2016-11-12[ORC] Add a WrappedHandlerReturn type to map handler return types onto errorLang Hames
return types. This class allows user provided handlers to return either error-wrapped types or plain types. In the latter case, the plain type is wrapped with a success value of Error or Expected<T> type to fit it into the rest of the serialization machinery. This patch allows us to remove the RPC unit-test workaround added in r286646. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@286701 91177308-0d34-0410-b5e6-96231b3b80d8

2016-11-11[Support] Introduce llvm::formatv() function.Zachary Turner
This introduces a new type-safe general purpose formatting library. It provides compile-time type safety, does not require a format specifier (since the type is deduced), and provides mechanisms for extending the format capability to user defined types, and overriding the formatting behavior for existing types. This patch additionally adds documentation for the API to the LLVM programmer's manual.

2016-11-11MachineScheduler/ScheduleDAG: Add support to skipping a node.Matthias Braun
The DAG mutators in the scheduler cannot really remove DAG nodes as additional anlysis information such as ScheduleDAGToplogicalSort are already computed at this point and rely on a fixed number of DAG nodes.

2016-11-11Make the FunctionComparator of the MergeFunctions pass a stand-alone utility.Erik Eckstein
This is pure refactoring. NFC. This change moves the FunctionComparator (together with the GlobalNumberState utility) in to a separate file so that it can be used by other passes. For example, the SwiftMergeFunctions pass in the Swift compiler: https://github.com/apple/swift/blob/master/lib/LLVMPasses/LLVMMergeFunctions.cpp Details of the change: *) The big part is just moving code out of MergeFunctions.cpp into FunctionComparator.h/cpp *) Make FunctionComparator member functions protected (instead of private) so that a derived comparator class can use them. Following refactoring helps to share code between the base FunctionComparator class and a derived class: *) Add a beginCompare() function *) Move some basic function property comparisons into a separate function compareSignature() *) Do the GEP comparison inside cmpOperations() which now has a new needToCmpOperands reference parameter https://reviews.llvm.org/D25385 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@286632 91177308-0d34-0410-b5e6-96231b3b80d8

2016-11-11[ORC] Refactor the ORC RPC utilities to add some new features.Lang Hames
(1) Add support for function key negotiation. The previous version of the RPC required both sides to maintain the same enumeration for functions in the API. This means that any version skew between the client and server would result in communication failure. With this version of the patch functions (and serializable types) are defined with string names, and the derived function signature strings are used to negotiate the actual function keys (which are used for efficient call serialization). This allows clients to connect to any server that supports a superset of the API (based on the function signatures it supports). (2) Add a callAsync primitive. The callAsync primitive can be used to install a return value handler that will run as soon as the RPC function's return value is sent back from the remote. (3) Launch policies for RPC function handlers. The new addHandler method, which installs handlers for RPC functions, takes two arguments: (1) the handler itself, and (2) an optional "launch policy". When the RPC function is called, the launch policy (if present) is invoked to actually launch the handler. This allows the handler to be spawned on a background thread, or added to a work list. If no launch policy is used, the handler is run on the server thread itself. This should only be used for short-running handlers, or entirely synchronous RPC APIs. (4) Zero cost cross type serialization. You can now define serialization from any type to a different "wire" type. For example, this allows you to call an RPC function that's defined to take a std::string while passing a StringRef argument. If a serializer from StringRef to std::string has been defined for the channel type this will be used to serialize the argument without having to construct a std::string instance. This allows buffer reference types to be used as arguments to RPC calls without requiring a copy of the buffer to be made. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@286620 91177308-0d34-0410-b5e6-96231b3b80d8

2016-11-11Clean up DWARFFormValue by reducing duplicated code and removing ↵Greg Clayton
DWARFFormValue::getFixedFormSizes() In preparation for a follow on patch that improves DWARF parsing speed, clean up DWARFFormValue so that we have can get the fixed byte size of a form value given a DWARFUnit or given the version, address byte size and dwarf32/64. This patch cleans up code so that everyone is using one of the new DWARFFormValue functions: static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, const DWARFUnit *U = nullptr); static Optional<uint8_t> DWARFFormValue::getFixedByteSize(dwarf::Form Form, uint16_t Version, uint8_t AddrSize, bool Dwarf32); This patch changes DWARFFormValue::skipValue() to rely on the output of DWARFFormValue::getFixedByteSize(...) instead of duplicating the code in each function. This will reduce the number of changes we need to make to DWARF to fewer places in DWARFFormValue when we add support for new form. This patch also starts to support DWARF64 so that we can get correct byte sizes for forms that vary according the DWARF 32/64. To reduce the code duplication a new FormSizeHelper pure virtual class was created that can be created as a FormSizeHelperDWARFUnit when you have a DWARFUnit, or FormSizeHelperManual where you manually specify the DWARF version, address byte size and DWARF32/DWARF64. There is now a single implementation of a function that gets the fixed byte size (instead of two where one took a DWARFUnit and one took the DWARF version, address byte size and DWARFFormat enum) and one function to skip the form values. https://reviews.llvm.org/D26526 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@286597 91177308-0d34-0410-b5e6-96231b3b80d8

2016-11-11Split Bitcode/ReaderWriter.h into separate reader and writer headersTeresa Johnson
Summary: Split ReaderWriter.h which contains the APIs into both the BitReader and BitWriter libraries into BitcodeReader.h and BitcodeWriter.h. This is to address Chandler's concern about sharing the same API header between multiple libraries (BitReader and BitWriter). That concern is why we create a single bitcode library in our downstream build of clang, which led to r286297 being reverted as it added a dependency that created a cycle only when there is a single bitcode library (not two as in upstream).

The NamedRegionTimer initializer without a group name puts the Timer into the "Misc" group and is (nearly) unused. Remove it.
