------- Comment #1 from zsojka at seznam dot cz 2010-08-30 19:40 -------
Created an attachment (id=21596)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21596&action=view)
reduced testcase
$ gcc -O1 -fvar-tracking-assignments -fcse-follow-jumps -frerun-cse-after-loop
-fschedule-insns2 -fselective-scheduling2 -funroll-all-loops pr45454.c
This ICE happens quite often with similiar flags.

------- Comment #2 from jakub at gcc dot gnu dot org 2010-09-02 10:48 -------
Why are you using -fvar-tracking-assignments together with selective
scheduling?
It is known not to work (and that's why it isn't enabled with -g).

I wasn't sure if I should open this bugreport, but the message isn't clear (I
didn't understand "changes selective scheduling" as "causes crashes and/or
wrong code"). I don't know it's broken.
The compiler asked me to do so - "Please submit a full bug report"...

------- Comment #4 from aoliva at gcc dot gnu dot org 2010-09-05 20:44 -------
When I first tried to make sel-sched work with VTA, we didn't create
dependencies of non-debug insns on debug insns. Now we do. Other schedulers
know that these deps don't prevent insn movement, just signal the need for
resetting debug insns. sel-sched doesn't know how to deal with that yet,
that's why it fails more noisily now. Looking into it, but no promises.
