[Bug c/24484] New: unrecognizable insn in extract_insn, at recog.c:2083

["richard at hirner dot at" <gcc-bugzilla at gcc dot gnu dot org>]

PROBLEM:
Tried to compile libapreq2-2.06 from the FreeBSD ports collection. Failed with
this message:
---------------------------
cc -DHAVE_CONFIG_H -I. -I. -I../include
-I/usr/local/include/apache2/modules/perl -I/usr/local/include/apache2
-I/usr/local/include -D_REENTRANT -D_THREAD_SAFE -O -pipe -march=athlon -c
util.c -MT util.lo -MD -MP -MF .deps/util.TPlo  -fPIC -DPIC -o .libs/util.o
util.c: In function `apreq_atoi64f':
util.c:52: error: unrecognizable insn:
(insn 66 172 67 8 util.c:44 (set (reg/f:SI 75)
        (match_insn 677090144 ("C"))) -1 (nil)
    (nil))
util.c:52: internal compiler error: in extract_insn, at recog.c:2083
Please submit a full bug report,

SYSTEM:
FreeBSD 5.3-RELEASE-p18 (Mon Jul 11 15:26:16 CEST 2005)
/usr/obj/usr/src/sys/DEVVV01 i386

GCC VERSION:
#gcc -v
Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.4.2 [FreeBSD] 20040728

COMMAND LINE:
cc -DHAVE_CONFIG_H -I. -I. -I../include
-I/usr/local/include/apache2/modules/perl -I/usr/local/include/apache2
-I/usr/local/include -D_REENTRANT -D_THREAD_SAFE -O -pipe -march=athlon -c
util.c -MT util.lo -MD -MP -MF .deps/util.TPlo  -fPIC -DPIC -o .libs/util.o
Bug appears without -march and -O, too

Will append the .i file. Do you need more source code? It is available from the
libapreq page.
