LLVM Snapshot Build Status: 20251027, V22.0.0, 6cb942c

Stay informed about the build status of the LLVM snapshot for 20251027, version v22.0.0, commit 6cb942c, built with Flang. This article provides an overview of the build monitoring process, build matrix, and status updates for various Fedora architectures.

Introduction to LLVM Snapshot Monitoring

This article focuses on providing updates for the LLVM (v22.0.0, commit llvm/llvm-project@6cb942c) snapshot built with Flang for 20251027. We are closely monitoring these builds on the Fedora infrastructure to ensure stability and identify any potential issues. This comprehensive approach helps maintain the integrity of the LLVM project across different platforms.

The monitoring process involves continuous checks and updates, reflecting the build progress at regular intervals. The Continuous Integration (CI) system automatically updates this article with the latest status, making it a central hub for tracking build outcomes. This proactive monitoring is crucial for early detection of build failures, which allows the team to address issues promptly and efficiently. Our goal is to deliver a reliable and robust LLVM snapshot by keeping a close eye on the build process and promptly resolving any emerging problems. Regular updates are provided to ensure that the community remains informed about the ongoing status of the builds.

Understanding the Build Monitoring Process

Our build monitoring process is designed to provide detailed insights into the status of each build. Here's a breakdown of how it works:

1. Log Analysis: When a build fails on a specific platform, such as fedora-rawhide-x86_64, our system analyzes the build log to determine the cause of the failure. The possible causes include: srpm_build_issue, copr_timeout, network_issue, dependency_issue, test, downstream_patch_application, rpm__installed_but_unpackaged_files_found, rpm__directory_not_found, rpm__file_not_found, cmake_error, and unknown. By categorizing the failure, we can quickly identify patterns and address the root causes.
2. Cause Identification: For each identified cause, we list the affected packages and relevant excerpts from the log. This level of detail helps developers pinpoint the exact location of the issue, streamlining the debugging process. Understanding the specifics of each failure is critical for developing targeted solutions and preventing future occurrences.
3. Labeling Issues: To enhance organization and tracking, we use labels to categorize issues. For instance, if a unit test in upstream LLVM is broken, we add labels like error/test and build_failed_on/fedora-rawhide-x86_64. These labels provide a clear and concise overview of the issue, making it easier for contributors to understand the problem and its impact. Effective labeling ensures that the right people are notified and that issues are prioritized appropriately.
4. Automated Updates: If a build is manually restarted in Copr and succeeds, the system automatically removes the corresponding labels. This automation reduces manual effort and ensures that the issue tracker remains current and accurate. The automated removal of labels helps maintain a clean and efficient workflow, allowing the team to focus on resolving actual issues rather than managing outdated information.

This structured approach to build monitoring ensures that we maintain a high standard of quality for LLVM snapshots. Continuous monitoring, detailed analysis, and automated updates are key components of our strategy to deliver reliable software.

Build Matrix Overview

The build matrix provides a snapshot of the build status across various Fedora architectures. Each architecture is listed with its corresponding status, allowing for a quick assessment of the overall build health. The matrix includes links to the Copr build logs, enabling detailed investigation of any failures.

The Build Matrix is an essential tool for assessing the health of LLVM snapshots across different architectures. It provides a comprehensive overview of build statuses, allowing developers and users to quickly identify any potential issues and take necessary actions. Each architecture's status is crucial for ensuring broad compatibility and stability of the LLVM project.

Build Status Legend

To better understand the build matrix, here’s a quick guide to the status indicators:

• :o: : Canceled
• :x: : Failed
• :ballot_box_with_check: : Forked
• :inbox_tray: : Importing
• :soon: : Pending
• :running: : Running
• :no_entry_sign: : Skipped
• :star: : Starting
• :white_check_mark: : Succeeded
• :hourglass: : Waiting
• :grey_question: : Unknown
• :warning: : Pipeline error (only relevant to testing-farm)

Latest Build Updates

Last updated: 2025-10-27T20:39:01.373819

This section provides the most recent updates on the build status. As of the last update, the following statuses were reported:

• fedora-rawhide-aarch64: The build succeeded, indicating that the LLVM snapshot is compatible with ARM64 architecture. This success is critical for a wide range of devices and systems that use ARM processors. This ensures that applications and tools built with LLVM will function correctly on ARM-based platforms.
• fedora-rawhide-i386: The build also succeeded on the i386 architecture, confirming compatibility with 32-bit Intel systems. This is important for maintaining support for older hardware and software, ensuring that LLVM can be used in diverse environments. The successful build on i386 platforms means that applications compiled with LLVM can continue to run smoothly on these systems.
• fedora-rawhide-ppc64le: The build was starting at the time of the last update. Monitoring this build is essential to ensure that the LLVM snapshot works well on PowerPC 64-bit Little Endian systems. This architecture is used in various high-performance computing environments, making its compatibility crucial for specialized applications. Continuous monitoring helps in identifying and resolving any issues specific to this architecture.
• fedora-rawhide-s390x: Unfortunately, the build failed on s390x. Further investigation is required to determine the cause of the failure. This architecture is used in IBM mainframes, and addressing the failure is a priority to ensure enterprise-level deployments of LLVM are not affected. Identifying the root cause and implementing a fix will help maintain the reliability of LLVM in critical environments.
• fedora-rawhide-x86_64: The build succeeded on x86_64, which is a crucial architecture for LLVM. This success ensures that the snapshot is stable for the most common desktop, laptop, and server environments. The successful build on x86_64 platforms confirms that the core functionality of LLVM is working as expected, benefiting a large user base.

Staying updated on these builds allows developers and users to be aware of the current status and any potential issues. Regular updates ensure transparency and facilitate timely action when problems arise. The detailed information provided in each update helps in understanding the scope and impact of any build failures.
