Chad Rosier 478b06c980 When fast iseling a GEP, accumulate the offset rather than emitting a series of ... ADDs. MaxOffs is used as a threshold to limit the size of the offset. Tradeoffs being: (1) If we can't materialize the large constant then we'll cause fast-isel to bail. (2) Too large of an offset can't be directly encoded in the ADD resulting in a MOV+ADD. Generally not a bad thing because otherwise we would have had ADD+ADD, but on Thumb this turns into a MOVS+MOVT+ADD. Working on a fix for that. (3) Conversely, too low of a threshold we'll miss opportunities to coalesce ADDs. rdar://10412592 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@144886 91177308-0d34-0410-b5e6-96231b3b80d8		2011-11-17 07:15:58 +00:00
