- refactor: Move GCC specfile logic into new compiler_config.go module
- feat(build): Add clang configuration file support for package metadata injection
This is preparation for also adding clang configuration. Co-Authored-By: Claude Sonnet 4.5 <[email protected]> Signed-off-by: dann frazier <[email protected]>
…a injection This adds Package Metadata ELF notes for binaries built with Clang, like we already have for GCC. We do this by creating user configuration files for clang that override the system configuration files. We assume that there's a system configuration file for each supported version of clang (provided by openssf-compiler-options in wolfi), so we scan for those to determine which user configuration files are required. If we find any clang system configuration files, we create a ~/.melange.clang.cfg file that adds the necessary linker config. We then create a user config file counterpart for each system config file that includes ~/.melange.clang.cfg *and* includes the system config file that we've overridden, making sure we don't lose our hardening flags. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]> Signed-off-by: dann frazier <[email protected]>
