Nico Weber 3fddae75c7 Don't leak CXStrings for replacement fix-its in c-index-test.
The loop body used to contain a switch statement; it looks like r96685 replaced
that with an if/else if/else but accidentally left one of the three break
statements from the switch behind, skipping the clang_disposeString() call
for replacements (and the rest of the loop too, which apparently doesn't make
a differences for the test cases we have).

r96685: http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20100215/027754.html

This too might possibly the last leak in clang (PR19521).

Chandler Carruth b2faa59976 [leaks] Parse the schema file every time we try to verify the XML. Yes,
this is wasteful, blah blah, but this is a test utility only. It turns
out that without doing this, libxml2 will always leak a bunch of the XML
data, and that is causing failures with LSan. This is also quite a bit
simpler and I don't think it is slow enough to really be a show stopper.
If someone yells about the runtime of c-index-test, we can do other
things to try to mitigate it, but the current strategy wasn't working
well.

Alp Toker 59c6bc5882 libclang: split out the documentation comment API
It's possible that the "comment AST" may be replaced or split out in the
midterm, any anyway this makes the headers easier to read.

Developers don't currently need to include "clang-c/Documentation.h" explicitly
and there's no macro to test for availability yet.

The raw comment and brief comment accessors have been kept in Index.h though
brief support may also move here as a separate proposal.

This is not a deprecation, just a gentle separation of concerns as we look to
simplify the built-in representation of comment nodes and support external
comment processors.

Alp Toker 87d3975369 libclang: remove 'CXDiagnostic_Remark'
The change was landed without review or test cases.

It trivially broke almost any stable application checking for Severity >=
CXDiagnostic_Error or indeed any other kind of severity comparison upon
encountering a 'remark'.

Mapped to CXDiagnostic_Warning until a workable solution is proposed to the
list that preserves API stability.

(It's also not clear why the rest of r202475 wasn't simply implemented as a
modifier to the existing 'warning' level.)

Tobias Grosser 741602461d Add 'remark' diagnostic type in 'clang'
A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.

A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.

This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.

This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.

Dmitri Gribenko ea4d1c32fb libclang: report error code for bad PCH files
This commit improves libclang to report the error condition when
CXTranslationUnit can not be created because of a stale PCH file.  This allows
the caller, for example, to rebuild the PCH file and retry the request.

There two are APIs in libclang that return a CXTranslationUnit and don't
support reporting detailed errors (the only error condition is a NULL result).
For these APIs, a second, superior, version is introduced --
clang_createTranslationUnit2 and clang_parseTranslationUnit2.  These functions
return a CXTranslationUnit indirectly and also return an error code.  Old
functions are still supported and are nothing more than convenience wrappers
that ignore extended error codes.

As a cleanup, this commit also categorizes some libclang errors in the
functions I had to modify anyway.

Dmitri Gribenko f430da4de6 Add an option to allow Clang verify source files for a module only once during
the build

When Clang loads the module, it verifies the user source files that the module
was built from.  If any file was changed, the module is rebuilt.  There are two
problems with this:
1. correctness: we don't verify system files (there are too many of them, and
   stat'ing all of them would take a lot of time);
2. performance: the same module file is verified again and again during a
   single build.

This change allows the build system to optimize source file verification.  The
idea is based on the fact that while the project is being built, the source
files don't change.  This allows us to verify the module only once during a
single build session.  The build system passes a flag,
-fbuild-session-timestamp=, to inform Clang of the time when the build started.
The build system also requests to enable this feature by passing
-fmodules-validate-once-per-build-session.  If these flags are not passed, the
behavior is not changed.  When Clang verifies the module the first time, it
writes out a timestamp file.  Then, when Clang loads the module the second
time, it finds a timestamp file, so it can compare the verification timestamp
of the module with the time when the build started.  If the verification
timestamp is too old, the module is verified again, and the timestamp file is
updated.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
Now we have a list of all commands.  This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.

With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed).  Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands.  Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID.  Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.

This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state.  But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.

Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object.  This breaks binary compatibility of CXComment APIs.

Dmitri Gribenko 3292d06a1b Add a new libclang completion API to get brief documentation comment that is
attached to a declaration in the completion string.

Since extracting comments isn't free, a new code completion option is
introduced.

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

Chandler Carruth 39a3e7544a Fix a big layering violation introduced by r158771.
That commit added a new library just to hold the RawCommentList. I've
started a discussion on the commit thread about whether that is really
meritted -- it certainly doesn't seem necessary at this stage.

However, the immediate problem is that the AST library has a hard
dependency on the Comment library, but the dependencies were set up
completely backward. In addition to the layering violation, this had an
unfortunate effect if scattering the Comments library dependency
throughout the build system, but inconsistently so -- several parts of
the CMake dependencies were missing and only showed up due to transitive
deps or the fact that the target wasn't being built by tho bots.

It turns out that the Comments library can't (currently) be a well
formed layer *below* the AST library either, as it has an API that
accepts an ASTContext. That parameter is currently unused, so maybe that
was a mistake?

Anyways, it really seems like this is logically part of the AST --
that's the whole point of the ASTContext providing access to it as far
as I can tell -- so I've merged it into the AST library to solve the
immediate layering violation problems and remove some of the churn from
our library dependencies.

Argyrios Kyrtzidis 4cdfcae75d Don't map a file:line:col triplet that is inside the preamble range to
a "loaded" location of the precompiled preamble.

Instead, handle specially locations of preprocessed entities:
-When looking up for preprocessed entities, map main file locations inside the
 preamble range to a preamble loaded location.
-When getting the source range of a preprocessing cursor, map preamble loaded
 locations back to main file locations.

Chandler Carruth de81fc8557 NestedMacroInstantiations -> NestedMacroExpansions
This is switches all the interfaces points (and most of the commenst
/ local variables I saw on my way through) regarding the
NestedMacroInstantiations bit.

The libclang enums corresponding to this state were renamed, but
a legacy enum was added with the old name, and the same value to keep
existing clients working. I've added a documentation blurb for it, but
let me know if there is a canonical way to document legacy elemenst of
the libclang interface.

No functionality changed here, even in tests.

Douglas Gregor 998caead70 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.

Ted Kremenek 915542850b Change CXTranslationUnit to not directly cast to an ASTUnit*,
but to wrap both an ASTUnit and a "string pool"
that will be used for fast USR generation.

This requires a bunch of mechanical changes, as
there was a ton of code that assumed that CXTranslationUnit
and ASTUnit* were the same.

Along with this change, introduce CXStringBuf,
which provides an llvm::SmallVector<char> backing
for repeatedly generating CXStrings without a huge
amount of malloc() traffic.  This requires making
some changes to the representation of CXString
by renaming a few fields (but keeping the size
of the object the same).
