/* To determine the minimum scope of a local variable, all (braced)
|
|
scopes are numbered consecutively. Next we maintain an array which
|
|
maps the nesting depth (level) onto the scope number; we record
|
|
the scope number of the first application of a local variable
|
|
in its definition. Each further application requires that the
|
|
level of the variable be at least large enough to comprise both
|
|
the present scope and that of its first application. That level
|
|
number is determined by searching the array and is then recorded in
|
|
the definition (beacuse it is always equal to or smaller than the
|
|
level already there).
|
|
|
|
The array is implemented as a linked list of struct brace.
