How do I compile with LLVM?

Build LLVM and Clang:

1. cd llvm-project.
2. mkdir build (in-tree build is not supported)
3. cd build.
4. cmake -DLLVM_ENABLE_PROJECTS=clang -G “Unix Makefiles” ../llvm.
5. make.
6. This builds both LLVM and Clang for debug mode.
7. Note: For subsequent Clang development, you can just run make clang.

What does LLVM stand for?

Low Level Virtual Machine
The name LLVM was originally an initialism for Low Level Virtual Machine. LLVM was originally developed as a research infrastructure to investigate dynamic compilation techniques for static and dynamic programming languages.

Is clang better than Msvc?

The c++ code compiled by clang runs a lot faster than the same code compiled by MSVC. And I checked the ASM code, found out that clang automatically uses SIMD instructions for speed purposes. So I rewrite the main calculation part by using AVX Intrinsics code.

Is GCC faster than MSVC?

GCC is a fine compiler, and can produce code that has pretty much the same performance, if not better, than MSVC. It is missing some low-level Windows-specific features though.

How do I install LLVM on my Mac?

This is most useful if you want a no-fuss drop-in replacement for Apple GCC. To install this, sudo to root, then untar in /. This installs tools in /usr/local/bin , which work on either ppc and intel macs.
