[Bug optimization/13424] [3.4/3.5 Regression] gcc.dg/20031202-1.c is miscompiled


------- Additional Comments From rth at gcc dot gnu dot org  2004-03-02 23:43 -------
I am distinctly tired of this RTX_UNCHANGING_P mess.  It's demonstrably so
badly designed that no-one has a good handle on how to fix it properly.

I propose that it simply be disabled on 3.4/3.5, and hope to fix the problem
differently with tree-ssa.
