>Description:
While compiling with -march=athlon -O2, the program ibiconv-1.8 I receive

gcc -I. -I. -I../include -I./../include -O2 -march=athlon -fPIC -DPIC -DLIBICONV_PLUG ./iconv.c -x none ../libcharset/lib/localcharset.lo -shared -o libiconv_plug_linux.so 
In file included from gbk.h:64,
                 from converters.h:202,
                 from iconv.c:67:
gbkext1.h: In function `gbkext1_mbtowc':
gbkext1.h:852: unrecognizable insn:
(insn 157 155 159 (set (reg:QI 83)
        (const_int 128 [0x80])) -1 (nil)
    (nil))
gbkext1.h:852: Internal compiler error in extract_insn, at recog.c:2148
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
make[1]: *** [libiconv_plug_linux.so] Error 1

But if I do not compile with -O2 or -march=athlon it works fine. I have included the gbkext1.h file and a more detailed error message. I previously posted this as # 7449
>How-To-Repeat:
Compile libiconv 1.8 with GCC 3.1.1 or GCC 3.2.
