zero-density.s causes spurious NFC mismatches, e.g. https://lab.llvm.org/buildbot/#/builders/92/builds/21380 This is caused by NFC script wrapping llvm-bolt binary only, so that perf2bolt invocations are replaced by `llvm-bolt --agregate-only` to achieve perf2bolt behavior. Add `show-density` to the list of flags wrapping perf2bolt calls to avoid similar issues in the future. Test Plan: ``` $ bolt/utils/nfc-check-setup.py --switch-back $ bin/llvm-lit -a tools/bolt/test/X86/zero-density.s ```
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.
