llvm.ctlz.<type> intrinsic has additional i1 argument is_zero_undef, it tells whether zero as the first argument produces a defined result. MIPS clz instruction returns 32 for zero input. G_CTLZ is generated from llvm.ctlz.<type> (<type> <src>, i1 false) intrinsics, clang generates these intrinsics from __builtin_clz and __builtin_clzll. G_CTLZ_ZERO_UNDEF can also be generated from llvm.ctlz with true as second argument. It is also traditionally part of and many algorithms that are now predicated on avoiding zero-value inputs. Add narrow scalar for G_CTLZ (algorithm uses G_CTLZ_ZERO_UNDEF). Lower G_CTLZ_ZERO_UNDEF and select G_CTLZ for MIPS32. Differential Revision: https://reviews.llvm.org/D73214 |

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.
