2012-11-29Keep track of modules that have failed to build. If we encounter anDouglas Gregor
import of that module elsewhere, don't try to build the module again: it won't work, and the experience is quite dreadful. We track this information somewhat globally, shared among all of the related CompilerInvocations used to build modules on-the-fly, so that a particular Clang instance will only try to build a given module once.

Status: usable, but may produce false positives w/o proper blacklisting. 2) use-after-return sanitizer Status: implemented, but heavily understed.

Original commit message: Remove redundant code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168900 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-29Merge function types in C.Rafael Espindola
Among other differences, GCC accepts typedef int IA[]; typedef int A10[10]; static A10 *f(void); static IA *f(void); void g(void) { (void)sizeof(*f()); } but clang used to reject it with: invalid application of 'sizeof' to an incomplete type 'IA' (aka 'int []') The intention of c99's 6.2.7 seems to be that we should use the composite type and accept as gcc does. Doing the type merging required some extra fixes: * Use the type from the function type in initializations, even if an parameter is available. * Fix the merging of the noreturn attribute in function types. * Make CodeGen handle the fact that an parameter type can be different from the corresponding type in the function type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168895 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-29The declaration of a special member can require overload resolution to beRichard Smith
performed, to determine whether that special member is deleted or constexpr. That overload resolution process can in turn trigger the instantiation of a template, which can do anything, including triggering the declaration of that very same special member function. When this happens, do not try to recursively declare the special member -- that's impossible. Instead, only try to realise the truth. There is no special member. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168847 91177308-0d34-0410-b5e6-96231b3b80d8

the original parameter or return type. Since we do not accurately represent the data fields of a union, we should not directly load or store a union type. As an exmple, if we have i8,i8, i32, i32 as one field type and i32,i32 as another field type, the first field type will be chosen to represent the union. If we load with the union's type, the 3rd byte and the 4th byte will be skipped. rdar://12723368 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168820 91177308-0d34-0410-b5e6-96231b3b80d8

objc_loadWeak. This retains and autorelease the weakly-refereced object. This hidden autorelease sometimes makes __weak variable alive even after the weak reference is erased, because the object is still referenced by an autorelease pool.
