Commit 21a4710c67a97838dd75cf60ed24da11280800f8 previously enabled LoopVectorization and SLPVectorization CodeGen options for the ELF and COFF LTO backends. Since the Mach-O LTO port did not exist at the time, it missed this configuration. This patch adds these options to the Mach-O LTO setup for consistency with the other backends. Without this, SLP and loop vectorization passes are silently skipped during Mach-O LTO for O2 and O3 builds.
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.
