2013-02-08Fix test failure by making sure this file isn't identical to any other fileNick Lewycky
included in the same test. Clang gets confused about whether it's already built a module for this file, when running on a content-addressible filesystem. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174694 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-08CMake: Optionally allow running the Clang unit tests in standalone builds.Jordan Rose
The reason this is not enabled by default is because there is no way for Clang to guarantee that the LLVM unit testing infrastruture has been built. However, if it /has/ been built, there's no reason why the standalone Clang build can't use it! This should have no effect on existing builds -- in a combined build the value of the CLANG_INCLUDE_TESTS option defaults to the LLVM equivalent, and in a standalone build it defaults to off. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174691 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-08Fix stack overflow and improve performance when a module contains manyRichard Smith
overloads of a name by claiming that there are no lookup results for that name in modules while loading the names from the module. Lookups in deserialization really don't want to find names which they themselves are in the process of introducing. This also has the pleasant side-effect of automatically caching PCH lookups which found no names. The runtime here is still quadratic in the number of overloads, but the constant is lower. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174685 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07[analyzer] Report bugs when freeing memory with offset pointerAnna Zaks
The malloc checker will now catch the case when a previously malloc'ed region is freed, but the pointer passed to free does not point to the start of the allocated memory. For example: int *p1 = malloc(sizeof(int)); p1++; free(p1); // warn From the "memory.LeakPtrValChanged enhancement to unix.Malloc" entry in the list of potential checkers.

2013-02-07[analyzer] Add pointer escape type param to checkPointerEscape callbackAnna Zaks
The checkPointerEscape callback previously did not specify how a pointer escaped. This change includes an enum which describes the different ways a pointer may escape. This enum is passed to the checkPointerEscape callback when a pointer escapes. If the escape is due to a function call, the call is passed. This changes previous behavior where the call is passed as NULL if the escape was due to indirectly invalidating the region the pointer referenced.

2013-02-07[analyzer] Don't reinitialize static globals more than once along a pathAnna Zaks
This patch makes sure that we do not reinitialize static globals when the function is called more than once along a path. The motivation is code with initialization patterns that rely on 2 static variables, where one of them has an initializer while the other does not. Currently, we reset the static variables with initializers on every visit to the function along a path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174676 91177308-0d34-0410-b5e6-96231b3b80d8

ContainerUSR is not really a CXString, but it should own the underlying memory buffer. Thus, it is better to change the type to std::string.

2013-02-07Fix handling of module imports adding names to a DeclContext after qualifiedRichard Smith
name lookup has been performed in that context (this probably only happens in C++). 1) Whenever we add names to a context, set a flag on it, and if we perform lookup and discover that the context has had a lookup table built but has the flag set, update all entries in the lookup table with additional names from the external source. 2) When marking a DeclContext as having external visible decls, mark the context in which lookup is performed, not the one we are adding. These won't be the same if we're adding another copy of a pre-existing namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174577 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07Simplify FindExternalVisibleDeclsByName by making it return a bool indicatingRichard Smith
if it found any decls, rather than returning a list of found decls. This removes a returning-ArrayRef-to-deleted-storage bug from MultiplexExternalSemaSource (in code not exercised by any of the clang binaries), reduces the work required in the found-no-decls case with PCH, and importantly removes the need for DeclContext::lookup to be reentrant. No functionality change intended! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174576 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-07Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor
modules. The use of this flag enables a modules optimization where a given set of macros can be labeled as "ignored" by the modules system.
