When initialized, the index of the ElementRegion was unsigned. But the index
value of the ArraySubscriptExpr is signed. This inconsistency caused the value
of the array element retrieved to be UnknownVal despite it was initialized to
symbolic.
This is only a hack. Real fix of this problem is required.

- Creator function pointers are saved in ManagerRegistry.
- The Register* class is used to notify ManagerRegistry new module is
available.
- AnalysisManager queries ManagerRegistry for configurable module. Then it
passes them to GRExprEngine, in turn to GRStateManager.

id<P0>
The intended overloading behavior of these entities isn't entirely
clear, and GCC seems to have some strange limitations (e.g., the
inability to overload on id<P0> vs. id<P1>). We'll want to revisit
these semantics and determine just how Objective-C++ overloading
should really work.

converting a pointer to one Objective-C interface into a pointer to another
Objective-C interface, and conversions with 'id'. The semantics seems
to match GCC, although they seem somewhat ad hoc.
Fixed a few cases where we assumed the C++ definition of isObjectType,
but were getting the C definition, causing failures in trouble with
conversions to void pointers.

-Change Parser::ParseCXXScopeSpecifier to MaybeParseCXXScopeSpecifier
-Remove Parser::isTokenCXXScopeSpecifier and fold it into MaybeParseCXXScopeSpecifier
-Rename Parser::TryAnnotateScopeToken to TryAnnotateCXXScopeToken and only allow it to be called when in C++

Implemented anonymous category (also know as continuation class)
used to override main class's property attribute. This is work in
propgress.

One design problem that is emerging is the signed-ness problem during static
analysis. Many unsigned value have to be converted into signed value because
it partipates in operations with signed values.
On the other hand, we cannot blindly make all values occuring in static analysis
signed, because we do have cases where unsignedness is required, for example,
integer overflow detection.

instead of converting them to strings first. This also fixes a
bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.
llvm-svn: 59948
uses of getName() with uses of getDeclName(). This upgrades a bunch of
diags to take DeclNames instead of std::strings.
This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.
llvm-svn: 59947
assert if the name is not an identifier. Update callers to do the right
thing and avoid this method in unsafe cases. This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.
llvm-svn: 59936
a new NamedDecl::getAsString() method.
Change uses of Selector::getName() to just pass in a Selector
where possible (e.g. to diagnostics) instead of going through
an std::string.
This also adds new formatters for objcinstance and objcclass
as described in the dox.

with implicit quotes around them. This has a bunch of follow-on
effects and requires tweaking to a whole lot of code. This causes
a regression in two tests (xfailed) by causing it to emit things like:
Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')
instead of:
Line 10: duplicate interface declaration for category 'MyClass1(Category1)'
I will fix this in a follow-up commit.
As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency. This is good, but I was planning to do this
as an independent patch. There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

diags over to use this. QualTypes implicitly print single quotes around
them for uniformity and future extension.
Doing this requires a little function pointer dance to prevent libbasic
from depending on libast.

clang executable (when built with gcc 4.2 on the mac) from 14519740 to
14495028 bytes. This shrinks individual object files as well: SemaChecking
from 23580->22248, SemaDeclObjc from 61368->57376, SemaExpr from
115628->110516, as well as several others.

would not eat the "-1" in "0x0p-1", but LiteralSupport would accept
it when extensions are on. This caused strangeness and failures
when hexfloats were properly treated as an extension (not error)
in LiteralSupport.

its call sites. This makes it more explicit when the hasError flag is
getting set and removes a confusing difference in behavior between
PP.Diag and Diag in this code.

(and carefully calculated) effect of allowing the compiler to reason
about the aliasing properties of DiagnosticBuilder object better,
allowing the whole thing to be promoted to registers instead of
resulting in a ton of stack traffic.
While I'm not very concerned about the performance of the Diag() method
invocations, I *am* more concerned about their code size and impact on the
non-diagnostic code. This patch shrinks the clang executable (in
release-asserts mode with gcc-4.2) from 14523980 to 14519816 bytes. This
isn't much, but it shrinks the lexer from 38192 to 37776, PPDirectives.o
from 31116 to 28868 bytes, etc.

and one for pulling structured information out of the diagnostic when
formatting and presenting it.
There is no functionality change with this patch.
