Change Logs

* Wed Nov 23 2022 Dominique Leuenberger <>
- Update to version 1.18.1:
  + A minor ISPC update with security fix: zlib dependency was
- Drop zlib-devel BuildRequires: no longer needed.
* Wed Oct 19 2022 Stefan BrĂ¼ns <>
- Enable aarch64 builds, disable (broken) aarch32
- Fix CMake config, remove static library from exported targets
- Enable tests
* Fri Oct 07 2022 Hans-Peter Jansen <>
- Update to 1.18.0
- Package separate devel and library packages
- Specify a certain llvm version (llvm15 is supported from the
  next release only
- Adopt {n}curses support
- Make ispc depend on ispc-devel for backward compatibility
* Sun Apr 24 2022 Hans-Peter Jansen <>
- Update to 1.17.0
- Switch to default clang/llvm build
* Tue Oct 12 2021 Hans-Peter Jansen <>
- Update to 1.16.1
- Remove fix-llvm12-fallout.patch, upstreamed
- Explicitly use clang12 to build
* Sun May 02 2021 Hans-Peter Jansen <>
- Add fix-llvm12-fallout.patch with some LLVM API changes backported
  as a temporary measure to fix LLVM 12 builds
* Sun Apr 18 2021 andy great <>
- Update to 1.15.0.
  * New loop unroll pragmas: #pragma unroll and #pragma nounroll
    directives provide loop unrolling optimization hints to the
    compiler. This pragma may be used immediately before a loop
    statement. Currently, this functionality is limited to uniform
    for and do-while.
  * More efficient packed_[load|store]_active() stdlib functions
    implementation (up to 2.5x faster), which now supports 64 bit types.
  * New cpus: icelake-server, tigerlake , alderlake, sapphirerapids.
  * Several stability fixes related to SOA types, bool varying type
    initialization, broken alignment information, type scoping.
  * Compile time improvements.
  * Initial support of ahead of time compilation to oneAPI Level Zero
    binary format using --emit-zebin switch. You can use this binary
    from ISPC Runtime by setting
  * ISPCRT_USE_ZEBIN env variable to 1. Please note that SPIR-V format
    is still a recommended and default way.
  * Initial function pointers implementation.
  * Global atomics support.
  * Double math functions support.
  * Memory functions support.
  * Reworked masking approach. We disabled genx hardware mask by
    default and use a software mask by default.
  * Improved address spaces differentiation.
  * Initial debug support.
  * TGLLP (TigerLake mobile CPU) support (--cpu=TGLLP).
* Fri Nov 06 2020 Hans-Peter Jansen <>
Note, we don't do any GPU builds yet, because
  - API is not stable
  - additional dependencies (that are not available, yet)
- Update to version v1.14.1:
  A minor ISPC update with a bug fix for AVX512 detection problem on macOS
  (for more details see issue #1854) and update of GPU version to use Level0 v1.0.
  CPU binaries are based on patched LLVM 10.0.1.
- Update to version v1.14.0:
  An ISPC release with several improvements for CPU and initial support of Intel
  graphics hardware architectures. The binaries in this release include CPU versions
  for Windows, Linux, and macOS, as previous releases, plus a GPU-enabled Linux binary,
  which supports both CPU and GPU. CPU binaries are based on patched LLVM 10.0.1.
  CPU changes include:
  + new avx2-i8x32, avx2-i16x16, avx512skx-i8x64, avx512skx-i16x32 targets.
    "generic" targets were removed.
  + several stability fixes, including bugs discovered during fuzzing ISPC by YARPGen.
  + integer division performance improvements.
  + support for __vectorcall calling convention on Windows x64 (enabled by
