Chris Lattner 089c25ccb3 When emiting a CopyFromReg and the source is already a vreg, do not bother ... creating a new vreg and inserting a copy: just use the input vreg directly. This speeds up the compile (e.g. about 5% on mesa with a debug build of llc) by not adding a bunch of copies and vregs to be coallesced away. On mesa, for example, this reduces the number of intervals from 168601 to 129040 going into the coallescer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@23671 91177308-0d34-0410-b5e6-96231b3b80d8		2005-10-09 05:58:56 +00:00
