General Improvements

\n+
    \n+
  • Link-Time Optimization now supports better handling of toplevel asm\n+ statements with -flto-toplevel-asm-heuristics.
    • \n+
  • The vectorizer now supports vectorizing of uncounted loops and a wider\n+ class of loops with early exits.
    • \n+
  • The vectorizer is now more flexible in identifying in-loop parallelism\n+ of reductions.
