2011-11-09Fix an issue that Duncan discovered on a specific (no longer current)Chandler Carruth
version of Ubuntu. It has a very broken multiarch configuration, and so we need special logic to handle it correctly. Fixing and testing this uncovered a few other trivial issues with the logic that are fixed as well. I added tests to cover this as it is hard to notice if you install recent versions of the OS. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144165 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-09Emit the copy and dipose helpers for ARC __strongJohn McCall
block-typed __block variables using objc_retainBlock and objc_dispose. Previously we were using _Block_object_assign and _Block_object_destroy with BLOCK_BYREF_CALLER, which causes the runtime to completely ignore the retain and release. In most cases this doesn't cause catastrophe because the retain/release are balanced and because the block in the variable was copied upon assignment there. However, the stack copy of the variable will be released when it goes out of scope, which is a problem if that value was released due to an assignment to the heap copy. Similarly, a leak can occur if the variable is assigned after the copy to the heap. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144162 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-09[PCH] Fix reading from PCH of diagnostic pragmas.Argyrios Kyrtzidis
In certain cases ASTReader would call the normal DiagnosticsEngine API to initialize the state of diagnostic pragmas but DiagnosticsEngine would try to compare source locations leading to crash because the main FileID was not yet initialized. Yet another case of the ASTReader trying to use the normal APIs and inadvertently breaking invariants. Fix this by having the ASTReader set up the internal state directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144153 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08[analyzer] Remove redundant check from DivZeroCheckerAnna Zaks
Analysis by Ted: " if (stateZero && !stateNotZero) { is checking to see if: (A) "it is possible for the value to be zero" (stateZero) AND (B) "it is not possible for the value to be non-zero" (!stateNotZero) That said, the only way for both B to be true AND A to be false is if the path is completely infeasible by the time we reach the divide-by-zero check. For the most part (all cases?), such cases should automatically get pruned out at branches (i.e., an infeasible path gets dropped), which is the case in our tests. So the question is whether or not such an infeasible path might not get dropped earlier? I can't envision any right now. Indeed, the rest of the checker assumes that if the bug condition didn't fire then 'stateNotZero' is non-NULL: C.addTransition(stateNotZero); " git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144114 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08Add a default system include of '/include'. This isn't particularlyChandler Carruth
useful when using Clang as a system-compiler, but its harmless. When using Clang as a cross-compiler, this can be very handy as quite a few toolchains ship their libc headers here rather than under '/usr/include'. For reference, this is the beginning of my work to also make the Clang driver more suitable as a cross-compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144089 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08Check pointer types for arguments of Neon load/store macros. rdar://9958031Bob Wilson
The Neon load/store intrinsics need to be implemented as macros to avoid hiding alignment attributes on the pointer arguments, and the macros can only evaluate those pointer arguments once (in case they have side effects), so it has been hard to get the right type checking for those pointers. I tried various alternatives in the arm_neon.h header, but it's much more straightforward to just check directly in Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144075 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-08Fix a cluster of related issues involving value-dependence and constantRichard Smith
expression evaluation: - When folding a non-value-dependent expression, we may try to use the initializer of a value-dependent variable. If that happens, give up. - In C++98, actually check that a const, non-volatile DeclRefExpr inside an ICE is of integral or enumeration type (a reference isn't OK!) - In C++11, DeclRefExprs for objects of const literal type initialized with value-dependent expressions are themselves value-dependent. - So are references initialized with value-dependent expressions (though this case is missing from the C++11 standard, along with many others). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144056 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-08Clean up type flags for overloaded Neon builtins. No functional change.Bob Wilson
This patch just adds a simple NeonTypeFlags class to replace the various hardcoded constants that had been used until now. Unfortunately I couldn't figure out a good way to avoid duplicating that class between clang and TableGen, but since it's small and rarely changes, that's not so bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144054 91177308-0d34-0410-b5e6-96231b3b80d8
