[Richard Earnshaw]

Both native and cross building of all ARM configurations has been broken 
since this patch was installed:

        * toplev.c (flag_sched2_use_superblocks, flag_sched2_use_traces): 
New
        global variables.
        (lang_independent_options):  Add -fsched2-use-superblocks
        -fsced2-use-traces.
        (rest_of_compilation): Deal with it.
        * invoke.texi (-fsched2-use-traces, fsched2-use-superblocks):  
Declare.
        * flags.h (flag_sched2_use_superblocks, flag_sched2_use_traces):
        Declare.
        * rtl.h (reg_to_stack):  Update prototype.
        * reg-stack.c (reg_to_stack): Return when something has changed;
        update liveness when executing after superblock scheduling.

        * combine.c (simplify_shift_const):  Simplify few special cases
        into constants.

See http://gcc.gnu.org/ml/gcc/2003-02/msg01521.html for some analysis.

Is there any prospect of a fix soon, or should we consider reverting this?
