2012-02-01Instruction scheduling itinerary for Intel Atom.Andrew Trick
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
2010-01-07Fix rdar://7517201, a regression introduced by r92849.Chris Lattner
When folding a and(any_ext(load)) both the any_ext and the load have to have only a single use. This removes the anyext-uses.ll testcase which started failing because it is unreduced and unclear what it is testing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92950 91177308-0d34-0410-b5e6-96231b3b80d8
