Update of /cvsroot/monetdb/pathfinder/compiler
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv11089
Modified Files:
compile.c
Log Message:
-- First steps to get rid of bit-encoded column names:
o The planner and the MIL generation do not rely
on bit-encoded columns anymore.
o A global counter allows to assign new column names
without the need to analyze the plan before.
o Operator la_eqjoin_unq is only introduced in the
join pushdown phase and a normal eqjoin is available
for all other phases working on unique column names.
o Changed the required node optimization phase to cope
with unique column names.
