2012-10-30[analyzer] Fix a bug in REGISTER_MAP_WITH_PROGRAMSTATEAnna Zaks
The ImmutableMap should not be the key into the GDM map as there could be several entries with the same map type. Thanks, Jordan. This complicates the usage of the macro a bit. When we want to retrieve the whole map, we need to use another name. Currently, I set it to be Name ## Ty as in "type of the map we are storing in the ProgramState". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@167000 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-30[analyzer] New checker for missing super calls in UIViewController subclasses.Jordan Rose
This is a syntactic checker aimed at helping iOS programmers correctly subclass and override the methods of UIViewController. While this should eventually be covered by the 'objc_requires_super' attribute, this checker can be used with the existing iOS SDKs without any header changes. This new checker is currently named 'alpha.osx.cocoa.MissingSuperCall'. Patch by Julian Mayer! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166993 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-29Partially roll back r166898; it exposed a bug in the standard.Richard Smith
The problem is as follows: C++11 has contexts which are not potentially-evaluated, and yet in which we are required or encouraged to perform constant evaluation. In such contexts, we are not permitted to implicitly define special member functions for literal types, therefore we cannot evalaute those constant expressions. Punt on this in one more context for now by skipping checking constexpr variable initializers if they occur in dependent contexts. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166956 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-29-Warc-repeated-use-of-weak: allow single reads in loops from local variables.Jordan Rose
Previously, the warning would erroneously fire on this: for (Test *a in someArray) use(a.weakProp); ...because it looks like the same property is being accessed over and over. However, clearly this is not the case. We now ignore loops like this for local variables, but continue to warn if the base object is a parameter, global variable, or instance variable, on the assumption that these are not repeatedly usually assigned to within loops. Additionally, do-while loops where the condition is 'false' are not really loops at all; usually they're just used for semicolon-swallowing macros or using "break" like "goto". <rdar://problem/12578785&12578849> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166942 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-29[analyzer] New option to not suppress null return paths if an argument is null.Jordan Rose
Our one basic suppression heuristic is to assume that functions do not usually return NULL. However, when one of the arguments is NULL it is suddenly much more likely that NULL is a valid return value. In this case, we don't suppress the report here, but we do attach /another/ visitor to go find out if this NULL argument also comes from an inlined function's error path. This new behavior, controlled by the 'avoid-suppressing-null-argument-paths' analyzer-config option, is turned off by default. Turning it on produced two false positives and no new true positives when running over LLVM/Clang. This is one of the possible refinements to our suppression heuristics. <rdar://problem/12350829> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166941 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-29[analyzer] Use the CallEnter node to get a value for tracked null arguments.Jordan Rose
Additionally, don't collect PostStore nodes -- they are often used in path diagnostics. Previously, we tried to track null arguments in the same way as any other null values, but in many cases the necessary nodes had already been collected (a memory optimization in ExplodedGraph). Now, we fall back to using the value of the argument at the time of the call, which may not always match the actual contents of the region, but often will. This is a precursor to improving our suppression heuristic. <rdar://problem/12350829> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166940 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-29This patch adds alignment information for long double to the 64-bit PowerPCBill Schmidt
ELF subtarget. The existing description string is moved from PPC64TargetInfo to its DarwinTargetInfo subclass, to avoid any changes to the Darwin ABI. PPC64TargetInfo now has two possible description strings: one for FreeBSD, which requires 8-byte alignment, and a default string that requires 16-byte alignment. I've added a test for PPC64 Linux to verify the 16-byte alignment. If somebody wants to add a separate test for FreeBSD, that would be great. Note that there is a companion patch to update the alignment information in LLVM, which I am committing now as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166927 91177308-0d34-0410-b5e6-96231b3b80d8
