Chris Lattner b26c215c05 Change addRange and join to be a little bit smarter. In particular, we don't ... want to insert a new range into the middle of the vector, then delete ranges one at a time next to the inserted one as they are merged. Instead, if the inserted interval overlaps, just start merging. The only time we insert into the middle of the vector is when we don't overlap at all. Also delete blocks of live ranges if we overlap with many of them. This patch speeds up joining by .7 seconds on a large testcase, but more importantly gets all of the range adding code into addRangeFrom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@15141 91177308-0d34-0410-b5e6-96231b3b80d8		2004-07-23 19:38:44 +00:00
