* [ORC] Errorize the ORC APIs.Lang Hames2017-07-0715-29/+28
| | | | | | | | This patch updates the ORC layers and utilities to return and propagate llvm::Errors where appropriate. This is necessary to allow ORC to safely handle error cases in cross-process and remote JITing. llvm-svn: 307350
* [Orc] Remove the memory manager argument to addModule, and de-templatize theLang Hames2017-07-046-13/+14
| | | | | | | | | | | | | | | | symbol resolver argument. De-templatizing the symbol resolver is part of the ongoing simplification of ORC layer API. Removing the memory management argument (and delegating construction of memory managers for RTDyldObjectLinkingLayer to a functor passed in to the constructor) allows us to build JITs whose base object layers need not be compatible with RTDyldObjectLinkingLayer's memory mangement scheme. For example, a 'remote object layer' that sends fully relocatable objects directly to the remote does not need a memory management scheme at all (that will be handled by the remote). llvm-svn: 307058

* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-2/+2
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* Update Kaleidoscope tutorial and improve Windows supportMehdi Amini2017-02-118-27/+90
| | | | | | | | | | | | | | | Many quoted code blocks were not in sync with the actual toy.cpp files. Improve tutorial text slightly in several places. Added some step descriptions crucial to avoid crashes (like InitializeNativeTarget* calls). Solve/workaround problems with Windows (JIT'ed method not found, using custom and standard library functions from host process).

* [CMake] Fix pthread handling for out-of-tree buildsEric Fiselier2017-02-101-1/+1
| | | | | | | | | | | | | | | LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects to correctly link the threading library when needed. Unfortunately `PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed and therefore can't be used when configuring out-of-tree builds. This causes such builds to fail since `pthread` isn't being correctly linked. This patch attempts to fix that problem by renaming and exporting `LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB` because It seemed likely to cause collisions with downstream users of `LLVMConfig.cmake`. llvm-svn: 294690

* ExceptionDemo: remove some undefined behaviourSaleem Abdulrasool2016-11-201-14/+17
| | | | | | | | The casting based reading of the LSDA could attempt to read unsuitably aligned data. Avoid that case by explicitly using a memcpy. A similar approach is used in libc++abi to address the same UB. llvm-svn: 287479
* ExceptionDemo: prefer headers over redeclarationsSaleem Abdulrasool2016-11-201-63/+9
| | | | | | | | | | | Rather than redeclaring the interfaces for exceptions, prefer using the `unwind.h` header. This is vended by at least gcc and clang, and can also be found by an external unwinding library (e.g. libunwind). Doing this simplifies the example to the exception handling itself. Minor tweaks are the result of _Unwind_Context_t not being defined, which is just a typedef for struct _Unwind_Context *. NFC. llvm-svn: 287478

* [ORC] Refactor the ORC RPC utilities to add some new features.Lang Hames2016-11-112-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (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. llvm-svn: 286620

* [BuildingAJIT] Use the remote target triple to construct the TargetMachine inLang Hames2016-10-191-1/+2
| | | | | | | | | | Chapter 5. Chapter 5 demonstrates remote JITing: code is executed on the remote, not the machine running the REPL, so it's the remote's triple (and TargetMachine) that we need. llvm-svn: 284657

* [Kaleidoscope] Make Chapter 2 use llvm::make_unique, rather than a helper.Lang Hames2016-09-192-22/+15

* [ExecutionEngine][MCJIT][Orc] Replace RuntimeDyld::SymbolInfo with JITSymbol.Lang Hames2016-08-016-35/+33
| | | | | | | | | | | | | | | | This patch replaces RuntimeDyld::SymbolInfo with JITSymbol: A symbol class that is capable of lazy materialization (i.e. the symbol definition needn't be emitted until the address is requested). This can be used to support common and weak symbols in the JIT (though this is not implemented in this patch). For consistency, RuntimeDyld::SymbolResolver is renamed to JITSymbolResolver. For space efficiency a new class, JITEvaluatedSymbol, is introduced that behaves like the old RuntimeDyld::SymbolInfo - i.e. it is just a pair of an address and symbol flags. Instances of JITEvaluatedSymbol can be used in symbol-tables to avoid paying the space cost of the materializer. llvm-svn: 277386

| | | | | | | | | | | | This new chapter describes compiling LLVM IR to object files. The new chaper is chapter 8, so later chapters have been renumbered. Since this brings us to 10 chapters total, I've also needed to rename the other chapters to use two digit numbering. Differential Revision: http://reviews.llvm.org/D18070 llvm-svn: 274441
* [MCJIT] Update MCJIT and get the fibonacci example working again.Lang Hames2016-06-112-0/+3
| | | | | | | | | | MCJIT will now set the DataLayout on a module when it is added to the JIT, rather than waiting until it is codegen'd, and the runFunction method will finalize the module containing the function to be run before running it. The fibonacci example has been updated to include and link against MCJIT. llvm-svn: 272455
* [Orc] Add conversion to/from RuntimeDyld::SymbolInfo for JITSymbol.Lang Hames2016-05-316-8/+8
| | | | | | | | | | This tidies up some code that was manually constructing RuntimeDyld::SymbolInfo instances from JITSymbols. It will save more mess in the future when JITSymbol::getAddress is extended to return an Expected<TargetAddress> rather than just a TargetAddress, since we'll be able to embed the error checking in the conversion. llvm-svn: 271350

| | | | | | | | | | | | This chapter demonstrates lazily JITing from ASTs with the expressions being executed on a remote machine via a TCP connection. It needs some polish, but is substantially complete. Currently x86-64 SysV ABI (Darwin and Linux) only, but other architectures can be supported by changing the server code to use alternative ABI support classes from llvm/include/llvm/ExecutionEngine/Orc/OrcABISupport.h. llvm-svn: 271193

* [Kaleidoscope][BuildingAJIT] Fix a bug in the symbol resolver in Chapter2.Lang Hames2016-05-261-1/+1
| | | | | | | | | | | Symbol resolution should be done on the top layer of the stack unless there's a good reason to do otherwise. In this case it would have worked because OptimizeLayer::addModuleSet eagerly passes all modules down to the CompileLayer, meaning that searches in CompileLayer will find the definitions. In later chapters where the top layer's addModuleSet isn't a pass-through, this would break. llvm-svn: 270899
