Package: grep
Tags: patch

dfaexec() allocates and deallocates many buffers in non-UTF8 locales, but
it's very inefficient.

If put them on struct dfa and reuse them, when use not regex but DFA for
ANYCHAR, it will speed up about 20-30% in non-UTF8 locales.

Thanks. Paolo wrote it up in <http://bugs.gnu.org/17156#11>, and I just now tweaked its ChangeLog and merged the code and installed it (patch attached). I followed up with minor cleanups (2nd patch attached).
