This probably went away a while ago.

[davide at localhost bin]$ ./clang -flto -O0 lto.c -o blah && ./blah
[davide at localhost bin]$ ./clang -flto -O1 lto.c -o blah && ./blah
[davide at localhost bin]$ ./clang -flto -O2 lto.c -o blah && ./blah
[davide at localhost bin]$ ./clang -flto -O3 lto.c -o blah && ./blah
[davide at localhost bin]$ ./clang -flto -Os lto.c -o blah && ./blah
