What is gcc?

This repository is a mirror of the GCC project, which is the software tool used to translate code written in languages like C and C++ into programs that computers can actually run. GCC is a foundational piece of software used by developers worldwide. However, this particular GitHub copy isn't just a straight duplicate. It also serves as a public workspace where developers from Oracle can share their ongoing work and completed contributions to the broader GCC project. At a high level, the original GCC codebase lives on a different website, and this GitHub location regularly pulls in updates from that main source. What makes it unique are the extra branches it contains. In software development, a branch is essentially a separate lane of work. Oracle developers use these lanes to share work-in-progress patches that haven't been officially approved yet, allowing reviewers to easily test proposed changes. They also maintain lanes for work that has already been accepted into the main project, providing a convenient history of Oracle's contributions. The primary users of this repository are the core GCC developers and reviewers who evaluate proposed changes before they go live. By hosting these patches on GitHub, Oracle makes it much easier for the broader community to view, test, and review their proposed updates in context. If you are a developer contributing to GCC or trying to understand upcoming features, you might look here to see what Oracle's team is currently building or testing. It is important to note that the code here is explicitly labeled as a technology preview and is not officially supported. This means you wouldn't want to use these work-in-progress versions to build production software, as the code hasn't been finalized or fully vetted. It is strictly a staging area for testing and review.
