Hal Finkel 4a1535c038 Make the PPC fast-math sqrt expansion safe at 0 ... In fast-math mode sqrt(x) is calculated using the fast expansion of the reciprocal of the reciprocal sqrt expansion. The reciprocal and reciprocal sqrt expansions use the associated estimate instructions along with some Newton iterations. Unfortunately, as a result, sqrt(0) was being calculated as NaN, which is not correct. Now we explicitly return a result of zero if the input is zero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190624 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-12 19:04:12 +00:00
