and we now include the file name that declares the symbol with no linkage in the USR.
USRs for such symbols are generated only in restructed cases, e.g., anonymous enum declarations,
typedefs, etc.

knobs to control formatting. Eventually, I'd like to merge the
implementation of this code with the TextDiagnosticPrinter, so that
it's easy for CIndex clients to produce beautiful diagnostics like the
clang compiler does.
Use this new function to display diagnostics within c-index-test.

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.

and fix-it information, so we can see everything in one place. Along
the way, fix a few bugs with deserialization and query of diagnostics
in CIndex.

diagnostic callback mechanism, so all diagnostics now go through that
callback. Also, eliminate the displayDiagnostics flag to
clang_createIndex(), since it is no longer necessary: the client
determines whether to display diagnostics or not.
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@94714 91177308-0d34-0410-b5e6-96231b3b80d8
clients can format diagnostics as they wish rather than having to
parse standard error. All of the important parts of the front end's
diagnostics are exposed: text, severity, location, source ranges, and
fix-its. The diagnostics callback is now available with
clang_createTranslationUnitFromSource() and
clang_createTranslationUnit().
As part of this change, CXSourceLocation and CXSourceRange got one
pointer larger, since we need to hold on to the SourceManager and
LangOptions structures in the source location. This is the minimum
amount of information needed for the functions that operate on source
locations and ranges (as implemented now). Previously we held on to
the ASTContext, but the diagnostics callback can end up with source
locations when there is no ASTContext (or preprocessor).
Still to do:
- Code completion needs to support the diagnostics callback, once we
have the ability to (de-)serialize diagnostics.
- Eliminate the "displayDiagnostics" argument to createIndex; we'll
always pass diagnostics to the callback and let it deal with display.

utility of this change will be made clearer in a subsequent patch when
perform_test_load()' does more than stream the AST.

- Added more routines to manipulate/compare source locations and ranges
- Switched clang_getCursor() over to take a CXSourceLocation rather
than file/line/column.

opaque data structures accessed through the new functions
clang_getInstantiationLocation(), clang_getRangeStart(), and
clang_getRangeEnd(). The new API permits later extensions to introduce
new functions to allow CIndex clients to walk macro instantiations, if
we ever care.

CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a
given declaration cursor is also a definition. This eliminates a lot
of duplication in the cursor kinds, and maps more closely to the Clang
ASTs.
This is another API + ABI breaker with no deprecation. Yay, progress.

cursor itself. In particular, for references this returns the source
range of the reference rather than the source range of the thing it
refers to.
Switch c-index-test from clang_getDeclExtent (which will eventually be
deprecated and removed) over to clang_getCursorExtent. The source
ranges we print for references now make sense; fix up the tests
appropriately.

clang_getCursorLine(), clang_getCursorColumn(),
clang_getCursorSource(), and clang_getCursorSourceFile(). Mark those 4
functions as deprecated and stop using them ourselves.

Renamed CXSourceFileLine to CXSourceLocation and added a CXFile, to
better match Clang's SourceLocation. Teach clang_getDeclExtent to fill
in the CXFile properly.
Renamed CXSourceExtent to CXSourceRange, to better match Clang's
SourceLocation.

migrating some index-test tests over to c-index test [*] and some
grep-using tests over to FileCheck.

C++ grammatical constructs that show up in top-level (namespace-level)
declarations, member declarations, template declarations, statements,
expressions, conditions, etc. For example, we now provide a pattern
for
static_cast<type>(expr)
when we can have an expression, or
using namespace identifier;
when we can have a using directive.
Also, improves the results of code completion at the beginning of a
top-level declaration. Previously, we would see value names (function
names, global variables, etc.); now we see types, namespace names,
etc., but no values.
