------- Comment #3 from mikpe at it dot uu dot se 2009-07-11 20:20 -------
It seems that cpu type and tuning options make a difference here. If I compile
with -mcpu and -mtune referring to a cpu that does not imply FL_LDSCHED, such
as arm740t, then I get the broken code that clobbers r0 before loading r3.
Changing cpu and tune types to a cpu that does imply FL_LDSCHED, such as arm8
or xscale, then r3 is loaded before r0 is clobbered and the sub becomes an rsb.
