Hi All,
I need your help!

After my changes in sched models I got the following:

..../llvm/test/CodeGen/X86/schedule-x86_64.ll:2765:17: error: HASWELL-NEXT: expected string not found in input
; HASWELL-NEXT: btcw %si, (%rdx) # sched: [1:2.75]

  ^

<stdin>:391:2: note: scanning from here
btcw %si, (%rdx) # sched: [6:1.00]
^

The new latency (6) looks more realistic than the current version (1) (rr version has 1 and mr version has 6) but throughput is unclear in both versions. What should I do? If I keep my version there could be to many changes in the current tests. Is it OK?
