Evan Cheng d4f759696d Add a really faster pre-RA scheduler (-pre-RA-sched=linearize). It doesn't use ... any scheduling heuristics nor does it build up any scheduling data structure that other heuristics use. It essentially linearize by doing a DFA walk but it does handle glues correctly. IMPORTANT: it probably can't handle all the physical register dependencies so it's not suitable for x86. It also doesn't deal with dbg_value nodes right now so it's definitely is still WIP. rdar://12474515 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166122 91177308-0d34-0410-b5e6-96231b3b80d8		2012-10-17 19:39:36 +00:00
