Bug ID: 35546
Summary: [X86] Warn if a scheduling instregex fails to match
any instruction
Product: libraries
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: Backend: X86

Working on the scheduler models recently I've noticed several cases where typos
in instregex entries have meant it failed to match any instruction.
It would be very useful if tablegen reported a warning/error if the instregex
fails to match any instruction.
