code-completion results for macro definitions
when the CXTranslationUnit_CacheCompletionResults option is given to
clang_parseTranslationUnit(). Essentially, we compute code-completion
results for macro definitions after we have parsed the file, then
store an ASTContext-agnostic version of those results (completion
string, cursor kind, priority, and active contexts) in the
ASTUnit. When performing code completion in that ASTUnit, we splice
the macro definition results into the results provided by the actual
code-completion (which has had macros turned off) before libclang gets
those results. We use completion context information to only splice in
those results that make sense for that context.

With a completion involving all of the macros from Cocoa.h and a few other
system libraries (totally ~8500 macro definitions) living in a
precompiled header, we get about a 9% performance improvement from
code completion, since we no longer have to deserialize all of the
macro definitions from the precompiled header.

Note that macro definitions are merely the canary; the cache is
designed to also support other top-level declarations, which should be
a bigger performance win. That optimization will be next.

Note also that there is no mechanism for determining when to throw
away the cache and recompute its contents.

completion within the translation unit using the same command-line
arguments for parsing the translation unit. Eventually, we'll reuse
the precompiled preamble to improve code-completion performance, and
this also gives us a place to cache results.

Expose this function via the new libclang function
clang_codeCompleteAt(), which performs the code completion within a
CXTranslationUnit. The completion occurs in-process
(clang_codeCompletion() runs code completion out-of-process).

f4f6c9db68465b886ec2e596feaa6ecc782395a4 26-Jul-2010 Douglas Gregor <dgregor@apple.com> Introduce basic support for loading a precompiled preamble while
reparsing an ASTUnit. When saving a preamble, create a buffer larger
than the actual file we're working with but fill everything from the
end of the preamble to the end of the file with spaces (so the lexer
will quickly skip them). When we load the file, create a buffer of the
same size, filling it with the file and then spaces. Then, instruct
the lexer to start lexing after the preamble, therefore continuing the
parse from the spot where the preamble left off.

It's now possible to perform a simple preamble build + parse (+
reparse) with ASTUnit. However, one has to disable a bunch of checking
in the PCH reader to do so. That part isn't committed; it will likely
be handled with some other kind of flag (e.g., -fno-validate-pch).

As part of this, fix some issues with null termination of the memory
buffers created for the preamble; we were trying to explicitly
NULL-terminate them, even though they were also getting implicitly
NULL terminated, leading to excess warnings about NULL characters in
source files.

4ae8f298b1ea51b4c2234f9148e2e4349c9bdd23 18-Mar-2010 Douglas Gregor <dgregor@apple.com> Introduce the notion of a "preprocessing record", which keeps track of
the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.

The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.

Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.

Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

a88084b78fd4ca5d3d858c14b02414f8cc399f02 18-Feb-2010 Douglas Gregor <dgregor@apple.com> Rework how CIndex handles diagnostics. Rather than using a callback,
we attach diagnostics to translation units and code-completion
results, so they can be queried at any time.

To facilitate this, the new StoredDiagnostic class stores a diagnostic
in a serializable/deserializable form, and ASTUnit knows how to
capture diagnostics in this stored form. CIndex's CXDiagnostic is a
thin wrapper around StoredDiagnostic, providing a C interface to
stored or de-serialized diagnostics.

I've XFAIL'd one test case temporarily, because currently we end up
storing diagnostics in an ASTUnit that's never returned to the user
(because it contains errors). I'll introduce a temporary fix for this
soon; the real fix will be to allow us to return and query invalid ASTs.

7b55668db7618334cc40011d3c1e128524d89462 02-Dec-2009 Daniel Dunbar <daniel@zuster.org> Add ASTUnit::LoadFromCommandLine, which creates an ASTUnit out of a list of
(clang/driver) command line arguments (including the source file).
- The arguments are expected to include the source file.

- The idea is that even though this is a somewhat odd API, its the form which
many tools can most easily use (for example, by interposing with the compiler).

Also, switch index-test's -ast-from-source to use this entry point, and provide
a -arg command line argument which can be used to test that the command line
arguments are handled correctly.

Also, add an -ast-from-source option to index-test which allows index-test to
run on source files directly.

f96b524306ccfa623235d375deee79637bd38f29 28-Oct-2009 Steve Naroff <snaroff@apple.com> Remove _clang_initCXLookupHint() and _clang_getCursorWithHint(). Related to <rdar://problem/7310688>.

Localize the optimization to ResolveLocationInAST(). The last valid AST location is now stored with ASTUnit. There still isn't optimal, however it's an improvement (with a much cleaner API). Having the client manage an "hint" is error prone and complex.

I wanted to land the major changes before finishing up the optimizations.

fc0622155fa61349698a8fd0053773c37d9f7ac4 19-Oct-2009 Ted Kremenek <kremenek@apple.com> The constructor for ASTUnit now takes a DiagnosticClient*, allowing uses of ASTUnit to specify
alternate DiagnosticClients. To match this API, ASTUnit::LoadFromPCHFile() now takes a corresponding
DiagnosticClient* argument as well. The DiagnosticClient object is destroyed when the ASTUnit object
is destroyed.

The CIndex library now uses this API to create a 'IgnoreDiagnosticsClient' that simply silences
diagnostics when using the clang_createTranslationUnitFromSourceFile() function. This fixes
<rdar://problem/7312058>. This API can change in the future as we add more flexibility for clients.

its own BumpPtrAllocator to allocate ASTs.

ASTUnit::LoadFromPCHFile().

7d1d49d2971b20a97b3c2a301470b9eaaa130137 16-Oct-2009 Douglas Gregor <dgregor@apple.com> Keep track of whether declararions were loaded from a precompiled
header or not via a new "PCHLevel" field in Decl. We currently use
this information to help CIndex filter out declarations that came from
a precompiled header (rather than from an AST file). Further down the
road, it can be used to help implement multi-level precompiled
headers.
