2012-12-06[analyzer] Remove bindExprAndLocation, which does extra work for no gain.Jordan Rose
This feature was probably intended to improve diagnostics, but was currently only used when dumping the Environment. It shows what location a given value was loaded from, e.g. when evaluating an LValueToRValue cast. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169522 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-05Thread safety analysis: Add a new "beta" warning flag: -Wthread-safety-beta.DeLesley Hutchins
As the analysis improves, it will continue to add new warnings that are potentially disruptive to existing users. From now on, such warnings will first be introduced under the "beta" flag. Such warnings are not turned on by default; their purpose is to allow users to test their code against future planned changes, before those changes are actually made. After a suitable migration period, beta warnings will be folded into the standard -Wthread-safety. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169338 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-30Use the new LLVM_LVALUE_FUNCTION to ban two getAs() calls on rvalues.Jordan Rose
If 'x' is a temporary, x.getAs<Foo>() may not be safe if the result is supposed to persist (if its address is stored somewhere). Since getAs() can return a null value, the result is almost always stored into a variable, which of course is not safe when the original value dies. This has caused several bugs with GCC's "Temporaries May Vanish Sooner Than You Expect" optimization; in C++11 builds, at least, we'll be able to catch these problems now. I would suggest applying these to other getAs() and get*As() methods (castAs is "better" because sometimes the result is used directly, which means the temporary will still be live), but these two have both caused trouble in the analyzer in the past. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168967 91177308-0d34-0410-b5e6-96231b3b80d8
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. Fixes <rdar://problem/12552849>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168961 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
