Subject: [Bug tree-optimization/15347] [tree-ssa] fold if ("<12ers" + 1 == 0).
Date: Thu, 03 Jun 2004 23:22:00 -0000 [thread overview]

I should note that "12ers" == 0 is folded to false by:
/* If this is an equality comparison of the address of a non-weak
object against zero, then we know the result. */
So improving that part will help.
