See gcc-3.4-20030924/gcc/config/rs6000/altivec.md, line 673. Change
vmsumubm to vmsummbm. That is, the bug persists through this snapshot.
667 (define_insn "altivec_vmsummbm"
668 [(set (match_operand:V4SI 0 "register_operand" "=v")
669 (unspec:V4SI [(match_operand:V16QI 1 "register_operand" "v")
670 (match_operand:V16QI 2 "register_operand" "v")
671 (match_operand:V4SI 3 "register_operand" "v")] 66))]
672 "TARGET_ALTIVEC"
673 "vmsumubm %0,%1,%2,%3"
674 [(set_attr "type" "veccomplex")])
BTW, on this bug submission page, there is no way to attach files to conform,
I think, to the guidelines.
