Instruction scheduling itinerary for Intel Atom. 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.

PR3739, part 2: Use an explicit store to spill XMM registers. (Previously, the code tried to use "push", which doesn't exist for XMM registers.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72836 91177308-0d34-0410-b5e6-96231b3b80d8 2009-06-04 02:32:04 +00:00
