We can use PREFERRED_RELOAD_CLASS and PREFERRED_OUTPUT_RELOAD_CLASS. I am not sure if the fix is over-eager, but it works great on libsse2. Every fld that was there disappears, and from a cursory check, in current mainline's code all of them could have been inherited. Patches are at: - http://gcc.gnu.org/ml/gcc-patches/2005-07/msg00914.html (regclass) - http://gcc.gnu.org/ml/gcc-patches/2005-07/msg00983.html (reload+i386) It is also necessary to remove from the MD the `#' hints for regclass, with sed -i 's/#[^",\][^",]*\([",]\)/\1/g' i386.md Paolo -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19653
