profiling library smaller than non-profiling, while it contains more symbols. Why?

This is _not_ unexpected with different processor architectures, and thus
different instruction sets.

Speculation: the values lfor the .LC* variables look like bit-masks -- it 
may be that ia64 has opcodes that allow immediate operannds, obviating
the need for a 'data' consntat in memory.

"Something" in the source causes different processor-specific code to be
generated -- one processor uses 'data' constants, the other doesn't.
