%description
The Intel Graphics Compiler (IGC) for OpenCL is an LLVM-based compiler
for OpenCL and oneAPI Level Zero, specifically targeting Intel graphics
hardware architectures. It translates OpenCL C and SPIR-V code into
Intel GPU assembly.

%package -n intel-igc-core
Summary:        Intel Graphics Compiler core libraries
Group:          System Environment/Libraries
Requires:       %{name} = %{version}-%{release}

%description -n intel-igc-core
This package contains the core libraries for the Intel Graphics Compiler (IGC).
It is a fundamental component for Intel's compute runtime and graphics stack.

%package -n intel-igc-opencl
Summary:        Intel Graphics Compiler OpenCL component
Group:          System Environment/Libraries
Requires:       %{name} = %{version}-%{release}
Requires:       intel-igc-core = %{version}-%{release}

%description -n intel-igc-opencl
This package contains the OpenCL-specific components of the Intel Graphics
Compiler (IGC), including the OpenCL frontend and related libraries.

%package -n intel-igc-devel
Summary:        Development files for Intel Graphics Compiler
Group:          Development/Libraries
Requires:       %{name} = %{version}-%{release}
Requires:       intel-igc-opencl = %{version}-%{release}
# Typically, development files are bundled in one package.

%description -n intel-igc-devel
This package contains the development headers, static libraries, and
CMake configuration files for building applications that integrate
with or require components of the Intel Graphics Compiler.
