Ping for these two changes: http://gcc.gnu.org/ml/gcc-patches/2011-04/msg00194.html http://gcc.gnu.org/ml/gcc-patches/2011-04/msg00195.html
They just add a mode argument to TARGET_CANNOT_FORCE_CONST_MEM and LEGITIMATE_CONSTANT_P (turning the latter into a hook). This is directly needed for: http://gcc.gnu.org/ml/gcc-patches/2011-04/msg00200.html but it seems like useful information for the back-end to have in any case. Richard
