…ition. Renames the SimpleSymbolTable addSymbolsUnique method to addUnique. The new class name (from c727cd9a4b2) already implies that we're adding symbols. This commit also relaxes the error condition for addUnique: Rather than rejecting any duplicate symbols, it only rejects symbols that were previously added with a different address. This makes it safe to add the same symbol(s) multiple time, as long as all definitions point to the same address. The intent of this is to allow ORC runtime components to unconditionally add their interfaces to symbols, even if that interface might have been added previously.
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.
