2012-03-21[analyzer] Malloc: Utter the name of the leaked variable.Anna Zaks
Specifically, we use the last store of the leaked symbol in the leak diagnostic. (No support for struct fields since the malloc checker doesn't track those yet.) + Infrastructure to track the regions used in store evaluations. This approach is more precise than iterating the store to obtain the region bound to the symbol, which is used in RetainCount checker. The region corresponds to what is uttered in the code in the last store and we do not rely on the store implementation to support this functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153212 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21Duplicated code is bad. At least make it consistent.Bob Wilson
The getARMTargetCPU and getLLVMArchSuffixForARM functions exist in both Toolchain.cpp and Tools.cpp. This stuff needs a thorough overhaul. In the meantime, this patch at least makes them consistent. One version had been converted to use StringSwitch, and the other version had new Cortex M-series processors added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153202 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21For Darwin, do not let -mcpu override the -arch option. <rdar://11059238>Bob Wilson
On Darwin the architecture and the corresponding Mach-O slice is typically specified with -arch. If not, it defaults to the current host architecture. Do not use -mcpu to override the -arch value. This is only an issue when people need to use specialized code for a non-default CPU (hopefully guarded by run-time checks to detect the current processor). The -mcpu option is still used for the -target-cpu option to clang, but this patch causes it to not be used to set the architecture in the target triple. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153197 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-21For the annals of subtle but terrible bugs: fix a longstanding bugJohn McCall
in vtable layout where virtual methods inherited from virtual bases could be assigned the same vcall adjustment slot if they shared a name and parameter signature but differed in their cv-qualification. The code was already trying to handle this case, but unfortunately used the ordinary type qualifiers (which are always empty here) instead of the method qualifiers. This seems like something that the API should discourage, but I don't know how to carry that principle out in this instance. Eliminate this function's need for an ASTContext while we're at it. This bug affects the ABI, and fixing it brings us into accord with the Itanium ABI (and GCC's implementation of it), but, obviously, technically breaks full compatibility with previous releases of Clang. Just letting you know. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153168 91177308-0d34-0410-b5e6-96231b3b80d8

the realloc call and the null check, so we get nicer path notes. Fixes a regression introduced by the diagnostic pruning added in r152361. This is accomplished by calling markInteresting /during/ path diagnostic generation, and as such relies on deterministic ordering of BugReporterVisitors -- namely, that BugReporterVisitors are run in /reverse/ order from how they are added. (Right now that's a consequence of storing visitors in an ImmutableList, where new items are added to the front.) It's a little hacky, but it works for now. I think this is the best we can do without storing the relation between the old and new symbols, and that would be a hit whether or not there ends up being an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153010 91177308-0d34-0410-b5e6-96231b3b80d8
