Version 1.8.1

4 hours ago

Version 1.8.1 includes logic for runtime mode selection for distributing a generic binary for a particular platform and allowing selection of particular implementations based on the specific instruction set architecture available on the host system. For example a build server can create a shared object that supports SSE, AVX, and AVX512 and deploy it to a system that only has SSE and AVX support. Autotools support continues with as of yet full feature support. This will likely be removed for version 2.0.0. Also included is a constant struct with build information such as version, Git hash, date, and other compile-time and hardware acceleration options.

NOTE: AltiVec support is temporarily put on hold due to memory alignment
specifics that do not allow only run-time execution selection.

  • build
    • fixed typos and inconsistent formatting
    • consolidating configuration file to support both cmake and autotools build environments.
    • added option for strict compilation (treat warnings as errors)
    • added compile-time build information (version, git hash, build OS, etc.) to binary.
    • fixed issues with 'autoscript' target breaking cross-compilation and library install directory (thanks @dawkagaming)
    • fixed issues with installation destination, 32-bit architectures, and conditional autoscript builds (thanks again, @dawkagaming)
  • core
    • added timer object for handling run-time execution testing
    • added cpuinfo struct to support compile-time/run-time mode deconfliction
    • added sysinfo struct to support run-time mode definition such as hardware acceleration and core count. Would ideally include clock rate or rough indication of processor capability.
  • dotprod
    • added run-time mode selection for vector dot product, allowing for distributed binary to operate across various architectures with instruction sets for acceleration
  • filter
    • firdespm: fixed long-standing out-of-bounds read element
    • firdespm: cleaning up debugging macros
    • iirdes: fixing bug with complex pair resolution
  • math
    • fixed long-standing bug with poly/findroots out-of-bounds error
  • modem
    • apsk: fixed issue with negative modulo (C99)
    • cpfskdem: properly resetting coherent demodulation
    • fskdem: fixing frequency error estimate
  • optim
