reedsolomon v0.0.4.3 Release Notes

Release Date: 2017-01-13 // about 8 years ago

  • Highlights since version 0.0.4.2:

    Use __builtin_shuffle for 'generic' SIMD code

    Some compilers, including GCC, provide a built-in function to efficiently shuffle vector elements without resorting to platform-specific SIMD intrinsics. If available, we now use this function instead of a hand-written byte-wise implementation for the 'generic' implementations of the SIMD routines. For non-generic implementations, the code generated by __builtin_shuffle is slightly more complicated than the hand-written intrinsics code.

    👀 See commit 724dddb for more information, including how compiler support is checked in the ./configure script.

    Detect and use system-provided __get_cpuid_count

    The X86 system headers coming with GCC 6.3 now provide a definition of __get_cpuid_count in cpuid.h. We define said function in a cbits module as well (for compilers not providing an implementation in their
    headers), which conflicts.

    🔧 A test for the declaration is now performed by ./configure, and if provided by the system, this version of the routine is used.

    🛠 Fix Haddock builds

    📚 Due to an oversight in build-tools/ghc-wrapper, when using GHC 8 Haddock would fail building API documentation for the package: the wrapper generated more output than plain GHC.
