Author: Richard Plangger <rich at pasra.at>
Branch: vecopt
Changeset: r77496:3931485d86f0
Date: 2015-05-22 17:11 +0200
http://bitbucket.org/pypy/pypy/changeset/3931485d86f0/
Log: resolved problem with guard strengthening (boolinverse needed if
guard_false) guard implication supported (might not be needed) added
a test to test if vecopt conforms the rpython (thx fijal) removed
translation using test_zrpy_vecopt
