My point was that a few virtul function calls doing nop should (and in
fact if
you benchmark _M_insert_float this is the case) not cost more that one
function call doing memcopy inside, however.
FYI, the cost of a virtual function is architecture dependent. On
HP PA, for instance, virtual function calls are extremely expensive
(about 5 times more than ordinary function calls), while on HP IPF
and SPARC they are only about twice as expensive.
