Douglas Gregor f3af311382 Teach libclang to walk the base and member initializers of a
constructor, in source order. Also introduces a new reference kind for
class members, which is used here (for member initializers) and will
also be used for designated initializers and offsetof.

Ted Kremenek ff3a4ff6e9 Use FindReportInEquivalenceClass to identify all the nodes used for the trimmed graph (in BugReporter). This fixes a problem where a leak that happened to occur on both an exit() path and a non-exit() path was getting reported with the exit() path (which users don't care about).
This fixes:

<rdar://problem/8331641> leak reports should not show paths that end with exit() (but ones that don't end with exit())

Douglas Gregor ce5aa33385 Eliminate the comma locations from all of the Sema routines that deal
with comma-separated lists. We never actually used the comma

Argyrios Kyrtzidis e262a9558e Fix C++ PCH issue.
Another beating by boost in this test case: http://llvm.org/PR8117
A function specialization wasn't properly initialized if it wasn't canonical.

I wish there was a nice little test case but this was boost.

Ted Kremenek 5f256da834 Rename GRState::getSVal() -> getRawSVal() and getSimplifiedSVal() -> getSVal().
The end result is now we eagarly constant-fold symbols in the analyzer that are perfectly constrained
to be a constant value.  This allows us to recover some path-sensitivity in some cases by lowering
the required level of reasoning power needed to evaluate some expressions.

The net win from this change is that the false positive in PR 8015 is fixed, and we also
find more idempotent operations bugs.

We do, however, regress with the BugReporterVisitors, which need to be modified to understand
this constant folding (and look past it).  This causes some diagnostic regressions in plist-output.m
which will get addressed in a future patch.  plist-output.m is now marked XFAIL, while
plist-output-alternate.m now tests that the plist output is working, but with the suboptimal
diagnostics.  This second test file will eventually be removed.

Ted Kremenek b037185b52 Add 'filtered_pred_iterator' and 'filtered_succ_iterator' to CFGBlock. This allows a client
to selectively walk successors/predecessors based on commonly used filters.  For starters, add
a filter to ignore 'default:' cases for SwitchStmts when all enum values are covered by CaseStmts.

Ted Kremenek c42f345157 When building SwitchStmts in Sema, record whether all the enum values of a switch(enum) where
covered by individual case statements.  Flow-based analyses may wish to consult this information,
and recording this in the AST allows us to obviate reconstructing this information later when
we build the CFG.

Douglas Gregor a9aa29cf0b Implement libclang support for using declarations. Clang actually uses
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
  - Cursor visitation of the three AST nodes for using declarations
  - Proper source-range computation for these AST nodes
  - Using declarations have no USRs, since they don't actually declare
    any entities.

an @interface declaration.  'all_referenced_protocol_[begin,end]()' now returns the set of protocols that were referenced
in both the @interface and class extensions.  The latter is needed for semantic analysis/codegen, while the former is
needed to maintain the lexical information of the original source.

Also, added a getSourceRange() member function to NamespaceAliasDecl

Alexis Hunt 79eb5469e0 Implement C++0x user-defined string literals.
The extra data stored on user-defined literal Tokens is stored in extra
allocated memory, which is managed by the PreprocessorLexer because there isn't
a better place to put it that makes sure it gets deallocated, but only after
it's used up. My testing has shown no significant slowdown as a result, but

Douglas Gregor 99129efdd3 Improve code completion for initializer lists in constructors. Instead
of prioritizing just by initialization order, we bump the priority of
just the *next* initializer in the list, and leave everything else at
the normal priority. That way, if one intentionally skips the
initialization of a base or member (to get default initialization),
we'll still get ordered completion for the rest.

Argyrios Kyrtzidis 43b205796f Fix the memory leak of FloatingLiteral/IntegerLiteral.
For large floats/integers, APFloat/APInt will allocate memory from the heap to represent these numbers.
Unfortunately, when we use a BumpPtrAllocator to allocate IntegerLiteral/FloatingLiteral nodes the memory associated with
the APFloat/APInt values will never get freed.
I introduce the class 'APNumericStorage' which uses ASTContext's allocator for memory allocation and is used internally by FloatingLiteral/IntegerLiteral.

Peter Collingbourne 85dd0bd18d Move ExecuteCompilerInvocation to a new library FrontendTool
r110903 introduced a dependency from Frontend to every library that
declared an Action by introducing Action references that previously
resided in the driver in the file ExecuteCompilerInvocation.cpp.
This patch moves ExecuteCompilerInvocation to a new library named
FrontendTool which is intended to bear these dependencies.

Fariborz Jahanian 616d3e71c2 Handling remaining rule for synthesize bitfields in
class extensions (nonfragile-abi2).For every class @interface and class
extension @interface, if the last ivar is a bitfield of any type,
then add an implicit `char :0` ivar to the end of that interface.

Daniel Dunbar 82eb4ce476 Driver: Move Clang "triple" computation routines to method on the
ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since
the tool chain in effect is not a subclass of the Darwin one, but we were
treating it like it was.
 - This introduces some gross code duplication, but the right fix for it is to
   just move the Driver to start depending on the targets in libBasic, so I am
   not planning on fixing it immediately.

Douglas Gregor 68762e7852 Introduce a code-completion hook for the Objective-C collection
argument in a for-each statement (e.g., "for (id x in <blah>)"), which

class types in C++).

Tom Care e332c3b762 Several small changes to PseudoConstantAnalysis and the way IdempotentOperationChecker uses it.
- Psuedo -> Pseudo (doh...)
- C++ reference support
- Added pseudoconstant test case for __block vars
- Separated out static local checking from pseudoconstant analysis and generalized to non-local checking
- Added missing test cases for storage false positives

Douglas Gregor c49f5b2f11 Introduce a new code-completion point when we're parsing a
declarator. Here, we can only see a few things (e.g., cvr-qualifiers,
nested name specifiers) and we do not want to provide other non-macro
completions. Previously, we would end up in recovery mode and would
provide a large number of non-relevant completions.

John McCall 7a9aac2d9f Abstract out everything having to do with member pointers into the ABI
class;  they should just be completely opaque throughout IR gen now,
although I haven't really audited that.

Fix a bug apparently inherited from gcc-4.2 where we failed to null-check
member data pointers when performing derived-to-base or base-to-derived
conversions on them.
