Use SymbolStringPtr for Symbol names in LinkGraph. This reduces string interning on the boundary between JITLink and ORC, and allows pointer comparisons (rather than string comparisons) between Symbol names. This should improve the performance and readability of code that bridges between JITLink and ORC (e.g. ObjectLinkingLayer and ObjectLinkingLayer::Plugins). To enable use of SymbolStringPtr a std::shared_ptr<SymbolStringPool> is added to LinkGraph and threaded through to its construction sites in LLVM and Bolt. All LinkGraphs that are to have symbol names compared by pointer equality must point to the same SymbolStringPool instance, which in ORC sessions should be the pool attached to the ExecutionSession. --------- Co-authored-by: Lang Hames <lhames@gmail.com>
The LLVM Compiler Infrastructure
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.
