* 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?
