Addressing modes for static and local variables

سؤال
Why are static variables addressed directly while locals are addressed indirectly? I cannot see where the indirection comes from for locals!
المحلول
In languages that allow functions to be used recursively, locals need to be addressed indirectly (via the stack pointer).
C, however, has also static local variables, hence static
and local
are not necessarily mutually exclusive concepts.
