2012-01-24The following patch adds __attribute__((no_address_safety_analysis)) which ↵Kostya Serebryany
will allow to disable address safety analysis (such as e.g. AddressSanitizer or SAFECode) for a specific function. When building with AddressSanitizer, add AddressSafety function attribute to every generated function except for those that have __attribute__((no_address_safety_analysis)). With this patch we will be able to 1. disable AddressSanitizer for a particular function 2. disable AddressSanitizer-hostile optimizations (such as some cases of load widening) when AddressSanitizer is on. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148842 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-16Some improvements to the handling of C11 atomic types:David Chisnall
- Add atomic-to/from-nonatomic cast types - Emit atomic operations for arithmetic on atomic types - Emit non-atomic stores for initialisation of atomic types, but atomic stores and loads for every other store / load - Add a __atomic_init() intrinsic which does a non-atomic store to an _Atomic() type. This is needed for the corresponding C11 stdatomic.h function. - Enables the relevant __has_feature() checks. The feature isn't 100% complete yet, but it's done enough that we want people testing it. Still to do: - Make the arithmetic operations on atomic types (e.g. Atomic(int) foo = 1; foo++;) use the correct LLVM intrinsic if one exists, not a loop with a cmpxchg. - Add a signal fence builtin - Properly set the fenv state in atomic operations on floating point values - Correctly handle things like _Atomic(_Complex double) which are too large for an atomic cmpxchg on some platforms (this requires working out what 'correctly' means in this context) - Fix the many remaining corner cases git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148242 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-14De-virtualize getPreviousDecl() and getMostRecentDecl() when we knowDouglas Gregor
we have a redeclarable type, and only use the new virtual versions (getPreviousDeclImpl() and getMostRecentDeclImpl()) when we don't have that type information. This keeps us from penalizing users with strict type information (and is the moral equivalent of a "final" method). Plus, settle on the names getPreviousDecl() and getMostRecentDecl() throughout. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148187 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-14constexpr irgen: Add irgen support for APValue::Struct, APValue::Union,Richard Smith
APValue::Array and APValue::MemberPointer. All APValue values can now be emitted as constants. Add new CGCXXABI entry point for emitting an APValue MemberPointer. The other entrypoints dealing with constant member pointers are no longer necessary and will be removed in a later change. Switch codegen from using EvaluateAsRValue/EvaluateAsLValue to VarDecl::evaluateValue. This performs caching and deals with the nasty cases in C++11 where a non-const object's initializer can refer indirectly to previously-initialized fields within the same object. Building the intermediate APValue object incurs a measurable performance hit on pathological testcases with huge initializer lists, so we continue to build IR directly from the Expr nodes for array and record types outside of C++11. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148178 91177308-0d34-0410-b5e6-96231b3b80d8
