Evan Cheng 134982daa9 More accurate estimate / tracking of register pressure. ... - Initial register pressure in the loop should be all the live defs into the loop. Not just those from loop preheader which is often empty. - When an instruction is hoisted, update register pressure from loop preheader to the original BB. - Treat only use of a virtual register as kill since the code is still SSA. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116956 91177308-0d34-0410-b5e6-96231b3b80d8		2010-10-20 22:03:58 +00:00
