2011-09-13Rename InterFace -> Interface, no functionality change.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139620 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13A strong property of block type has "copy" setter semantics, not "retain".John McCall
This is consistent with the behavior of assigning into a __strong l-value, and it's also necessary for ensuring that the ivar doesn't end up a dangling reference. We decided not to change the behavior of "retain" properties, but just to make them warnings/errors when of block type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139619 91177308-0d34-0410-b5e6-96231b3b80d8

-Allow cursor visitation of an attribute using its source range -Add C++ 'final' and 'override' attributes as cursor kinds -Simplify the logic that marks 'final' and 'override' attributes as tokens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139609 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13In Microsoft mode, downgrade "goto into protected scope" from error to ↵Francois Pichet
warning if we are jumping over a variable initialization via a goto. This fixes a few errors when parsing MFC code with clang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139595 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Switch -Wreturn-type to completely rely on the CFG model of no-return.Chandler Carruth
This deletes a bunch of crufty code, and allows more logic sharing between the analyzer and the warnings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139594 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Add a bit to the CFGBlock to track when it contains a no-returnChandler Carruth
CFGElement. This will allow greatly simplifying the logic in -Wreturn-type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139593 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Consolidate the logic for building a no-return CFG block into a singleChandler Carruth
location with a single comment rather than scattering it in three places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139592 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Don't use native atomics on ivars whose size is not a power of two,John McCall
even on architectures that support unaligned access (which is the only way this is otherwise legal, given that ivars apparently do not honor alignment attributes). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139590 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13This test seems pretty low-value.John McCall
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139589 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Enhance the CFG construction to detect no-return destructors forChandler Carruth
temporary objects and local variables. When detected, these split the block, marking the new one as having only the exit block as a successor. This prevents a large number of false positives in warnings sensitive to no-return constructs such as -Wreturn-type, and fixes the remainder of PR10063 along with several variations of this bug that had not been reported. The test cases are extended across the board to cover these patterns. This also checks in a stress test for these types of CFGs. The stress test declares some 32k variables, a mixture of no-return and normal destructors. Previously, this resulted in roughly 2500 CFG blocks, but didn't model any of the no-return destructors. With this patch, it results in over 33k blocks, many of them now unreachable. The nice thing about how the analyzer is set up? This causes *no* regression in performance of building the CFG. It actually in some cases makes it faster, as best I can benchmark. The analysis for -Wreturn-type (and any other that cares about no-return code paths) is technically slower now as it has to look at many more candidate blocks, but it computes the correct answer. I have more test cases to follow, I think they all work now. Also I have further work that should dramatically simplify analyses in the presence of no-return. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139586 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139585 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Always emit bitfield properties using expression behavior, even if they'reJohn McCall
atomic. This is probably something we should warn about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139584 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13Unify the decision of how to emit property getters and setters into aJohn McCall
single code path. Use atomic loads and stores where necessary. Load and store anything of the appropriate size and alignment with primitive operations instead of going through the call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139580 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-13When compiling a module on-demand, re-use the diagnostics clientDouglas Gregor
already provided. This required a little bit of clean-up in the way that VerifyDiagnosticsClient managed ownership of its underlying "primary" client, because now it will no longer always take ownership. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139570 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-12When an import statement fails to find a module in the module cache,Douglas Gregor
but there is a corresponding umbrella header in a framework, build the module on-the-fly so it can be immediately loaded at the import statement. This is very much proof-of-concept code, with details to be fleshed out over time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139558 91177308-0d34-0410-b5e6-96231b3b80d8
