Update of /cvsroot/monetdb/pathfinder/compiler/algebra
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv13092/algebra
Modified Files:
algopt.c planner.c properties.c
Log Message:
-- Added node based properties that check (top-down) if ...
... the node may be used (indirectly) for serialization
... the node id may be used
... the node order may be used
... the node values may be accessed
... a downward axis is applied lateron
(child, descendant, descendant-or-self)
... a side-way axis is applied lateron
(following, following-sibling, preceding, preceding-sibling)
... an upward axis is applied lateron
(parent, ancestor, ancestor-or-self)
... a self axis is applied lateron
(self, ancestor-or-self, descendant-or-self)
... the node may be used as input to node construction
-- Exploited the node base property that checks for the downward axis
property:
For every content constructor whose input is not queried we can
use the physical shallow content constructor that makes use of
references instead of creating a subtree copy.
(This sped up the execution time of XMark Q10 (scale factor 1)
by 60% and the execution time of XMark Q15 by 150%.)
