* Sema: Caught exception objects should be unqualifiedDavid Majnemer2015-03-031-1/+1
| | | | | | | | The exception object should be unqualified. Using a qualified exception object results in the wrong copy constructor getting called when the catch handler executes. llvm-svn: 231054
* Sema: Properly initialize the thrown exception objectDavid Majnemer2015-03-032-21/+19
| | | | | | | We would create the exception object with the wrong qualifiers, ensuring that the wrong copy constructor would get called. llvm-svn: 231049

* CodeGen: Fix passing of classes with only one AVX vector member in AVX registersBenjamin Kramer2015-03-021-15/+4
| | | | | | | | | | | | | | isSingleElementStruct was a bit too tight in its definition of struct so we got a mismatch between classify() and the actual code generation. To make matters worse the code in GetByteVectorType still defaulted to <2 x double> if it encountered a type it didn't know, making this a silent miscompilation (PR22753). Completely remove the "preferred type" stuff from GetByteVectorType and make it fail an assertion if someone tries to use it with a type not suitable for a vector register. llvm-svn: 230971

* Rework our handling of key functions. We used to track a complete list of allRichard Smith2015-02-286-71/+29
| | | | | | | | | | | | | | dynamic classes in the translation unit and check whether each one's key function is defined when we got to the end of the TU (and when we got to the end of each module). This is really terrible for modules performance, since it causes unnecessary deserialization of every dynamic class in every compilation. We now use a much simpler (and, in a modules build, vastly more efficient) system: when we see an out-of-line definition of a virtual function, we check whether that function was in fact its class's key function. (If so, we need to emit the vtable.) llvm-svn: 230830
* DebugInfo: hoist definition into global context when neededSaleem Abdulrasool2015-02-281-3/+12
| | | | | | | | | | | | When generating debug info for a static inline member which is initialized for the DLLExport storage class, hoist the definition into a non-composite type context. Otherwise, we would trigger an assertion when generating the DIE for the associated global value as the debug context has a type association. This addresses PR22669. Thanks to David Blakie for help in coming up with a solution to this! llvm-svn: 230816

* [OPENMP] Codegen for "#pragma omp atomic write"Alexey Bataev2015-02-273-187/+407
| | | | | | | | | | For global reg lvalue - use regular store through global register. For simple lvalue - use simple atomic store. For bitfields, vector element, extended vector elements - the original value of the whole storage (for vector elements) or of some aligned value (for bitfields) is atomically read, the part of this value for the given lvalue is modified and then use atomic compare-and-exchange operation to try to atomically write modified value (if it was not modified). Also, changes in this patch fix the bug for '#pragma omp atomic read' applied to extended vector elements. Differential Revision: http://reviews.llvm.org/D7369 llvm-svn: 230736

* Don't crash on leaving nested __finally blocks through an EH edge.Nico Weber2015-02-261-19/+12
| | | | | | | | | | | | | | | The __finally emission block tries to be clever by removing unused continuation edges if there's an unconditional jump out of the __finally block. With exception edges, the EH continuation edge isn't always unused though and we'd crash in a few places. Just don't be clever. That makes the IR for __finally blocks a bit longer in some cases (hence small and behavior-preserving changes to existing tests), but it makes no difference in general and it fixes the last crash from PR22553. http://reviews.llvm.org/D7918 llvm-svn: 230697

* Win64: Silently ignore __stdcall, __fastcall, and __thiscallReid Kleckner2015-02-262-6/+21
| | | | | | | | | | MSVC doesn't warn on this. Users are expected to apply the WINAPI macro to functions passed by pointer to the Win32 API, and this macro expands to __stdcall. This means we end up with a lot of useless noisy warnings about ignored calling conventions when compiling code with clang for Win64. llvm-svn: 230668
* Add support for generating MIPS legacy NaNPetar Jovanovic2015-02-262-4/+21
| | | | | | | | | | | Currently, the NaN values emitted for MIPS architectures do not cover non-IEEE754-2008 compliant case. This change fixes the issue. Patch by Vladimir Radosavljevic. Differential Revision: http://reviews.llvm.org/D7882 llvm-svn: 230653

* [msan] Change track-origins default mode from 1 to 2.Evgeniy Stepanov2015-02-261-1/+1
| | | | | | | | | | | Change -fsanitize-memory-track-origins to be equivalent to -fsanitize-memory-track-origins=2. Track-origins=2 provides a lot more detailed reports at the cost of some additional slowdown (ranging from none to, sometimes, 3x; ~3% average on SPEC2006). llvm-svn: 230644

* clang-format: Allow breaking after "else if(" as a last resort.Daniel Jasper2015-02-261-2/+3

| | | | | | | | | | | | lib/headers paths There is no supported toolchain which provides headers / libs / object files specific to the mips32r[3|5] and mips64r[3|5] ISA. So select "r2" specific folders when they are available. http://reviews.llvm.org/D7879 llvm-svn: 230611
* CGDebugInfo: Use DIImportedEntity default constructor, NFCDuncan P. N. Exon Smith2015-02-261-2/+2
| | | | | | | | | | | | | | | | Use the newly minted `DIImportedEntity` default constructor (r230609) rather than explicitly specifying `nullptr`. The latter will become ambiguous when the new debug info hierarchy is committed, since we'll have both of the following: explicit DIImportedEntity(const MDNode *); DIImportedEntity(const MDImportedEntity *); (Currently we just have the former.) A default constructor is just as clear. llvm-svn: 230610
* Update assumption in template diffing about integer template arguments.Richard Trieu2015-02-261-6/+14
| | | | | | | | | | Fix for PR22017. Integer template arguments are automatically bit extended to the size of the integer type. In template diffing, evaluated expressions were not having their results extending, leading to comparing two APSInt's with different widths. Apply the proper bit extending when evaluating template arguments. This mainly affected bool template arguments. llvm-svn: 230603
* Sema: __assume with side effects shouldn't result in invalid AST nodesDavid Majnemer2015-02-261-1/+1
| | | | | | | | We'd diagnose an __assume expression which contained a function call. This would result in us wrongly returning ExprError, causing mysterious failures later on. llvm-svn: 230597

* Add -fuse-line-directive flag to control usage of #line with -EReid Kleckner2015-02-264-23/+25
| | | | | | | | | | | | | | | | | | Currently -fms-extensions controls this behavior, which doesn't make much sense. It means we can't identify what is and isn't a system header when compiling our own preprocessed output, because #line doesn't represent this information. If someone is feeding Clang's preprocessed output to another compiler, they can use this flag. Fixes PR20553. Reviewers: rsmith Differential Revision: http://reviews.llvm.org/D5217 llvm-svn: 230587
* Remove some unused includes of llvm/IR headers from parts of Clang that reallyRichard Smith2015-02-262-2/+0

* Improvement on sized deallocation from r230160:Larisse Voufo2015-02-252-14/+92
| | | | | | Do not declare sized deallocation functions dependently on whether it is found in global scope. Instead, enforce the branching in emitted code by (1) declaring the functions extern_weak and (2) emitting sized delete expressions as a branching between both forms delete. llvm-svn: 230580
