Last change on this file was 16628, checked in by westram, 8 years ago
  • reintegrates 'vectorize' into 'trunk'
    • fixes #700
      • documented vectorization-checks
      • fine-grained check based on gcc-version
    • drops old gcc-versions (<4.4.3)
    • new attribute __ATTR__DONT_VECTORIZE
      • disabled vectorization of POS_TREE2::init_static() for newer gcc-versions (generated code fails tests)
    • added a bunch of new vectorization-checks (probably irrelevant to overall performance)
  • adds: log:branches/vectorize@15531:16585,16595:16627
