I.e., "-Os > -fno-strict-aliasing" should work. That does work, but there are still things you can't turn off with -f. They're half-aliases. toplev.c::parse_options_and_default_flags does set -f flags based on the optimization level, but there is still a whole lot of gcc code that directly tests the value of optimize and optimize_size. -- Dan Nelson dnelson_at_allantgroup.comReceived on Tue Jul 29 2003 - 12:09:09 UTC
