------- Comment #2 from schwab at suse dot de 2008-07-25 21:33 -------
The bug is in dse.c:replace_inc_dec:
add_insn_before (data->insn,
gen_rtx_SET (Pmode, r1,
gen_rtx_PLUS (Pmode, r1, c)),
NULL);
This does not make any sense: the rtx to be added must satisfy INSN_P, LABEL_P,
BARRIER_P or NOTE_P, and the first two arguments are swapped.
