Jakob Stoklund Olesen 6d9fe79afe Reapply r185393. ... Original commit message: Remove floating point computations from SpillPlacement.cpp. Patch by Benjamin Kramer! Use the BlockFrequency class instead of floats in the Hopfield network computations. This rescales the node Bias field from a [-2;2] float range to two block frequencies BiasN and BiasP pulling in opposite directions. This construct has a more predictable behavior when block frequencies saturate. The per-node scaling factors are no longer necessary, assuming the block frequencies around a bundle are consistent. This patch can cause the register allocator to make different spilling decisions. The differences should be small. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186434 91177308-0d34-0410-b5e6-96231b3b80d8		2013-07-16 18:26:15 +00:00
