The integration tests require the C memory functions as the compiler may emit calls to them directly. The tests normally use the `__internal__` variant that is built for testing, but these memory functions were linked directly to preserve the entrypoint. Instead, we forward delcare the internal versions and map the entrypoints to them manually inside the integration test. This allows us to use the internal versions of these files like the rest of the test objects. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D146177
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.
