* Instruction scheduling itinerary for Intel Atom.Andrew Trick2012-02-011-192/+287
| | | | | | | | | | | | | | Adds an instruction itinerary to all x86 instructions, giving each a default latency of 1, using the InstrItinClass IIC_DEFAULT. Sets specific latencies for Atom for the instructions in files X86InstrCMovSetCC.td, X86InstrArithmetic.td, X86InstrControl.td, and X86InstrShiftRotate.td. The Atom latencies for the remainder of the x86 instructions will be set in subsequent patches. Adds a test to verify that the scheduler is working. Also changes the scheduling preference to "Hybrid" for i386 Atom, while leaving x86_64 as ILP. Patch by Preston Gurd! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149558 91177308-0d34-0410-b5e6-96231b3b80d8

* rework the rotate-by-1 instructions to be defined like theChris Lattner2010-11-061-16/+16
| | | | | | | | | | | | | | shift-by-1 instructions, where the asmstring doesn't contain the implicit 1. It turns out that a bunch of these rotate instructions were completely broken because they used 1 instead of $1. This fixes assembly mismatches on "rclb $1, %bl" and friends, where we used to generate the 3 byte form, we now generate the proper 2-byte form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118355 91177308-0d34-0410-b5e6-96231b3b80d8
