Most errors are gone, thanks.  I see these errors with the trunk
LAST_UPDATED Wed Mar 13 16:27:53 GMT 2002 which look related to
your changes:

cris-axis-elf:
g77.f-torture/execute/f90-intrinsic-bit.f: In program `MAIN__':
g77.f-torture/execute/f90-intrinsic-bit.f:399: Internal compiler error in purge_dead_edges, at cfgrtl.c:2219

gcc.c-torture/compile/20010518-1.c:205: Internal compiler error in delete_insn, at cfgrtl.c:140
 with -O1, -Os and -O2.  (This is the 20010518-1.c I recently
told you about.  It's on 3.1 too.  I'll test your "split_insn
fix" <URL:http://gcc.gnu.org/ml/gcc-patches/2002-03/msg00762.html>
which looks promising.)

No, it doesn't look like this bug is "yours", I just mention it
for completeness since this test fails with cris-axis-elf too
in "your" code area.

I haven't checked other target's test-results, but I see the
i960-coff which built before dies, correlated in time with your
changes.  (Objc doesn't build;  configured with
--enable-languages=c++,f77,java.)  It dies with:

Thanks.
