Lang Hames 58c62e1dba [ADT] Fix PR20728 - Incorrect APFloat::fusedMultiplyAdd results for x86_fp80. ... As detailed at http://llvm.org/PR20728, due to an internal overflow in APFloat::multiplySignificand the APFloat::fusedMultiplyAdd method can return incorrect results for x87DoubleExtended (x86_fp80) values. This commonly manifests as incorrect constant folding of libm fmal calls on x86. E.g. fmal(1.0L, 1.0L, 3.0L) == 0.0L (should be 4.0L) This patch fixes PR20728 by adding an extra bit to the significand for intermediate results of APFloat::multiplySignificand, avoiding the overflow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@222374 91177308-0d34-0410-b5e6-96231b3b80d8		2014-11-19 19:15:41 +00:00
