[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"' -scooter -------------- next part -------------- A non-text attachment was scrubbed...

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.

Not sure how the same message got sent twice. :-) -scooter On Oct 16, 2007, at 12:00 AM, Evan Cheng wrote:> This is a scheduler assertion.
