[ORC] Align ExecutorSimpleMemoryManager w/ orc_rt::SimpleNativeMemoryMap (#163693) Teach ExecutorSimpleMemoryManager to handle slab reserve/release operations, plus separate initialize/deinitialize for regions within the slab. The release operation automatically deinitializes any regions within each slab that have not already been released. EPCGenericJITLinkMemoryManager is updated to use the reserve (allocate), initialize (finalize), and relesae (deallocate) operations. This brings ExecutorSimpleMemoryManager into alignment with the orc_rt::SimpleNativeMemoryMap class, allowing SimpleNativeMemoryMap to be used as a backend for EPCGenericJITLinkMemoryManager. A future commit will introduce a new MemoryMapper class that will make SimpleNativeMemoryMap usable as a backend for MapperJITLinkMemoryManager. This work will make it easier to re-use in-tree APIs and tools with the new ORC runtime.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
