When using predicated arithmetic intrinsics, if the predicate used is all lanes active, use an unpredicated form of the instruction, additionally this allows for better use of immediate forms. This also includes a new complex isel pattern which allows matching an all active predicate when the types are different but the predicate is a superset of the type being used. For example, to allow a b8 ptrue for a b32 predicate operand. This only includes instructions where the unpredicated/predicated forms are mismatched between variants, meaning that the removal of the predicate is done during instruction selection in order to prevent spurious re-introductions of ptrue instructions.

The LLVM Compiler Infrastructure ================================ This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments. LLVM is open source software. You may freely distribute it under the terms of the license agreement found in LICENSE.txt. Please see the documentation provided in docs/ for further assistance with LLVM, and in particular docs/GettingStarted.rst for getting started with LLVM and docs/README.txt for an overview of LLVM's documentation setup. If you are writing a package for LLVM, see docs/Packaging.rst for our suggestions.
