The motivation for this change is explained in https://github.com/llvm/llvm-project/issues/72354. Before this change, we could not tell between signed/unsigned minimum/maximum and NaN treatment for floating point values. The mapping of old reduction operations to the new ones is as follows: * `min` --> `minsi` for ints, `minf` for floats * `max` --> `maxsi` for ints, `maxf` for floats New reduction kinds not represented in the old enum: `minui`, `maxui`, `minimumf`, `maximumf`. As a next step, I would like to have a common definition of combining kinds used by the `vector` and `gpu` dialects. Separately, the GPU to SPIR-V lowering does not yet properly handle zero and NaN values -- the behavior of floating point min/max group reductions is not specified by the SPIR-V spec, see https://github.com/llvm/llvm-project/issues/73459.

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, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
