Chris Lattner e7d7e13bf7 implement some fixme's: when deleting an instruction with ... an entry in the nonlocal deps map, don't reset entries referencing that instruction to [dirty, null], instead, set them to [dirty,next] where next is the instruction after the deleted one. Use this information in the non-local deps code to avoid rescanning entire blocks. This speeds up GVN slightly by avoiding pointless work. On 403.gcc this makes GVN 1.5% faster. llvm-svn: 60256		2008-11-29 22:02:15 +00:00
