The main reasons for _not_ using assembler are productivity and
maintainability, but when speed is paramount, hand-optimized assembler
will _always_ beat the compiler.

That is a myth which even very good assembly programmers can only live
up to in small inner-loop type segments. A good optimising compiler
can do global optimisations that a human would find extremely
difficult to do.
