[ I am thus forwarding a description by
Steve Kargl <sgk@troutmask.apl.washington.edu>, by permisson of Steve. ]
My ICE [on FreeBSD-CURRENT] is:
gcc -I. -I. -I../include -I./../include -I/usr/local/include \
-march=athlon -O -pipe -c ./iconv.c -fPIC -DPIC -o iconv.lo
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 79)
(const_int 128 [0x80])) -1 (nil)
(nil))
gbkext1.h:852: Internal compiler error in extract_insn, at recog.c:2150
I've tried the following combinations of CFLAGS with
libiconv 1.8. Hopefully, it helps isolate the problem.
configure CFLAGS="-march=athlon -O0" <-- No ICE.
configure CFLAGS="-march=athlon -O1" <-- ICE.
configure CFLAGS="-march=athlon -O2" <-- ICE.
configure CFLAGS="-O0" <-- No ICE.
configure CFLAGS="-O1" <-- No ICE.
configure CFLAGS="-O2" <-- No ICE.
configure CFLAGS="-mcpu=athlon -O0" <-- No ICE.
configure CFLAGS="-mcpu=athlon -O1" <-- No ICE.
configure CFLAGS="-mcpu=athlon -O2" <-- No ICE.
