When we check for similarity, right now there is no order to how it is checked, except for via the suffix tree ordering. We can reduce how much structural analysis we perform by checking the the regions in decreasing size. In doing so, we know that if two large sections match, each of their contained regions also match. This allows us to skip the structural checking for each smaller section. IT does require that we use the large regions as a "bridge" to create the canonical mapping between the two regions. This reduces compile time significantly for some benchmarks. It will not perform as well for programs with many small items. Recommit fixes the IRSimilarity tests. Recommit of: |

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.
Getting the Source Code and Building LLVM
Consult the Getting Started with LLVM page for information on building and running LLVM.

Getting in touch
Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
