a VarRegion. Fixes PR15358 and <rdar://problem/13295437>. Along the way, shorten path diagnostics that say "Variable 'x'" to just be "'x'". By the context, it is obvious that we have a variable, and so this just consumes text space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176115 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-26Use the most recent decl in getExplicitVisibility.Rafael Espindola
Now that implicitly hidden template arguments can make an instantiation hidden, it is important to look at more than just the canonical decl of the argument in order to see if an attribute is available in a more recent decl. This has the disadvantage of exposing when getExplicitVisibility is called, but lets us handle cases like template <typename T> struct __attribute__((visibility("default"))) barT { static void zed() {} }; class foo; class __attribute__((visibility("default"))) foo; template struct barT<foo>; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176112 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-26Be more careful in applying pragma weak. Fixes pr14974.Rafael Espindola
GCC applies a pragma weak to a decl if it matches the mangled name. We used to apply if it matched the plain name. This patch is a compromise: we apply the pragma only if it matches the name and the decl has C language linkage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176110 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-26Only keep empty lines in unwrapped lines if they preceed a line comment.Daniel Jasper
Empty lines followed by line comments are often used to highlight the comment. Empty lines somewhere else are usually left over from manual or automatic formatting and should probably be removed. Before (clang-format would keep): S s = { a, b }; After: S s = { a, b }; git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176086 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-26Only break string literals as a last resort.Daniel Jasper
We might want to move towards doing this if the formatting can be significantly improved, but we need to carefully evaluate the different situations first.

2013-02-26Unify clang/llvm attributes for asan/tsan/msan (Clang part)Kostya Serebryany
These are two related changes (one in llvm, one in clang). LLVM: - rename address_safety => sanitize_address (the enum value is the same, so we preserve binary compatibility with old bitcode) - rename thread_safety => sanitize_thread - rename no_uninitialized_checks -> sanitize_memory CLANG: - add __attribute__((no_sanitize_address)) as a synonym for __attribute__((no_address_safety_analysis)) - add __attribute__((no_sanitize_thread)) - add __attribute__((no_sanitize_memory)) for S in address thread memory If -fsanitize=S is present and __attribute__((no_sanitize_S)) is not set llvm attribute sanitize_S git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176076 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-26[analyzer] Don't look through casts when creating pointer temporaries.Jordan Rose
Normally, we need to look through derived-to-base casts when creating temporary object regions (added in r175854). However, if the temporary is a pointer (rather than a struct/class instance), we need to /preserve/ the base casts that have been applied. This also ensures that we really do create a new temporary region when we need to: MaterializeTemporaryExpr and lvalue CXXDefaultArgExprs. Fixes PR15342, although the test case doesn't include the crash because I couldn't isolate it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176069 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-26[analyzer] StackAddrEscapeChecker: strip qualifiers from temporary types.Jordan Rose
With the new support for trivial copy constructors, we are not always consistent about whether a CXXTempObjectRegion gets reused or created from scratch, which affects whether qualifiers are preserved. However, we probably don't care anyway. This also switches to using the current PrintingPolicy for the type, which means C++ types don't get a spurious 'struct' prefix anymore. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176068 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25[analyzer] Restrict ObjC type inference to methods that have related result ↵Anna Zaks
type. This addresses a case when we inline a wrong method due to incorrect dynamic type inference. Specifically, when user code contains a method from init family, which creates an instance of another class. Use hasRelatedResultType() to find out if our inference rules should be triggered. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176054 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-25[analyzer] Recover all PreStmtPurgeDeadSymbols nodes with a single successor ↵Ted Kremenek
or predecessor. These nodes are never consulted by any analyzer client code, so they are used only for machinery for removing dead bindings. Once successor nodes are generated they can be safely removed. This greatly reduces the amount of nodes that are generated in some case, lowering the memory regression when analyzing Sema.cpp introduced by r176010 from 14% to 2%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176050 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25[analyzer] Handle reference parameters with default values.Jordan Rose
r175026 added support for default values, but didn't take reference parameters into account, which expect the default argument to be an lvalue. Use createTemporaryRegionIfNeeded if we can evaluate the default expr as an rvalue but the expected result is an lvalue. Fixes the most recent report of PR12915. The original report predates default argument support, so that can't be it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176042 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-25[analyzer] Base regions may be invalid when layered on symbolic regions.Jordan Rose
While RegionStore checks to make sure casts on TypedValueRegions are valid, it does not do the same for SymbolicRegions, which do not have perfect type info anyway. Additionally, MemRegion::getAsOffset does not take a ProgramState, so it can't use dynamic type info to determine a better type for the regions. (This could also be dangerous if the type of a super-region changes!) Account for this by checking that a base object region is valid on top of a symbolic region, and falling back to "symbolic offset" mode if not. Fixes PR15345. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176034 91177308-0d34-0410-b5e6-96231b3b80d8
