Chris Lattner 8bfc4299c2 Stop explicitly scheduling domfrontier before the loop passes, ... since none of them use it. With this, we now only run domfrontier (an N^2 analysis) 3 times at clang -O3: once for "early" per-function cleanup, once at the start of the per-function pipeline to support SRoA, and once late because the EHPrepare class uses it. EHPrepare needs to stop using it, this is silly and wasteful. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112420 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-29 07:05:51 +00:00
