template parameters can just stay this way, since Templates aren't
DeclContexts. This gives us the nice property that everything created

Not only does this fix a memory leak, but it also makes these arrays

CallExprs as those edges help cause a n^2 explosion in the number of
destructor calls. Other consumers, such as static analysis, that
would like to have more a more complete CFG can select the inclusion
of those edges as CFG build time.
This also fixes up the two compilation users of CFGs to be tolerant of
having or not having those edges. All catch code is assumed be to
live if we didn't generate the exceptional edges for CallExprs.

There is more work to do to create descriptors for DeclContext.

- compiler-rt should be checked out into $LLVM_SRC_ROOT/projects/compiler-rt.
- On Darwin, this will automatically build the runtime libraries clang needs
into $OBJROOT/lib/clang/<version>/darwin/...
- The mechanism can easily support other platforms, and can eventually support
multiple platforms once clang has some kind of configure process (for
specifying the desired targets).
- Feedback on the approach is welcome.

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.

which are instantiations of the member functions of local
classes. These implicit instantiations have to occur at the same time
as---and in the same local instantiation scope as---the enclosing
function, since the member functions of the local class can refer to
locals within the enclosing function. This should really, really fix PR5764.
llvm-svn: 93666
distinguish between nested classes (whose member functions cannot be
parsed until the innermost non-nested class is complete) and local
classes (that are defined within a function but are not necessarily
nested). The upshot of this change, which fixes PR5764, is that the
bodies of member functions of local (non-nested) classes need to be
parsed when the local class is complete (and no later), since they may
refer to function-local static variables, typedefs, enums, etc.
llvm-svn: 93653

function template declared within a class template did not match a

previously only had a single location (the @ in @interface); now we
know where the @ is (for the start of the declaration), where the
class name is (that's the normal "location" now for diagnostics), and
where the category name is. Also, eliminated the redundant "end"
location, since ObjCContainerDecl already has better @end information.
The only XFAIL'd test is temporary; will un-XFAIL-it once I've taught
CIndex how to use the new locations.

do not look into base classes if there are any dependent base
classes. Instead, note in the lookup result that we couldn't look into
any dependent bases. Use that new result kind to detect when this case
occurs, so that we can fall back to treating the type/value/etc. as a
member of an unknown specialization.
Fixes an issue where we were resolving lookup at template definition
time and then missing an ambiguity at template instantiation time.

provide completions for @ keywords. Previously, we only provided
@-completions after an @ was actually typed, which is useful but
probably not the common case.
Also, make sure a few Objective-C 2.0 completions only show up when
Objective-C 2.0 support is enabled (the default).

that name constructors, the endless joys of out-of-line constructor
definitions, and various other corner cases that the previous hack
never imagined. Fixes PR5688 and tightens up semantic analysis for
constructor names.
Additionally, fixed a problem where we wouldn't properly enter the
declarator scope of a parenthesized declarator. We were entering the
scope, then leaving it when we saw the ")"; now, we re-enter the
declarator scope before parsing the parameter list.
Note that we are forced to perform some tentative parsing within a
class (call it C) to tell the difference between
C(int); // constructor
and
C (f)(int); // member function
which is rather unfortunate. And, although it isn't necessary for
correctness, we use the same tentative-parsing mechanism for
out-of-line constructors to improve diagnostics in icky cases like:
C::C C::f(int); // error: C::C refers to the constructor name, but
// we complain nicely and recover by treating it as
// a type.

As part of this, I had to extend PartialDiagnostic to support fix-it

name a template, when they occur in a base-specifier. This is one of
the (few) places where we know for sure that an identifier followed by
a '<' must be a template name, so we can diagnose and recover well:

initializers. This isn't actually in the C++ grammar (in any version),

were performing name lookup for template names in C/ObjC and always

they redefine is a class-name but not a typedef-name, per C++0x
[dcl.typedef]p4. The code in the test was valid C++98 and is valid
C++0x, but an unintended consequence of DR56 made it ill-formed in
C++03 (which we were luck enough to implement). Fixes PR5455.

templates. Previously, a little thinko in the code that replaced a
conversion function template with its redeclaration was causing some
very weird lookup behavior.
llvm-svn: 93166
(C++ [temp.mem]p5-6), which involves template argument deduction based
on the type named, e.g., given
struct X { template<typename T> operator T*(); } x;
when we call
x.operator int*();
we perform template argument deduction to determine that T=int. This
template argument deduction is needed for template specialization and
explicit instantiation, e.g.,
template<> X::operator float*() { /* ... */ }
and when calling or otherwise naming a conversion function (as in the
first example).
This fixes PR5742 and PR5762, although there's some remaining ugliness
that's causing out-of-line definitions of conversion function
templates to fail. I'll look into that separately.
llvm-svn: 93162
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits
ones as appropriate.
Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType,
fromQuantity(), and getQuantity() for clarity.

value bindings. Along with a small change to OSAtomicChecker, this
resolves <rdar://problem/7527292> and resolves some long-standing
issues with how values can be bound to the same physical address by
not have the same "key". This change is only a beginning; logically
RegionStore needs to better handle loads from addresses where the
stored value is larger/smaller/different type than the loaded value.
We handle these cases in an approximate fashion now (via
CastRetrievedVal and help in SimpleSValuator), but it could be made
much smarter.
llvm-svn: 93137
(1) Introduce a new 'BindingKey' class to match 'BindingValue'. This
gives us the flexibility to change the current key value from 'const
MemRegion*' to something more interesting.
(2) Rework additions/removals/lookups from the store to use new
'Remove', 'Add', 'Lookup' utility methods.
No "real" functionality change; just prep work and abstraction.
llvm-svn: 93136
incompatible with user-defined literals, specifically with the following form:
0x1p+1
The preprocessing-number token extends only as far as the 'p'; the '+' is not
included. Previously we could get away with this extension as p was an invalid
suffix, but now with user-defined literals, 'p' might well be a valid suffix
and we are forced to consider it as such.
This patch also adds a warning in non-0x C++ modes telling the user that
this extension is incompatible with C++0x that is enabled by default
(previously and with other languages, we warn only with a compliance
option such as -pedantic).
llvm-svn: 93135
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.
