Bug ID: 35639
Summary: [X86] CompleteModel scheduler models still missing
OS: Windows NT
Component: Backend: X86
Assignee: unassignedbugs at nondot.org
Reporter: llvm-dev at redking.me.uk
CC: andrew.v.tischenko at gmail.com, llvm-bugs at lists.llvm.org
Tablegen appears to consider an instruction as scheduled if it has either an
itinerary or a sched class, allowing us to set the CompleteModel = 1 flag. But
given that x86 models use itineraries OR the classes, they might not actually
be tagged with both, this should raise an error.
