[Bug target/33104] New: Missing error check in .md converter

["kai-gcc-bugs at khms dot westfalen dot de" <gcc-bugzilla at gcc dot gnu dot org>]

(define_insn "mov<mode>"
        [(set   (match_operand:MVM 0 "vg_general_operand" "=r,   <o>, r, t, r")
                (match_operand:MVM 1 "vg_general_operand" "r<o>, r,   t, r,
I"))]
        ""
        "mov<mode> %0,%1")

When both match_operands mistakenly mention 0 (instead of 0 and 1 as above),
then ...

build/genextract $src/gcc/config/$machine/$machine.md \
          insn-conditions.md > tmp-extract.c
genextract: Internal error: abort in VEC_safe_set_locstr, at genextract.c:190

... which is not exactly a useful diagnostic.
