GCC trunk gets a ICE when building SPEC CPU2000 test 176.gcc with "-O2
-fmodulo-sched -fselective-scheduling" as demonstrated by a minimized testcase
that I'll attach to this PR.
elm3b149% /home/janis/tools/gcc-trunk-anonsvn/bin/gcc -O2 -fmodulo-sched
-fselective-scheduling -c bug.c
bug.c: In function ‘unroll_loop’:
bug.c:63:1: internal compiler error: in move_bb_info, at sel-sched-ir.c:4968
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
The ICE begins with this patch:

With GCC 4.4.2 using the same options, the minimized testcase compiles cleanly
and 176.gcc compiles and executes successfully.

------- Comment #3 from abel at gcc dot gnu dot org 2009-12-24 07:39 -------
The problem was that the failing assert is actually too strict, when an empty
block is removed, its predecessor could be outside the region. After fixing
this, I have also further robustified the function to expect empty blocks with
no succs or preds, as this problem showed itself yet another time via the
single failed test of the patch on ia64.
* sel-sched-ir.c (maybe_tidy_empty_bb): Do not delete empty blocks
that have no predecessors nor successors. Do not call move_bb_info
for empty blocks outside of current region.
