e« Z y)a¯ The optimizer tries to constant fold expressions and modify the AST
|
|||
|
|
in place so that it should be faster to evaluate.
|
|||
|
|
|
|||
|
|
Because the AST does not contain all the scoping information and the
|
|||
|
|
compiler has to find that out, we cannot do all the optimizations we
|
|||
|
|
want. For example, loop unrolling doesn't work because unrolled loops
|
|||
|
|
would have a different scope. The solution would be a second syntax tree
|
|||
|
|
that stored the scoping rules.
