            Bug ID: 23680
           Summary: mftb instruction is/isn't deprecated?
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: PowerPC
          Assignee: unassignedbugs at nondot.org
          Reporter: echristo at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

So the CPU document seems to say that the instruction is deprecated, though
there's this patch that went into gas last year:

https://sourceware.org/ml/binutils/2014-11/msg00383.html

that makes it no longer deprecated on "a different reading".

We should probably agree with each other here.
