--- Comment #27 from Andreas Schwab <sch...@linux-m68k.org> ---
On ia64, even after applying all patches, there is still an ICE:
configure:4279: /usr/local/gcc/test/Build/./gcc/xgcc
-B/usr/local/gcc/test/Build/./gcc/ -B/usr/ia64-suse-linux/bin/

/usr/ia64-suse-linux/sys-include -o conftest -g -O2 conftest.c >&5
during RTL pass: mach
conftest.c: In function 'main':
conftest.c:41:1: internal compiler error: in vt_initialize, at
var-tracking.c:10185
