From 6b370e615ca5b3ef17ed4fe4fa891fab1e2bdd9a Mon Sep 17 00:00:00 2001 From: Benjamin Kramer Date: Thu, 8 Nov 2012 13:58:10 +0000 Subject: Drop the limitation to IEEE floating point types from the fdiv of pow2 -> fmul transform. This is safe for x87 long doubles and ppc double doubles too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167582 91177308-0d34-0410-b5e6-96231b3b80d8 --- lib/Support/APFloat.cpp | 5 ----- 1 file changed, 5 deletions(-) (limited to 'lib/Support/APFloat.cpp') diff --git a/lib/Support/APFloat.cpp b/lib/Support/APFloat.cpp index 43c68f4d1d..7e8b4a3d0d 100644 --- a/lib/Support/APFloat.cpp +++ b/lib/Support/APFloat.cpp @@ -3553,11 +3553,6 @@ void APFloat::toString(SmallVectorImpl &Str, } bool APFloat::getExactInverse(APFloat *inv) const { - // We can only guarantee the existence of an exact inverse for IEEE floats. - if (semantics != &IEEEhalf && semantics != &IEEEsingle && - semantics != &IEEEdouble && semantics != &IEEEquad) - return false; - // Special floats and denormals have no exact inverse. if (category != fcNormal) return false; -- cgit v1.2.3
