If we linearize values (with an assertion tha they are disjoint) and then delinearize that linear index with th exact same basis, we know that these operations are exact inverses of each other and can be replaced with the original inputs to the linearization. Similarly, if we take a linear index, delinearize it with some bases, and then re-linearize it with that same basis (noting that the outputs of the delinearization are guaranteed to by `disjoint`, even if this is not asserted on the linearize_index operation), the re-linearization is the inverse of the delinearization, so those two operations can also be canceled out. This commit adds canonicalization patterns for these simple cancelations.
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.
