: is there an ada equivelent to 'register' in C/C++?
In Ada 95, any local variable not declared "aliased" is a candidate
for living in a machine register. The compiler decides based
on usage.
For global variables, some C compilers support the use of
the "register" keyword, but normally there is also some kind
of pragma to identify which register should be devoted to
the variable. The same kind of pragma could certainly be
implemented in Ada (and may already be so in some compilers) for
assigning a global variable to a machine register.
