Revert "[VectorUtils] Trivially vectorize ldexp, [l]lround (#145545)" This reverts commit 13366759c3b9db9366659d870cc73c938422b020. This broke various LLVM testsuite buildbots for AArch64 SVE, but the problem got masked because relevant buildbots were already failing due to other breakage. It has broken llvm-test-suite test: gfortran-regression-compile-regression__vect__pr106253_f.test https://lab.llvm.org/buildbot/#/builders/4/builds/8164 https://lab.llvm.org/buildbot/#/builders/17/builds/9858 https://lab.llvm.org/buildbot/#/builders/41/builds/8067 https://lab.llvm.org/buildbot/#/builders/143/builds/9607
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
