analyze the tail calls in general, passing the results to the rtl level
|
2004-05-13 08:41:07 +02:00
|
|
|
where they are used for sibcall optimization.
|
|
|
|
|
|
|
|
In addition to the standard tail recursion elimination, we handle the most
|
|
|
|
trivial cases of making the call tail recursive by creating accumulators.
|
|
|
|
For example the following function
|
|
|
|
|
|
|
|
int sum (int n)
|
|
|
|
{
|
|
|
|
if (n > 0)
|
|
|
|
return n + sum (n - 1);
|
|
|
|
else
|
|
|
|
return 0;
|
|
|
|
}
|
|
|
|
|
|
|
|
is transformed into
|
|
|
|
|
|
|
|
int sum (int n)
|
|
|
|
{
|
|
|
|
int acc = 0;
|
|
|
|
|
|
|
|
while (n > 0)
|
|
|
|
acc += n--;
|
|
|
|
|
|
|
|
return acc;
|
|
|
|
}
|
|
|
|
|
2009-11-25 11:55:54 +01:00
|
|
|
To do this, we maintain two accumulators (a_acc and m_acc) that indicate
|
2004-05-13 08:41:07 +02:00
|
|
|
when we reach the return x statement, we should return a_acc + x * m_acc
|
|
|
|
instead. They are initially initialized to 0 and 1, respectively,
|
|
|
|
so the semantics of the function is obviously preserved. If we are
|
|
|
|
guaranteed that the value of the accumulator never change, we
|
|
|
|
omit the accumulator.
|
|
|
|
|
|
|
|
There are three cases how the function may exit. The first one is
|
2004-06-03 14:07:47 +02:00
|
|
|
handled in adjust_return_value, the other two in adjust_accumulator_values
|
2004-05-13 08:41:07 +02:00
|
|
|
(the second case is actually a special case of the third one and we
|
|
|
|
present it separately just for clarity):
|
|
|
|
|
|
|
|
1) Just return x, where x is not in any of the remaining special shapes.
|
|
|
|
We rewrite this to a gimple equivalent of return m_acc * x + a_acc.
|

|
|
|
|
2004-05-13 08:41:07 +02:00
|
|
|
2) return f (...), where f is the current function, is rewritten in a

|
|
|
|
are unchanged.

3) return a + m * f(...), where a and m do not depend on call to f.
|
|
|
|
To preserve the semantics described before we want this to be rewritten
|
|
|
|
in such a way that we finally return
|
|
|
|
|
|
|
|
a_acc + (a + m * f(...)) * m_acc = (a_acc + a * m_acc) + (m * m_acc) * f(...).
|
|
|
|
|
|
|
|
I.e. we increase a_acc by a * m_acc, multiply m_acc by m and
|
|
|
|
eliminate the tail call to f. Special cases when the value is just
|
|
|
|
added or just multiplied are obtained by setting a = 0 or m = 1.

This situation happens, in (e.g.) "*p = foo()" where foo returns a

itself as that argument to foo, but it's too early to do this here,
