symbols.

Evan Cheng a7bb55ebb6 Fix a dagga combiner bug: avoid creating illegal constant. 
Is this really a winning transformation?

Ted Kremenek fe12f88924 RegionStore: 
-refactor logic for retrieving bindings from VarDecls into
 RegionStoreManager::RetrieveVar()
- improve RegionStoreManager::CastRetrievedVal() and SimpleSValuate::EvalCastNL
  to better handle casts of values of the same canonical type as well as
  casts of LocAsInteger values.

Argyrios Kyrtzidis 05ac8276cf Change the semantics for Entity. 
Entity can now refer to declarations that are not visible outside the translation unit.
It is a wrapper of a pointer union, it's either a Decl* for declarations that don't
"cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl.

Included is a test case for handling fields across translation units.

Argyrios Kyrtzidis a8cf0beeef Implement the virtual getNextRedeclaration() for ObjCMethodDecl. 
If it's in an ObjCContainerDecl, its "redeclaration" is the method definition in the corresponding ObjCImplDecl.
If it's in an ObjCImplDecl, its "redeclaration" is the method in the interface.

llvm-svn: 76512
 2009-07-21 00:06:36 +00:00
Argyrios Kyrtzidis 60e9b7cf58 Add an assertion for the return value of Decl::getNextRedeclaration().

Argyrios Kyrtzidis 1559d67b7a Remove the ObjCCategoryImpls vector from Sema class.

 2009-07-21 00:06:20 +00:00

llvm-svn: 76509
 2009-07-21 00:06:04 +00:00
Argyrios Kyrtzidis 6d9fab7619 - Introduce ASTContext::getObjCImplementation() and ASTContext::setObjCImplementation() which use a DenseMap to associate 
an interface/category with its implementation (if one exists).

- Introduce ObjCInterfaceDecl::get/setImplementation() and ObjCCategoryDecl::get/setImplementation() that use the above methods.

- Add a compiler error for when a category is reimplemented.

llvm-svn: 76505
 2009-07-20 23:54:43 +00:00
Dan Gohman 00c1aaec5a Remove the code that tried to evaluate whether (A pred B) is known 
by determining if (B pred (B-A)) is known, as it doesn't handle
overflow correctly.

Dale Johannesen a2d2adfa4e Make sure a global matching asm 'i' constraint gets its 
flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)
gcc.apple/asm-block-25.c (test passed before by
accident, but generated code was wrong)

llvm-svn: 76503
 2009-07-20 23:39:13 +00:00
Dale Johannesen ade297d496 Move stripping of bitcasts in inline asm arguments 
to a place where it affects everything.  Occurs
only on calls AFAIK.

llvm-svn: 76502

Ted Kremenek 834e2f69da Enhanced IsReinterpreted() (RegionStore.cpp) to reason about higher-order 
pointers.

Enhanced RegionStoreManager::Retrieve() to handle automatic casts when the
loaded value is different from the requested value. This should be refined over
time, but essentially we should always symbolicate locations as locations, and
convert them to non-locations on demand.

These changes now cause 'misc-ps.m' to pass again.

Douglas Gregor d12df6b160 Reuse VarDecl::Init to store the default argument of a ParmVarDecl, 
reducing the size of ParmVarDecl by one pointer. Also means that we'll 
properly (de-)serialize default arguments in C++ PCH files.
