This patch adds a new recipe to combine multiple recipes into an 'expression' recipe, which should be considered as single entity for cost-modeling and transforms. The recipe needs to be 'decomposed', i.e. replaced by its individual recipes before execute. This subsumes VPExtendedReductionRecipe and VPMulAccumulateReductionRecipe and should make it easier to extend to include more types of bundled patterns, like e.g. extends folded into loads or various arithmetic instructions, if supported by the target. It allows avoiding re-creating the original recipes when converting to concrete recipes, together with removing the need to record various information. The current version of the patch still retains the original printing matching VPExtendedReductionRecipe and VPMulAccumulateReductionRecipe, but this specialized print could be replaced with printing the bundled recipes directly.

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.
