The -m[no-]vrsave option is ignored on 4.3.0 (and it seems on the trunk as of 2008/5/28 it still is). Note the old form -mvrsave=no does work.
Other -m[no-] options also fail to work with 4.3.0 but (at least some) of them have apparently been fixed on the trunk (as of today) but -m[no-]vrsave has not. -- Summary: -mvrsave / -mno-vrsave ignored Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: strauman at slac dot stanford dot edu GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: powerpc-unknown-rtems http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36358
