[ValueTracking] Extend LHS/RHS with matching operand to work without constants. Previously we only handled the `L0 == R0` case if both `L1` and `R1` where constant. We can get more out of the analysis using general constant ranges instead. For example, `X u> Y` implies `X != 0`. In general, any strict comparison on `X` implies that `X` is not equal to the boundary value for the sign and constant ranges with/without sign bits can be useful in deducing implications. Closes #85557
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
