Update of /cvsroot/monetdb/pathfinder/compiler/debug
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv14603/debug
Modified Files:
logdebug.c
Log Message:
-- Extended the required value property to also infer
whether columns are only used in predicates.
-- Added rewrite that turns fn:number into the relaxed variant
that ignores NaN values---values that cannot be cast---based
on the observation if fn:number is applied on predicates only.
