------- Comment #7 from rakdver at gcc dot gnu dot org 2007-01-09 15:30 ------- (In reply to comment #6) > It seems to be IVOPTs rewriting introduces the trees. Testcase:
Which happens because fold causes the number of iterations of the loop to be something like e + ~f, and then is not able to deal with the expressions like the one in the testcase. I will fix tree-affine to deal with this, but perhaps it would be preferable not to perform this transformation in fold at all, and leave it for simplification on rtl. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30322
