[LLVMdev] The one remaining bug keeping CellSPU from release...

[Evan Cheng]

This is a scheduler assertion. It means a value (virtual register) use  
is somehow scheduled before its definition.

Please run llc in gdb. Call dumpSchedule() to print out the schedule.  
Also please let me know which node it is processing at the time of the  
assertion.
