Evan Cheng 11e8b74a7a - Add a hook for target to determine whether an instruction def is ... "long latency" enough to hoist even if it may increase spilling. Reloading a value from spill slot is often cheaper than performing an expensive computation in the loop. For X86, that means machine LICM will hoist SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON instructions. - Enable register pressure aware machine LICM by default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116781 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-19 00:55:07 +00:00
