[Bug tree-optimization/32306] [4.2/4.3 Regression] Bad Code generation ( Tree optimization )



------- Comment #5 from pranav dot bhandarkar at gmail dot com  2007-06-12 21:10 -------
Created an attachment (id=13694)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13694&action=view)
A smaller Testcase that displays the said behaviour

Reduced the testcase. Reducing to less than b1 thru b6 results in the compiler
being able to combine the if conditions at the tree level. Therefore couldnt
reduce it to less than b6. array elements written have been reduced to 4.
