[InstrProf][compiler-rt] Fix counter section alignment issue I recently discovered that `.profraw` headers are expected to be 8 byte aligned. https://github.com/llvm/llvm-project/blob/643ba926c1f618401c86dc37e659df795db2e1a0/llvm/lib/ProfileData/InstrProfReader.cpp#L503-L506 When function entry coverage mode is used, function counters are single bytes, so it is likely that the size of the counters section is not 8 byte aligned. We can add padding after the counters section to guarantee this. Reviewed By: kyulee, gulfem Differential Revision: https://reviews.llvm.org/D152479
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.
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.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
