Hi,
During expression hash table construction in gcse pass(gcc vercion 3.4.1),
expressions like a*b does not get included into the expression hash table.
Such expressions occur in PARALLEL along with clobbers. This means that
such expression are not being subjected to PRE. Isn't it surprising? Can
anyone throw light on this.
Anticipating quick reply.
Thanks,
