The comment for note_stores() (in rtlanal.c) says: /* Call FUN on each register or MEM that is stored into or clobbered by X. (X would be the pattern of an insn).
But this doesn't happen when a register is modified by e.g. a PRE_DEC expression. Is this an oversight or intentional? If intentional, the comment should say so and perhaps also why. -- Rask Ingemann Lambertsen
