------- Additional Comments From amacleod at redhat dot com 2005-09-19 20:34 ------- Actually, it occurs to me that we might be able to make the entire SSA_NAME_DEF_STMT process completely transparent, including the setting of it. The operand cache knows whenever an SSA_NAME is added to any stmt in the IL, either real or virtual. It also knows when one is removed. Between passes would then be appropriate time to remove any which are no longer in the IL. This should resolve any issues with trying find the right places to set or reset SSA_NAME_DEF_STMT
In theory. :-) I'll take a look at it shortly and see what happens. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23940
