%description
libclc is an open source, BSD licensed implementation of the library
requirements of the OpenCL C programming language, as specified by the
OpenCL 1.1 Specification. The following sections of the specification
impose library requirements:
* 6.1: Supported Data Types
* 6.2.3: Explicit Conversions
* 6.2.4.2: Reinterpreting Types Using as_type() and as_typen()
* 6.9: Preprocessor Directives and Macros
* 6.11: Built-in Functions
* 9.3: Double Precision Floating-Point
* 9.4: 64-bit Atomics
* 9.5: Writing to 3D image memory objects
* 9.6: Half Precision Floating-Point
libclc is intended to be used with the Clang compiler's OpenCL frontend.
libclc is designed to be portable and extensible. To this end, it provides
generic implementations of most library requirements, allowing the target
to override the generic implementation at the granularity of individual
functions.
libclc currently only supports the PTX target, but support for more
targets is welcome.

%changelog
* Thu Mar 28 2024 L.A. Kostis <lakostis@altlinux.ru> 18.1.2-alt1
- 18.1.2.
* Fri Nov 10 2023 Alexey Sheplyakov <asheplyakov@altlinux.org> 17.0.4-alt2
- NMU: fixed FTBFS on LoongArch:
+ disable LTO (not used when building bitcode, causes problems on LoongArch)
+ do not force linking with lld (native linker is used only for compiling
build tools like utils/prepare-builtins and CMake test programs, causes
failure on LoongArch).
* Wed Nov 08 2023 L.A. Kostis <lakostis@altlinux.ru> 17.0.4-alt1
- 17.0.4.
- BR: added clspv.
* Wed Sep 13 2023 L.A. Kostis <lakostis@altlinux.ru> 16.0.5-alt2
- armh: disable LTO and compile with clang.
- .spec: cleanup.
* Wed Sep 13 2023 L.A. Kostis <lakostis@altlinux.ru> 16.0.5-alt1.1
- fix FTBFS: add missing llvm -devel packages.
* Mon Jun 12 2023 L.A. Kostis <lakostis@altlinux.ru> 16.0.5-alt1
- 16.0.5.
- armh: use gcc as CXX (clang++ segfaults).
- Made it noarch as clc code is IR code.
- Built with llvm16 for better code optimisation.
