llvm dev - Oct 2007 - [LLVMdev] The one remaining bug keeping CellSPU from release...

Yup, I've got one remaining bug that holding up the CellSPU release.  
It still has a bunch of warts, but so long as I can get it into shape  
such that llvm-gcc-4.2 compiles all the way through, then we  
collectively have something with which to work.

I'm getting the following error from llc, the attachments have llc's  
debug and the .ll files, respectively. Can anyone shed some light on  
what I should look at to track this one down?

/Users/scottm/play/llvm/branches/llvm-spu/lib/CodeGen/SelectionDAG/ 
ScheduleDAG.cpp:406: failed assertion `I != VRBaseMap.end() &&
"Node
emitted out of order - late"'

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.

Evan:

What you requested was in the debug output (sans offending Node), but  
here it is, outside of the attachment. The offending node is  
highlighted:

SU(0): 0xa908760: ch = EntryToken
SU(1): 0xa907600: i32,ch,flag = CopyFromReg 0xa9095d0, 0xa9070e0,  
0xa9095d0:1
     0xa906e30: ch,flag = CopyToReg 0xa908760, 0xa9070e0, 0xa9071f0  
<<--<<--<<--<<--<< Node
     0xa9095d0: ch,flag = inlineasm 0xa906e30, 0xa908570, 0xa908c60,  
0xa9070e0, 0xa9075a0, 0xa9070e0, 0xa906e30:1
SU(2): 0xa909560: ch = CopyToReg 0xa907600:1, 0xa909500, 0xa907600
SU(3): 0xa907ff0: ch = BRZ 0xa907600, 0xa906f10, 0xa909560

0xa906e30: ch,flag = CopyToReg 0xa908760, 0xa9070e0, 0xa9071f0

Not sure how the same message got sent twice. :-)
