[Bug target/21100] New: ICE: unrecognizable insn for -march=pentium-mmx

[jochang at gmail dot com]

ICE on gcc 4.0.0rc2, but both 3.3.5 and 3.4.3 work.
No ICE if change pentium-mmx to pentium2.

$ /usr/local/gcc-4.0/bin/g++ -c -march=pentium-mmx 2.cpp
2.cpp: In function 'void f()':
2.cpp:30: error: unrecognizable insn:
(insn 13 12 14 0 (set (mem/i:V2SI (pre_dec:SI (reg/f:SI 7 sp)) [0 S8 A64])
        (reg:V2SI 61 [ a ])) -1 (nil)
    (expr_list:REG_DEAD (reg:V2SI 61 [ a ])
        (nil)))
2.cpp:30: internal compiler error: in extract_insn, at recog.c:2020
