you aren't doing anything different than we normally do now. I prefer this over adding a flag to bsi_remove for sure. I looked into an alternative which follows up on the thread we had going. A better longer term solution is to have it all taken care of automatically. I got most of the way through implementing the automatic setting and clearing of SSA_NAME_DEF_STMT as stmts are processed by build_stmt_operands(). That is the one place where we know precisely when a stmt has entered and exited the IL. Then between passes it is trivial to check if SSA_NAME_DEF_STMT is NULL and free the ssa-name. I had it mostly working, but the changes are pretty invasive as no one ever has to set or clear SSA_NAME_DEF_STMT any more, its always simply "right". Its too invasive for stage 3 thats for sure. I'll revisit it when we get back to stage 1 and test out performance and whether its really what we want to do. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23940
