Hi, Ok to push if bootstrap and regtest (on x86_64 linux) succeeds?
Thanks, Filip Kastl -- 8< -- I increment the index variable in a loop even when I do vec::unordered_remove() which causes the vector traversal to miss some elements. Mikael notified me of this mistake I made in my last patch. gcc/ChangeLog: * gimple-ssa-sccopy.cc (scc_copy_prop::propagate): Don't increment after vec::unordered_remove().
