For handling intrinsics, our approach is not simply to match them one-to-one with instructions. Instead, we lower some intrinsics to common nodes and then perform matching. The advantage of this approach is that it allows us to fully utilize the passes available at the common layer for optimizing purposes. We perform error checks on the immediate operand of all intrinsics, rather than waiting until the end to throw exceptions.

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.
