%description
Pinned Mesa-maintained 32-bit and 64-bit SPIR-V built-in libraries for
Rusticl. This package replaces only the matching Fedora SPIR-V subset.
The installed libclc22 package and its other target libraries remain intact.
Compatibility with another Fedora libclc22 revision requires separate review.
