61ef30381c * Only synchronise regvars after a loop (and only those regvars 
which are used in the loop). The compiler makes now much
    more efficient use of registers for register variables (and
    different regvars can now also share the same register if
    their live range does not overlap)

daniel
8cbd40c2f0 * The for node does a check if the first comparision can be skipped. I moved 
the check from the second pass to the resulttype pass. The advantage is
  that the state tracker can now decide to skip the first comparision too.

95427989a6 * Loops should not be aligned when optimizing for size 2002-07-20 08:14:24 +00:00
daniel
399036f1c2 * State tracker work 
* The whilen and repeatn are now completely unified into whilerepeatn. This
  allows the state tracker to change while nodes automatically into
  repeat nodes.
* Resulttypepass improvements to the notn. 'not not a' is optimized away and
  'not(a>b)' is optimized into 'a<=b'.
* Resulttypepass improvements to the whilerepeatn. 'while not a' is optimized
  by removing the notn and later switchting the true and falselabels. The
  same is done with 'repeat until not a'.

    calls to cgobj

    u32bit then the other is typecasted also to u32bit without giving
    a rangecheck warning/error.
  * fixed pascal calling method with reversing also the high tree in
    the parast, detected by tcalcst3 test
