%description
The OpenCL Conformance Test Suite (CTS) from the Khronos Group validates
OpenCL implementations for conformance to the OpenCL specification. It
includes tests for API, compiler, images, buffers, atomics, math functions,
SPIR-V support, and more.

Tests are installed to %{ctsdir} and must be run from that directory
since they expect data files in the current working directory.

# Upstream uses -Wno-format for some targets which conflicts with Fedora's
# -Werror=format-security in hardened CFLAGS. Strip -Werror flags.
