2009-10-16Fix static analyzer crash due to recently add symbolic-value constant ↵Ted Kremenek
folding. The issue was falsely converting the constant value of the LHS of a '<<'/'>>' operation to the same APSInt value of the RHS. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84269 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Keep track of whether declararions were loaded from a precompiledDouglas Gregor
header or not via a new "PCHLevel" field in Decl. We currently use this information to help CIndex filter out declarations that came from a precompiled header (rather than from an AST file). Further down the road, it can be used to help implement multi-level precompiled headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84267 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-16Implement derived-to-base AST/code gen. There is aFariborz Jahanian

2009-10-16Add support for a chain of stat caches in the FileManager, rather thanDouglas Gregor
only supporting a single stat cache. The immediate benefit of this change is that we can now generate a PCH/AST file when including another PCH file; in the future, the chain of stat caches will likely be useful with multiple levels of PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84263 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Apply heuristics to cut back on number of candidateFariborz Jahanian
sets of builtin operators. Currently, it is applied to '++' and '->*' operators. I need to apply it to others as well. Also, heuristics need be applied to BuiltinCandidateTypeSet::AddPointerWithMoreQualifiedTypeVariants.

2009-10-15Diagnose explicit instantiations of function templates and memberDouglas Gregor
functions/static data members of class template specializations that do not have definitions. This is the latter part of [temp.explicit]p4; the former part still needs more testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84182 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-15Per an astute observation from Zhongxing Xu, remove a "special case" logic inTed Kremenek
RegionStoreManager::Retrieve() that was intended to handle conflated uses of pointers as integers. It turns out this isn't needed, and resulted in inconsistent behavior when creating symbolic values on the following test case in 'tests/Analysis/misc-ps.m': typedef struct _BStruct { void *grue; } BStruct; void testB_aux(void *ptr); void testB(BStruct *b) { { int *__gruep__ = ((int *)&((b)->grue)); int __gruev__ = *__gruep__; testB_aux(__gruep__); } { int *__gruep__ = ((int *)&((b)->grue)); int __gruev__ = *__gruep__; if (~0 != __gruev__) {} } } When the code was analyzed with '-arch x86_64', the value assigned to '__gruev__' be would be a symbolic integer, but for '-arch i386' the value assigned to '__gruev__' would be a symbolic region (a blob of memory). With this change the value created is always a symbolic integer. Since the code being removed was added to support analysis of code calling OSAtomicCompareAndSwapXXX(), I also modified 'test/Analysis/NSString.m' to analyze the code in both '-arch i386' and '-arch x86_64', and also added some complementary test cases to test the presence of leaks when using OSAtomicCompareAndSwap32Barrier()/OSAtomicCompareAndSwap64Barrier() instead of just their absence. This code change reveals that previously both RegionStore and BasicStore were handling these cases wrong, and would never cause the analyzer to emit a leak in these cases (false negatives). Now RegionStore gets it right, but BasicStore still gets it wrong (and hence it has been disabled temporarily for this test case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84163 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-14fix some cfstring related issues: Chris Lattner
1) -fwritable-string does affect the non-utf16 version of cfstrings just not the utf16 ones. 2) utf16 strings should always be marked constant, as the __TEXT segment is readonly. 3) The name of the global doesn't matter, remove it from TargetInfo. 4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

2009-10-13Improve diagnostics when the parser encounters a declarator with anDouglas Gregor
unknown type name, e.g., foo::bar x; when "bar" does not refer to a type in "foo". With this change, the parser now calls into the action to perform diagnostics and can try to recover by substituting in an appropriate type. For example, this allows us to easily diagnose some missing "typename" specifiers, which we now do: test/SemaCXX/unknown-type-name.cpp:29:1: error: missing 'typename' prior to dependent type name 'A<T>::type' A<T>::type A<T>::f() { return type(); } ^~~~~~~~~~ typename Fixes PR3990. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@84053 91177308-0d34-0410-b5e6-96231b3b80d8
