The problem got worse after the tree-ssa merge. Before the merge, the unused symbols would get generated if the code fragment were compiled at -O2; the symbols wouldn't be generated if -fno-unit-at-a-time was added to the compile line. With the current top-of-tree, the symbols are always produced -- -O0, -O2, and with or without -fno-unit-at-a-time. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14639
