Daniel Dunbar c13935e8be [LLVM up] Add basic -S option to clang.
- Split backend related consumer out into Backend.cpp, replaces
   LLVMCodeGenWriter.
 - Structure follows llvm-gcc to some extent.
 - Still need to implement all the options which impact code
   generation and the optimization passes which llvm-gcc uses at
   various levels.

Douglas Gregor 9a6579340f Initial step toward supporting qualification conversions (C++ 4.4).
Changes:
  - Sema::IsQualificationConversion determines whether we have a qualification
    conversion.
  - Sema::CheckSingleAssignment constraints now follows the C++ rules in C++,
    performing an implicit conversion from the right-hand side to the type of
    the left-hand side rather than checking based on the C notion of 
    "compatibility". We now rely on the implicit-conversion code to
    determine whether the conversion can happen or
    not. Sema::TryCopyInitialization has an ugly reference-related
    hack to cope with the initialization of references, for now.
  - When building DeclRefExprs, strip away the reference type, since
    there are no expressions whose type is a reference. We'll need to
    do this throughout Sema.
  - Expr::isLvalue now permits functions to be lvalues in C++ (but not
  in C).

Fix <rdar://problem/6265257> warnings for ambiguous message send swamp other warnings.

Reworked Sema::MatchTwoMethodDeclarations() to optionally match based on method size and alignment (the default in GCC). Changed Sema::LookupInstanceMethodInGlobalPool() to use this feature.

Added -Wno-struct-selector-match to driver, however didn't hook it up yet. Added a FIXME that says this.

Zhongxing Xu dab76fd822 Localize the special processing of array variable inside
GRExprEngine::VisitCast() so that other parts of the analyzer can be ignorant.
When we cast "array of type T" to "pointer to T", we get the loc::MemRegionVal
corresponding to the array variable. This is sufficient for BasicStore, but not
for RegionStore. RegionStore should get the element region for the first array
element in the cast. So next comes to the revamping of transfer functions for
different store model.

Chris Lattner 64b1f2f030 More property attribute recovery improvements. Instead of this:
crash.m:8:12: error: type name requires a specifier or qualifier
@property (readonlyx, getter=isAwesome) int _awesome;
           ^
crash.m:8:29: error: expected ';' at end of declaration list
@property (readonlyx, getter=isAwesome) int _awesome;
                            ^
crash.m:8:39: error: expected identifier or '('
@property (readonlyx, getter=isAwesome) int _awesome;
                                      ^

we now get:

crash.m:8:12: error: unknown property attribute 'readonlyx'
@property (readonlyx, getter=isAwesome) int _awesome;
           ^

Also, we can eliminate isObjCPropertyAttribute now.

Chris Lattner 43c76c38fa significantly simplify and clean up error recovery in
ParseObjCPropertyAttribute.  Before, on this code (where
a comma was forgotten):

@property (readonly getter=isAwesome) int _awesome;

we emitted:

crash.m:9:11: error: expected ')'
@property (readonly getter=isAwesome) int _awesome;
          ^
crash.m:9:37: error: type name requires a specifier or qualifier
@property (readonly getter=isAwesome) int _awesome;
                                    ^
crash.m:9:37: error: expected identifier or '('
crash.m:9:37: error: expected ';' at end of declaration list
crash.m:9:1: error: @property requires fields to be named
@property (readonly getter=isAwesome) int _awesome;
^

now we emit:

crash.m:9:21: error: expected ')'
@property (readonly getter=isAwesome) int _awesome;
                    ^
crash.m:9:11: error: to match this '('
@property (readonly getter=isAwesome) int _awesome;
          ^

Chris Lattner bb8cc18788 fix some minor error recovery bugs in ParseObjCInterfaceDeclList
where it would reject @required in non-protocols, but then go

Also, improve error recovery a bit when we see something bogus 
inside an interface.

llvm-svn: 57795
2008-10-20 04:57:38 +00:00
Chris Lattner 8ff2c6c9f0 Fix a parser bug where we let attributes interfere with our disambiguation
of whether a '(' was a grouping paren or the start of a function declarator.
This is PR2796.

Now we eat the attribute before deciding whether the paren is grouping or
not, then apply it to the resultant decl or to the first argument as needed.

One somewhat surprising aspect of this is that attributes interact with
implicit int in cases like this:

void a(x, y) // k&r style function
void b(__attribute__(()) x, y); // function with two implicit int arguments
void c(x, __attribute__(()) y); // error, can't have attr in identifier list.

Fun stuff.

Ted Kremenek 8b103c65c6 - constify some uses of MemRegion* (MemRegion should be immutable).
- Added new region "SymbolicRegion", which maps symbol values to the region domain.
- Enhanced BasicStore::getFieldLValue() to return a FieldRegion (using SymbolicRegion)
- Added some utility methods to GRState for fetch svals from the store.
- Fixed regression in CheckNSError (we weren't getting the value bound to the parameter)

Ted Kremenek 5870046c43 "Implement" GRExprEngine::VisitLValue for ObjCPropertyRefExpr. This is only a bandid; we need to properly handle properties by using locv/nonloc objects and specially handling property assignments in the transfer function for BinaryOperator.

Daniel Dunbar b9fd902fdc Change CGDebugInfo::setLocation to just ignore invalid locations. This
simplifies clients.

Also, add assert that RegionStack is empty when the CGDebugInfo is
destroyed.

Daniel Dunbar 3cd9a29c64 Fix bug in Obj-C type encoding for structures.
- Mechanism for detecting if a structure should be expanded wasn't
   reliable. Simplified by just keeping track of what we should be
   expanding.

 - This fixes a bug in using NSInvocation to invoke a method which
   returned a structure, which in used by Key Value Observing, which
   in the end, caused a miscompile in poor little Sketch.
