------- 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.
