Evgeniy Stepanov 98726c311b [LICM] Don't create more than one copy of an instruction per loop exit block when sinking. ... Fixes exponential compilation complexity in PR19835, caused by LICM::sink not handling the following pattern well: f = op g e = op f, g d = op e c = op d, e b = op c a = op b, c When an instruction with N uses is sunk, each of its operands gets N new uses (all of them - phi nodes). In the example above, if a had 1 use, c would have 2, e would have 4, and g would have 8. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211673 91177308-0d34-0410-b5e6-96231b3b80d8		2014-06-25 07:54:58 +00:00
