libfloor v0.2.2

changes since v0.2.1

  • upgraded to a Clang/LLVM/libc++ 3.8.1 toolchain (the default now), the 3.5.2 toolchain still exists as a fallback
    • NOTE: spir-encoder and applecl-encoder for writing LLVM 3.2 bitcode, a LLVM 3.5 bitcode writer for Metal, and the spir-verifier have been directly integrated into LLVM 3.8.1 (those are no longer separate binaries)
  • added initial and still experimental SPIR-V/OpenCL support, 3.8.1 toolchain only (using SPIRV-LLVM/spirv-3.6.1, SPIR/spirv-1.0, SPIRV-Tools/v2016.1)
    • NOTE: new toolchain binaries: spirv-as, spirv-dis and spirv-val (from SPIRV-Tools), and llvm-spirv (from SPIRV-LLVM)
  • added initial Metal graphics support (it is possible to write basic vertex and fragment shaders -> floor_examples for example code)
  • extended image support (added mip-mapping support with explicit lod and gradient sampling + write at explicit lod, added sampling with integer offsets, added depth compare sampling)
  • numerous vector lib and const_math improvements (there now is a math:: namespace to select between run-time and compile-time math functions)
  • added initial sub-group support (CUDA and OpenCL with extension)
  • added compute_algorithm header with generic work-group reduce, sub-group reduce, and work-group inclusive/exclusive scan functions
  • improved compilation process: this will now directly compile to bitcode and no longer to human-readable LLVM IR, and all IR fixes are now applied in the compiler
  • added support for MinGW/MSYS2 on Windows (x64/64-bit only)
  • added initial C++17 support (disabled by default, enable with "./build.sh c++17", requires Clang 3.9+)
  • countless bug fixes, performance improvements and misc new things (-> git log for all of them)

deprecation notes

  • this will be the last release to support AppleCL/OpenCL on OS X (OpenCL has been superseded by Metal on OS X/iOS and is in an utterly broken state since 10.11)
  • this will be the last release to support OS X 10.9/10.10 (going forward, only OS X 10.11+ will be supported)
  • this might be the last release to support sm_20/sm_21 (Fermi) on CUDA

Install Instructions (Linux / OS X)

  • copy this folder to /opt (-> /opt/floor)

Install Instructions (Windows)

  • copy this folder to "C:/Program Files/" or %ProgramFiles% (-> "C:/Program Files/floor")

Notes (Linux / OS X / iOS)

  • this has been compiled with the default configuration, i.e. all optional dependencies are enabled
  • when using libfloor in a project, you will thus have to have these libraries installed (-> Requirements)
  • this library comes in the form of 64-bit dynamic (Linux / OS X) and static (Linux / OS X / iOS) libraries
    • release mode libraries: libfloor_static.a and libfloor.so/libfloor.dylib
    • debug mode libraries: libfloord_static.a and libfloord.so/libfloord.dylib
  • Linux binaries have been built on Arch Linux (with clang/llvm/libc++ 3.8.0 and gcc 6.1.1), you will probably need to
    build from source on other Linux distributions (-> build instructions and requirements)

Notes (Windows with MSVC)

  • this has been compiled with the default configuration, i.e. only compute-related parts and dependencies are enabled,
    this includes CUDA, OpenCL and Host-Compute support
  • when using libfloor in a project, you will thus have to have an OpenCL SDK installed, in addition to SDL2 (-> Requirements)
  • this library comes in the form of a 32-bit static library on Windows
    • release mode library: floor.lib
    • debug mode library: floord.lib
  • binaries have been built with VS 2015 and LLVM 3.8 (http://llvm.org/builds),
    any project using libfloor will have to do the same (LLVM-vs2014 platform)

Notes (Windows with MinGW/MSYS2)

  • this has been compiled with the default configuration, i.e. all optional dependencies are enabled
  • when using libfloor in a project, you will thus have to have these libraries installed (-> Requirements)
  • this library comes in the form of a 64-bit static library on Windows with MinGW/MSYS2
    • release mode library: libfloor_static.a
    • debug mode library: libfloord_static.a
  • libfloor binaries have been built with clang/llvm 3.8.0 and libstdc++ 5.4.0, toolchains have been built with gcc 5.4.0
