History

Chris Lattner 0832f2635a 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. llvm-svn: 23671		2005-10-09 05:58:56 +00:00
