------- Additional Comments From pinskia at gcc dot gnu dot org 2005-05-21 12:38 ------- There is a reason why forwprop does not do this, the SSA_NAME is used twice. If we run forwprop before FRE, it will catch it in this
See PR 19703 for a case where DOM messes up catching something like this. I think forwprop already does this in some cases but I could be wrong. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21694
