* [OPENMP] Fix crash on code emitting if errors are found.Alexey Bataev2015-03-184-1/+8
| | | | | | | Codegen for threadprivate variables (and in some other cases) may cause crash of the compiler if some diagnostic is produced later. This happens because some of the autogenerated globals are not removed from InternalVars StringMap when llvm::Module is reset. Differential Revision: http://reviews.llvm.org/D8360 llvm-svn: 232610
* MS ABI: Empty pack expansions had their mangling changed in 2013->2015David Majnemer2015-03-183-4/+15
| | | | | | | | | | We used to support the 2013 mangling and changed it to the more reasonable 2015 mangling. Let's make the mangling conditional on what version of MSVC is targeted. This fixes PR21888. llvm-svn: 232609

* [SCEV] Make isImpliedCond smarter.Sanjoy Das2015-03-183-0/+83
| | | | | | | | | | | | | | | | | | Summary: This change teaches isImpliedCond to infer things like "X sgt 0" => "X - 1 sgt -1". The `ConstantRange` class has the logic to do the heavy lifting, this change simply gets ScalarEvolution to exploit that when reasonable.

* [ConstantRange] Split makeICmpRegion in two.Sanjoy Das2015-03-186-20/+96
| | | | | | | | | | | | | | | | | | | | Summary: This change splits `makeICmpRegion` into `makeAllowedICmpRegion` and `makeSatisfyingICmpRegion` with slightly different contracts. The first one is useful for determining what values some expression //may// take, given that a certain `icmp` evaluates to true. The second one is useful for determining what values are guaranteed to //satisfy// a given `icmp`.

* DAGCombiner: fold (xor (shl 1, x), -1) -> (rotl ~1, x)David Majnemer2015-03-182-0/+38
| | | | | | | | | | Targets which provide a rotate make it possible to replace a sequence of (XOR (SHL 1, x), -1) with (ROTL ~1, x). This saves an instruction on architectures like X86 and POWER(64). Differential Revision: http://reviews.llvm.org/D8350 llvm-svn: 232572

* MS ABI: Emit HandlerMap entries for C++ catchDavid Majnemer2015-03-179-14/+93
| | | | | | | | | | | | | The HandlerMap describes, to the runtime, what sort of catches surround the try. In principle, this structure has to be emitted by the backend because only it knows the layout of the stack (the runtime needs to know where on the stack the destination of a copy lives, etc.) but there is some C++ specific information that the backend can't reason about. Stick this information in special LLVM globals with the relevant "const", "volatile", "reference" info mangled into the name. llvm-svn: 232538

* Centralize the handling of unique ids for temporary labels.Rafael Espindola2015-03-1714-87/+64
| | | | | | | | | | | | | | | | Before this patch code wanting to create temporary labels for a given entity (function, cu, exception range, etc) had to keep its own counter to have stable symbol names. createTempSymbol would still add a suffix to make sure a new symbol was always returned, but it kept a single counter. Because of that, if we were to use just createTempSymbol("cu_begin"), the label could change from cu_begin42 to cu_begin43 because some other code started using temporary labels. Simplify this by just keeping one counter per prefix and removing the various specialized counters. llvm-svn: 232535
* Remove ScriptInterpreterObject.Zachary Turner2015-03-1720-972/+1141
| | | | | | | | | | | | | | | | | | | | | | | | | This removes ScriptInterpreterObject from the codebase completely. Places that used to rely on ScriptInterpreterObject now use StructuredData::Object and its derived classes. To support this, a new type of StructuredData object is introduced, called StructuredData::Generic, which stores a void*. Internally within the python library, StructuredPythonObject subclasses this StructuredData::Generic class so that it can addref and decref the python object on construction and destruction. Additionally, all of the classes in PythonDataObjects.h such as PythonList, PythonDictionary, etc now provide a method to create an instance of the corresponding StructuredData type. For example, there is PythonDictionary::CreateStructuredDictionary. To eliminate dependencies on PythonDataObjects for external callers, all ScriptInterpreter methods now return only StructuredData classes The rest of the changes in this CL are focused on fixing up users of PythonDataObjects classes to use the new StructuredData classes. llvm-svn: 232534
