Changeset: r51524:ab36137540d5
Date: 2012-01-20 16:21 +0200
http://bitbucket.org/pypy/pypy/changeset/ab36137540d5/
Log: merge numpy-indexing-by-arrays-bool, this adds some basic indexing
by bool arrays (only when shapes match) as well as bitwise_and/or
and a few helper functions. More work on indexing by arrays to be
done in the future
