2012-09-26[analyzer] Add experimental ObjC invalidation method checker.Anna Zaks
This checker is annotation driven. It checks that the annotated invalidation method accesses all ivars of the enclosing objects that are objects of type, which in turn contains an invalidation method. This is driven by __attribute((annotation("objc_instance_variable_invalidator")). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164716 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-26Fix an edge case of mangling involving the combination of a lambda and typeid.Eli Friedman
typeid (and a couple other non-standard places where we can transform an unevaluated expression into an evaluated expression) is special because it introduces an an expression evaluation context, which conflicts with the mechanism to compute the current lambda mangling context. PR12123. I would appreciate if someone would double-check that we get the mangling correct with this patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164658 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-26Fix the AST representation for non-type template arguments to encodeEli Friedman
enough information so we can mangle them correctly in cases involving dependent parameter types. (This specifically impacts cases involving null pointers and cases involving parameters of reference type.) Fix the mangler to use this information instead of trying to scavenge it out of the parameter declaration. <rdar://problem/12296776>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164656 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25Rename CanFitInto64Bits to alwaysFitsInto64Bits per discussion on IRC.Jordan Rose
This makes the behavior clearer concerning literals with the maximum number of digits. For a 32-bit example, 4,000,000,000 is a valid uint32_t, but 5,000,000,000 is not, so we'd have to count 10-digit decimal numbers as "unsafe" (meaning we have to check for overflow when parsing them, just as we would for numbers with 11 digits or higher). This is the same, only with 64 bits to play with. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164639 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25Optimize NumericLiteralParser::GetIntegerValue().Dmitri Gribenko
It does a conservative estimate on the size of numbers that can fit into uint64_t. This bound is improved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164624 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-25Reapply "[analyzer] Remove constraints on dead symbols as part of ↵Jordan Rose
removeDeadBindings." Previously, we'd just keep constraints around forever, which means we'd never be able to merge paths that differed only in constraints on dead symbols. Because we now allow constraints on symbolic expressions, not just single symbols, this requires changing SymExpr::symbol_iterator to include intermediate symbol nodes in its traversal, not just the SymbolData leaf nodes. This depends on the previous commit to be correct. Originally applied in r163444, reverted in r164275, now being re-applied. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164622 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-25[analyzer] Calculate liveness for symbolic exprs as well as atomic symbols.Jordan Rose
No tests, but this allows the optimization of removing dead constraints. We can then add tests that we don't do this prematurely. <rdar://problem/12333297> Note: the added FIXME to investigate SymbolRegionValue liveness is tracked by <rdar://problem/12368183>. This patch does not change the existing behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164621 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-25Under certain terrible circumstances (<rdar://problem/10805775>),Douglas Gregor
top-level frameworks can actually be symlinked over to embedded frameworks, and accessed via the top-level framework's headers. In this case, we need to determine that the framework was *actually* an embedded framework, so we can load the appropriate top-level module. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164620 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25Examine the last, not the first, instruction from the MC matcher.Bob Wilson
If an MS-style inline asm is matched to multiple instructions, e.g., with a a WAIT-prefix, then we need to examine the operands of the last instruction instruction, not the prefix instruction. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164608 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-25Introduce builtin macros to determine whether we're building aDouglas Gregor
specific module (__building_module(modulename)) and to get the name of the current module as an identifier (__MODULE__). Used to help headers behave differently when they're being included as part of building a module. Oh, the irony. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164605 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-25When performing a ::delete of an object with a virtual destructor,John McCall
be sure to delete the complete object pointer, not the original pointer. This is necessary if the base being deleted is at a non-zero offset in the complete object. This is only required for objects with virtual destructors because deleting an object via a base-class subobject when the base does not have a virtual destructor is undefined behavior. Noticed while reviewing the last four years of cxx-abi-dev activity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164597 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25During jump-scope checking, build an ExprWithCleanups immediatelyJohn McCall
into the enclosing scope; this is a more accurate model but is (I believe) unnecessary in my test case due to other flaws. However, one of those flaws is now intentional: blocks which appear in return statements can be trivially observed to not extend in lifetime past the return, and so we can allow a jump past them. Do the necessary magic in IR-generation to make this work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164589 91177308-0d34-0410-b5e6-96231b3b80d8
